How much will £750 a month be worth in 30 years?
£750 a month for 30 years at different returns
The return you actually get depends on where the money is kept. A savings account usually pays less than a stock market investment, but it carries much less risk of falling in value.
The figures assume you pay in at the end of every month and the return is compounded monthly. They ignore charges, tax and inflation, so treat them as a guide.

How the pot grows year by year (5% a year)
Growth speeds up the longer you save, because you earn returns on earlier returns. In the first years most of the pot is your own money; later the growth overtakes what you paid in.
| Year | Paid in so far | Value at 5% |
|---|---|---|
| 1 | £9,000 | £9,204 |
| 5 | £45,000 | £50,860 |
| 10 | £90,000 | £115,772 |
| 15 | £135,000 | £198,618 |
| 20 | £180,000 | £304,353 |
| 25 | £225,000 | £439,301 |
| 30 | £270,000 | £611,532 |

| £800 a month | £288,000 | £652,301 | +£40,769 |

What it is worth in today's money
Prices rise over time, so a future pot buys less than the same amount today. If inflation averages 2% a year, the £611,532 at 5% would buy what about £337,609 buys today. At 5% a year, growth reaches half of what you have paid in by about year 16.

Why starting early matters
If you waited 5 years and saved £750 a month for only 25 years at 6%, you would end with about £507,217 instead of £730,885. Those 5 years cost you roughly £223,668, even though you would have paid in only £45,000 less.
A rough guide is the rule of 72: divide 72 by the annual return to estimate how many years it takes money to double. At 6% that is about 12 years.
Where could you keep the money?
Common choices include a Stocks and Shares ISA, a cash ISA or a pension. Savings and investments held in an ISA are free of UK income tax and capital gains tax. Outside an ISA, interest above your Personal Savings Allowance and gains above the annual exempt amount can be taxed.
Money you may need within a few years belongs in cash savings. Money you will not need for ten years or more can take more investment risk, but it can fall in value as well as rise.
