Questions

What's a Typical Late Fee?

1% to 1.5% of the invoice per month is common, as is a flat fee such as $25. Whatever you choose, it has to be in your terms before the invoice is late, ideally printed on the invoice itself.

How Does a Monthly Late Fee Add Up?

This calculator charges the percentage for each started 30 days past due. A $2,400 invoice 45 days late at 1.5% per month is two periods: 2 × $36 = $72.

Are Late Fees Limited?

Often, yes. Many states cap interest rates or late fees, and rules differ for consumers and businesses. Check what applies where you and your client are before you charge one.
