How the maximum mortgage is calculated in the Netherlands?

Your maximum mortgage is calculated using regulated affordability rules based on your gross income (including salary, holiday pay, and structural bonuses), mortgage interest rates, and fixed-rate period.

Buying a home in the Netherlands starts with one crucial question: how much can I actually borrow? Many people assume the answer depends only on salary, but in reality, your maximum mortgage is calculated on a combination of financial and property-related factors.

This blog article is written by Bart, mortgage advisor at OHAO advisors, and provides a clear expert overview of how maximum mortgage calculations work in the Netherlands.

It covers key factors such as income, bonuses, interest rates, financial obligations, property value, energy efficiency, and employment type. For a quick estimate, you can use our mortgage calculator Netherlands.

Gross annual income: the starting point

Mortgage lenders assess your gross annual income, which forms the foundation of your borrowing capacity.

As a general rule of thumb, you may be able to borrow around 4.25 times your gross annual income, although this is only an indication. The final amount depends on several additional factors discussed below.

What counts as income?

In addition to your base salary, lenders may include:

  • Holiday pay (vakantiegeld)

  • Fixed allowances

  • Other recurring income

  • Irregular or one-off bonuses are usually excluded or only partially counted.

Mortgage interest rates & fixed-rate periods

Mortgage interest rates have a major impact on your maximum mortgage:

  • Lower interest rates = lower monthly payments = higher borrowing capacity

  • Higher interest rates = higher monthly costs = lower maximum mortgage.

Even a small difference in interest rate can notably affect on your maximum mortgage in the Netherlands.

How about a fixed interest rate?

The length of your fixed-rate period also matters:

  • Longer fixed periods (20–30 years) provide payment certainty and may allow higher borrowing

  • Shorter fixed periods may limit borrowing due to forthcoming interest rate risk.

Mortgage type: annuity vs linear

The type of mortgage you choose influences how much you can borrow.

Annuity mortgage

  • Monthly payments remain roughly the same

  • Higher interest costs in the early years

  • Lower starting monthly payments
    which is often allows a slightly higher mortgage.

Linear mortgage

  • Higher initial payments

  • Faster principal repayment

  • Lower total interest costs over time.

Because annuity mortgages initiate with lower payments, lenders typically allow higher borrowing.

Loan-to-value: borrowing up to 100%

A key advantage of the Dutch housing system is that you can borrow up to 100% of the property’s market value.

This means the full purchase price of the home can be covered by a mortgage, while additional buyer’s costs and closing fees must be paid from your own savings.

Additional costs: how much own money do you need?

Although the mortgage can cover 100% of the home’s value, you still need savings for buyer’s costs, including:

  • Notary fees

  • Mortgage advice and arrangement fees

  • Property valuation

  • Technical inspection

  • Transfer tax (if applicable).

These costs usually add up to 4–6% of the purchase price. You can contact our mortgage advisors for a personalised calculation, or use our closing cost calculator to estimate how much savings you will need to complete the mortgage.

Personal financial obligations & BKR registrations

Lenders never look at your income on its own. They also factor in your existing financial commitments:

  • Student loans

  • Personal loans

  • Credit cards

  • Car loans or lease contracts

  • Alimony payments

  • BKR registrations.

All monthly obligations reduce the amount you can safely allocate to mortgage payments.

Energy label & sustainability

Energy efficiency is increasingly important in Dutch mortgage calculations.

Higher energy label = higher mortgage

Homes with better energy labels (A, B, A++) may allow higher borrowing because:

  • Monthly energy costs are lower

  • The property is considered more future-proof.

Extra borrowing for sustainability

For homes with lower energy ratings, lenders may allow additional borrowing for:

  • Insulation

  • Solar panels

  • Heat pumps

This makes sustainable upgrades more accessible.

Mortgages for self-employed borrowers (ZZP & BV owners)

ZZP / freelancers

Mortgage assessments are usually based on income from the last 12 months after KvK registration.

BV owners

Banks typically assess income using the last three years, including:

  • Salary

  • Dividends

  • Company performance.

What do mortgage lenders analyze?

Mortgage lenders and banks also check the following when applying for a mortgage:

  • Gross and net income

  • Profit margins

  • Cash flow

  • Annual accounts and forecasts.

Consistency and financial stability are key factors that banks consider. Your accountant plays an important role in preparing the required documentation.

Mortgage interest deduction: a major Dutch advantage

One of the biggest advantages of the Dutch mortgage system is the mortgage interest deduction. If you meet the conditions, the interest you pay on your mortgage can be deducted from taxable income, reducing your tax burden and improving affordability.
