There is no universally "better" mortgage: fixed gives peace of mind, variable bets on low rates and mixed seeks the best of both. What matters is understanding what you pay in each scenario and choosing based on how much you value stability versus potential savings.
The three options
Fixed-rate mortgage
The interest rate stays the same throughout the life of the loan. The monthly payment does not change whatever happens with the Euribor. Advantage: total predictability. Drawback: if rates drop, you do not benefit, and it usually starts from a slightly higher rate than the variable when signed.
Variable-rate mortgage
The interest is Euribor + a fixed margin (for example, Euribor + 0.8%). The payment is revised periodically (every 6 or 12 months): if Euribor rises, you pay more; if it falls, less. Advantage: if rates are low, you pay little. Drawback: uncertainty — your payment can rise.
Mixed-rate mortgage
An initial fixed-rate period (usually 5–15 years) and the rest variable. It seeks to combine the peace of mind of the early years with the potential of the variable later. It is the "middle" option many banks promote.
Euribor, nominal rate (TIN) and APR (TAE)
- Euribor: the reference index of variable mortgages in Europe. It fluctuates with monetary policy; it cannot be predicted with certainty.
- TIN (nominal interest rate): the "pure" interest of the loan.
- TAE (annual percentage rate / APR): includes TIN + fees + costs. It is the figure that really allows comparing offers, not the TIN alone.
A low TIN with lots of fees and bundled products can end up more expensive than a slightly higher TIN with no extras. Always look at the APR.
Quick comparison
| Fixed | Variable | Mixed | |
|---|---|---|---|
| Payment | Constant | Changes with Euribor | Fixed at first, then variable |
| Risk | None (predictable) | High (uncertainty) | Medium |
| If rates drop | You do not benefit | You pay less | Only in the variable period |
| Best for | Those who value stability | Those who tolerate risk / short term | Intermediate profile |
Bundled products and fees
Banks tend to offer a lower margin in exchange for bundled products: salary direct deposit, home and life insurance, cards, pension plans. They reduce the rate but have a cost: calculate whether the interest savings offset the spend on the products. Also review opening, early repayment and subrogation fees.
How to choose based on your profile
- You want to sleep soundly and have the same payment forever → fixed.
- Short term or you will repay early, and you tolerate variation → variable.
- You seek balance: peace of mind in the early years and then see → mixed.
- In all cases: compare several offers by APR and negotiate the bundled products.

Which is better, fixed or variable?
It depends on your profile. Fixed gives security (constant payment); variable can be cheaper if rates are low, but with risk of rising. Mixed is the middle ground.
What is the Euribor?
The reference index of variable mortgages in Europe. It rises or falls with monetary policy and determines how much you pay on a variable mortgage (Euribor + margin).
Why compare by APR (TAE) and not by nominal rate (TIN)?
Because APR includes fees and costs, not just the interest. Two mortgages with the same TIN can have very different APRs depending on their extras.
Is it worth taking out the insurance the bank requires?
Only if the savings on the margin offset the cost of the products. Do the math; sometimes a slightly higher rate without bundling is better.
