How we calculate
Loan and mortgage payments use the standard fixed-payment amortization formula. Investment growth uses compounding at the stated rate. Debt payoff examples are month-by-month simulations with a fixed monthly budget. All rates are sample values for comparison, not current quotes or offers. Read our methodology and editorial policy.
