28 Days Richer – Day 20: Compound Interest

Day 20 of 28 Days Richer

One thing each day that puts money in your pocket and takes 5 minutes or less.

Einstein called compound interest “the eighth wonder of the world” – here’s why.

The Numbers That Change Everything

£200 per month from age 25 to 65 becomes roughly £290,000*.

£200 per month from age 40 to 65 becomes roughly £118,000*.

Same monthly amount, same rate of return, but a £172,000 difference – all because of starting 15 years earlier.

*Based on an illustrative example of 5% annual returns.

Why It Works

Your money earns returns, those returns earn returns, and those returns on returns earn returns.

It snowballs.

In year one you’ve got what you put in plus a bit, but by year thirty most of your pot is growth rather than contributions.

*Based on historical average market returns of 8% annually

The Early Bird Example

If you invest £1,000 per year from age 18 to 28 and then stop completely (never adding another penny), while someone else starts at 28 and invests £1,000 per year for 35 years straight, at 65 you end up with more – despite investing for just 10 years versus 35.

That’s the power of starting early.

Today’s 5-Minute Action

Open a compound interest calculator online, plug in your age and a realistic monthly amount, and see what 20, 30, or 40 years of growth looks like.

The numbers are surprising and often really motivating.

The Point

Time beats timing, and starting now with small amounts beats waiting until you can afford “proper” investments.

Even £50 per month starting today outperforms £200 per month starting in ten years – the maths is clear.
