Unpaid invoice cost calculator

Late payment has two costs: not having the money, and the time spent asking for it. This prices both on your own figures rather than a number from a survey.

Free, no sign-up, nothing to enter but the numbers. Your figures stay in your browser.

Your overdraft rate, or what the money would earn sitting in the bank.

What an hour of your time is worth — the hours spent chasing are hours not spent on billable work.

Cost of money tied up

Value of time chasing

Deliberately conservative: this counts only the cost of not having the money and the value of the hours spent chasing it. It does not try to price the work you turned down for cash-flow reasons, or a client relationship soured by chasing.
