Calculate the APR of a mortgage
Calculate the APR of your mortgage
This calculator will let you calculate the APR of a mortgage based on the amount of the loan, its nominal interest rate, repayment term, fees, and, if it were compulsory, the payment protection insurance premium.
You can make various calculations and compare the APR for each of them.

This calculator can be used for loans incurring fees and expenses which have to be included in the calculation of the annual percentage rate (APR) and which are paid when the loan is arranged and on a regular basis.
This calculator is based on the assumption that the loan is repaid in equal monthly instalments and that the proportion of the monthly payment corresponding to interest is calculated using the following formula:
(Outstanding capital x nominal annual rate) / 1200.
Calculations have been simplified as follows, so that the calculator can be used with in as many cases as possible:
 Customers pay all the loan assessment, evaluation and arrangement costs on the date the loan agreement is signed
 Instalments are paid on a monthly basis
 Every month of the year has the same number of days
 There are no payment holidays and the first payment is made exactly one month after the loan has been arranged
The instructions for calculate the annual percentage rate can be found in Anexo II of Ley 5/2019, de 15 de marzo, reguladora de los contratos de crédito inmobiliario.Abre en ventana nueva.
