Days in A/R calculator
Calculate days in accounts receivable from your total A/R, total charges over a period, and the length of that period.
Updated
Enter your own figures to calculate days in A/R — the average number of days it takes to collect payment after a service is delivered.
The calculation divides your total accounts receivable by your average daily charges, which it derives from the charge period you enter.
The outstanding A/R balance at the end of the period.
Gross charges billed across the period below.
The length of the charge window — for example 90 or 365 for a trailing 90-day or 12-month figure.
A goal you set — shown as a marker on the gauge. Not a benchmark and not required.
Enter your figures to see the result and a breakdown.
How it’s calculated
Total accounts receivable ÷ (Total charges over a period ÷ number of days in that period)
Equivalently: total A/R ÷ average daily charges. The charge period (for example a trailing 90 or 365 days) must be stated for the figure to be comparable.
What this assumes
- The charge period you enter defines the average daily charges the result is built on. State that period whenever you report the figure, or it cannot be compared.
- Total A/R is measured at a point in time; charges are measured across the period. That mix is inherent to the standard formula.
- The result is the arithmetic on the numbers you entered. It is not compared to a benchmark, because a reasonable range depends heavily on payer mix and specialty.
How to read the result
A lower days-in-A/R generally signals a healthier, faster cycle, but a reasonable range depends heavily on payer mix and specialty. Read it as a trend over time and alongside an A/R aging breakdown rather than a single target — treat any benchmark as directional, not absolute.
