About this tool
What the Accounts Payable Aging Calculator does
An accounts payable ageing schedule shows how much you owe suppliers and how overdue it is. Paying in the right order protects key suppliers and avoids late fees and interest, which many contracts charge monthly on overdue balances.
Formula
- Overdue = total payables − amount not yet due
- Share overdue = overdue ÷ total
- Late fee exposure = overdue × monthly late fee rate
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Payables by age | 4 entries |
| Late fee or interest per month | 1.5% |
| Result | Value |
|---|---|
| Overdue amount | $65,000 |
| Share overdue | 40.6% |
| Late fee exposure per month | $975 |
| Total payables | $160,000 |
How to read the result
Pay suppliers critical to operations first, then those charging the highest late fees.
A rising overdue share is an early warning of cash pressure; review it alongside the cash flow forecast.
