How is a late fee calculated?
A percentage late fee is the unpaid balance times the rate, for the time the invoice is late. A flat fee is the same amount however late it is.
| Late fee type | Formula | Example on $1,200, 45 days late |
|---|---|---|
| 1.5% per month | Balance x 1.5% x (days late / 30) | $27.00 |
| 18% per year | Balance x 18% x (days late / 365) | $26.63 |
| Flat fee | Same amount once the invoice is late | $35.00 |
Questions people ask
It depends on your contract and your state. Many businesses charge 1% to 1.5% a month on the unpaid balance or a small flat fee, but some states cap late fees and interest, so check your state's limits first.
Yes, you should. Put the late fee in your contract or estimate and on every invoice before the due date. A fee the client never agreed to is hard to collect.
Not quite. A flat late fee is a one-time charge. Interest grows with time, usually as a monthly or yearly percentage of the unpaid balance.
No. Invoicefy sends automatic reminders before and after the due date, and you add a late fee to the invoice yourself if your terms allow it.
Keep it short and specific, for example: "Payment is due within 30 days. Balances unpaid after the due date are charged 1.5% per month."
Let reminders chase it for you.
Invoicefy emails your client before and after the due date, with the pay link inside, and stops when they pay.
