What is equity and how do you calculate it?

Want to know exactly what the surplus value of your home means and how to calculate it yourself? You're not the only one, because more and more people want to know what their home is really worth. This is important if you are considering a home equity mortgage.

Definition and creation of equity

Surplus value is the difference between the current market value of your home and the outstanding mortgage. Suppose your house is now worth €400,000 and your mortgage is still €100,000, then you have €300,000 surplus value. This excess value usually arises because house prices rise, you make extra repayments or renovate. According to recent figures, the average excess value in the Netherlands is about €175,000. By preserving or renovating your home, your equity can increase even further. The good news: you don't have to move to use your surplus value. However, a current appraisal or recent WOZ value is important to determine the correct amount. Note that renovations or energy-saving investments can positively affect the value of your home. This makes the surplus value mortgage an interesting option to increase your financial space.

Ways to calculate your equity

You can calculate the surplus value in different ways. Banks and independent advisors offer online calculation tools. These give a quick indication, but an official appraisal is usually the most accurate. WOZ value and appraisal report differ: the WOZ is an estimate from the municipality, while an appraisal provides an up-to-date and personal report. An appraisal is often more reliable, especially if you are applying for an excess value mortgage.

Follow this roadmap:

• Get your current mortgage status from your bank.

• Check the WOZ assessment of your home.

• Get an appraisal for an exact value.

• Subtract the outstanding mortgage from the market value.

• Consider costs such as appraisal and advisory fees.

Absorbing Surplus Value: Options in 2026.

Want to know what options you have in 2026 to make smart use of your home's surplus value? There are more roads to Rome than you think. Below is an overview of the most frequently chosen routes, each with their own opportunities and points of interest.

Increase mortgage or take out a second mortgage

A classic way to use your home equity mortgage is to increase your existing mortgage. This can be done with your current lender, but you can also opt for a second mortgage with another party. Banks look at your income, age and the current value of your home. Suppose your house is worth €400,000 and you still have €100,000 of mortgage outstanding. You want to withdraw €30,000 for a renovation. The bank assesses whether you can bear the extra monthly expenses. A second mortgage sometimes has a different interest rate or shorter term, but can be useful if you can't get a loan from your current bank. Pay close attention to the differences in conditions, interest rates and costs. Always make a comparison before making a choice.

Opeethypotheek and cash in mortgage

Especially popular with people over 60 is the opeethypotheek, also known as verzilverhypotheek. This mortgage allows you to withdraw money without monthly charges. The interest is added to the debt and repaid upon sale or death. Providers such as ABN AMRO, Florius and ZilverHuis offer different variants. Advantages are the lack of monthly repayments and direct access to your assets. Disadvantage: the debt grows and your inheritance gets smaller. On average, you can redeem about 50% of the surplus value when you move with this option. It's important to look carefully at the terms and conditions and what it means for your dependents.

Withdraw equity without moving

Want to use your home equity mortgage without having to move? That is possible! For example, you can withdraw an amount for a renovation, sustainability or gift to your children. Banks offer flexible options: one-time payouts or monthly additions to your income. Note that income, age and the type of mortgage determine how much you can withdraw. Want to know how to do this smartly? Then check out our Harnessing Surplus Value Home tips for practical advice. This approach is particularly interesting if you want to continue living in your home and make targeted investments in your own home comfort or financial flexibility.

Sale & lease back: sell your house and lease it back.

Another option is sale & lease back. You sell your home to an investor and immediately lease it back. This way you get the full mortgage surplus value right away, without having to move. Advantages are the immediate payoff and retention of your place to live. Disadvantages are the often high rental costs, lack of AFM oversight and the risk that nothing will be left for your heirs. This option is especially suitable if borrowing is not possible, but pay close attention to the conditions and risks. Always get good advice before considering this step.

Advantages and disadvantages of a capital gain mortgage

Are you about to use the surplus value of your home? Then it's smart to carefully weigh the pros and cons of a home equity mortgage. That way you can make a choice that fits your financial situation and future plans.

Benefits

A home equity mortgage allows you to quickly access the money tied up in your home. You can use this 'dormant' equity for a renovation, sustainability or to supplement your pension. You don't have to move to use the excess value, which many people like. A big advantage is that you can, for example, make your home more sustainable, thus reducing your energy costs and increasing your living comfort. You can also use a surplus value mortgage to make a gift to (grand)children, or to finance major expenses. In this way you make your capital immediately available for purposes you consider important. Furthermore, you can choose different forms of withdrawal: a one-time amount or a monthly payment. This gives flexibility, especially if you want to spread your expenses over several years. In many cases you can tailor the surplus value mortgage to your needs and situation.

Disadvantages

A surplus value mortgage also has disadvantages that you should take into account. Often your monthly costs increase, especially if you opt for a regular mortgage increase. Even with a repayment-free variant, you continue to pay interest on the amount withdrawn. Does the value of your home decrease? Then you run the risk of a residual debt, especially if you withdraw a lot of surplus value. Suppose your home loses 20 percent of its value, you could end up with a substantial debt after the sale. In addition, the inheritance for your survivors decreases, sometimes even to zero if the mortgage debt equals the home value. You are also less flexible when you next move or refinance. So it is important to look ahead carefully and discuss your choices with an independent advisor.

Practical considerations and statistics

When taking out a surplus value mortgage, monthly costs rise by an average of about €336 per month if you borrow an extra €50,000. This can cause stress or uncertainty, especially if your retirement income is limited. Therefore, always make a realistic assessment of your financial space. Compare providers on interest rates, conditions and costs. Get good advice, especially with complex products such as the opeethypotheek. The right choice depends on your age, income and future plans.

Tax and regulations when taking home equity

Do you want to take out a surplus value mortgage in 2026? Then you have to deal with different tax rules and laws. It is important to know what you should pay attention to, because the Belastingdienst are watching you critically. Below you can read all about interest deduction, the bijleenregeling, tax boxes and current regulations.

Hypotheekrenteaftrek and bijleenregeling

With a surplus value mortgage you can only deduct the interest if you use the money for improvement or maintenance of your own home. Would you like to use the surplus value for a car, gift or vacation? Then the interest is not deductible in box 1, but this loan falls in box 3. The bijleenregeling is an important consideration. Do you sell your home and not use the surplus value in full for a new home? Then your right to interest deduction is limited. Want to know more? Check out the explanation of the Belastingdienst about the bijleenregeling and capital gains. In short: the destination of the money determines whether you may benefit from hypotheekrenteaftrek with a capital gain mortgage.

Tax consequences and box classification

Mortgage equity has implications for your tax return. If you use the loan for your own home, it falls under box 1. In that case you can deduct the interest (subject to conditions). Do you spend the amount for other purposes? Then the loan falls under box 3. Note: savings released by the withdrawal of excess value count in box 3. As a result, you may pay more wealth tax. Fortunately, there are exemptions, such as €57,684 per person in 2025. If you invest in sustainability, there are sometimes tax benefits. It's smart to consult an advisor beforehand, so there are no surprises.

Legal issues and regulations 2026

The rules around a home equity mortgage change regularly. In 2026, mortgage standards or tax rules may be adjusted again. So keep a close eye on the news and get advice. The Financial Markets Authority (AFM) supervises most mortgage products. With a sale & lease back construction this supervision does not always apply. So be aware of your rights and obligations. With complex products, such as a opeethypotheek, you are entitled to independent advice. This way you avoid taking out a surplus value mortgage that does not fit your situation or future plans.

Common mistakes and issues with home equity mortgages

Taking out a surplus value mortgage seems simple, but in practice many people make the same mistakes. This can have unpleasant consequences for your financial future. That's why it's smart to know the main pitfalls before you get started.

Many people take too much out of their home equity mortgage without considering future expenses. Especially if your income drops or interest rates rise, these charges can weigh heavily on your budget. People also often underestimate what a drop in home value means. According to Average Home Value Increase, home prices can fluctuate considerably, which creates additional risk of residual debt if the market falls back.

Another common mistake is insufficient understanding of the tax consequences and the bijleenregeling. Do you use the excess value for a car or vacation? Then the interest deduction expires and you may pay more tax. Also pay close attention to the type of mortgage you choose. A repayment-free variant without a future plan can cause problems when you retire or sell.

Always compare multiple providers on interest rates, terms and fees. Many people forget this, resulting in missing out on hundreds of euros per year. The lack of independent advice often leads to missed opportunities or additional risks. Seniors also sometimes make mistakes, for example by withdrawing surplus value without carefully considering the consequences for their heirs. Read how over-60s use their surplus value by over-60s and what to watch out for.

Finally, never rush into a surplus value mortgage for consumer expenses without a financial plan. Always communicate with your heirs about the impact on the estate. This way you avoid nasty surprises and keep a grip on your financial future.
