Compare a fixed monthly repayment example
Enter the borrowed principal, a fixed nominal annual interest percentage and the number of monthly payments. The calculator divides the annual rate by twelve and uses equal period-end payments to amortize the principal. The report includes the monthly payment, total interest, total amount repaid and a payment-by-payment schedule. A zero interest rate is handled as an even division of principal across the selected term.
Treat the result as an illustration
The schedule assumes the same monthly rate for the entire term and no extra repayments. It excludes origination fees, insurance, taxes, late charges, variable-rate resets and lender-specific day-count or rounding conventions. A quoted APR can include costs beyond the nominal interest rate expected by this formula. Amounts are displayed to two decimals, while internal calculations retain more precision. Use the lender’s official disclosures and schedule when making a borrowing decision.
