Portugal mortgage calculator 2026

Yes. Portuguese banks lend to foreign buyers, resident or not, under the same Bank of Portugal rules. Banks are usually more cautious with non-residents: they tend to lend a smaller share of the value and ask for more documents, such as proof of income, recent tax returns and bank statements from your home country.

You will need a Portuguese tax number (NIF) and, in practice, a Portuguese bank account for the monthly payments.

Bank of Portugal rules cap the loan at 90% of the value for your permanent home and 80% for any other home. The value is the lower of the price and the bank's valuation: if the valuation comes in below the price, you need a larger deposit.

Banks usually lend non-residents less, often 60% to 70%. On top of the deposit you need cash for IMT, stamp duty and the deed: see the costs of buying.

The bank divides the payments on all your loans by the household's net income (the debt-to-income ratio, taxa de esforço). Since 1 August 2026 the Bank of Portugal recommends that it stays under 45%, and each bank can grant only 10% of its loans above that.

For a variable rate, or the variable part of a mixed rate, the bank tests the ratio at a higher rate than the one in the contract: plus 0.5% for terms up to 5 years, plus 1% up to 10 years and plus 1.5% above that. The calculator does the same when you enter your income.

Variable

Euribor plus the bank's spread. The payment follows Euribor, up or down, at each review.

Fixed

The same rate for the whole loan. It protects you from rises, but usually starts higher, and early repayment costs more.

Mixed

A fixed rate for the first years and a variable rate after. To estimate it, use the fixed rate in the offer for the first payment and the variable option for an idea of the payment afterwards.

The Euribor term is also the gap between payment reviews. With the 12-month Euribor the payment changes once a year; with the 3-month Euribor, four times a year. For October 2026 the averages were 2.635%, 2.975% and 3.239%.

Between reviews the payment stays the same even if Euribor moves. At each review the bank adds the spread to the previous month's average and recalculates the payment on the balance and the remaining term.

40 years if you are 35 or under, and 35 years above that age. With two borrowers, the older one's age counts. A longer term lowers the payment but adds a lot of interest: compare 30 and 40 years for the same amount in the calculator.

Life and home insurance, the bank's fees and the 0.6% stamp duty on the loan amount, which are paid separately. That is why the APRC (TAEG) in the bank's offer is always higher than the TAN. To compare banks, use the APRC on each bank's standard information sheet (FINE).

Interest on a loan for a home you live in, permanent or second, is exempt from stamp duty. On a home to let it pays 4%, and the calculator adds it when you choose that option.
