For a EUR invoice paid late, the calculator applies the French statutory margin to the ECB reference rate and breaks the result down by period.
This tool calculates interest mechanically from stored rate data. It is not legal advice. Always check the contract, governing law, debtor status, and any sector-specific rules.
Frequently asked questions
What is the standard French statutory late payment rate?
For many commercial debts, the default statutory formula is ECB MRO + 10 percentage points.
Is public procurement treated the same way?
No. Public procurement can use a different statutory margin, so check the specific public-contract rule before relying on the result.
Can a contract set a different rate?
Contracts can specify late-payment terms, but statutory minimums and mandatory rules may still apply.
