Portugal Mortgage Calculator 2026

This free calculator estimates your monthly mortgage payment in Portugal based on the property price, your deposit, the loan term and the interest rate. It also computes the main purchase costs — IMT (property transfer tax), stamp duty on the purchase and on the loan — so you know the real budget before you make an offer.

Once you have your estimate, you can send it to our team in one click. As a credit intermediary registered with Banco de Portugal, we compare proposals from the leading Portuguese banks and negotiate on your behalf — at no cost to you.

Portuguese banks offer variable rates indexed to Euribor, fixed rates, and mixed rates that combine an initial fixed period with a variable phase. As a guide, mixed rates with a 2-year fixed period start around 2.45%, 5-year fixed periods around 2.75%, and full fixed rates around 3.45%, depending on your profile, the loan-to-value ratio and the bank.

Rates are indicative and change with the market and each bank's risk assessment. The simulator above uses these reference rates so you can compare scenarios side by side.

Banks in Portugal generally lend up to 80–90% of the property value for residents and up to 60–80% for non-residents. Your borrowing capacity also depends on your debt-to-income ratio (taxa de esforço): from 2026, Banco de Portugal recommends it stays below 45% of your net income, including the new mortgage.

Use the calculator to test different deposits and terms, then read our step-by-step guide to getting a mortgage in Portugal or browse the blog for detailed guides on rates, taxes and buying as a foreigner.

On top of the property price, buyers pay IMT (a progressive transfer tax from 0% to 7.5% depending on price and residency status), 0.8% stamp duty on the purchase price, and 0.6% stamp duty on the loan amount. Buyers aged 35 or under purchasing their first home may benefit from the IMT Jovem exemption on properties up to €330,539, with partial relief up to €660,982. The calculator includes all of these automatically.

Non-residents buying in Portugal usually need a larger deposit — most banks finance 60–80% of the purchase price (or the valuation, whichever is lower) — and since 2026 non-residents pay a flat 7.5% IMT on residential purchases, whatever the value or use. Set your residency status in the simulator and the monthly payment, IMT and total cash needed are recalculated for you.

For the full picture — documents, timelines, age limits and pre-approval — read our complete guide to mortgages in Portugal for non-residents.

The estimate covers the monthly capital and interest payment, IMT, stamp duty on the purchase and on the loan, and the deposit you need to have available. Bank arrangement and valuation fees, notary and registration costs, and life and home insurance premiums vary by lender and by property, so they are quoted individually once we have bank offers on the table.

Budget around €2,000 on average for bank and notary costs, often more for non-residents.

Is the Portugal mortgage calculator free? Yes. It is free to use, no registration required, and our brokerage service is also free for you — banks pay our fee.
