How Future Value is Calculated
FV of lump sum: FV = PV × (1 + r/n)n×t — your initial deposit grows exponentially via compound interest.
FV of periodic contributions (ordinary annuity): FV = PMT × [((1 + r/n)n×t − 1) / (r/n)]
Annuity due (beginning of period) multiplies by (1 + r/n) since each payment compounds one extra period.
r = annual nominal rate, n = compounding periods/year, t = years, PMT = periodic contribution. Mismatched compounding and contribution frequencies are handled via an effective per-contribution rate.
The future value calculator shows exactly how a lump sum investment grows with compound interest over time, including the powerful effect of regular periodic contributions. Enter your initial deposit, annual rate, time horizon, and optional recurring contributions to instantly see your projected balance — broken down into principal, contributions, and interest earned.
Future value (FV) is what a sum of money today will be worth at a specific date in the future, given a rate of return. It quantifies the time value of money — a dollar invested today is worth more than a dollar received in the future because it can earn interest in the interim.
More frequent compounding means interest is calculated and added to your balance more often, so subsequent interest is earned on a slightly larger base. Monthly compounding yields more than annual compounding at the same nominal rate. The difference grows more pronounced over longer time horizons.
An ordinary annuity (end of period) makes each contribution at the end of a period, so it earns one fewer compounding period than an annuity due. An annuity due (beginning of period) contributes at the start, giving each payment one extra compounding period — resulting in a slightly higher future value.
Yes. Enter your current savings as the present value, your expected annual return, your target retirement horizon in years, and your planned monthly contribution. The year-by-year schedule lets you track milestone balances and see how much of your final balance comes from growth versus your own contributions.
