How it works

Our calculator uses the legal late payment rate for each country, based on current legislation:

  • EU countries: ECB reference rate + 8 percentage points (or country-specific rate)
  • UK: Bank of England base rate + 8 percentage points
  • US: Estimated at 18% annually (varies by state)
  • Canada: Estimated at 3% monthly (varies by province)
  • Australia: Estimated at 10% annually (varies by state)
  • Latin America: Country-specific rates (Brazil 12%, Mexico 9%, Argentina 36%, Colombia DTF+6)
  • India: 3x RBI repo rate for MSMEs
  • UAE: Estimated at 9% annually (varies by contract and free zone)

Fixed compensation (where applicable) is added automatically based on the country:

  • EU: €40 per invoice
  • UK: £40–£100 depending on invoice size
  • Other countries: Varies by law
