Savings Calculator

Put in what you've saved already and what you can add each month, and this shows what you'd have at the end: the balance, how much of it is interest rather than your own money, and what that amount would actually buy once inflation is taken into account.

What you're putting in

Amount you have saved already (£)

Amount you'll add each month (£)

Either one on its own is fine. Leave a field at 0 if it doesn't apply to you.

Interest rate (% a year)

The rate your account pays, sometimes shown as AER. Your bank publishes it, and it can change at any time on an easy-access account.

What it will actually buy

Assumed inflation (% a year)

2.5% is a reasonable long-run assumption — it's close to the Bank of England's 2% target — but any single year can be well above or below it. Set it to 0 to ignore inflation entirely.

Your £16,198 would have the spending power of £12,654 in today's money. At 4% interest against 2.5% inflation you're growing your money in real terms, by about 1.5% a year.

Both numbers are real. The balance is what the bank will show you; today's money is what it would be worth at the shops. See Savings vs Inflation to explore this on its own.

Compare against another account

Another rate to compare (% a year)

Enter the rate on another account and we'll show what the difference is worth over your saving period. Switching accounts is usually the single easiest way to earn more.

Year by year

After	You paid in	Interest	Balance	In today's money
1 year	£2,200	£66	£2,266	£2,211
5 years	£7,000	£856	£7,856	£6,944
10 years	£13,000	£3,198	£16,198	£12,654

Interest is assumed to be added monthly and left in the account, with no withdrawals, no fees and the same rate throughout. A real easy-access rate can change at any time.

🔒 Calculated on your device; nothing is stored or sent. This tool is education, not financial advice.

This calculator needs JavaScript (it runs entirely on your device). The pen-and-paper version: your balance grows by the interest rate each year, and every monthly payment you add starts earning from the month you pay it in. The longer you leave it, the more of the final pot is interest rather than your own money. Remember that inflation works the other way, so a balance that grows more slowly than prices is losing buying power even as the number goes up.

Important information

Any growth rate here is an assumption, not a forecast, a promise, or a typical result. Where you have not changed it, the figure is our default rather than your choice, and you can change it. Investments can fall as well as rise, you may get back less than you put in, and past performance is not a guide to future performance.

We do not make personal recommendations. The tool shows you the result of a calculation based on the figures you enter. It does not tell you what you should do, and nothing it shows is presented as suitable for you or your circumstances.

The figures are estimates worked out by a computer program from the assumptions and information you enter. They are not a quote, an offer, or a statement of what you will actually pay or receive, and they will not reflect every part of your personal circumstances.
