Fixed mortgage interest rates: everything you need to know

Buying a home in the Netherlands comes with an important decision — choosing between a fixed or variable mortgage interest rate. A fixed rate offers stability and predictable payments, making it easier to plan your long-term finances. In this article, Luc, mortgage advisor at OHAO, explains what a fixed mortgage interest rate is, how it works, and when it might be the right choice for you.

What is a fixed mortgage interest rate?

A fixed mortgage interest rate means your interest rate stays the same for the entire duration of your agreement, providing predictable monthly payments and helping you plan your finances.

For example, if you choose a 3.8% fixed rate for 10 years, you will pay the same amount every month for the next decade—even if interest rates in the Dutch market increase or decrease.

However, a fixed interest rate comes with its own costs — it is usually higher than a variable mortgage interest rate. For example, if you choose to fix your interest rate for a longer period, you can expect to pay a higher rate. Banks and mortgage lenders do this to protect themselves from inflation and the unexpected economic changes that may occur in the future.

When should you choose a fixed-interest rate?

A fixed-rate mortgage is ideal for homebuyers who prefer stability and want to avoid any surprises when paying their mortgage. Before deciding between a fixed or variable mortgage interest rate, you should consider your financial situation and future plans. Ask yourself: How long do I plan to stay in the property? Can I handle potential increases in my monthly payments? How important is payment stability to me?

If you need guidance or want to see how your monthly payments might look in the future, feel free to contact our mortgage advisors. We provide personalized calculations that show exactly how different rates will impact your monthly payments and overall costs.

What happens when your fixed interest rate expires?

When your fixed‑rate period ends in the Netherlands, your mortgage will be converted to a variable interest rate unless you refinance or lock in a new fixed rate. The rate you receive will be based on current market conditions. For personalized advice and current interest rate offers, schedule a call with our mortgage advisors.

Pros and cons of fixed mortgage interest rates in the Netherlands

Pros:

• Predictable payments: a fixed-rate mortgage offers stable monthly repayments, making budgeting easier.

• Long-term security: choose a fixed term that aligns with your future plans.

• Protection against market rate increases: even if market rates rise, your rate will remain unchanged.

Cons:

• No benefit if rates decrease: you won’t benefit from lower rates if interest rates in the market fall.

• Early repayment penalties: if you decide to break a fixed-period and leave the deal, it can come with fees, which may be costly.

• Potential higher rates after the term: If you don’t secure a new deal after the fixed term, you may be switched to a higher variable rate.

Note: you can always refinance your fixed interest rate, although penalties may apply, depending on your lender’s policies. For more details, please contact our team.

Example: fixed vs. variable interest rates

Let's say you plan to get a mortgage and want to understand the difference between fixed and variable mortgage interest rates in terms of monthly payments.

Here:

• 10-year fixed-rate mortgage at 3.4%: your monhtly mortgage payment will be approx. €2,952.54 for the entire 10-year term.

• 10-year variable-rate mortgage at 4.1%: your monthly mortgage payment will be approx. €3,051.63 for the entire 10-year term. (Keep in mind that the 4.1% rate is subject to market fluctuations and may increase or decrease during the term.)

Are mortgage rates expected to decrease or increase?

Mortgage rates are influenced by a variety of factors, including inflation, the economy, global events and the policies of the Dutch Central Bank and the European Central Bank.

If inflation decreases or the economy slow down, the Dutch Central Bank may lower interest rates, which could eventually lead to lower mortgage rates. However, it’s difficult to predict when it will happen, as economic conditions can change quickly.
