Mortgage Calculator

A mortgage is a long-term loan secured against property. The monthly payment you make to your bank consists of two components: principal (the repayment of the amount borrowed) and interest (the cost of borrowing). This calculator uses the French amortization method — the standard used in Spain and across most of Europe.

In the early years of your mortgage, the vast majority of each payment covers interest. As time passes, the balance of your loan decreases, meaning less interest accrues each month, and a larger proportion of your payment goes toward principal. The amortization table below the calculator illustrates this progression year by year.

To get the most accurate estimate, enter the full property price and your planned down payment. The calculator will determine your loan amount automatically and display your monthly payment alongside total interest paid over the life of the loan.
