Use this calculator for clean future-value checks when you want time-value growth without ongoing contributions.
Inputs
This topic also has a deeper guide and a printable reference pack, so you can move from the live answer into the method, assumptions, and worked examples without leaving the topic cluster.
These are the main values the calculator uses. Keep the units consistent and, where relevant, match the assumptions explained in the related guide.
Unit: GBP
Use the amount you have today or at the start of the projection.
Unit: %
Enter the annual growth rate assumption for the whole period.
Unit: years
Set the number of years the amount is allowed to grow.
Use this page when you already know the present amount, annual rate, and time period and want the ending value directly.
The main result is the projected future value. The supporting figure shows how much of that total is growth above the starting amount.
If 5,000 grows at 6% for 8 years, the result shows the total future value and the amount added by growth over the period.
This page applies the single annual rate you enter and does not add contributions, fees, taxes, or market variability.
This page is the cleaner time-value tool for a one-off starting amount. The Compound Interest page is better when you also want regular contributions and compounding frequency controls.
Discount a future amount back to today's terms using the annual rate and time period you enter.
Project compounded growth from a starting balance, contribution schedule, rate, and compounding frequency using only the values you enter.
Use the Simple Interest Calculator to work out simple interest from values you control yourself, without baked-in policy assumptions.
Use the CAGR Calculator to work out cagr from values you control yourself, without baked-in policy assumptions.
