Disclaimer

Please read this before you rely on any result from the calculator.

Indicative calculations only

The calculator gives indications based on the Dutch rules for 2026 as we understand them, last checked on 21 September 2026. It assumes those rules and your income stay the same for the whole term, and it leaves out several situations described on How it works. Actual payments, tax and costs can be different.

Not financial or tax advice

Nothing on this site is personal financial, mortgage, tax or legal advice, and it is not a recommendation to buy, borrow or invest. The calculator does not take your full situation into account. Before you decide, talk to a mortgage adviser who is registered with the AFM and a tax adviser.

No liability

We take care to keep the rules and calculations correct, but we cannot guarantee they are complete, correct or up to date. To the extent the law allows, we are not liable for any loss arising from using the calculator or relying on its results.
