Two numbers do more than anything else to decide what you'll pay for health care in a year: your deductible and your out-of-pocket maximum. They sound similar, but they do very different jobs, and mixing them up is one of the most common reasons people pick the wrong plan.
Here's a plain-English explanation, followed by real-dollar examples.
The short answer
- Deductible: the amount you pay for covered care before your plan starts sharing costs.
- Out-of-pocket maximum: the most you'll pay for covered in-network care in a plan year. Once you hit it, your plan pays 100%.
Think of the deductible as the starting line for cost sharing, and the out-of-pocket maximum as the finish line that protects you from huge bills.
The terms you need to know
| Term | What it means |
|---|---|
| Premium | What you pay every month to have insurance, whether you use it or not |
| Deductible | What you pay for covered care before the plan starts paying its share |
| Copay | A flat fee for a service, like $30 for a doctor visit |
| Coinsurance | Your percentage of the cost after the deductible, like 20% |
| Out-of-pocket maximum | Your yearly cap on deductibles, copays and coinsurance for covered in-network care |
How they work together, step by step
- Before you meet your deductible, you generally pay the full negotiated price for most services. (Many plans cover preventive care, like annual checkups and screenings, at no cost even before the deductible. Some also offer copays for office visits or generic drugs before the deductible.)
- After you meet your deductible, you and your plan share costs through coinsurance or copays.
- Once your total spending reaches the out-of-pocket maximum, your plan pays 100% of covered in-network care for the rest of the plan year.
Does the deductible count toward the out-of-pocket maximum?
Yes. What you pay toward your deductible, plus your copays and coinsurance, all count toward your out-of-pocket maximum.
What doesn't count:
- Your monthly premiums
- Care your plan doesn't cover
- Usually, out-of-network care (unless your plan says otherwise)
- Amounts an out-of-network provider bills above what your plan allows
Three real-dollar examples
Let's use a sample plan with:
- Deductible: $3,000
- Coinsurance: 20% after the deductible
- Out-of-pocket maximum: $7,000
Example 1: A light year ($800 in care)
You have a few sick visits and a lab test totaling $800. You haven't met your deductible, so you pay the full $800. Your plan pays $0 (beyond any free preventive care).
Example 2: A minor surgery ($20,000 in care)
- You pay the first $3,000 (your deductible).
- The remaining $17,000 is split: you pay 20%, or $3,400.
- Your total: $6,400. Your plan pays $13,600.
Example 3: A major hospital stay ($50,000 in care)
- Deductible: $3,000.
- 20% of the remaining $47,000 would be $9,400, for a total of $12,400.
- But your out-of-pocket maximum is $7,000, so that's all you pay.
- Your total: $7,000. Your plan pays the remaining $43,000.
That last example is why the out-of-pocket maximum matters so much. It's your real worst-case number for the year (not counting premiums).
How family plans work
Family plans usually have both an individual and a family deductible and out-of-pocket maximum.
- Once one person meets the individual amount, the plan starts sharing costs for that person.
- Once the family's combined spending meets the family amount, it applies to everyone.
Under ACA rules, no single person on a family plan has to pay more than the individual out-of-pocket limit.
2027 out-of-pocket limits
For 2027 plans, federal rules cap out-of-pocket maximums at $12,000 for an individual and $24,000 for a family for in-network care. Many plans set lower limits.
Which plan is right for you: low deductible or low premium?
- Expect little care? A plan with a lower premium and higher deductible may save you money, as long as you could afford the out-of-pocket maximum in a bad year.
- Expect regular care, ongoing prescriptions or a planned procedure? A plan with a higher premium but lower deductible and out-of-pocket maximum may cost less overall.
- Have savings and want tax breaks? An HSA-eligible high-deductible plan lets you save pre-tax money for medical costs.
A simple test: add up a plan's yearly premiums plus its out-of-pocket maximum. That's your worst-case total cost. Compare that across plans along with your expected care. Our Open Enrollment checklist walks through the rest of the comparison.

Frequently asked questions
What's the difference between a deductible and an out-of-pocket maximum?
The deductible is what you pay before your plan starts sharing costs. The out-of-pocket maximum is the most you'll pay in a year for covered in-network care. After you reach it, your plan pays 100%.
Do premiums count toward the out-of-pocket maximum?
No. Monthly premiums never count toward your deductible or out-of-pocket maximum.
Is it better to have a low deductible or a low out-of-pocket maximum?
It depends on how much care you expect. A low out-of-pocket maximum limits your worst-case cost. A low deductible matters most if you expect to use care regularly.
Does the out-of-pocket maximum reset every year?
Yes. It resets at the start of each plan year, along with your deductible.
What happens after I reach my out-of-pocket maximum?
Your plan pays 100% of covered, in-network services for the rest of the plan year. You still pay your monthly premiums.
