Future Value Calculator
Use this calculator to determine the future value of an investment which can include an initial deposit and a stream of periodic deposits.
How the future value calculator works
It compounds a lump sum and any ongoing monthly contributions forward at your expected rate of return, showing how much of the ending balance is your money versus growth.
Worked example: with present amount of $10,000, annual rate of return of 6.00% and years of 20, the future value calculator shows value in 20 years of $33,102.

The formula
Future value = present amount × (1 + r)ⁿ plus the compounded value of each contribution, where r is the periodic rate and n the number of periods.

Questions about the future value calculator
What is future value?
What a sum of money today, plus any planned contributions, will be worth at a future date once it has earned a given rate of return.
Does this account for inflation?
No — it shows nominal future dollars. To estimate buying power, lower your rate of return by the expected inflation rate.
How sensitive is the result to the rate?
Very. Over long horizons small rate differences compound into large gaps. Test a conservative and an optimistic rate to bracket the outcome.
Is the Future Value Calculator free to use?
Yes. Every calculator on FinCalculators is completely free, with no sign-up, login or paywall. You can run as many scenarios as you like.
How much will $10,000 be worth in 20 years?
At a 7% average annual return, $10,000 grows to about $38,700 in 20 years through compounding. At 5% it reaches roughly $26,500, and at 10% about $67,300 — the rate matters enormously over long horizons.
