About Future Value Calculator (FV)
Future value is the foundational equation of finance: what a sum today becomes when compounding works on it. $10,000 at 7% compounded annually doubles to roughly $19,700 in ten years — and the formula's exponent is why every other finance answer (retirement corpora, loan balances, bond prices) is some rearrangement of this one line. The compounding-frequency dropdown teaches its own lesson: moving from annual to monthly compounding at 7% lifts the ten-year result by only about $330 on $10,000. Frequency matters far less than rate and time — a marketing emphasis on 'daily compounding' is usually decoration on an unremarkable rate. Compare the effective annual yield, not the compounding adjective. Use FV prospectively and skeptically: project a windfall before deciding to spend it (the $10,000 vacation actually costs its $19,700 future self), sanity-check a sales projection someone shows you, or convert 'small' recurring fees into their future-value cost. The formula is exact; the rate you feed it is the assumption that deserves scrutiny.

Frequently asked questions
What's the difference between future value and compound interest?+
Same engine, different focal point. Compound interest reports the growth (FV minus the principal); future value reports the destination (principal plus growth). This calculator shows both — the headline is the destination, the 'total growth' line is the interest. Loan ads quote interest to look small; investment ads quote future value to look big. Knowing they're one formula inoculates you against both framings.
How do I pick the rate for a projection?+
Match it to the asset: ~4–5% for high-grade bonds or today's savings yields, 6–8% for diversified stocks after fees, your actual quoted APY for deposits. The honest move is to run the calculation three times — pessimistic, expected, optimistic — and plan around the pessimistic one. A single-point projection at an optimistic rate is how retirement plans quietly fail.
Does this account for inflation?+
No — this is nominal future value, the number that will appear on the statement. To see purchasing power, subtract expected inflation from the rate first: at 7% nominal with 3% inflation, run the calculation at ~3.9% ((1.07/1.03)−1). The nominal answer funds the account; the real answer funds your life. For goal-planning, the real rate is the one that matters.
Why does compounding frequency barely change the answer?+
Because the limit is tight: the gap between annual and continuous compounding at rate r is bounded by e^r vs (1+r) — at 7% that's 7.25% vs 7.00% effective. Rate and time enter the exponent's base and power respectively; frequency only nibbles at the base. Doubling your rate or your horizon transforms the result; daily-vs-monthly compounding changes lunch money.
