How it is calculated
Future value = sum today × (1 + annual return ÷ 100) ^ number of years. It's the basic compound interest formula for a single lump sum with annual compounding — what today's deposit grows into after N years at a constant rate of return.
The growth here is non-linear: the return applies not just to the original sum but also to the interest already accumulated in prior years, so the dollar gain gets bigger every year even though the rate stays the same. That's the compounding effect.
This calculation is the simplest case: a single sum, compounded once a year. For a different compounding frequency (monthly, quarterly), use the compound interest calculator. For the reverse question — how much to invest today to reach a target sum in the future — that's the present value calculator.
