Deductible vs Out-of-Pocket Maximum - What Each Cap Means

Two caps show up on almost every US health plan Summary of Benefits: the deductible and the out-of-pocket maximum. They are related, but they are not the same number and they do not count the same dollars.

Deductible

The deductible is what you generally pay toward covered services before the plan starts sharing costs through coinsurance. Copays sometimes skip the deductible; premiums almost never count. Use the deductible calculator for one bill, or the deductible remaining tool for year-to-date progress.

Out-of-pocket maximum

The OOP max is usually the larger umbrella: after you hit it on eligible in-network cost sharing, the plan pays 100% of covered in-network care for the rest of the plan year. Premiums still do not count. Track room left with the out-of-pocket max calculator.

Where coinsurance fits

After deductible, many plans split remaining allowed amounts with coinsurance (for example 20% you / 80% plan) until you reach the OOP max. The coinsurance calculator models one bill; it does not replace reading your SBC.

What this guide is not

Not insurance advice. Embedded family deductibles, separate out-of-network OOP limits, and pharmacy tiers can change what applies to you — trust the plan documents when they disagree with a calculator.
