Mortgage calculator Spain: estimate your monthly payment as a non-resident

By Veronica Vaccarezza, certified mortgage advisor · Updated September 29, 2026 · 3 min read

When you start looking at property in Spain, two questions come first: how much can I borrow, and what will it cost me each month? A mortgage calculator gives you a quick answer. For international buyers it is especially useful, because Spanish banks apply their own criteria to non-residents, and that changes how much they will finance.

In this guide I explain how to get the most out of a calculator, and what it will never tell you.

How much can a non-resident borrow in Spain?

As a guide, non-residents can usually finance up to 75% of the purchase price, depending on their profile, the bank and the property. Loan terms can usually run until you are 75, and in some cases until 80.

A quick example

  • Property price: €400,000
  • Loan at 70%: €280,000
  • Term: 25 years
  • Interest rate: 3%

Estimated monthly payment: around €1,328.

That figure is a good starting point. But whether a bank will actually lend you that amount depends on things the calculator cannot see.

What a mortgage calculator does

A mortgage calculator helps you estimate three things:

  • How much you can borrow, based on your income and existing commitments.
  • Your monthly payment, for different interest rates and terms.
  • The own funds you will need: for non-residents, around 30% of the price, plus 8–13% for taxes and buying costs depending on the province (at the lower end in the Canary Islands).

Using one early helps you search with realistic numbers and avoid applications that are bound to fail.

How to use it well

  1. Start with the price. Enter the price of the properties you are looking at. It helps you focus your search on what you can really afford.
  2. Play with rates and terms. Compare fixed, variable and mixed rates and different terms, and see how each one changes your monthly payment.
  3. Check your affordability. Include your income and your current debts. Banks look closely at how much of your income goes to repayments.
  4. Think ahead. Try different scenarios, such as a rate rise or a shorter term, so there are no surprises later.
  5. Then talk to an advisor. A calculator gives you an estimate; an advisor tells you which bank will actually say yes, and on what terms.

What a calculator does not show

A calculator is a useful first step, but it does not include:

  • Each bank’s approval criteria. Every lender has its own rules for non-residents.
  • How your income is structured. Foreign income, self-employment or company income are assessed differently.
  • Currency risk. If you earn in another currency, exchange rates affect your real payment.
  • The valuation. Banks lend on the valued price, which may be lower than the purchase price.
  • Linked products. Some banks improve the rate if you take insurance or other products.

That is why it pays to go over the calculator’s numbers with an advisor.

Common mistakes of international buyers

  • Assuming you can borrow the same as at home. Spanish banks are usually more conservative with non-residents.
  • Forgetting taxes and costs. They add 8–13% to the price and must come from your own funds.
  • Using unrealistic interest rates. Very low rates make the payments look better than they will be.
  • Reserving a property before checking the mortgage. Get your profile pre-approved first, so you know your real personal investment before you commit.

These mistakes cause delays, rejected applications and, sometimes, lost deposits.

In short

A calculator gives you a first figure to start your search with. What decides the mortgage is your profile and the bank you choose. If you want to know how much you can really borrow, tell me about your plans and I will give you a first view of your options, at no cost to you and with no obligation.

Frequently asked questions

Why use a mortgage calculator?

It helps you estimate how much you can borrow, your monthly payment and the own funds you need, so you understand what you can afford before speaking to the banks.

How accurate is it?

It gives estimates based on general assumptions. The final conditions depend on the bank, the valuation of the property and your financial profile.

Does it include all the costs?

Usually not. Taxes, notary, land registry and legal fees add around 8–13% to the price, depending on the province.
