Frequently asked questions
How much will £10,000 be worth in 10 years?
It depends on the return you earn. If you save or invest at a steady annual rate, money grows through compound interest. For example, £10,000 at 5% a year compounded monthly would grow to about £16,470 after 10 years before tax. Inflation reduces purchasing power: the same pot might be “worth” less in today’s money if prices rise. Use the calculator above to plug in your amount, years, and rates.
How much is £100 a month for 20 years?
With no interest, £100 a month for 20 years is £24,000 paid in. With compound growth on each contribution, the final balance can be much higher depending on the rate. Enter £100 monthly and 20 years in this calculator and set an expected return to see the total.
What does “worth” mean — nominal or real?
Nominal value is the actual number of pounds in the future. “Real” or “in today’s money” adjusts for inflation so you can compare purchasing power. Both matter: nominal for your account balance, real for whether you can buy more or less than today.
What interest rate should I use?
For cash savings, use the AER on your account. For investments, people often use long-term average returns for illustration (e.g. mixed portfolios), but returns are not guaranteed. This tool is for illustration only.
Does this include tax?
No. Returns are shown gross. Use our Savings Interest Calculator for tax on non-ISA savings, or our ISA Calculator for tax-free growth inside an ISA.
