How the annuity payment works

With the most common loan type (annuity), the monthly payment stays the same for the whole term. Early on, most of it covers interest; as the term progresses, a growing share goes toward principal. That's why early extra repayments save disproportionately more interest.

Frequently asked questions

How is the monthly loan payment calculated?

Using the standard annuity formula, where the payment stays constant for the whole term and covers both interest and principal β€” interest dominates early on, and principal takes a growing share as the term progresses.

Does this calculator show the APR?

No β€” it uses the nominal annual interest rate you enter. The Annual Percentage Rate (APR/GPR) also folds in extra fees (processing, insurance, etc.) and is always somewhat higher than the nominal rate. Check the APR on the actual bank offer.

Why is the total amount paid higher than the loan amount?

Because it includes interest for the entire loan term. The longer the term, the more total interest accrues, even at a lower monthly payment.
