How does the calculator work?

Property value

Enter the total price of the property you want to buy. This will be the reference value to calculate the loan and LTV.

Down payment

Amount you will pay upfront. Banks normally finance up to 80% of the appraisal value, so you will need at least a 20% down payment.

Interest rate

In December 2025, with Euribor at 2.22%: Fixed rate from 2.15% to 2.69%. Variable rate: Euribor + 0.49% to +0.85%. Use 2.50% for fixed or 2.71% for variable as reference.

Amortization term

Number of years in which you will repay the loan. The most common terms are 20, 25 or 30 years. Longer term means lower monthly payment but more total interest.

Important tips

  • •The monthly payment should not exceed 30-35% of your net monthly income.
  • •Remember that in addition to the payment, you will have deed, notary, registry and tax expenses (approx. 10% of the price).
  • •A shorter term means higher monthly payment but less total interest. Balance according to your payment capacity.
  • •This is an estimate. Real conditions will depend on your credit profile and the banking institution.
