Invoice Late Fee Formula

The following equation is used to calculate the Invoice Late Fee.

ILF = OI * IR * D
  • Where ILF is the invoice late fee ($)
  • OI is the original invoice amount ($)
  • IR is the daily interest rate (decimal)
  • #D is the days overdue

To calculate the invoice late fee, multiply the original invoice amount by the daily interest rate by the number of days overdue.

What is an Invoice Late Fee?

Definition:

An invoice late fee is a penalty charged to a client or customer for not paying an invoice by its due date. It compensates the issuer for the delay in payment and encourages timely settlements.

How to Calculate Invoice Late Fee?

Example Problem:

The following example outlines the steps and information needed to calculate the Invoice Late Fee.

First, determine the original invoice amount. In this example, the invoice is $1,000.

Next, determine the daily interest rate. In this case, the daily interest rate is 0.05% (or 0.0005 as a decimal).

Then, determine the number of days overdue. For this example, it is 30 days overdue.

Finally, calculate the invoice late fee using the formula above:

ILF = OI * IR * #D

ILF = 1000 * 0.0005 * 30

ILF = $15
