This installment calculator works out the monthly payment, credit cost and final total price of a hire-purchase from the purchase price, down payment, interest rate and term. It lets you see, before you sign, what paying on credit actually costs in euros.

How the calculator works and what it’s for

How the installment is built

First the down payment is subtracted from the purchase price to give the financed amount. That amount is spread over the term, with interest added on top, to form the monthly payment.

The credit cost is the sum of all payments minus the financed principal. The total price is the down payment plus every installment you pay.

What you enter and what you get

Enter the purchase price, the down payment, the annual interest rate and the term in months. The result shows the financed amount, the monthly payment, the credit cost and the final total price.

A larger down payment or a shorter term reduces interest costs. A longer term lightens the monthly payment but raises the total price.

Who it is for

The calculator is handy when you are considering buying an appliance, furniture, a car or electronics on installments and want to compare it against paying upfront or against different financing offers.

Good to know

The real APR often also includes opening and account fees, which this calculator does not account for. Always compare offers using the stated annual percentage rate.
