Mortgage calculator: Simulate your monthly payment

How does the mortgage calculator work?

Use this free simulator to get a realistic estimate of your monthly payment, total interest, and loan amount in seconds. It works with fixed, variable, and mixed-rate mortgages and uses the French amortization system, which is used by almost all banks in Spain. You only need four pieces of information: the property price, your available savings, the loan term, and the interest rate.

How much do I need to save before applying for a mortgage?

This is one of the most frequently asked questions. The general rule is simple:
The bank will finance a maximum of 80 % of the property value.
You must contribute the remaining 20 % upfront.
In addition, you will have to cover the purchase and sale expenses: between 8 % and
the 13 % of the price according to the autonomous community (ITP or VAT + AJD,
notary, registry and administrative services).
In total, it is recommended to have between the 28 % and the 33 %
of the property price in own savings before applying for the mortgage.
Example: For a €200,000 home, you would need between
€56,000 and €66,000 in prior savings.
