Mortgage Payment Simulator

With this simulator you can calculate in seconds your monthly payment, taxes and costs of buying a home. Compare different scenarios (price, term, interest rate) before talking to any bank so you arrive at the negotiation prepared.

Banks usually finance up to 80% of the purchase or appraised value (whichever is lower), so you'll normally need to have the remaining 20% available, plus the costs associated with the purchase.

In practice, it's advisable to have savings equivalent to 25%–30% of the property price to cover the down payment and the taxes or formalization costs.

When buying a second-hand home, the main tax is the Property Transfer Tax (ITP), whose general rate varies by autonomous region:

The rates shown are indicative and may vary depending on the property value or the buyer's circumstances. There are reductions and lower rates for certain groups, such as young people, large families or people with disabilities. When buying a new home, VAT (10%) and the Stamp Duty (AJD) apply instead of ITP.

The payment is calculated using the French amortization system, the most common in Spain: you pay a constant amount each month and, at the beginning, interest weighs more than principal. If the mortgage is variable, the payment is revised according to Euribor plus the agreed spread. Here is an indicative payment simulation for a 150,000 € loan over 25 years:

Indicative figures. The actual payment will depend on the rate each lender offers you. As of June 2026, the 12-month Euribor is around 2.8%.

No. They are indicative and based on the data you provide and average market conditions. Final approval and specific terms will depend on each lender's analysis of your profile: income, credit history, employment stability and other factors.

No. The simulation is completely free and involves no commitment. You can simulate as many scenarios as you want —changing price, term or interest rate— without registering, without providing documentation and without affecting your credit profile.

Yes. The connection is made through Open Banking, the regulated European standard that lets you share your banking data encrypted and only with your consent. We never access your credentials and cannot move money from your account: lenders only look at the information needed to offer you better terms.

The process typically includes: simulation and offer comparison, formal application with documentation (ID, payslips, tax return), lender risk analysis, official property appraisal, credit proposal with terms, and signing before a notary with registration in the Property Registry. From application to signing usually takes 4 to 8 weeks.

With a fixed rate you pay the same payment regardless of Euribor changes, giving you certainty though the initial rate is usually higher. With a variable rate, your payment adjusts periodically based on Euribor plus a bank spread. It may be cheaper initially but you assume the risk of rising rates.
