How this calculator works

Estimated refund due = max(0, Actual insurance payment - Expected payer payment - Prior refund or recoupment).
Estimated refund due = max(0, actual insurance payment - expected payer payment - prior refund or recoupment).

Inputs explained

Expected payer payment

The amount you expected the insurer to pay based on your EOB, contract, or claim review.

Actual insurance payment

The payment actually received from the insurer.

Prior refund or recoupment

Any amount already refunded, offset, or recouped for the same overpayment.

Understanding your results

A positive result suggests a possible remaining refund or overpayment amount. Validate against payer notices, EOBs, duplicate payments, and refund policies before acting.

Example scenarios

Duplicate payment review

$1,050 actual payment against $900 expected payment creates a $150 potential overpayment. If $50 was already recouped, the estimated refund remaining is $100.

Key Features

Tips & Best Practices

  • Check for duplicate checks, corrected claims, and secondary payer activity.
  • Document payer correspondence before issuing or disputing a refund.
  • Track prior recoupments so the same amount is not refunded twice.

Frequently Asked Questions

Does this decide whether a refund is legally required?
No. It only estimates a possible overpayment from your entered amounts. Verify payer policy, contract terms, and applicable rules.
Can I account for a prior recoupment?
Yes. Enter any prior refund or recoupment already applied to reduce the estimated remaining refund.
Are payment values stored?
No. The calculation runs locally from the values you enter.
