Days in A/R Benchmark Calculator
Days in A/R measures something a denial rate never touches: once a claim is accepted, how long it takes to become cash. This tool turns your total accounts receivable and annual gross charges into a single day count, checks it against the range HFMA publishes for this exact formula, and prices what sitting above that range is costing you in trapped working capital, at a cost-of-capital rate you set yourself rather than one this tool assumes on your behalf.

Your receivable
The full outstanding receivable today, not a figure already net of write-offs or aged-off balances.
Gross charges for the trailing 12 months, not expected reimbursement. HFMA's formula runs on charges, not net revenue.
Cost of capital
Your own borrowing rate, line-of-credit cost or internal hurdle rate. No published figure applies to every organisation, so this is a placeholder to replace, not a benchmark.

Days in A/R
35.3 days
$2,900,000 in A/R against $82,192 in average daily gross charges.
Within the published rangeHFMA's cited range is a target, not a finish line. Sitting inside it still means real cash is moving through the collection cycle rather than sitting in it; the numbers below show what tightening further would be worth.
Your days in A/R against the published range
Your A/R against the benchmark ceiling, in dollars
The benchmark ceiling is what your A/R would be if you collected at exactly the top of HFMA's published range, 40 days, at your own charge volume.
Modeling estimate, not a quote or a guarantee. Assumptions are editable and every figure above is derived from the values you entered. HFMA publishes an ideal range of 30 to 40 days in accounts receivable, calculated from gross charges over the trailing 12 months.
How this is calculated
average daily gross charges = annual gross charges / 365
days in A/R = total accounts receivable / average daily gross charges
published range = 30 to 40 days, HFMA’s published ideal range for this metric
A/R at the benchmark ceiling = 40 x average daily gross charges
working capital tied up beyond the benchmark = total A/R - A/R at the benchmark ceiling, floored at zero
annual cost of the gap = working capital tied up beyond the benchmark x the cost-of-capital rate you enter
verdict: faster than the range under 30 days, within the range from 30 to 40 days, slower than the range over 40 days. HFMA publishes an ideal range of 30 to 40 days in accounts receivable, calculated from gross charges over the trailing 12 months.
Methodology and assumptions
What the model does, and what it refuses to guess
One calculation, one published comparison, and one cost estimate built on an assumption you control.
What it calculates
Days in A/R is total accounts receivable divided by average daily gross charges, where average daily gross charges is gross charges for the trailing 12 months divided by 365. That is the formula the Healthcare Financial Management Association states in 7 KPIs Providers Should Be Tracking: divide current receivables by the average daily charge amount, where the average daily charge amount is gross charges for the previous 12 months divided by 365. Use the full outstanding receivable, not a figure already reduced by write-offs or aged-off balances, and use gross charges rather than expected reimbursement, or the day count will not match anything published.
Where the 30 to 40 day range comes from
The same HFMA article states that days in A/R should range between 30 and 40 days, alongside two related thresholds it also publishes: accounts receivable over 90 days should be less than 10 percent of the total, and self-pay accounts receivable over 90 days should be less than 30 percent. Those two thresholds are not built into this calculator, which prices only the headline day count, but they are worth tracking alongside it.
HFMA publishes a second, related metric under its MAP Keys framework, FM-1, Net Days in Accounts Receivable, which uses a different formula: net A/R divided by average daily net patient service revenue rather than gross charges. The two formulas are not interchangeable and will not agree on the same books. This tool uses the gross-charges version because gross charges are the figure most organizations already have to hand, without a net-revenue allocation exercise behind it. A reader tracking FM-1 internally should expect this calculator's output to read differently, by design.
MGMA's own DataDive data covers this same metric, but the current figures sit inside a paid report and are not independently checkable from a public page. A specific day count is repeated across many revenue cycle vendor blogs with a link to MGMA's data reports index rather than a citable report title, so no MGMA day count appears in the band above. What MGMA has published on its own site is a relative finding, not an absolute one: its December 2021 Data Mine article on 2020 survey data found that Better Performer practices ran a median days-adjusted-FFS-charges-in-A/R figure 25 percent below the multispecialty median, with more than 70 percent of their A/R aged under 30 days against 8.1 percent aged past 120 days. That is a ratio between two groups of practices, not a day count this calculator can benchmark against, so it is offered here as context rather than as a threshold.
The cost-of-capital rate
The working capital figure below prices the receivable sitting above HFMA's 40-day ceiling at the annual rate you enter. There is no single published cost of capital for a healthcare provider: it depends on the organization's own line of credit, borrowing rate or internal hurdle rate. The default value on this page is a placeholder to get the tool usable on first load, not a benchmark, and the field is fully editable. Replace it with your own rate before taking the dollar figure anywhere.
How this differs from the denial rate benchmark
The denial rate benchmark calculator measures a different stage of the same cycle: what share of claims get denied on first submission. A practice can run a low denial rate and a slow collection cycle at the same time, because a clean claim can still sit unpaid for months once a payer has it. Days in A/R measures speed of collection regardless of denial outcome; the denial rate tool measures the outcome itself. Neither substitutes for the other, and a full revenue cycle picture needs both, alongside the reason-code and aging detail described in the revenue cycle automation and denial management use cases.
What it does not do
It does not break the receivable down by payer, aging bucket or reason code, which is where the actionable detail actually lives; a single organization-wide day count is a summary figure, not a diagnosis. It also does not adjust for seasonality in charge volume, which can move the average daily gross charges figure and, with it, the day count, even when nothing about collection performance has changed.

Questions we get asked
What is a good days in A/R benchmark?
HFMA publishes an ideal range of 30 to 40 days, calculated as total accounts receivable divided by average daily gross charges over the trailing 12 months. It is published as a range rather than a single figure because payer mix, specialty and claim volume all move the number, and a single decimal figure would claim a precision the underlying data does not support. Treat it as orientation, and treat your own trend over time, measured the same way each period, as the more useful signal.
Why does this calculator use gross charges instead of net patient service revenue?
Because that is the formula HFMA states in the article this calculator cites: current receivables divided by average daily gross charges. HFMA also publishes a related but different MAP Key, FM-1, Net Days in Accounts Receivable, which divides net A/R by average daily net patient service revenue instead. The two will not produce the same number on identical books, so mixing gross charges into one and net revenue into the other will read as a discrepancy that is not actually there.
How is this different from the denial rate benchmark calculator?
They measure different stages of the same cycle. The denial rate benchmark calculator checks what share of claims get denied on first submission. This tool checks how long an accepted claim takes to become cash, regardless of whether it was ever denied. A practice can have a healthy denial rate and a slow collection cycle at the same time, so neither figure substitutes for the other.
Where does the cost-of-capital rate come from?
From you. There is no single published cost of capital for a healthcare provider, since it depends on the organization's own borrowing rate, line-of-credit cost or internal hurdle rate. The default on this page exists only to make the tool usable on first load and is not a benchmark of any kind. Replace it with your own rate before treating the working capital cost figure as real.
Should total A/R be the full receivable or a figure net of write-offs?
The full outstanding receivable. A total that has already been reduced by write-offs or aged-off balances will understate days in A/R in a way that looks like good performance but is not, which is also the most common reason a practice sees a day count below HFMA's published range.
What does MGMA say about days in A/R?
MGMA's most recent DataDive figures for this metric sit inside a paid report and are not independently checkable from a public page, so no MGMA day count is built into the band this calculator uses. What MGMA has published on its own site is a relative finding from its Data Mine article on 2020 survey data: Better Performer practices ran a median days-adjusted-FFS-charges-in-A/R figure 25 percent below the multispecialty median. That is a ratio between two groups of practices, not an absolute day count, so it is offered as context in the methodology rather than as a threshold in the maths.
Why does the working capital cost only appear when I am above the range?
Because the gap it prices is the receivable sitting above HFMA's 40-day ceiling, and there is nothing to price when your days in A/R already sits at or below it. Sitting within or below the range does not mean the collection cycle is free of cost, only that this particular calculation, which measures the excess above a published ceiling, has nothing to add.
