Average Days Late Calculator
Late payments can strain business operations, disrupt cash flow, and signal poor customer payment behavior. One of the most straightforward ways to measure this problem is through the Average Days Late (ADL) metric. It tells you, on average, how many days your invoices are paid past their due date.
The Average Days Late Calculator is a quick and efficient tool that helps businesses, freelancers, and finance professionals measure payment delays. Whether you’re managing accounts receivable or analyzing customer behavior, this calculator can help you uncover patterns and make smarter financial decisions.
Formula
The formula for Average Days Late is:
Average Days Late = Total Days Late for All Invoices ÷ Number of Late Invoices
This gives a single number showing, on average, how many days past due invoices are paid.

Example
Suppose your company had 12 late payments, and the total days overdue across all of them added up to 96.
Average Days Late = 96 ÷ 12 = 8 days
That means your customers are paying, on average, 8 days late beyond the due date.
