If a business client pays you late, EU law entitles you to statutory interest from the day after the due date, plus a fixed €40 recovery fee per late invoice, even if your contract never mentioned either. The calculator above works out both, splitting the overdue period at each half-year so every day uses the rate that was in force at the time.
How it works
The EU Late Payment Directive (2011/7/EU) (opens in a new tab) sets the minimum: the European Central Bank's main refinancing rate on 1 January or 1 July, plus at least 8 percentage points, fixed for that half-year. Several countries go further:
| Country | Statutory rate for business invoices |
|---|---|
| Netherlands | ECB rate + 8 points (wettelijke handelsrente) |
| Belgium | ECB rate + 8 points, rounded up to the next half point |
| Germany | Base rate (Basiszinssatz) + 9 points |
| France | ECB rate + 10 points, unless your terms set another rate |
| Other EU countries | At least ECB rate + 8 points |
Interest is simple interest on the unpaid amount, counted per day over a 365-day year. The €40 is a flat amount per invoice that covers your recovery costs. If those costs are higher, you can usually claim reasonable additional costs too.
When the clock starts
- With an agreed due date: from the day after it.
- Without one: 30 days after your client received the invoice (or the goods or services, if later).
- Payment terms: between businesses, terms over 60 days are only valid if expressly agreed and not grossly unfair to you. Public bodies must generally pay within 30 days.

Prevent the late payment in the first place
Most invoices are paid late because they're easy to put off. Billebly sends polite reminders before the due date, on the day, and once it's overdue, each with a payment link so your client can pay in seconds. That works far better than a stern letter three weeks later.
