How it works
This calculator runs a month-by-month simulation: each monthly contribution is added to the balance, and interest is applied at your chosen compounding frequency (the annual rate divided by the number of compounding periods). The chart shows your total balance in indigo and your cumulative contributions in gray -- the gap between them is the interest your money earned. All calculations happen entirely in your browser. Results are estimates and do not account for taxes, fees, or variable returns; this is not financial advice.
