About this calculator

Future Value Calculator runs entirely in your browser. Enter your numbers and the answer updates as you type — nothing is uploaded, there is no sign-up, and it keeps working offline once the page has loaded.

Finance calculators turn rates, terms, and balances into the numbers that matter: a monthly payment, the interest you will pay, or what a sum grows to over time. They are estimates for planning, not financial advice.
