Open generatorHow to use these tools
- Choose the right tool: the calculators for statutory interest (overdue claims) or transition payment (end of employment); the generators for a demand letter or a settlement agreement.
- Enter the requested details. Each tool includes sensible defaults and short hints under each field.
- Review the result: for the calculators, a clear total amount with a step-by-step breakdown and legal basis; for the generators, a ready-to-use draft document.
- Export: the calculators to PDF, Excel or TXT; the generators as a Word document (and TXT).
- Have the result verified by a Dutch lawyer before signing or filing. The tools are accurate but cannot capture every fact-specific nuance.
Why use a Dutch law calculator?
Both Dutch statutory interest and the transition payment have strict statutory formulas set out in the Dutch Civil Code. The amount is fixed by law, but the calculation is easy to get wrong: interest rates change every six months, the transition payment depends on a broader salary base than the basic salary alone, and statutory caps shift each calendar year. Errors regularly cost employees thousands of euros in underpaid severance, and creditors thousands of euros in uncollected interest.
These tools follow the current statutory formulas (with rate tables updated semi-annually for interest, and the annually published cap for the transition payment) so you can verify any calculation made by an employer, debtor, or counterparty.
