Every euro a lender’s advertised rate doesn’t show you: mandatory insurance, transfer & stamp taxes, ongoing property tax, and whether your age even qualifies you for the term you want. Every field below says exactly when that cost hits — once, monthly, or every year.
FOR AMERICAN & EXPAT BUYERS
Portugal Mortgage — True Cost Calculator
1. Property & Financing
Purchase details and how much you're borrowing.
€
Non-residents typically need to put between 30% and 40% down; residents can often put as little as 10%.
This changes the transfer tax (IMT) you owe — secondary homes are taxed from the first euro, primary homes get an exemption up to €106,346.
2. Your Loan
Most Portuguese mortgages are referred to as "Mixed Rate," in that they are fixed for the first few years, and then shift to a variable rate for the remainder of the term. (Want an all-fixed or all-variable loan instead? Set the fixed years to your full term, or to 0.)
Your payment recalculates the day the rate switches — the panel on the right shows both amounts.
Portuguese banks require the loan to be fully paid off by a certain age – commonly 70, sometimes 75 – which limits the length of your loan. Always confirm this with your lender.
3. Insurance
Portuguese banks require both policies to release a mortgage — they are not optional add-ons.
Typical bank-tied life insurance for a couple runs roughly €1,000–1,500/yr; independent insurers can often beat that by 30–60% for the same cover. Home insurance for a standard apartment typically runs €200–450/yr.
Your actual premium depends on your age and health. Insurers ask about things like heart disease, cancer history, and diabetes — this can raise the price, require a medical exam, or in some cases lead to a decline from a specific insurer. None of this affects whether you can get the mortgage itself, only the cost and approval of the life insurance policy the bank requires. Get a real quote from an insurance broker by providing your specific health details, rather than relying on the number above.
4. Taxes & Closing Costs
Most buyers have never heard of these — pick the option closest to your situation, or leave the defaults.
This rate is set by each municipality. It ranges from 0.3% to 0.45%, although the vast majority are right around 0.3% which is the number we use here to estimate your IMI.
Property Transfer Tax – IMT (one-time fee paid at the time of deed signing)
This amount is based on the purchase price (or VPT, whichever is higher), your age, whether this is your primary residence, and your tax residency status.
As of 2026, non-residents pay a flat 7.5% of the purchase price (or VPT, whichever is higher) instead of the standard sliding scale below.
Full IMT exemption on primary homes up to €330,539; partial exemption on the portion up to €330,539 for homes priced up to €660,982. Doesn't apply to non-residents or secondary homes.

Wealth Surcharge – AIMI (paid every year you own it, on top of IMI)
An additional annual tax on properties with a tax value over €600,000 for a single buyer, or €1,200,000 for those filing jointly.
—
Stamp Tax – Purchase & Mortgage (one-time, paid at the deed signing)
A fixed 0.8% of the purchase price, plus a fixed 0.6% of the loan amount (if any).
