How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

Given a present value, future value, and time period, this calculator solves for the annual interest rate using the compound interest formula: r = (FV/PV)^(1/t) - 1.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.
