A/R Aging Distribution Calculator
Enter your four A/R aging buckets and see how the balance is distributed — including the share sitting over 90 days, which is where collection rates fall and filing windows close.
Your A/R by age
The four bucket balances off your aging report, as of one date. Age them the same way every time — from date of service or from date of submission, but not a mix.
Current. Claims still inside a normal adjudication cycle.
Ageing. Past a typical payer turnaround, worth a status check.
Late. Usually already reworked once, or waiting on something.
The bucket that matters. Collection rates fall sharply here, and timely-filing windows start closing.

Why the shape matters more than the total
Two practices can carry the same accounts receivable balance and be in completely different positions. One has it spread across current claims that will pay next month; the other has half of it sitting past ninety days, where collection rates fall and timely filing windows start closing. The total says nothing about which one you are. The distribution does.
This is the companion figure to days in A/R, and it answers the question that average cannot. Days in A/R is a mean, and a mean hides its tail: a practice collecting most claims in three weeks can hold a perfectly respectable average while a stubborn block of old claims quietly ages out of every filing window it had.
Age everything the same way
A bucket is only comparable to last month’s bucket if both were aged from the same event. Ageing from date of service and ageing from date of submission produce different distributions for the identical book of business, and the gap between them is your charge lag. Pick one, write it down, and use it every time.
There is no target distribution here and no benchmark. What counts as healthy depends on payer mix, specialty, and how much of the balance is patient responsibility — read this as a trend against your own history instead.
Working the old bucket
Old claims are old for a reason, and the reason is usually recorded. Start with tracking claims for finding the quiet ones, and if what is holding them is a denial, the denial code decoder turns the code on the remittance into the next action.
