How the loan calculator works
Enter the amount, the interest rate and the term. The calculator builds the full payment schedule for the Price system, where every payment is equal, and for the SAC system, where the principal repaid each month is constant and the payments shrink over time. Compare both to see how much interest you would pay.
Choose how your rate is quoted: per month, per year compounded (effective) or per year as a nominal APR divided by 12. Everything is calculated in your browser, so nothing you type leaves your device. Download the table as CSV to open in a spreadsheet.
- 1 Enter the loan amount, the rate and the term.
