Instalment credit

The monthly payment is not the price of the loan. A smaller payment over a longer term usually means more total interest when the rate is positive.

In more detail

Look at amount, rate, fees and term together. The same sum over more months typically lowers the payment and raises total interest. An instalment purchase or buy-now-pay-later follows the same logic once interest is charged on the instalments.

Background

With a fixed-rate loan paid in regular instalments, the payment stays constant; the interest share falls and principal repayment rises. A large final payment, variable rates and extra fees change the picture and are not always in the advertised instalment. In some places you can withdraw from the contract within a set time. The deadline and what it covers are local law, not a Finmon rule. The loan calculator is a model, not an offer or a refinancing recommendation.

An example

The same loan amount in the calculator over 36 and 72 months at the same positive rate: the monthly payment falls, total interest rises.

A common misconception

A small monthly payment means cheap credit.

The payment hides the term. Longer at a positive rate typically means more total interest.
