The time value of money

A dollar today is worth more than a dollar tomorrow, because it can grow. Future value tells you what money becomes after growing at a given rate — the foundation of every savings, investing, and retirement projection.

FV = PV × (1+r)ⁿ + PMT × ((1+r)ⁿ − 1) ÷ r

Quick FAQ

Future value vs present value?

Future value grows today's money forward; present value discounts a future sum back to today. They're two sides of the same time-value-of-money coin.

What rate should I use?

Match it to where the money sits — a savings rate for cash, a long-run market average for diversified investments. Lower rates give a more conservative estimate.
