Maximum Mortgage Calculator 2026

How Much Can You Borrow for a Home in the Netherlands?

One of the first and most important questions when planning to buy a home in the Netherlands is: how much can I actually borrow? Your maximum mortgage determines your property budget and, by extension, the neighborhoods and property types within your reach. For expats and international workers, this question carries additional complexity because of the 30% ruling, international income structures, and the unfamiliarity with Dutch lending standards.

The Netherlands uses a responsible lending framework established by NIBUD (Nationaal Instituut voor Budgetvoorlichting), the National Institute for Budget Information. NIBUD calculates annually what percentage of income can be responsibly spent on housing costs, considering various income levels and interest rates. All Dutch mortgage lenders are legally required to follow these norms, ensuring that borrowers do not take on more debt than they can handle. This is both a protection and a constraint, and understanding how it works is essential for making realistic property plans.

NIBUD Lending Standards: The Framework Explained

NIBUD uses housing expense ratios (woonlastpercentages) to determine the maximum amount you can spend on housing. These ratios vary based on two primary factors: your gross income and the prevailing mortgage interest rate. The higher your income, the greater the percentage of it you can allocate to housing, because essential living costs (food, transport, insurance) consume a smaller share of your budget.

At a mortgage interest rate of approximately 4% in 2026, you can generally borrow around 4.5 times your gross annual income. However, this multiplier changes with the interest rate environment:

As you can see, each percentage point of interest rate difference translates to approximately €15,000 in borrowing capacity on a €60,000 income. This underscores the importance of finding the most competitive interest rate and explains why even small rate differences between lenders are worth pursuing.

Income Types and How They Count

Understanding which parts of your income count toward mortgage calculations is crucial for expats, who often have complex compensation structures.

Fixed Salary

Your base gross annual salary, including the mandatory 8% holiday allowance (vakantiegeld), forms the foundation of your mortgage calculation. If you have a permanent contract (vast contract), banks accept this income at full value. For many international workers in the Netherlands, particularly in technology, finance, and corporate sectors, the permanent contract is standard after an initial probation period.

Variable Income

Bonuses, overtime pay, shift allowances, and commissions are considered variable income. Banks typically count the average of the last three years of variable income. If your variable income shows an upward trend, some lenders may give additional weight to recent years. This is particularly relevant for expats in sales or consulting roles where bonuses form a significant part of compensation.

Dual Income Calculations

Since 2026, the full income of both partners is counted toward the maximum mortgage. This is a significant change from previous years when the lower income was only partially included. For expat couples where both partners work, this dramatically increases borrowing capacity.

Example: Partner A earns €70,000, Partner B earns €45,000. Combined income: €115,000. At a 4% interest rate, the maximum mortgage is approximately €115,000 x 4.5 = €517,500. If only Partner A's income were counted, the maximum would be approximately €315,000, a difference of over €200,000.

The 30% Ruling Complication

For expats with the 30% ruling, determining the "income" for mortgage purposes is where things get complicated. There are essentially three approaches banks take:

• Conservative approach: the bank uses only your taxable income (70% of gross). This significantly reduces your maximum mortgage. On an €80,000 salary, they would calculate based on €56,000, giving a maximum mortgage of approximately €252,000.
• Moderate approach: the bank uses your full gross salary but stress-tests whether you can afford payments after the 30% ruling expires. This gives you a higher maximum but still considers the income drop.
• Flexible approach: the bank uses your full gross salary for the calculation. This is the most favorable for borrowers but offered by fewer lenders.

Practical advice: if you have the 30% ruling, work with a mortgage advisor who has relationships with multiple banks. The difference between a conservative and flexible lender can mean €100,000+ in borrowing capacity. Banks like ABN AMRO and ING are generally known for being more expat-friendly, though policies can change. An independent advisor can navigate this landscape for you.

How Student Debt Affects Your Borrowing Capacity

If you have student debt, whether from the Netherlands (DUO) or from abroad, it will reduce your maximum mortgage. The reasoning is straightforward: existing debt obligations consume part of your income that would otherwise be available for mortgage payments.

For Dutch DUO student loans, the impact depends on when the loan was taken:

• New loan system (leenstelsel, from 2015): 0.45% of the original principal is counted as a monthly debt obligation, regardless of how much you have already repaid.
• Old system (basisbeurs, before 2015): 0.65% of the original principal is counted.

Example: you have a DUO student loan with an original principal of €25,000 under the new system. Monthly deemed debt obligation: €25,000 x 0.45% = €112.50 per month. At 4% interest, this reduces your maximum mortgage by approximately €25,000-30,000.

For foreign student loans, banks apply similar principles but may require documentation of the original loan amount, current balance, and monthly payments. Providing clear, translated documentation helps speed up the process.

Strategic consideration: if you have a small student loan that is almost paid off, consider fully repaying it before applying for a mortgage. The increase in borrowing capacity can far exceed the loan amount.

Energy Labels and Your Maximum Mortgage

A relatively new factor in Dutch mortgage calculations is the energy label (energielabel) of the property. Homes with better energy efficiency ratings may qualify for a higher maximum mortgage. The logic is that energy-efficient homes have lower utility costs, leaving more of your income available for mortgage payments.

In 2026, some lenders offer an additional €9,000 to €15,000 in borrowing capacity for homes with an energy label of A or better. Additionally, if you plan to make energy-saving improvements (insulation, solar panels, heat pump), you may borrow extra specifically for these renovations, sometimes up to €20,000 beyond the standard maximum.

For expats, this is particularly relevant when choosing between properties. An older property with a poor energy label (E, F, or G) may have a lower purchase price but will limit your mortgage capacity and result in higher monthly utility costs. A well-insulated property with a good energy label can be more affordable in the long run.

The 100% LTV Rule and Buyer's Costs

In the Netherlands, you can borrow up to 100% of the appraised market value of the property. This is called the loan-to-value (LTV) ratio. Unlike many other countries, the Netherlands does not require a mandatory down payment on the property itself.

However, you must pay buyer's costs from your own savings. These costs, known as "kosten koper" (k.k.), include transfer tax, notary fees, mortgage advisor fees, and property valuation. They typically amount to 4-6% of the purchase price. For a €400,000 property, you need approximately €16,000-24,000 in cash.

Important distinction: the appraised value may differ from the purchase price. In a hot market where buyers pay above asking price, the appraised value might be lower than what you paid. In this case, you need additional cash to cover the difference, as banks will only lend up to the appraised value.

Maximum Mortgage Examples for Expats in 2026

These are estimates. Actual amounts depend on your specific debts, the lender's policies, and the exact interest rate offered.

Other Debts That Reduce Your Borrowing Capacity

Student loans are not the only obligations that lower your maximum mortgage. Banks consider all recurring financial commitments when assessing your borrowing capacity. For expats, some of these may be less obvious:

• Personal loans: the monthly repayment amount is fully deducted from your available housing budget. A €500/month car loan can reduce your maximum mortgage by approximately €100,000.
• Revolving credit (doorlopend krediet): even if you have not drawn on the credit line, 2% of the total credit limit is counted as a monthly obligation. A €10,000 revolving credit facility reduces your mortgage capacity by approximately €40,000. Close unused credit lines before applying.
• Private lease vehicles: the monthly lease payment is counted as a fixed obligation. If you are leasing a car for €400/month, this could reduce your mortgage capacity by approximately €80,000.
• Alimony payments: if you pay alimony to a former spouse or children, this is deducted from your available income for mortgage calculations.
• Buy-now-pay-later arrangements: outstanding balances on deferred payment plans are increasingly being registered and may affect your BKR credit registration.

Before applying for a mortgage, request your BKR credit report (Bureau Krediet Registratie). This report shows all registered debts in the Netherlands. Expats who have lived in other countries should also check that any foreign debts they declare are accurately represented. Some lenders also ask for credit reports from your home country.

Tips to Increase Your Maximum Mortgage

• Pay off debts before applying: eliminating a €200/month car lease payment can increase your mortgage capacity by €40,000-50,000. Close unused credit cards and revolving credit lines.
• Increase your income: a salary raise, even a modest one, directly increases your maximum mortgage. Negotiate before applying for the mortgage.
• Buy with a partner: dual incomes are now fully counted, making co-purchasing extremely advantageous.
• Choose a competitive interest rate: lower rates mean you can borrow more. Even 0.1% makes a difference over 30 years.
• Consider NHG: the interest rate discount with NHG indirectly increases your borrowing capacity.
• Target energy-efficient properties: homes with good energy labels may qualify for additional borrowing capacity.
• Use an independent mortgage advisor: they compare all lenders and know which ones are most favorable for your situation, especially regarding the 30% ruling.
