How a mortgage payment is calculated

Most Spanish mortgages use French amortization: a constant payment while the rate stays fixed. Early payments are interest-heavy; later ones repay more principal.

Payment depends on remaining principal, interest rate, and months. An online calculator applies that formula instantly but usually omits insurance, fees, and variable-rate spreads.

Compare APR-style figures across bank offers, not only the simulated payment.

With a variable rate, the payment changes at each index review. Use calculators for scenarios, not as a contract.

Before signing, review the bank’s standardized information sheet and purchase costs.
