It's one of the most important decisions you'll make when buying a property in Luxembourg: the type of interest rate you choose for your loan. Fixed, variable, adjustable... Your choice will have a decisive impact on the cost of your loan, and on the financial risks associated with your purchase. We'll explain everything.
In a nutshell:
- Luxembourg banks offer three types of rates: fixed rate which is constant over the entire duration, variable rate which is based on Euribor with fluctuating monthly payments, and the variable rate (which is fixed for a given period and then variable).
- Luxembourg buyers now prefer stability after variable rates soar in 2022 which forced many owners to sell their property as a matter of urgency.
- Experts now recommend a 3-5 year variable rate. and then renegotiate a fixed rate when rates fall.

What types of rate are available in Luxembourg?
In most European countries, the choice is fairly standard: buyers generally opt for a fixed rate for the entire term of the loan. Few banks offer other formulas.
But in Luxembourg, things are a bit different. When simulating a loan, a Luxembourg bank will generally offer you 3 types of rate:
- A fixed rate : This is a rate that remains unchanged throughout the repayment period of your loan. Generally, this is the option with the highest rate (because it is also the most secure for the buyer).
- A variable rate : are the current market rates (Euribor) to which the bank adds its margin. This rate therefore changes regularly according to the reference Euribor rate (3 months, 6 months, 12 months). With this type of rate, your monthly repayments change frequently. It's a risky rate, but it's also generally lower than a fixed rate.
- A variable rate : this is a fixed rate agreed for a given period. A "5-year variable rate" means that the rate chosen does not change for 5 years. It then automatically switches to a variable rate, depending on market rates.
Then it's up to each buyer to choose their preferred type of rate according to their means and sensitivity to risk.
What type of rate is recommended for 2026?
For a long time, the variable rate was one of the most popular rates in Luxembourg. Quite simply because the market was stable and the rate was lower than the fixed rate. Some Luxembourgers even had a loan with a variable rate of less than 1%!
But everything changed when the markets took off in 2022: the variable rate skyrocketed. Many homeowners had to sell their property because they could no longer afford the new monthly repayments. That's why no Luxembourg bank will now offer a "capped variable rate" (a rate that cannot exceed a certain threshold - this was common practice before 2022).
Since this episode, Luxembourg buyers have preferred to opt for more stable and secure solutions. There are two schools of thought:
Opt for a fixed rate: the safe bet
With a fixed-rate loan, all the parameters of your loan are defined at the time of signing:
- The nominal interest rate remains constant over the entire duration
- The amount of the monthly instalments never varies (unless voluntarily modulated)
- Repayment period is fixed in advance
- Total cost of credit is perfectly known and calculable
This predictability makes the fixed rate one of the benchmark choices for those buying in 2026. Luxembourg banks generally offer fixed rates for terms ranging from 5 to 35 years. However, 30-year formulas are the most popular.
Choosing a variable rate: the choice of future optimisation
Most experts and brokers now recommend a hybrid structure. As we are in a market that is stabilising, with rates gradually falling, the advice today is to :
- Choose a revisable fixed rate over 3 to 5 years
- Renegotiate a fixed rate when rates are lower in 3 to 5 years' time
Of course, these are just projections: rates could just as easily rise and you could end up paying more. It all depends on your reading of the economic situation, your intuition and your sensitivity to risk.

FAQ: Frequently Asked Questions
What kind of rates do Luxembourg banks offer?
Luxembourg banks offer three types of rate for home loans: a fixed rate that remains constant throughout the term of the loan, a variable rate based on Euribor that changes regularly, and a variable rate that is fixed for a given period and then switches to variable.
What type of rate should I choose for a mortgage in Luxembourg in %currentyear%?
In %currentyear%, the experts recommend a fixed rate or an adjustable rate over 3-5 years in Luxembourg rather than a pure variable rate. Since interest rates soared in 2022, buyers in Luxembourg have been looking for security after seeing many owners forced to sell their property. The fixed rate offers total predictability of monthly repayments and the total cost of borrowing.
What is a variable rate in Luxembourg?
A variable rate in Luxembourg is a fixed rate for a set period that automatically switches to a variable rate depending on market conditions. For example, a "5-year variable rate" remains constant for 5 years and then follows the trend of Euribor. This formula allows you to benefit temporarily from the stability of the fixed rate before taking advantage of any future reductions.
Why are variable rates risky in Luxembourg?
The variable rate in Luxembourg is risky because it follows Euribor fluctuations and can explode rapidly, as it did in 2022. Many Luxembourg homeowners have had to sell their property because they could no longer afford the new monthly repayments following the surge in interest rates.
How does a fixed rate work in Luxembourg?
A fixed rate in Luxembourg guarantees a constant interest rate, fixed monthly repayments and a repayment period defined when the loan is signed. This formula gives you a clear idea of the total cost of your credit over the entire term..
What is the recommended term for a fixed rate in Luxembourg?
In Luxembourg, Fixed-rate terms vary from 5 to 35 years, but 30-year plans are the most popular with Luxembourg borrowers. This term offers a good balance between affordable monthly payments and the total cost of borrowing. Luxembourg banks offer this standard term, which is in line with local property market practices.
