Late-payment penalty calculator
Unpaid invoice? Work out the late-payment penalties, add the €40 fixed recovery fee, and get a chaser letter ready to send. Based on the French Commercial Code, free and no sign-up.
How do you calculate late-payment penalties in France?
The formula is straightforward: amount due × annual penalty rate × days late ÷ 365. Lateness starts the day after the due date shown on the invoice.
Absent a clause in your terms, the legal minimum rate is the European Central Bank's key rate plus 10 points. Many businesses set three times the statutory interest rate in their terms, which is permitted.
On top of that, a flat recovery fee of €40 is automatically due on any business-to-business invoice paid late (article L441-10 of the French commercial code). It applies per invoice, not per customer, and is owed whether or not it is claimed. Between businesses the payment term is 30 days after receipt by default, and may be extended to 60 days, or 45 days end of month, by agreement.

Frequently asked questions
How do you work out late-payment penalties on an invoice?
Penalties = amount owed × annual penalty rate × (days late / 365). Failing a contract clause, the legal minimum rate is the ECB policy rate plus 10 points; terms of sale often set three times the French statutory interest rate.
What is the €40 fixed recovery fee?
On any business-to-business invoice paid late, a fixed recovery fee of €40 is payable as of right, on top of the late-payment penalties (article L441-10, French Commercial Code).
What is the legal payment term between businesses?
Failing an agreement, the term is 30 days from receipt. It can be extended to 60 days (or 45 days end of month) where the parties agree.
