What we do
AllCalculatorNl is an independent collection of free calculators built around Dutch rules and Dutch search habits. Some tools answer high-stakes questions, such as what a €5,000 gross salary is worth after tax or what the 30% ruling adds. Others are everyday helpers like a laminate floor estimator or a calorie target. Each calculator is followed by a written explanation that shows the formula, the 2026 figures used and the situations where the result can be wrong.
Why this site exists
Most calculators give you a number and nothing else. When you are deciding on a mortgage or a job offer, a number without reasoning is hard to trust. We write each page so you can check the logic yourself and take the right questions to an adviser, a lender or the Belastingdienst.
Language and scope
The whole site is in English, written for residents, expats, students and newcomers in the Netherlands as well as anyone searching for Dutch tax and money calculators. Where a Dutch term is the official name (box 3, bijtelling, vakantiegeld, ZZP, transitievergoeding), we use it and explain it in plain English.
How we keep it accurate
Figures are taken from the Belastingdienst, Rijksoverheid, UWV and major Dutch tax publishers, cross-checked where sources differ, and dated on every page. Read the details in How We Calculate and our Editorial Policy. If you spot an error, tell us and we will check it.
What we are not
We are not a bank, tax adviser, lender or medical provider, and we do not sell financial products. See the disclaimer.
