Fixed-Rate Period Mortgage Guide: Understanding Everything for 2026
Choosing a fixed-rate mortgage term is more important than ever in 2026. With rising interest rates and market uncertainty, financial security is a major concern for many people.
In this guide, you’ll learn everything about the fixed-rate period of your mortgage leading up to 2026. We’ll explain what a fixed-rate period is, what options are available, how it affects your monthly payments, and how to make the best choice for your situation.
Whether you’re a first-time homebuyer, a homebuyer moving up the ladder, or refinancing, this guide will help you make the right financial decision for your future.
What is a fixed-rate period?
Simply put, a fixed-rate mortgage period means that you lock in your mortgage interest rate for an agreed-upon period. During this period, you know exactly where you stand. Your monthly payments won’t change, even if market interest rates rise or fall. This gives many people a sense of financial peace of mind and security.
You can usually choose the term of a fixed-rate mortgage yourself. Typical terms are 1, 5, 10, 20, or even 30 years. The 10-, 20-, and 30-year terms are particularly popular because they offer a great deal of certainty. Suppose you choose a 10-year fixed-rate period. In that case, your interest rate will remain the same for 10 years, no matter what happens in the market. Only after that period will your interest rate be reassessed.
So what’s the difference from a variable-rate mortgage? With a variable-rate mortgage, the interest rate can change every month along with market rates. This means your monthly payments can go up or down. With a fixed-rate mortgage, on the other hand, you know exactly what you’ll be paying, and you avoid any surprises.
Did you know that more than 60% of Dutch homebuyers opt for a 20-year fixed-rate period? This is according to figures from Viisi. This popular type of fixed-rate mortgage provides long-term certainty about your monthly payments and prevents unexpected increases.
Of course, there are also drawbacks. The longer you lock in the interest rate, the higher the interest rate usually is. That’s because lenders take on a risk: they don’t know how interest rates will change in the future, so they charge a higher rate for longer-term certainty. Want to know more?

A fixed-rate mortgage is therefore about choosing between certainty and flexibility. Think carefully about what best suits your situation and needs.
Why is the fixed-rate period so important right now?
The decision to choose a fixed-rate mortgage has changed significantly in recent years. Since 2022, mortgage rates in the Netherlands have risen rapidly, from an average of 1.5% to sometimes even above 4%. This increase is causing a great deal of uncertainty among homebuyers and those looking to move up. No one knows exactly when—or even if—rates will fall again.
This makes the fixed-rate period of a mortgage even more important. Inflation is high, and the European Central Bank’s (ECB) policy has a direct impact on interest rates. Many experts expect that mortgage rates will not return to the low levels seen before 2022 for the time being. Want to know what the outlook is?

Rising Interest Rates and Uncertainty in the Mortgage Market
The mortgage market is in a state of flux. While you might have been able to secure a fixed-rate mortgage at 1.6% in 2021, rates are now much higher. This has a direct impact on your monthly payments and the affordability of a home. Due to inflation and the ECB’s tight monetary policy, interest rates are likely to remain on the high side for the time being.
Opting for a mortgage with a longer fixed-rate period offers protection against further increases. But it also carries the risk that you’ll be stuck with a higher interest rate if the market eventually drops. For example: someone who chose a 10-year fixed-rate mortgage in 2021 will pay a low interest rate until 2031, providing financial peace of mind.
What does this mean for your monthly payments and timing?
Many people will see their fixed-rate mortgage periods expire between 2024 and 2026. Are you about to renew or refinance? If so, your interest rate could suddenly jump significantly, causing your monthly payments to rise sharply. This makes choosing the right timing more important than ever.
If interest rates rise just as your fixed-rate mortgage period ends, the difference in your monthly payment can be substantial. At the same time, if you lock in a rate for too long now, you won’t benefit from any potential drop in interest rates. So it really comes down to a personalized approach. Consider your own situation, future plans, and financial buffer before making a decision.
AFM Reference Rate: Impact on Your Borrowing Capacity
In addition to your monthly payments, the reference interest rate set by the Netherlands Authority for the Financial Markets (AFM) plays a major role. If you choose a fixed-rate mortgage term shorter than 10 years, the bank must use a higher notional interest rate when determining your maximum mortgage amount. This means you can borrow less, even if the actual interest rate is lower.
A mortgage with a longer fixed-rate period gives you more certainty and a higher borrowing capacity. But keep in mind: a longer term often means a slightly higher interest rate. So it’s always a balance between certainty, affordability, and flexibility. If necessary, seek advice from an independent mortgage advisor to avoid any surprises.
What fixed-rate periods are available, and what are the differences?
Choosing a fixed-rate mortgage term largely determines your financial security and monthly payments. You can choose from fixed-rate periods of 1, 5, 10, 15, 20, or even 30 years. There’s also a variable-rate option, where your interest rate can change monthly. But how do you choose between all these options?
Overview of Fixed-Rate Periods
Below is an overview of the most commonly chosen terms and their characteristics:
| Term | Interest Rate | Security | Flexibility | Popular with |
|---|---|---|---|---|
| 1 year | Low | Low | High | Risk-takers |
| 5 years | Low | Low | High | First-time buyers, Expats |
| 10 years | Medium | Reasonable | Average | Most Popular |
| 15 years | Medium | Reasonable | Average | Families |
| 20 years | Higher | High | Lower | Those seeking peace and quiet |
| 30 years | Highest | Maximum | Low | Long-term thinkers |
| Variable | Fluctuating | None | Maximum | Experienced investors |
With a short-term fixed-rate mortgage, you usually pay a lower interest rate. However, you do run the risk that your monthly payments will rise significantly once the term ends. If you choose a long-term fixed-rate mortgage, you’ll pay more, but you’ll have certainty about your costs for years to come.
Pros and cons by term
Let’s list the pros and cons of each option:
- Short term (1–5 years):
- Advantage: low interest rate, high flexibility
- Disadvantage: risk of a rapid increase in monthly payments
- Medium term (10–15 years):
- Advantage: balance between security and interest rate
- Disadvantage: slightly higher interest rate than short-term loans, but greater peace of mind
- Long term (20–30 years):
- Advantage: maximum certainty regarding your payments
- Disadvantage: highest interest rate, less benefit from rate drops
Choosing a fixed-rate mortgage term therefore depends heavily on your risk profile and future plans. Want to know what the current differences are? Check out our 2026 mortgage rate comparison for the latest rates and terms.
Real-world example: the difference between 10- and 20-year fixed-rate mortgages
Suppose you take out a €400,000 mortgage. With a 10-year fixed-rate mortgage at 4%, you’ll pay about €1,910 per month. If you choose a 20-year fixed-rate mortgage at 4.2%, that comes to €1,988 per month. That’s a difference of €78 per month—just for the extra security. On an annual basis, you’ll pay €936 more for that longer-term certainty.
This calculation shows that a mortgage with a longer fixed-rate period costs more, but you know exactly where you stand. Especially if you expect to stay in your home for a long time, this can provide peace of mind.
Flexibility, moving, and penalty-free prepayment
Do you plan to move within a few years? Then a mortgage with a short fixed-rate period might seem attractive, because you can benefit more quickly from any drop in interest rates. Please note: not every lender allows you to transfer the interest rate to your next home.
The rules for penalty-free prepayment also vary by lender and term. With some mortgages, you can make additional prepayments of up to 10% or 20% annually without incurring a penalty. This can be advantageous if you expect to make extra payments, such as from an inheritance or a bonus.
In short, choosing the right fixed-rate mortgage depends on your needs, future plans, and risk tolerance. Make sure to get sound advice so you don’t run into any surprises.
How do you choose the right fixed-rate period for your situation?
Choosing the right fixed-rate period for your mortgage is often more difficult than you might think. Many personal factors come into play. To help you, we’ve created a clear step-by-step guide. This will help you make a choice that suits both your situation and the current mortgage market.
Step 1: Determine your risk tolerance
How much fluctuation in your monthly payments can you handle—and are you willing to tolerate? Those who choose a mortgage with a short fixed-rate period often benefit from a lower interest rate, but run the risk of seeing their monthly payments rise significantly once that period ends. Especially if interest rates are higher at that time. Are you sensitive to financial uncertainty? Then a mortgage with a longer fixed-rate period can give you greater peace of mind.
Step 2: Consider your housing plans
How long do you expect to stay in your current home? If you plan to move within a few years, a mortgage with a short fixed-rate period might be a good option. That way, you won’t be tied to the mortgage for long and may benefit from a lower interest rate sooner. If you plan to stay longer, a mortgage with a longer fixed-rate period offers certainty regarding your monthly payments. Also consider whether you can transfer your interest rate if you move.
Step 3: Analyze your financial situation
Will you borrow the maximum amount, or do you expect to make extra payments? Keep in mind that choosing a fixed-rate mortgage affects your maximum loan amount. If you choose a fixed-rate period of less than 10 years, the bank will use a higher benchmark interest rate in its calculations. As a result, you may sometimes be able to borrow less. Want to know exactly how much you can borrow? Use a “calculate maximum mortgage ” tool for an accurate estimate.
Step 4: Consider flexibility and future plans
Do you want the option to refinance early, make penalty-free prepayments, or do you anticipate changes such as receiving an inheritance, moving in with a partner, or starting a family? A fixed-rate mortgage with flexibility might be a wise choice in that case. List out your scenarios: Will you be receiving an inheritance soon, are you planning to buy a home together, or are you expecting a new addition to your family? Think ahead and choose a fixed-rate mortgage that fits your future plans.
Always use online calculators to run through different scenarios with your fixed-rate mortgage. And discuss your situation with an independent mortgage advisor. That way, you can be sure you’re choosing the fixed-rate mortgage that will give you long-term financial peace of mind and security.
Practical Examples and Calculation Examples
Suppose you have a mortgage of €400,000 and want to know the difference between a 10-year fixed-rate mortgage at 1.6% and a 20-year fixed-rate mortgage at 2%. If you choose a 10-year fixed-rate mortgage, you’ll pay about €1,400 per month for the first 10 years. If you choose a 20-year fixed-rate mortgage, your monthly payment will be approximately €1,478. Over ten years, you’ll pay €9,360 more with the 20-year fixed-rate option, but you’ll gain extra peace of mind. This clearly shows how choosing a fixed-rate period for your mortgage affects your monthly payments and financial peace of mind.
What happens if you choose a 10-year fixed-rate period and interest rates rise to 4% afterward? Your monthly payment will then jump to €1,741. In that case, a mortgage with a longer fixed-rate period may be more advantageous, because you’re protected against rising interest rates. If you’re considering refinancing at the end of your term, this could be a smart way to keep your monthly payment down. Read more about refinancing when your fixed-rate period ends to see what your options are.
When should you choose a short-term or long-term fixed-rate period? A short-term fixed-rate mortgage is attractive when interest rates are low and if you expect to move or make extra payments. But be aware: recent experience shows that mortgage borrowers are more vulnerable with a short fixed-rate period, especially if interest rates rise unexpectedly. If you’d like to learn more about these risks, read the article on why mortgage borrowers are more vulnerable with a short fixed-rate period.
Making extra payments can also influence your decision. If you plan to pay off your mortgage quickly, a mortgage with a short fixed-rate period can be advantageous because it allows you to remain flexible. With a variable-rate mortgage, your monthly payment fluctuates directly with market interest rates, but this introduces uncertainty. Tip: Use online calculators to run through different scenarios and find out what best suits your situation.
Common Mistakes and Pitfalls When Choosing a Fixed-Rate Period
Choosing the right fixed-rate period for a mortgage may seem simple at times, but in practice, many people make the same mistakes. By not giving enough thought to the consequences, these choices can end up costing a lot of money.
A common pitfall is opting for a short fixed-rate mortgage term simply because interest rates are low at the time. While this may seem attractive, it carries risks if interest rates rise afterward. Experts recently expressed concerns about the popularity of five-year fixed-rate mortgages, noting that people are not sufficiently aware of the potential consequences. Read more about this in the article “Concerns About the Popularity of Five-Year Fixed-Rate Mortgages.”
The opposite also happens regularly: people choose a mortgage with a long fixed-rate period without taking their future plans into account, such as a possible move or extra payments. As a result, they sometimes end up paying a higher interest rate unnecessarily.
Other pitfalls include failing to carefully read the terms and conditions regarding penalty-free prepayments or refinancing, and forgetting that the benchmark interest rate affects the maximum amount you can borrow. Focusing solely on current monthly payments provides too narrow a picture.
Finally, people often fail to seek independent advice, and many assume that the fixed-rate period of a mortgage is always predictable. In reality, no one can accurately predict interest rate trends. A well-known example: people who opted for a short-term fixed-rate mortgage in 2022 were surprised in 2024 by significantly higher interest rates when it came time to renew their fixed-rate term.
