About this calculator
A denial rate that sounds manageable — say 8% — can quietly cost a mid-size practice hundreds of thousands of dollars a year once you account for claims that are never successfully appealed and the staff time burned reworking the ones that are. This calculator takes your monthly claims volume, average claim value, denial rate, and recovery rate on appeal to show net revenue lost, plus the labor cost of the rework itself, since appeals typically take 20-45 minutes of biller time each. Industry benchmarks put a 'clean' denial rate below 5%, with well-run practices closer to 2-4%; anything above 10% signals a front-end problem (eligibility verification, coding, prior auth gaps) rather than a back-end appeals problem. Reducing the denial rate at the source is almost always cheaper than getting better at appeals.
Worked example
Using the values the calculator loads with:
Inputs
- Claims submitted per month: 1200
- Average claim value: 165 $
- Denial rate: 9 %
- % of denials successfully overturned: 55 %
- Staff minutes per appeal: 30
- Biller loaded hourly cost: 28 $
Results
- Total annual cost of denials: $114,372
- Net revenue lost monthly: $8,019
- Monthly staff rework cost: $1,512
- Total monthly cost: $9,531
- Denied claims per month: 108
What each field means

- Denial rate (%)
- The denial rate used in the calculation, measured in %. Starts at 9 % so you have a working example on load. Accepted range: 0–100 %.
- % of denials successfully overturned (%)
- The % of denials successfully overturned used in the calculation, measured in %. Starts at 55 % so you have a working example on load. Accepted range: 0–100 %.
- Staff minutes per appeal
- The staff minutes per appeal used in the calculation. Starts at 30 so you have a working example on load.
- Biller loaded hourly cost ($)
- The biller loaded hourly cost used in the calculation, measured in $. Starts at 28 $ so you have a working example on load.

FAQ
What's a good benchmark denial rate?
Under 5% is considered clean by MGMA and HFMA benchmarks; top-quartile practices run 2-4%. Above 10% usually points to a systemic issue in eligibility verification, prior authorization, or coding accuracy rather than random payer behavior, and is worth a root-cause audit before investing more in appeals staff.
What are the most common denial reasons worth fixing first?
Eligibility/coverage issues, missing prior authorization, and coding errors (wrong modifier, mismatched diagnosis-procedure pairing) account for the majority of denials at most practices. These are all preventable at the front end and cheaper to fix there than to appeal after the fact.
Is it worth appealing every denial?
Not always — a $40 claim denial might cost more in staff time to appeal than it recovers. Set a dollar threshold (many practices use $75-$100) below which claims are written off rather than appealed, and focus appeal effort on high-value or recurring denial patterns.
How much does denial management software typically cost, and is it worth it?
Clearinghouse-level denial analytics tools run roughly $200-$1,500/month depending on practice size. If your calculated annual denial cost exceeds $50,000, this software usually pays for itself by catching denial patterns faster than manual review.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
