Euribor, Spread & Your Rate — Explained Simply
What actually sets your mortgage rate in Portugal: how Euribor and the bank's spread combine, and the difference between fixed, variable and mixed rates.
Your mortgage rate in Portugal isn’t one number a bank invents — it’s built from two parts. Understanding them helps you compare offers and know what’s actually negotiable.
Euribor: the part nobody controls
Euribor is the euro-area benchmark interest rate. It moves with the wider market, and most variable mortgages in Portugal are indexed to it (commonly the 6- or 12-month Euribor). When Euribor rises or falls, variable payments follow at each review.
Spread: the part you negotiate
The spread is the bank’s margin, added on top of Euribor:
Your variable rate = Euribor + the bank’s spread
The spread is where banks compete, and where a broker earns their keep — a lower spread means a cheaper loan for the entire term. It depends on your profile, the loan-to-value, and what else you bring to the bank.
Fixed, variable or mixed?
- Fixed — the rate stays the same for the whole loan. Predictable payments, usually priced a bit higher.
- Variable — Euribor + spread, so it moves over time. Often starts lower, with more risk.
- Mixed — fixed for the first years, then variable. Stability now, flexibility later.
There’s no universally “best” choice — it depends on your appetite for risk and how long you’ll keep the loan. Our interest rates page goes deeper, with current reference figures.
TAN vs TAEG
When comparing offers, look at the TAEG (the all-in annual cost, including fees and insurance), not just the TAN (the headline nominal rate). Two loans with the same TAN can cost very differently once everything is counted.
