How it is calculated

The monthly payment uses the annuity formula: payment = amount × monthlyRate × (1+monthlyRate)^n ÷ ((1+monthlyRate)^n − 1), where monthlyRate is the annual rate ÷ 12 ÷ 100 and n is the term in months. This is the standard equal-payment formula banks use.

Total paid = payment × term in months. Overpayment = total paid − loan amount — how much the loan costs above the principal.

The calculation doesn't include possible bank fees (origination, account servicing, insurance) — if your offer has them, add them to the overpayment separately.
