Most practices don’t realize how much revenue is slipping through the cracks until they actually break down their numbers.
This calculator estimates how much revenue your practice may be losing each month based on a few key billing performance indicators:
- claim denials
- collection efficiency
- and how quickly you’re getting paid
You don’t need perfect data to use it — even rough estimates can reveal whether there are meaningful issues in your billing.
What This Calculator Measures
The results are based on how your current billing performance compares to healthy benchmarks across three core areas:
- Denial Rate — how often claims are rejected or denied
- Net Collection Rate — how much of your allowed revenue you actually collect
- A/R Days — how long it takes to get paid
If any of these are outside benchmark ranges, there’s a high likelihood your practice is losing revenue every month.
What You'll Need To Know (and How To Find It)
Monthly Collections
What it is:
The total amount your practice collects in a typical month.
How to find it:
- Pull from your billing reports or practice management system
- Look at total payments received over the last 30–90 days and average it
Tip:
If you’re unsure, use your best estimate — the goal is to identify potential gaps, not calculate an exact audit.
Denial Rate (%)
What it is:
The percentage of claims that are denied or rejected.
Healthy Optimal benchmark:
Under 5%
How to find it:
- Check your clearinghouse reports
- Look at total claims submitted vs denied
Quick formula:
Denied Claims ÷ Total Claims Submitted × 100
Net Collection Rate (%)
What it is:
The percentage of allowed revenue your practice actually collects.
Healthy Optimal benchmark:
95% – 99%
How to find it:
- Look at your billing or financial reports
Quick formula:
Payments Collected ÷ Allowed Amount × 100
Why it matters:
This is one of the clearest indicators of revenue leakage from underpayments, write-offs, or missed follow-up.
A/R Days
What it is:
The average number of days it takes to collect payment after services are rendered.
Healthy Optimal benchmark:
Under 35 days
Warning sign: 45+ days
How to find it:
- Check your A/R aging report
- Many billing systems calculate this automatically
Why it matters:
Long A/R cycles often point to slow follow-up, claim issues, or process breakdowns.
What Your Results Mean
After entering your numbers, you’ll see an estimate of:
👉 How much revenue may be at risk each month
👉 Where your billing performance may be breaking down
This isn’t a full audit — but it’s often enough to quickly identify whether your billing is performing where it should be, or if there are issues worth addressing.
Don’t Know Your Numbers?
That’s normal.
Many practices don’t have clear visibility into these metrics — which is often part of the problem.
👉 Use your best estimate and continue through the calculator.
Even approximate numbers can reveal whether your billing performance is likely costing you revenue.
