How these calculators work

Every calculator runs in your browser: nothing you type is sent to us or stored on a server. All of them use the same tested amortization code, so a payment in one tool matches the others. Rates and costs are numbers you enter, and each page lists its assumptions and formula. Results update as you type, the address bar keeps your inputs so a shared link reopens the same numbers, and every result can be copied or printed.
