Late fee calculator
Work out the late fee on an overdue invoice. Percentage fees are simple interest at your monthly rate, counted per day late (1.5% a month is 0.05% a day).
Before you charge a late fee
A fee is only enforceable if the customer agreed to it before the work started, and many places cap the rate. See late payment fee wording for clauses to put in your terms and on your invoices. This calculator is general information, not legal advice.
