What is the Late Fee Calculator?
Enter the invoice amount, due date and payment date (or today), then choose how the late fee works: a flat fee, a percentage per month, or annual interest charged daily. You get days overdue, the late fee and the total now payable – handy for freelancers, landlords and small businesses.
How to use the Late Fee Calculator
- Enter amount and dates.
- Choose the fee method and rate.

Can I charge any late fee?

This Late Fee Calculator is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
