Frequently asked questions
Are these financial calculators free?
Yes — every calculator is free with your account and runs in your browser. Nothing you enter is uploaded or saved.
How accurate are the results?
Each uses the standard published formula (loan amortization, compound interest, present/future value, and so on) and shows the method, so results match a bank or spreadsheet.
Which calculator should I use to buy a home?
Start with House Affordability to set a budget, Down Payment to plan cash, then the Mortgage and Amortization calculators for the payment and interest.
