Calculation methodology

How this estimate is calculated

  1. 1. Monthly rate: the annual percentage rate is divided by 100 and then by 12. This is a simplified fixed-rate installment-loan model, not a Canadian mortgage-rate conversion.
  2. 2. Monthly interest: interest equals the opening balance for that period multiplied by the monthly rate. The regular payment is then applied to interest first and the remainder reduces principal.
  3. 3. Extra payments: the one-time extra amount reduces the balance before month one. The extra monthly amount is added to every later regular payment.
  4. 4. Final payment: when the scheduled payment is more than the balance plus that month's interest, the model uses only the amount needed to bring the balance to zero.
  5. 5. Rounding: the simulation keeps full JavaScript numeric precision from period to period. Currency is rounded to the nearest cent only when displayed. Lenders may round at different stages.

How the payoff month is estimated

The calculator starts with the current calendar month and adds the number of simulated monthly payment periods. A partial period would be rounded up to the next payment month. The result is deliberately shown as a month and year, not an exact due date.

Your lender's payment date, posting time, daily-interest treatment, and processing rules may produce a different payoff date.

What this estimate does not include

The calculation does not include lender fees, prepayment penalties, variable interest rates, skipped or irregular payments, insurance, taxes, daily-interest posting, payment processing rules, or mortgage-specific terms.

Review your loan agreement and confirm payment instructions with your lender before sending extra money. This tool provides informational estimates, not financial, tax, or legal advice. The Financial Consumer Agency of Canada personal-loan guide notes that extra-payment permissions and early-payoff fees may differ by lender and agreement.

Is this debt a Canadian mortgage?

This loan tool uses simplified monthly interest. For a fixed-rate mortgage estimate that converts a nominal annual rate using semi-annual compounding and supports several regular payment frequencies, use the Mortgage Prepayment Calculator Canada.
