Finance Calculators
Fifteen free calculators for the money decisions Americans make most: buying a home, comparing a salary, taking a loan, paying off a card, and planning retirement. Every calculator runs in your browser, shows its working, and explains the result in plain English — no sign-up, no personal data, no uploads.
Start with the mortgage calculator if you are house hunting, the affordability calculator before you talk to a lender, and the retirement calculator if you want to know whether you are on track. The tools link to each other, so a mortgage question can lead naturally to an affordability check, and a loan question to a payoff plan.
