Future Value Calculator
A lump sum plus contributions, in nominal and real terms.
Work out Future Value. A lump sum plus contributions, in nominal and real terms. Handles the case where the obvious answer is wrong.
Optional — shows the value in today's money.
Future value
$19,318.14
$6,318.14 of that is growth
Contributions are treated as arriving at the end of each period, which is the ordinary annuity convention. Paying at the start instead earns one extra period of interest on every payment. The nominal 7.00% compounds to an effective 7.229% at this frequency.
How the Future Value Calculator works
A starting balance plus regular contributions, compounded at your chosen frequency. The inflation field is the one worth using: nominal growth flatters a long horizon, and the real figure is the one that tells you what the money will actually buy.

Frequently asked questions
What is the future value formula?
FV = PV(1+r)ⁿ for a lump sum, plus PMT × ((1+r)ⁿ − 1)/r for regular contributions. Both are computed here and added.
Why does contribution timing matter?
Paying at the start of each period rather than the end earns one extra period of interest on every payment. This page uses the end-of-period convention, which is standard.
What is the effective annual rate?
What the nominal rate actually delivers once compounding is counted. 6% compounded monthly is 6.17% effective, which is the figure to compare between products.
Should I adjust for inflation?
For anything over a few years, yes. At 3% inflation, money halves in purchasing power roughly every 23 years — so a large nominal figure decades out can be a modest real one.
