About Health Insurance Deductible & Out-of-Pocket Calculator

The Health Insurance Deductible & Out-of-Pocket Calculator computes exactly how much you pay vs. what your insurance covers for medical bills, modeling deductible satisfaction, coinsurance splits (e.g. 80/20), and out-of-pocket maximum caps.

Formula & Mathematical Calculation

Patient Responsibility = min( Out-of-Pocket Max, Deductible + ( Medical Bill - Deductible ) × Coinsurance Patient % )

Calculation Example

$15,000 Hospital Bill ($1,500 Deductible, 20% Coinsurance, $5,000 Out-of-Pocket Max): Patient pays $1,500 Deductible + 20% of remaining $13,500 ($2,700) = $4,200 Total Patient Cost (Insurance covers $10,800!).

Frequently Asked Questions

It applies your deductible to the medical bill first, then applies your coinsurance percentage to the remaining amount, and finally caps the total at your plan's out-of-pocket maximum. The patient responsibility shown is the lowest of the bill, the computed cost, and the cap.

The deductible is the amount you pay in full before your plan's coinsurance starts. The out-of-pocket maximum is the yearly ceiling on what you can be required to pay, after which your plan covers one hundred percent of covered services for that plan year.

Use covered, in-network medical expenses that your plan's coinsurance applies to. Deductible amounts, coinsurance rates, and out-of-pocket maximums differ by plan, and out-of-network care is typically not counted toward your plan's cap.

No. The calculator models only the deductible, coinsurance on the bill above the deductible, and the out-of-pocket cap. Fixed copays, prior authorizations, and out-of-network balances are separate and are not folded into this estimate.
