How this calculator works
Estimated covered amount = min(item cost, allowance) x reimbursement percent. Estimated out-of-pocket = item cost + copay - estimated covered amount.
Estimated out-of-pocket = item cost + copay - (min(item cost, benefit allowance) x reimbursement percent).
Inputs explained
Dates and timing
Use dates from the claim, service record, authorization request, EOB, or payer portal.
Dollar amounts
Use allowed amounts, estimates, remaining benefits, or reimbursement assumptions from your records.
Plan assumptions
Enter deductible, coinsurance, maximum, allowance, or delay assumptions exactly as you want modeled.
Understanding your results
Treat the output as operational planning math, not a final insurance determination. Real reimbursement, eligibility, deadlines, exclusions, coordination of benefits, and appeal rights depend on the governing plan and payer.
Example scenarios
Practical example
For $320 glasses, a $180 allowance, 100% reimbursement on the allowance, and a $20 copay, the estimated out-of-pocket amount is $160.
