The short answer: £1 million earns between £37,500 and £47,500 in interest per year at the best UK savings rates (as of the time of writing), which works out to roughly £3,100-£3,960 a month before tax.
At the current Bank of England base rate of 3.75% (as of April 2026), easy-access savings accounts are paying up to 4.75%, and fixed-rate bonds pay up to 4.70% for one year.
Premium Bonds average around 3.25% tax-free.
Investing the million instead of saving it typically targets 4-7% real returns long term, but with real capital risk.
That’s the headline. The real question is what happens after FSCS protection limits, income tax, and the Personal Savings Allowance chew into those numbers.
Spoiler: you’ll need to split the million across roughly 8 institutions to keep it protected, and you’ll pay tax on most of the interest unless you plan carefully.
Here’s the full breakdown: the rates, the tax, the protection rules, and where to actually put £1m in 2026.

How much interest can you earn on 1 million pounds?
Interest rates move constantly.
As of April 2026, the Bank of England base rate sits at 3.75%, and UK savings rates have stabilised in the 4-5% range for most standard accounts.
Here’s what £1 million earns at different rates:
| Interest rate | Monthly return | Yearly return |
|---|---|---|
| 1.00% | £833 | £10,000 |
| 2.00% | £1,667 | £20,000 |
| 3.00% | £2,500 | £30,000 |
| 3.75% (BoE base) | £3,125 | £37,500 |
| 4.00% | £3,333 | £40,000 |
| 4.50% | £3,750 | £45,000 |
| 4.75% (best easy-access, April 2026) | £3,958 | £47,500 |
| 5.00% | £4,167 | £50,000 |
| 7.50% | £6,250 | £75,000 |
| 10.00% | £8,333 | £100,000 |
Figures assume simple interest on £1,000,000.
Most savings accounts compound interest monthly or annually, which adds a small premium (typically 0.1-0.3% more than the headline AER suggests).
A few things to understand about these numbers:
The 3-5% range is realistic for UK savings accounts right now.
Easy-access, fixed-rate bonds, Cash ISAs and Premium Bonds (tax-free equivalent) all sit roughly in this band in April 2026.
7.5-10% is what you’d aim for with investments, not savings.
The long-term average of a globally diversified stock market is around 7-9% in nominal terms, 4-6% after inflation. You’d take on real capital risk for this.
The base rate is the floor, not the ceiling.
Challenger banks and building societies routinely pay 0.5-1% above base rate to attract deposits. The rates above 5% in the table are what you’d get from higher-risk or locked-in products.
The numbers look clean in a table. They get messy once you bring in FSCS protection and UK tax, which is what the next two sections cover.

FSCS protection: why £1m means 8 accounts
This is the single biggest practical issue for anyone actually parking £1 million in UK savings, and it’s the one most people get wrong.
The Financial Services Compensation Scheme (FSCS) protects up to £120,000 per person, per banking licence. If a UK bank fails, you get up to £120,000 back. Anything above that is unprotected.
£1 million at one bank means £880,000 is unprotected. That’s a non-trivial risk even for a major high street bank.
The workaround is to split the million across multiple institutions:
£120,000 protection limit means £1m needs to be spread across at least 8 banking licences (8 × £120,000 = £960,000)
– Joint accounts get £240,000 protection (£120,000 per person), which halves the number of institutions needed for couples
– Licences matter more than brand names. HSBC and First Direct are the same licence. Halifax, Bank of Scotland and Lloyds are the same licence. Santander and Cahoot are the same licence.
Splitting £120k across Halifax and Lloyds doesn’t give you double protection.
Services exist specifically to solve this problem for high-net-worth savers. You deposit once with them and they automatically spread your money across 30+ partner banks, all within FSCS limits. Minimum deposits are typically £25,000-£100,000 and they take a small management fee (usually 0.1-0.3% per year).
For £1m, using a cash management platform is usually the right move. The alternative is manually opening 8+ savings accounts, tracking 8+ maturity dates, and moving money between them when rates change. Most people can’t be bothered, and that’s how the interest rate drifts down to mediocre over time.
Is a million enough to live on?
The quick answer: yes, £1 million is enough to live on for most people in the UK, if you manage it properly.
At a 4% sustainable withdrawal rate (the classic Trinity Study benchmark, adjusted for UK conditions), £1m gives you £40,000 a year for 30+ years with a high probability of not running out. That’s a comfortable middle-class income in most of the UK, though it’s tighter in London and the South East.
Using the PLSA’s Retirement Living Standards as a benchmark:
– Minimum (£13,400/year single, £21,600 couple): £1m covers this 50+ times over
– Moderate (£31,300 single, £43,100 couple): £1m covers this 23-32 years at 0% real return, much longer if invested sensibly
– Comfortable (£43,900 single, £60,600 couple): £1m covers this 16-23 years, requiring investment returns to stretch further
So “enough to live on” depends entirely on the lifestyle you’re aiming for. Minimum comfort, yes, easily. Comfortable retirement in London with regular travel, only if you pair the £1m with a State Pension and keep most of it invested rather than in cash savings.
The key variables:
– How long you want it to last. £1m at 4% withdrawal sustains 30+ years. At 5% it sustains 20-25 years. At 7% it’s 12-15 years.
– Whether you’re drawing down in retirement or just living off interest. Living off interest alone requires 40-50x your annual spend. Drawdown (spending capital gradually) works with 25x.
– Tax wrappers. £1m held inside a SIPP and Cash ISA is worth a lot more after tax than £1m held in a general investment account.
– The State Pension. The full new State Pension pays £12,570/year (2026/27). For a couple, that’s £25,140 before you touch the £1m.
For a proper breakdown of what income you can sustainably draw, see my retirement income calculator.
Where to keep a million pounds?
Here’s where the real work happens. £1m held badly loses thousands a year to tax, inflation and missed rates. £1m held well earns £40,000+ annually with minimal admin.
The main options for holding cash savings in the UK:
Easy-access savings accounts
– Current best rate (April 2026): 4.75% AER (Tembo Money HomeSaver, includes 1.75% 12-month bonus)
– Access: immediate withdrawal
– FSCS limit: £120,000 per licence
– Best for: 3-6 months of living expenses, or the portion of the £1m you might need to move
Fixed-rate bonds
– Current best rates (April 2026): 4.70% 1yr, 4.65% 2yr, 4.60% 3yr, 4.67% 5yr
– Access: locked in for the term, usually no early withdrawal
– FSCS limit: £120,000 per licence
– Best for: money you definitely won’t need for 12+ months
Cash ISAs
– Current best rate (April 2026): around 4.50% AER on easy-access variants, 4.60-4.70% on fixed
– Access: varies by product
– Tax: interest is tax-free
– Annual contribution limit: £20,000 per tax year
– Best for: growing a tax-free cash position over multiple years (a married couple can contribute £40,000/year combined)
Premium Bonds
– Prize rate (April 2026): 3.25% annual average (but tax-free, so equivalent to ~5.4% for a higher-rate taxpayer)
– Access: withdrawal in 8-10 days typically
– FSCS limit: £1m (backed by HM Treasury, not FSCS, but with equivalent protection)
– Annual purchase limit: £50,000 per person (£100,000 per couple)
– Best for: a portion of the cash allocation for higher-rate and additional-rate taxpayers who’ve used their PSA
Gilts and corporate bonds
– Current gilt yields (April 2026): 10-year UK gilt yields around 4.3%
– Access: tradeable on secondary market, but prices fluctuate
– Tax: interest is taxable but no CGT on gilt capital gains
– Best for: large cash positions outside ISA wrappers, particularly for additional-rate taxpayers
For £1m, the sensible split isn’t all in one product.
It’s spread across several, with allocation driven by when you need access and what wrapper protects it from tax.
I’ve broken down a realistic case study below.
£1m allocation: a realistic 2026 example
This is how someone might actually split £1m today to balance access, yield and tax efficiency. Adjust to your own circumstances. Not financial advice, just an illustrative example.
Assumptions:
– Single person, higher-rate taxpayer (40% tax band)
– Already has pension and ISA exposure from previous years
– Needs £40-50k/year drawdown, wants to live off interest without eroding capital
– Priorities: FSCS protection, tax efficiency, reasonable access
| Allocation | Product | Amount | Rate (Apr 2026) | Annual interest | Tax treatment |
|---|---|---|---|---|---|
| Emergency buffer | Easy-access savings (split across 2 banks) | £100,000 | 4.75% | £4,750 | Taxable, covered by £500 PSA + higher-rate bands |
| Tax-free cash | Cash ISA (current year) | £20,000 | 4.60% | £920 | Tax-free |
| Medium-term | Fixed-rate bonds (2-3yr, split across 6 banks) | £510,000 | 4.65% avg | £23,715 | Taxable |
| Tax-free prizes | Premium Bonds | £50,000 | 3.25% avg | £1,625 | Tax-free |
| Long-term investment | Stocks & Shares ISA (current year) | £20,000 | 6-8% target | £1,200-1,600 | Tax-free |
| Long-term investment | General Investment Account (GIA) | £250,000 | 6-8% target | £15,000-20,000 | CGT + dividend tax |
| Short-term liquidity | Cash management platform (Insignis/Flagstone) | £50,000 | 4.60% avg | £2,300 | Taxable |
| Total | £1,000,000 | ~4.9% blended | £49,510-£54,910 | Mixed |
Blended yield of ~4.9% across protection-limit-aware allocation, with meaningful tax efficiency from ISA and Premium Bonds wrappers. Annual interest/growth of around £50k before tax.
After tax (higher-rate taxpayer scenario): roughly £38,000-£42,000 net per year.
Two things to note about this split:
1. 8+ banking licences are used once you count the fixed-rate bonds, easy-access accounts, and the cash management platform’s partner banks. FSCS protection is preserved across the whole £1m.
2. ISA allowances can’t be front-loaded. The £20,000 annual limit means building tax-free cash and investment positions takes multiple years. The case study above reflects one tax year’s contribution.
Are there any tax problems I should know about?
Interest earned on £1m is, in most cases, taxable. Here’s how the UK tax system actually treats it.
Personal Savings Allowance (PSA):
– Basic-rate taxpayers (20%): first £1,000 of interest tax-free each year
– Higher-rate taxpayers (40%): first £500 of interest tax-free each year
– Additional-rate taxpayers (45%): £0 PSA, all interest is taxable
At 4.75% on £1m, you’re earning £47,500 in interest. If that’s held in standard savings accounts, your PSA covers £500-£1,000 of it. The rest is taxed at your marginal rate.
What that means in practice:
| Taxpayer | Gross interest (£1m at 4.75%) | Tax-free (PSA) | Taxable interest | Tax owed | Net interest |
|---|---|---|---|---|---|
| Basic (20%) | £47,500 | £1,000 | £46,500 | £9,300 | £38,200 |
| Higher (40%) | £47,500 | £500 | £47,000 | £18,800 | £28,700 |
| Additional (45%) | £47,500 | £0 | £47,500 | £21,375 | £26,125 |
Tax turns a 4.75% headline rate into a 2.6-3.8% net rate depending on your band.
How to pay less tax on interest:
1. Cash ISA. £20,000 per tax year, interest is entirely tax-free. Over time this adds up (£100k across 5 years, earning tax-free interest forever).
2. Premium Bonds. Prizes are tax-free. £50,000 limit per person. For higher-rate taxpayers, the 3.25% average prize rate is equivalent to a 5.4% gross interest rate.
3. Spouse allowance. Split savings between partners to use both PSAs and both £20k ISA limits.
4. Pension (SIPP). If retirement is the goal, pension contributions give you 20-45% tax relief going in. £1m inside a SIPP is worth significantly more after tax than £1m in general savings.
5. Investments not savings. Capital gains have their own allowance (£3,000 for 2026/27) and lower rates (18-24% vs 20-45% on interest). Dividends have a £500 allowance. Long-term, investing a portion of the million inside and outside an ISA is more tax-efficient than pure savings.
If the numbers above sound painful, that’s the point. The UK tax system is specifically designed to reward investing through wrappers (ISA, SIPP) over straight savings. £1m held entirely in taxable savings accounts is tax-inefficient, regardless of how good the rate is.
For £1m positions, getting an accountant or chartered financial planner involved is almost always worth the fee.
How to get your first million?
If you’re reading this because you’d like to build towards £1m rather than deploy one, here’s the maths.
Compound interest at realistic investment returns (7% average, long-term):
– Starting from £0, investing £500/month, you hit £1m in around 35 years
– Starting from £0, investing £1,000/month, you hit £1m in around 27 years
– Starting from £0, investing £2,000/month, you hit £1m in around 20 years
– Starting from £100,000 (say, inherited or property proceeds), investing £1,000/month on top, you hit £1m in around 20 years
Three things that determine whether you make it:
1. Time in the market. Starting at 25 vs starting at 45 is roughly the difference between needing £500/month or £2,500/month to hit £1m by 65.
2. Rate of return. A globally diversified index tracker inside a Stocks & Shares ISA is the baseline. Active management, single stocks, and crypto can help or hurt dramatically.
3. Consistency. People who hit £1m don’t time markets. They set up direct debits to ISAs and SIPPs and ignore the news.
Can I retire at 55 with 1 million pounds?
Short answer: yes, £1m is enough to retire at 55 in the UK, if your lifestyle fits the number.
The maths works like this:
– At 4% safe withdrawal rate, £1m gives you £40,000/year, indexed to inflation, with a high chance of lasting 30+ years
– 55 to 67 (State Pension age) is 12 years you need to cover entirely from the £1m
– From 67 onwards, State Pension (£12,570/year in 2026) kicks in alongside the drawdown
Practical considerations for retiring at 55 with £1m:
- Pension access age is rising. If any of the £1m is inside a SIPP or workplace pension, you can access it from age 55 now, but this rises to 57 from April 2028. Plan accordingly if you’re 55 after that date.
- Health and insurance. Pre-State Pension age means you’re funding your own private health cover if you want it, which adds £2-5k/year.
- Sequence of returns risk. Retiring into a bad market (2-3 years of portfolio drawdown at the same time as negative returns) is the biggest risk to early retirement. The solution is usually to hold 2-3 years of spending in cash, so you don’t have to sell investments at a loss.
For the full maths on early retirement with £1m, my Lean FIRE calculator and Coast FIRE calculator both model this precisely.
What can I do with 1m pounds?
Owning £1m forces a decision. Here are the four most common ways UK residents actually deploy it, ranked by what the numbers support:
1. Retire or semi-retire
The most common reason people hit £1m and stop working (or shift to part-time). At 4% sustainable withdrawal, £1m funds a £40,000/year lifestyle indefinitely. This is the core FIRE movement answer.
2. Live off interest, preserve capital
Keeping £1m working in a mix of cash savings, bonds, and investments at a blended 4-6% yield generates £40-60k/year without eroding the principal. You pass the £1m on intact.
3. Property
Buy one or more UK properties outright, either as a home or as buy-to-let. £1m buys roughly 3-5 average UK homes at 2026 prices (average UK house price around £290k), or 1-2 London properties. Yields on buy-to-let are currently 5-7% gross, but mortgage interest rates and capital gains treatment have made this less attractive than it was pre-2020.
4. Reinvest in a business or angel investments
Higher risk, higher potential return. Angel investing, VC, or funding your own business typically targets 2-5x returns over 5-10 years, but with a high failure rate. For £1m, this usually means committing a portion (£100-300k) to business investment and keeping the rest conservative.
What the data doesn’t support: spending £1m on lifestyle inflation. £1m feels like infinite money until you realise that a £100k car, a world cruise, and a new kitchen have eaten 20% of your financial independence.
The people who keep their £1m are the ones who treat it as an income-generating asset, not a spending pot.
Frequently Asked Questions
Final Thoughts
The interest on £1m in the UK in 2026 is between £37,500 and £47,500 per year at standard savings rates, before tax.
After tax it’s usually £26,000-£38,000 net, depending on your band. Properly structured across ISAs, Premium Bonds and investments, you can push that net figure comfortably above £40,000.
Three takeaways if you’ve got £1m to deploy:
1. FSCS protection matters more than the top rate. £120k per licence means at least 8 accounts. Use a cash management platform if the admin isn’t worth it.
2. Tax wrappers compound over time. ISA and SIPP allowances can’t be backdated. Max them every year and the tax-free position compounds.
3. Your biggest enemy is inflation, not market volatility. £1m held entirely in cash at 4.75% is losing real value if inflation runs above that. Some allocation to investments (ISA or GIA) is almost always the right call.
If you’re building towards £1m rather than managing one, the mechanics are simpler than they look. Time, consistency, and a globally diversified portfolio inside tax wrappers gets most people there in 20-35 years depending on contribution rate.
