Most people know health insurance has a deductible. Fewer understand that there’s a second number — the out-of-pocket maximum — that acts as a ceiling on everything you can be charged in a year. Here is how it stacks.
Layer 1: Premium
Paid every month regardless of care used. Does not count toward your OOP max.
Layer 2: Deductible
First dollars of covered care come out of your pocket. Counts toward OOP max.
Layer 3: Coinsurance / Copays
Your share after the deductible. Counts toward OOP max.
Layer 4: Out-of-Pocket Maximum
Once deductible + coinsurance + copays hit this number, the plan pays 100% for the rest of the year. In 2026: $9,450 individual / $18,900 family (federal cap).
What Is an Out-of-Pocket Maximum?
The out-of-pocket maximum (also called the out-of-pocket limit) is the most you will pay for covered in-network health care services in a single plan year. Once you reach this amount, your insurance pays 100% of covered costs for the remainder of the plan year.
In 2026, the ACA sets federal out-of-pocket maximum limits at $9,450 for an individual and $18,900 for a family. No ACA-compliant plan can require you to pay more than these amounts for covered in-network services.
What Counts Toward Your Out-of-Pocket Maximum?
Three types of cost-sharing count toward your out-of-pocket maximum:
- Deductibles — amounts you pay before insurance starts sharing costs
- Copays — fixed-dollar amounts for covered services
- Coinsurance — your percentage share after meeting the deductible
What does not count toward the out-of-pocket maximum:
- Monthly premiums — your premium never counts toward the OOP max
- Out-of-network costs — most plans have a separate (higher) OOP max for out-of-network care, or none at all for HMOs
- Services not covered by the plan — if your plan does not cover a service, what you pay for it does not accumulate toward the limit
- Amounts above the allowed amount for balance-billed services — if a provider bills above what your plan allows and you are balance-billed, those excess amounts may not count
Individual vs. Family Out-of-Pocket Maximums
Family plans have both an individual embedded OOP max and a family aggregate OOP max. The individual limit protects any single family member from accumulating more than $9,450 in a year. The family aggregate means the family collectively cannot pay more than $18,900 regardless of how those costs are distributed among members.
Example: a family of four has a $18,900 family OOP max with $9,450 embedded individual limits. If one child has an illness that generates $9,450 in cost-sharing, that child's costs stop there (the insurer pays 100% for that child from then on), even if the family aggregate has not been reached. This embedded design protects against a single catastrophic year concentrating all costs on one family member.
When Is the Out-of-Pocket Maximum Most Important?
The OOP maximum matters most when you have a serious illness, major surgery, or hospitalization. If you are generally healthy and rarely use care, you may never reach your deductible, let alone your OOP max. But if you face a cancer diagnosis, major accident, or chronic illness requiring ongoing treatment, the OOP max is the number that determines your worst-case annual exposure.
When comparing plans, look at both the OOP max and the deductible together. A plan with a $6,000 deductible and a $6,000 OOP max means after you hit the deductible, the plan pays everything. A plan with a $3,000 deductible and a $9,000 OOP max means you could pay up to $9,000 before the plan covers 100%.
Silver Plans with Cost-Sharing Reductions
If your household income is between 100% and 250% of the Federal Poverty Level, you may qualify for a Silver plan with Cost-Sharing Reductions (CSRs). These enhanced Silver plans have dramatically lower out-of-pocket maximums — in some cases as low as $1,500 for individuals — at little or no additional premium. This is one of the most underutilized benefits in the marketplace.
Out-of-Pocket Maximum vs. Deductible: A Quick Summary
- Deductible: What you pay before cost-sharing begins (insurance starts paying its share)
- Coinsurance/copays: Your share of costs after the deductible
- Out-of-pocket maximum: The ceiling on everything above combined; once hit, your plan pays 100%
All three work together: the deductible is the entry point, coinsurance/copays fill the middle, and the OOP max is the safety net.
