How is a late fee calculated?
This calculator uses simple interest on the invoice amount for the days it is overdue: a monthly rate is spread over 30-day months, an annual rate over 365 days. 1.5% per month on 1,000 for 30 days is 15.
Can I charge any late fee I like?
No. Many countries cap late-payment interest or set a statutory rate, and a fee usually has to be agreed in your terms before the work. Check the rules where you and your client are.
