Do you ever look back at your early twenties and cringe at the money mistakes you made?
Or wonder why we were taught trigonometry instead of how money works in the real world?
You’re not alone.
Most of us stumble through our financial journey learning lots of expensive lessons the hard way.
But what if someone handed you a roadmap when you turned 21?
The principles you’re about to read could save you years of financial stress and thousands of pounds in mistakes.
Some might seem obvious now, but trust me – they weren’t when I was blowing my first paycheck on things I can’t even remember buying.
Pay Yourself First
This might sound backwards, but hear me out.
Most people pay everyone else first – rent, bills, subscriptions and that expensive coffee habit.
Then they wonder where their money went.
They treat savings like an afterthought, something you do with whatever’s left over at the end of the month.
Here’s the problem: there’s never anything left over.
Smart people flip this around. They set aside money for themselves before anything else gets paid.
Even if it’s just £20 from your first paycheck, make it happen.
Set up an automatic transfer for the day after payday, so the money gets put straight in your savings before you can spend it.
Let’s say you earn £1,800 per month.
Instead of hoping you’ll have money left for savings, immediately move £50 to a separate account.
Now you’re living on £1,750, and you’ve just guaranteed you’ll save £600 this year.
Your future self will thank you for starting this habit early.

Paying yourself first doesn’t mean ignore your bills and other responsibilities of course.
You’ll need to budget so you know how much you can put aisde.
Start a Side Hustle
Your 9-to-5 job shouldn’t be your only income source.
Whether it’s freelance writing, selling handmade crafts, or walking dogs in your neighborhood, having multiple income streams protects you. Plus, it gives you skills and confidence you can’t get from a regular job.
Think about it this way: if your main job disappears tomorrow, what happens to your income?
If the answer is “it goes to zero,” you’re putting all your eggs in one basket.
Think about what skills you have from your day job that you could use on the side.
A teacher could start tutoring students online for £25 per hour. Only working 5 extra hours per week, that extra £500 per month would help increase savings or investment contributions and take a proper holiday each year. And if the worst happens with the day job there would be a fall back option in place.
The best time to start? Right now, while you’re young and have energy to burn. Your side hustle doesn’t need to replace your main income immediately.
Start small, learn the ropes, and grow it over time.
Modern technology makes this easier than ever. You can sell products on Etsy, offer services on Fiverr, or create content on YouTube. The key is picking something that matches your skills and interests.
For detailed strategies on building income streams that actually work, read our comprehensive guide to profitable side hustles.

Small Habits Add Up
Think £3 coffee purchases don’t matter? Think again.
That daily coffee costs £1,095 per year. Invested in an index fund averaging 7% returns, that becomes £14,700 after 10 years. Keep it going for 30 years, and you’re looking at £101,073.
I’m not saying never buy coffee. Just be intentional about where your money goes.
The same logic applies to subscriptions you’ve forgotten about. That £9.99 Netflix subscription you share with three friends? Fine. But when you add Spotify Premium, Amazon Prime, Disney+, and that gym membership you used twice, suddenly you’re spending £60+ per month on services.
Here’s a simple exercise: write down every recurring payment you make. Include everything – subscriptions, insurance, phone bills, coffee shop loyalty programs. Add them up. Most people discover they’re spending £200-300 per month on things they barely use.
The magic happens when you redirect these small amounts toward building wealth instead of funding corporate profits.
I found out that I was wasting thousands a year on spending I could easily cut out and not notice a difference to my lifestyle. Here’s how:
Track Your Spending
You can’t improve what you don’t measure.
Download a spending app or use a simple spreadsheet. Track every penny for one month. You’ll be shocked at where your money actually goes.
Most people think they know their spending patterns. They’re usually wrong by hundreds of pounds per month.
Use apps like Monzo, Starling Bank, or even a simple Notes app on your phone. The method doesn’t matter – consistency does. Record every transaction, no matter how small.
After one month, categorise your spending:
- Housing (rent, utilities, insurance)
- Food (groceries, restaurants, takeaway)
- Transportation (car payments, fuel, public transport)
- Entertainment (movies, bars, hobbies)
- Shopping (clothes, gadgets, random purchases)
Look for patterns. Are you spending more on Uber Eats than groceries? Do you buy clothes every week but never wear half of them? These insights are worth their weight in gold.
The goal isn’t to judge yourself harshly. It’s to make conscious decisions about your money instead of wondering where it all went.
Live Below Your Means
This doesn’t mean living like a hermit.
It means spending less than you earn, consistently. If you make £2,000 a month, live on £1,700. Use the difference to build your future.
Lifestyle inflation is real. Don’t let your spending grow faster than your income. The moment you get a raise, most people immediately upgrade their lifestyle to match. New apartment, fancier car, more expensive restaurants. Before they know it, they’re spending every penny of their higher income.
Smart people take a different approach. A promotion means extra money to put away for future you. You can still use some to treat yourself, after all, you deserve it. But spending it all and increasing your day to day living costs is an easy way to get trapped financially.
Living below your means doesn’t require extreme frugality. It requires being intentional about your biggest expenses:
Housing: Aim to spend no more than 30% of your income on rent or mortgage payments. If you’re paying 50% for a fancy flat, you’re setting yourself up for financial stress.
Transportation: Buy reliable used cars instead of financing new ones. A 3-year-old car gives you 90% of the benefits at 60% of the cost.
Food: Cook at home most nights, but don’t feel guilty about the occasional restaurant meal. Balance is key.
The money you don’t spend today becomes the money that funds your dreams tomorrow.
Not All Debt Is Bad
Your school taught you that debt equals danger. That’s not the whole story.
Debt for education, a house, or starting a business can be good investments. These types of debt help you build wealth over time. A mortgage lets you own property that appreciates in value. Student loans fund education that increases your earning potential. Business loans help you create income streams.
Credit card debt for clothes and holidays? That’s the stuff that ruins lives.
The difference comes down to what happens after you borrow the money. Good debt helps you make more money or build assets.
Bad debt funds consumption that provides no long-term value.
Understanding this distinction helps you make smarter borrowing decisions. When evaluating debt, ask yourself: “Will this help me earn more money or build wealth in the future?”
For more check out our guide to getting out of debt.
Automate Your Finances
Set up automatic transfers to your savings account on payday.
When money moves automatically, you can’t spend it on impulse purchases. It’s like paying yourself first, but without the willpower required.
Start with whatever you can afford, even if it’s just £25 per month. The amount matters less than building the habit. You can always increase it later.
Here’s how to set up a bulletproof automation system:
Day 1 (Payday): Automatic transfer to emergency fund savings account Day 2: Automatic transfer to investment account
Day 5: Automatic payment of all fixed bills (rent, utilities, insurance) Day 10: Automatic transfer to short-term savings goals (holiday fund, car repair fund)
This approach eliminates decision fatigue and removes temptation from the equation.
The beauty of automation is that it works even when you’re busy, stressed, or tempted to spend money elsewhere. Your financial future gets built in the background while you focus on living your life.
Most banks offer free automatic transfers. Set them up once, and your money management becomes effortless.
Invest Early, Invest Often
Time is your biggest advantage when you’re young.
Thanks to compound interest, £100 invested at 21 is worth more than £500 invested at 35. The math is incredible when you see it in action.
Let’s break this down with real numbers:
Early Starter: Invests £200 per month from age 22 to 32 (10 years), then stops. Total contributions: £24,000.
Late Starter: Invests £200 per month from age 32 to 62 (30 years). Total contributions: £72,000.
Assuming 7% annual returns, the early starter ends up with more money at retirement despite contributing £48,000 less. That’s the power of compound interest and time.
You don’t need thousands to start. Many investment platforms let you begin with £20. Vanguard, Fidelity, and Hargreaves Lansdown all offer low-cost index funds perfect for beginners.
The biggest mistake young people make is thinking they need to understand everything before they start. You don’t. Start with simple, diversified index funds and learn as you go.
Here’s a beginner-friendly approach:
- Open an ISA account with a reputable provider
- Choose a global index fund (FTSE Global All Cap is popular)
- Set up automatic monthly contributions
- Ignore the daily fluctuations and let time do the work
Remember, you’re not trying to get rich quick. You’re building long-term wealth through consistent, boring investments.
For step-by-step guidance on getting started, watch my beginners guide to investing:
Learn to Cook Food at Home
Takeaways and restaurant meals destroy budgets faster than anything else.
Learning basic cooking skills saves you thousands per year. Plus, you’ll eat healthier and impress dates with your culinary talents.
The average person spends £2,500 per year on restaurant meals and takeaways. That’s over £200 per month. For many young people, food represents their second-largest expense after housing.
Compare these costs:
- Homemade pasta dinner: £2.50
- Restaurant pasta: £12-15
- Homemade sandwich: £1.50
- Cafe sandwich: £4-6
- Homemade coffee: £0.30
- Coffee shop coffee: £3-4
The savings add up quickly.
Start with simple recipes and build from there. Master these five meals first:
- Pasta with basic tomato sauce
- Stir-fry with rice
- Scrambled eggs and toast
- Basic curry with vegetables
- Simple roast chicken and vegetables
YouTube is your friend here. Channels like “Brothers Green Eats” and “Bon Appétit” make cooking approachable for beginners.
Batch cooking on Sundays saves time and money during busy weekdays. Prepare large portions and freeze individual servings. Future you will thank present you when you come home exhausted and have a homemade meal ready in minutes.
Set Short and Long Term Goals
Dreams without deadlines are just wishes.
Want to buy a house? Figure out exactly how much you need and when you want it. Then work backwards to create a savings plan.
Having specific targets makes it easier to say no to unnecessary spending. When you know that jacket costs two weeks of house deposit savings, the decision becomes clearer.
Here’s how to set effective financial goals:
Short-term (1 year or less):
- Build £1,000 emergency fund
- Pay off credit card debt
- Save for holiday or car repairs
Medium-term (1-5 years):
- Save house deposit
- Build 6-month emergency fund
- Start investing consistently
Long-term (5+ years):
- Buy property
- Build retirement fund
- Achieve financial independence
Make your goals SMART: Specific, Measurable, Achievable, Relevant, Time-bound.
Instead of “save more money,” try “save £5,000 for a house deposit by December 2026.” This gives you a clear target (£5,000), deadline (December 2026), and purpose (house deposit).
Break big goals into smaller milestones. Saving £5,000 feels overwhelming, but saving £417 per month feels manageable. Better yet, that’s about £14 per day – the cost of lunch and a coffee.
Write your goals down and review them monthly. Studies show people who write down their goals are 42% more likely to achieve them.
Create a Budget and Stick to It
Budgeting isn’t about restricting your fun. It’s about giving every pound a purpose.
Use the 50/30/20 rule as a starting point: 50% for needs, 30% for wants, 20% for savings and debt repayment.
Adjust the percentages based on your situation, but stick to the framework.
Many people resist budgeting because they think it’s complicated or restrictive. It doesn’t have to be either. A good budget actually gives you more freedom because you know exactly what you can afford.
Here’s a simple budgeting method that works:
Step 1: Calculate your after-tax monthly income
Step 2: List all fixed expenses (rent, insurance, phone, etc.)
Step 3: Estimate variable expenses (food, entertainment, shopping)
Step 4: Allocate money for savings and debt payments
Step 5: Track actual spending and adjust as needed
Let’s say you earn £2,000 per month after tax:
Needs (50% = £1,000):
- Rent: £650
- Utilities: £80
- Groceries: £150
- Transport: £120
Wants (30% = £600):
- Restaurants: £200
- Entertainment: £150
- Shopping: £150
- Hobbies: £100
Savings (20% = £400):
- Emergency fund: £200
- Investments: £150
- Holiday fund: £50
This framework ensures you cover essentials while still enjoying life and building wealth.
The key is tracking your actual spending against your budget. Most budgets fail because people set them and forget them. Review yours weekly for the first month, then monthly after that.
Credit Cards Aren't Free Money
This should be obvious, but apparently it’s not.
Credit cards are tools, not extensions of your income. Use them for convenience and rewards, but pay them off in full every month.
Missing payments destroys your credit score and costs you thousands in interest. Credit card companies make billions from people who don’t understand this simple rule.
Consider the true cost of credit card debt:
- Average credit card interest rate: 22% APR
- Average credit card debt: £2,600
- Minimum payment (3%): £78 per month
- Time to pay off: 14 years
- Total interest paid: £4,760
That £2,600 debt actually costs £7,360. You’re paying nearly three times the original amount.
Smart credit card use looks different:
- Pay off the full balance every month
- Use cards for purchase protection and rewards
- Never spend more than you can afford to pay cash
- Set up automatic payments to avoid late fees
Credit cards can actually help build wealth when used properly. Cashback cards give you 1-2% back on purchases you’d make anyway. Travel cards offer valuable perks and protections. Building good credit history helps you get better rates on mortgates and loans.
The rule is simple: if you can’t afford to pay cash for something, you can’t afford to put it on a credit card either.
Anyone Can Be Financially Literate
You don’t need a finance degree to manage money well.
Read books, listen to podcasts, watch YouTube videos.
The information is out there, and most of it is free.
Financial literacy is a skill you can learn, just like riding a bike or cooking pasta. The difference is that improving your financial knowledge can literally make you hundreds of thousands of pounds over your lifetime.
Start with these beginner-friendly resources:

Podcasts: Check out my favourites here.

Spend 30 minutes per week learning about money.
That’s just 26 hours per year – less time than most people spend watching Netflix in a week.
Focus on understanding these core concepts first:
- Compound interest and why it matters
- The difference between good and bad debt
- How taxes affect your investments
- Basic investment principles
- Insurance fundamentals
Financial education is an investment that pays dividends forever. The concepts you learn in your twenties will benefit you for the next 60+ years.
Knowledge Is Power
The more you know about money, the more you’ll have.
Understanding concepts like compound interest, inflation, and tax optimisation gives you massive advantages over people who ignore their finances.
Consider these real-world examples of how financial knowledge creates wealth:
Tax optimisation: Understanding ISAs and pension contributions can save you thousands in taxes annually. Someone earning £30,000 who maximises their pension contributions saves £600 per year in tax relief.
Investment knowledge: Knowing the difference between active and passive funds can save you 1-2% in fees annually. On a £10,000 portfolio, that’s £100-200 per year in your pocket instead of the fund manager’s pockets.
Debt management: Understanding how to negotiate better rates or transfer balances can save hundreds on existing debt. Moving £3,000 from a 22% credit card to a 0% balance transfer saves £660 per year.
Insurance literacy: Understanding what coverage you actually need prevents over-insuring while ensuring you’re protected. This can save £500+ annually on unnecessary policies.
The people who get rich aren’t necessarily the highest earners. They’re the ones who understand how money works and use that knowledge to their advantage.
Financial knowledge compounds just like money. Each concept you learn builds on previous ones, creating a framework for making better decisions throughout your life.
You Don't Have to Be Rich to Invest
This might be the biggest myth about investing.
You don’t need to be wealthy to start building wealth. Many investment platforms have no minimum requirements.
Starting small is better than not starting at all. The biggest barrier isn’t money – it’s the belief that you need a lot of money to begin.
Here’s how you can start investing with small amounts:
£25 per month: Open a Stocks and Shares ISA with Vanguard. Invest in a global index fund. After 30 years at 7% returns, you’ll have £76,122.
£50 per month: Use the same strategy but double the contribution. Your 30-year total becomes £152,244.
£100 per month: This grows to £304,488 over 30 years.
Notice how doubling your contribution doubles your end result? That’s because the percentage returns remain constant regardless of your starting amount.
Many platforms now offer fractional shares, meaning you can buy portions of expensive stocks. Want to own Apple but can’t afford the full £150+ share price? Buy £10 worth instead.
Robo-advisors like Nutmeg and Wealthify make investing even easier. They automatically create diversified portfolios based on your risk tolerance and goals. Minimum investments start at £1.
The key is starting, even if it feels insignificant. That £25 monthly investment might seem tiny now, but it builds the habit and knowledge you’ll need when your income grows.
For detailed guidance on starting your investment journey with limited funds, check out the YouTube video above.
Spending Money Isn't Inherently Bad
Money is meant to be spent, just spend it wisely.
Buy experiences over things. Invest in your health, education, and relationships. These purchases often provide returns that last a lifetime.
The key is being intentional about your spending choices. Not all purchases are created equal. Some expenses are investments in your future self, while others are just consumption.
Smart spending includes:
- Education and skill development
- Health and fitness
- Quality tools that last years
- Experiences that create memories
- Anything that increases your earning potential
Questionable spending includes:
- Impulse purchases you forget about
- Status symbols that drain your budget
- Subscriptions you don’t use
- Eating out when you have food at home
- Shopping for entertainment
This doesn’t mean never buying anything fun. It means being conscious about your choices. When Sophie wanted a £400 designer handbag, she waited a month and realised she’d rather put that money toward her holiday fund.
Create a “joy spending” category in your budget. Allocate money specifically for purchases that make you happy, guilt-free. This prevents overspending while ensuring you still enjoy your money.
Remember, the goal isn’t to hoard money forever. It’s to spend it on things that align with your values and long-term goals.
This is a great watch for learning more about spending vs saving.
Don't Try to Keep Up with the Joneses
Social media makes everyone’s life look perfect, especially their financial situation.
That friend posting vacation photos might be drowning in credit card debt. That colleague with the fancy car might be living paycheck to paycheck.
Focus on your own financial journey, not other people’s highlight reels. Comparison is the thief of joy – and the destroyer of budgets.
The “Joneses” are often broke. Studies show that people with flashy lifestyles frequently have negative net worth. They own expensive things but have no actual wealth.
Real wealth is usually invisible:
- Money in investment accounts
- Paid-off mortgages
- Emergency funds
- Pension contributions
- Assets that generate income
Meanwhile, fake wealth is highly visible:
- Expensive cars (usually financed)
- Designer clothes and accessories
- Frequent luxury holidays (often on credit)
- Latest gadgets and technology
- Expensive restaurants and entertainment
The person driving the 5-year-old Toyota might have £50,000 invested, while the person in the brand-new BMW might have £20,000 in credit card debt.
Social media amplifies this problem. People share their purchases, not their savings accounts. They post vacation photos, not investment statements.
Create financial goals based on your values, not other people’s spending habits. Define what wealth means to you personally, then work toward that vision.
Your First Paycheck Isn't All Fun Money
Getting your first real job feels amazing. Finally, money in the bank!
But don’t blow it all on celebrations and shopping sprees. Treat that first paycheck as the foundation of your financial future.
Set up your savings and investment accounts before you develop expensive habits. It’s much easier to start good habits than to break bad ones later.
Here’s what to do with your first few paychecks:
Paycheck #1: Set up automatic transfers for savings and investments. Open ISA accounts. Establish your financial infrastructure.
Paycheck #2: Build your emergency fund starter fund (£500-1000). This prevents you from going into debt for small emergencies.
Paycheck #3: Start investing, even if it’s just £25 per month. The sooner you start, the more time compound interest has to work.
Paycheck #4: Now you can celebrate responsibly. Buy something nice for yourself, but within reason.
Many people make the mistake of lifestyle inflation from day one. They get their first £25,000 salary and immediately start living like they make £25,000. This leaves no room for savings or unexpected expenses.
Instead, live like you make £20,000 and save the difference. As your income grows, gradually increase your lifestyle while always maintaining a gap between earning and spending.
Your early career choices set patterns that follow you for decades. Starting with good financial habits makes everything easier later.
A Positive Money Mindset Is Everything
Your beliefs about money shape your financial reality.
If you think money is evil or that rich people are greedy, you’ll subconsciously sabotage your wealth-building efforts. Instead, view money as a tool for creating the life you want.
Money amplifies who you are – it doesn’t change your character. Good people with money do good things. Selfish people with money do selfish things.
Common limiting beliefs that destroy wealth:
- “Money doesn’t buy happiness”
- “Rich people are greedy”
- “I’m not good with money”
- “Investing is too risky”
- “I don’t deserve to be wealthy”
These beliefs become self-fulfilling prophecies. If you believe you’re bad with money, you won’t try to improve. If you think investing is gambling, you’ll keep your money in low-interest savings accounts.
Successful people have different beliefs:
- Money is a tool for freedom and security
- Building wealth lets me help others
- I can learn financial skills like any other skill
- Investing is how I protect my future
- I deserve financial security and success
Your relationship with money started in childhood, influenced by your family’s attitudes and experiences. If your parents stressed about money constantly, you might associate wealth with anxiety. If they never talked about money, you might feel uncomfortable discussing finances.
Recognize where your beliefs come from, then consciously choose new ones that serve your goals. This mental work is just as important as the practical steps.
Educate Yourself About Personal Finance
Take responsibility for your financial education.
Your school probably didn’t teach you about budgeting, investing, or taxes. That’s unfortunate, but it’s not an excuse to stay ignorant.
Books, podcasts, and online courses can fill the gaps in your knowledge. The internet has democratized financial education – you have access to the same information that wealthy people pay advisors thousands to provide.
Create a personal curriculum:
Month 1: Learn budgeting basics and track your spending Month 2: Understand different types of debt and repayment strategies
Month 3: Master the fundamentals of investing and compound interest Month 4: Learn about taxes, ISAs, and pension optimization Month 5: Study insurance needs and estate planning basics Month 6: Explore advanced topics like property investment or business finance
Most financial concepts aren’t actually complicated – they’re just unfamiliar. Once you understand the basic principles, everything else builds logically.
Join online communities like r/UKPersonalFinance on Reddit or Money Saving Expert forums. Reading other people’s questions and success stories accelerates your learning.
Consider taking a formal course. Many universities offer continuing education classes in personal finance. Online platforms like Coursera and Udemy have comprehensive courses for under £50.
The education never stops. Tax laws change, new investment products emerge, and your personal situation evolves. Make financial learning a lifelong habit.
The 24-Hour Rule Stops Impulse Purchases
See something you want? Wait 24 hours before buying it.
This simple rule eliminates most impulse purchases. You’ll be amazed how often you forget about things you “needed” yesterday.
For expensive items, extend this to a week or month. The bigger the purchase, the longer you should wait.
Impulse spending destroys budgets. Retailers spend billions studying how to trigger these purchases. From strategic product placement to limited-time offers, everything is designed to make you buy now without thinking.
The 24-hour rule breaks this cycle. It gives your rational brain time to override your emotional impulses.
Here’s how to implement it effectively:
For purchases under £50: Wait 24 hours For purchases £50-200: Wait one week For purchases over £200: Wait one month
During the waiting period, ask yourself:
- Do I actually need this or just want it?
- Where will I put/use this item?
- Can I afford this without impacting my financial goals?
- Will I still want this in a month?
Often, the answer reveals that you don’t really want the item – you were just caught up in the moment.
For online shopping, use the “save for later” or wishlist features instead of buying immediately. Many retailers will email you discount codes for items you’ve saved, so you might even get a better price by waiting.
Alex saved over £2,000 in his first year using this rule. He realized most of his impulse purchases were emotional responses to stress or boredom, not actual needs.
The rule becomes easier with practice. Eventually, you’ll naturally pause before any non-essential purchase.
Separate Your Emotions from Your Finances
Money decisions based on emotions are usually bad decisions.
Whether you’re feeling stressed, excited, or depressed, take a step back before making financial choices. Create rules for yourself when you’re thinking clearly, then follow them when emotions run high.
Emotions and money are a dangerous combination:
Fear leads to keeping all money in savings accounts, missing out on investment growth.
Greed causes people to chase get-rich-quick schemes and lose their savings.
Stress triggers overspending on comfort purchases that provide temporary relief.
Excitement results in impulse purchases and overconfident investment decisions.
Depression can lead to either complete financial avoidance or reckless spending.
Professional investors use systematic approaches to remove emotions from their decisions. You can do the same with personal finance.
Create an “emotional spending” protocol:
- Recognize when you’re feeling emotional
- Step away from financial decisions for 24-48 hours
- Talk to a trusted friend or write down your thoughts
- Review your financial goals and priorities
- Make decisions based on logic, not feelings
Keep a spending journal for one month. Write down not just what you bought, but how you were feeling when you made the purchase. You’ll likely discover patterns between your emotions and spending habits.
Set up systems that protect you from emotional decisions:
- Automatic investments that continue regardless of market conditions
- Waiting periods for large purchases
- A trusted friend who can talk you through major financial decisions
- Clear written goals you can reference when tempted to deviate
Remember, everyone makes emotional money mistakes sometimes. The key is recognizing the pattern and building systems to minimize the damage.
Build an Emergency Fund of 3-6 Months of Expenses
Life happens. Cars break down, people lose jobs, medical emergencies arise.
Having 3-6 months of living expenses saved gives you options when crisis hits. You won’t need to rely on credit cards or loans to survive.
Start with £1,000 and build from there. This initial amount covers most small emergencies without derailing your other financial goals.
Calculate your monthly essential expenses:
- Rent or mortgage payments
- Utilities (electricity, gas, water, internet)
- Groceries and basic food costs
- Transportation (car payments, insurance, fuel, or public transport)
- Insurance premiums
- Minimum debt payments
- Basic phone plan
Multiply this number by 3-6 to get your emergency fund target. If your essential monthly expenses are £1,200, you need £3,600-7,200 in your emergency fund.
Where to keep your emergency fund:
- High-yield savings account for easy access
- Money market account with debit card access
- Split between savings and premium bonds for larger amounts
- NOT in investments that can lose value when you need the money
The emergency fund isn’t an investment – it’s insurance. You’re not trying to maximize returns; you’re buying peace of mind and financial stability.
Real emergencies include:
- Job loss or reduced income
- Major medical expenses
- Essential home repairs
- Car repairs needed for work
- Family emergencies requiring travel
Non-emergencies include:
- Holidays and travel
- Holiday gifts
- Home renovations
- Upgrading electronics
- Taking advantage of sales
Having an emergency fund changes everything. You’ll sleep better knowing you can handle whatever life throws at you. You’ll also make better financial decisions because you’re not operating from a place of fear.
For specific strategies on building your emergency fund faster, check out our detailed guide to emergency funds.
Use the 50/30/20 Rule: 50% Needs, 30% Wants, 20% Savings
This simple framework takes the guesswork out of budgeting.
50% goes to necessities like rent, groceries, and utilities. 30% covers entertainment, dining out, and hobbies. 20% builds your future through savings and investments.
Adjust these percentages as your income and priorities change, but the framework provides a solid foundation for financial health.
Let’s break down each category:
Needs (50%):
- Housing (rent, mortgage, property taxes)
- Utilities (electricity, gas, water, internet, phone)
- Groceries and basic household items
- Transportation (car payment, insurance, fuel, public transport)
- Insurance (health, life, disability)
- Minimum debt payments
Wants (30%):
- Dining out and takeaway
- Entertainment (movies, concerts, streaming services)
- Hobbies and recreational activities
- Shopping for non-essential items
- Travel and holidays
- Gym memberships and fitness classes
Savings (20%):
- Emergency fund contributions
- Retirement/pension contributions
- Investment account deposits
- Extra debt payments above minimums
- Short-term savings goals (holiday fund, car replacement)
With the cost of living crisis these percentages might need to vary a bit more towards needs, but you still need to make sure you’re putting money away for later.
