How to Read an AR Aging Report in 2026 (and the Reports That Matter)

An accounts receivable aging report groups your unpaid invoices by how overdue they are, in buckets of current, 1 to 30, 31 to 60, 61 to 90, and 90 plus days. It tells you how much cash is tied up and how old it is. To read it, start with the total outstanding, then look at how much sits past 60 days, because that is the cash most at risk of never landing.

What is an AR aging report?

A table of every open invoice, grouped by age. Each row is a customer, each column is a time bucket, and the totals show where your receivables are stacking up. A healthy book leans toward current and 1 to 30. A book with weight in the 60 plus columns is telling you cash is stuck.

What do the aging buckets mean?

Each bucket carries a different level of risk, and a different next action.

How do you read an AR aging report?

1. Start with total outstanding, the sum of everything unpaid.
2. Read the buckets left to right. Current and 1 to 30 are normal.
3. Flag anything past 60 days. That is where cash turns into risk.
4. Scan by customer. A few large accounts usually drive most of the aged balance.
5. Compare to last month. The trend matters more than the snapshot.

What is a healthy aging distribution?

There is no single right answer, but a strong book keeps the large majority of its balance in current and 1 to 30, with very little past 90. If your 60 plus buckets are growing month over month, collections are falling behind faster than new invoices are being paid, and DSO will climb to match.

What is a good DSO in 2026?

Days sales outstanding is the average number of days it takes to get paid. The cross-industry average is about 59 days (Allianz), and it varies by sector. Lower is better, and the trend matters more than the absolute number. Teams running Monk see a 40% or greater reduction in DSO.

What other AR reports do finance teams need?

An aging report is where you start. These reports round out the picture:

• DSO and ADD. How fast you get paid, and how late the late ones are.
• Billed vs collected. What you invoiced against what actually came in.
• Deductions and short-pays. Where money leaks out of invoices that were paid.
• Recoverable AR. The overdue cash you can realistically still collect.
• Payment risk. The accounts about to slip before they do.

How do you use an aging report to prioritize collections?

Work the report by risk and size, not top to bottom. The invoices in 61 to 90 with large balances are where a call changes the outcome. The 90 plus bucket usually needs a decision about whether to escalate or write off. And a cluster of small, current invoices from one customer can signal a billing issue worth a single conversation.

What does the aging report tell you about bad debt?

The 90 plus bucket is your early read on bad debt. Money that ages past 90 days is far less likely to be collected, so a growing 90 plus column is a signal to escalate now, while there is still a relationship to work.

Why does a static aging report fall short?

An aging report is a photograph of last month. By the time it is compiled, the picture has moved. It shows a balance and stops there, so it never tells you why an invoice is unpaid or which account is about to slip. That is the difference between a report you read and a report you can act on.

How do Monk reports work?

Monk turns your receivables into live reports that update as customers pay. Ask a question about your AR in plain language and get the answer back with a chart, with no report to build. Aging, DSO, billed vs collected, deductions, and recoverable AR all sit in one place, updated in real time, so the number you are looking at is the number right now.
