What this calculator shows
Appeals cost real work: records, letters, payer calls and follow-up. The appeal success rate tells you whether that work is aimed at denials that can actually be overturned. It needs two counts for the same period: appeals submitted, and appeals that ended overturned or paid.
Count an appeal as submitted when it leaves your office, and as successful when the payer reverses and pays any part of the claim. Pending appeals muddy the rate, so use a period old enough that most appeals have answers.

Appeal Success Rate Calculator
Of the appeals you send, how many actually overturn the denial?
How the calculation works
Appeal success rate = appeals overturned / appeals submitted x 100. Unsuccessful or pending = submitted minus overturned.
How to read your result
A low rate usually means one of two things: appeals are being sent on denials that were never payable, or appeals are missing the documentation the payer asked for. Tracking the rate by denial reason separates those. Our guide to appealing a denied claim covers the evidence packet, and denial management includes appeal selection, which is where this rate is won.

Before you rely on the number
Results are estimates for educational and operational planning, built from the figures you enter. They are not guarantees of reimbursement, savings or recovery, and they do not replace a review of your own claims, contracts and remittances. Do not enter patient-identifiable or protected health information: this calculator runs in your browser and nothing you type is stored or sent anywhere.
FAQ
Calculator questions
Still have a question? Talk to our team about your billing workflow.
Should corrected claims count as appeals?
No. A corrected claim fixes an error on your side; an appeal asks the payer to reverse a decision. Counting them together flatters the rate and hides error patterns.
What about appeals still waiting for an answer?
Either exclude very recent appeals or accept that the rate understates success until answers arrive. Be consistent month to month.
Is a higher rate always better?
Mostly, but a rate near 100% can also mean your team only appeals sure things and leaves recoverable denials unworked. Read it with the unworked-denial share in the revenue leak calculator.
