Each tool uses the same future value and compound interest formulas a finance textbook would. The explainer on every page shows the formula so you can verify the result by hand.
Calculations happen in your browser. We do not store the amounts you type or ask you to create an account to see an answer.
Returns are assumptions, not promises. Every projection here is an estimate for planning. For investor basics we point to the SEC at investor.gov.
Yes. Every calculator on the site is free, needs no account, and runs entirely in your browser. There is no paywall and no limit on how many times you can run a calculation.
The math is exact for the inputs you give. The accuracy of the projection depends on your assumptions. A real portfolio rarely earns the same return every year, so treat the future value as a planning estimate rather than a guarantee.
No. These tools are for education and planning only. They are not financial, tax, or investment advice. For decisions about your own money, speak with a licensed professional and review investor resources at investor.gov.
Start with the Investment Calculator if you contribute regularly and want a future value. Use the Compound Interest Calculator when you want to see how a single balance grows at a set rate and compounding frequency.
