How it is calculated
The calculation uses the annuity payment formula — an equal payment for the whole loan term. Total payments = payment × number of months, overpayment = total payments − loan amount.
Overpayment as a percentage of the loan amount is a handy way to compare offers with different terms and rates: the longer the term at the same rate, the more interest accumulates, even if the monthly payment is smaller.
The calculation assumes a pure annuity schedule with no early repayments or extra fees. A differentiated schedule produces a smaller overpayment — compare both schedules directly with the separate payment schemes comparison calculator.
