Deductible vs Out-of-Pocket Maximum: What’s the Difference?

October 3, 2026 · Guides

Updated for the 2027 plan year (October 2026). Reflects the federal ACA cost-sharing limits effective January 1, 2027.

Deductible vs out of pocket maximum: the quick difference

These are the two most-confused terms in health insurance, and the difference is simple once you see it. Your deductible is the amount you pay for covered services before your plan begins to chip in. Your out-of-pocket maximum is the ceiling — the most you can be required to pay in a plan year for covered, in-network care. After you reach it, the plan covers 100% of covered costs for the rest of the year.

Think of the deductible as the start line and the out-of-pocket maximum as the finish line. Everything you spend on covered care — your deductible, plus any copays and coinsurance — counts toward that finish line. The out-of-pocket maximum is always higher than the deductible (or, on some plans, equal to it), because it includes the deductible plus the cost-sharing you pay afterward. Premiums never count toward either number.

Deductible vs out-of-pocket max: side-by-side comparison

The fastest way to see the difference between a deductible and an out-of-pocket maximum is to line them up. Both reset every plan year and both only count covered care, but they do opposite jobs: one decides when your plan starts paying, the other decides when you stop paying.

Official definitions for both terms are in the HealthCare.gov glossary: deductible and out-of-pocket maximum/limit.

What is a deductible?

A deductible is the fixed dollar amount you pay out of your own pocket for covered services each year before your insurance starts paying its share. Whatever your deductible is — on many plans it runs to a few thousand dollars — you pay that full amount for covered care yourself before the plan shares the cost. Until you reach it, you are responsible for the full negotiated cost of most services.

Deductibles reset at the start of each plan year, so spending does not carry over. Not every service waits behind the deductible, though. Under the Affordable Care Act, preventive care — annual check-ups, recommended screenings, and vaccines — is covered at no cost even before you meet your deductible. Many plans also apply flat copays to things like primary-care visits or generic drugs from day one.

What is an out-of-pocket maximum?

Your out-of-pocket maximum (sometimes called the out-of-pocket limit) is the most you will ever pay for covered, in-network care in a single plan year. It bundles together your deductible, your coinsurance, and your copays. Once those payments add up to the limit, your insurer pays 100% of covered services for the rest of the year — you pay nothing more.

This cap is the real financial protection in a health plan. It is what stops a serious illness or accident from turning into unlimited medical bills. Even a plan with a high deductible is protecting you, because the out-of-pocket maximum puts a hard ceiling on your total exposure. Knowing this number matters more than almost any other figure when you choose a health plan.

Where copays and coinsurance fit in between

Copays and coinsurance are the two forms of cost-sharing that sit between the deductible and the out-of-pocket maximum. They are how you and your plan split the bill after you’ve met your deductible.

Copay

A copay is a flat fee for a specific service — say a set fee for a doctor’s visit and a smaller one for a generic prescription. It doesn’t change with the size of the bill. Some copays apply before you meet your deductible; others kick in afterward, depending on the plan.

Coinsurance

Coinsurance is a percentage of the cost you pay after meeting your deductible. With 20% coinsurance, you pay 20% of a covered service and your plan pays the other 80%. Your share is one-fifth of the allowed amount for every covered service, so a bigger bill means a bigger share. Coinsurance continues until your payments reach the out-of-pocket maximum.

Both copays and coinsurance count toward your out-of-pocket maximum. They are the middle stretch of the race — the payments you make between the start line (deductible) and the finish line (out-of-pocket max).

The order your money flows through a health plan

Here is the sequence every dollar follows in a typical plan, from the first payment to full coverage. Seeing it in order makes the whole system click.

1. Premium. You pay this every month just to keep the plan active. It never counts toward your deductible or out-of-pocket maximum.
2. Deductible. You pay the full negotiated cost of covered services until you reach your deductible amount.
3. Coinsurance and copays. After the deductible, you and your plan share costs — you pay a percentage (coinsurance) or a flat fee (copay) while the plan pays the rest.
4. Out-of-pocket maximum. Your deductible, coinsurance, and copays add up here. When they hit the limit, you stop paying.
5. Plan pays 100%. For the rest of the plan year, your insurer covers all covered, in-network care. You owe nothing more except your monthly premium.

That last point is the payoff: premium keeps flowing, but your cost-sharing stops entirely. If you want the full picture of how these pieces connect, our guide to how health insurance works walks through each stage with examples.

What counts toward your deductible and out-of-pocket maximum

Not every dollar you spend on health care counts toward these limits. The rule of thumb: payments for covered, in-network services count; almost everything else does not. The biggest surprise for most people is that premiums never count toward your out-of-pocket maximum, even though they’re your largest health expense.

What counts toward your deductible is narrower: only your own payments for covered services that are subject to the deductible. Copays that your plan applies outside the deductible may skip it but still count toward the out-of-pocket maximum. Because the rules vary by plan, always read the Summary of Benefits and Coverage before you enroll. You can look up any term in the official glossary at HealthCare.gov.

Family plans: embedded vs aggregate deductibles

When you cover more than one person, deductibles and out-of-pocket maximums work in one of two ways. Knowing which your plan uses can change your costs by thousands of dollars.

Embedded deductible

With an embedded deductible, each family member has their own individual deductible inside the larger family deductible. If one person hits their individual limit, the plan starts covering that person’s care even if the whole family hasn’t met the family deductible yet. This protects any single member who gets sick.

Aggregate deductible

With an aggregate deductible, there is one combined family amount. The plan pays nothing until the family’s total spending reaches the full family deductible — it doesn’t matter whether that comes from one person or several. Aggregate deductibles are common on some high-deductible health plans (HDHPs) that pair with a Health Savings Account.

The same logic applies to the family out-of-pocket maximum. Under the ACA, no single person’s spending can exceed the individual out-of-pocket maximum, even on a family plan — an important embedded protection that applies across the board.

2027 out-of-pocket maximum limits under the ACA

Marketplace and most job-based plans can’t set an out-of-pocket maximum higher than the federal cap. For the 2027 plan year, the Affordable Care Act limits in-network cost-sharing to $12,000 for an individual and $24,000 for a family — up from $10,600 and $21,200 in 2026. Your plan may set a lower limit — many do — but it cannot go above these figures for essential health benefits.

These caps are why even a bare-bones Bronze plan still protects you from catastrophe. A Bronze plan covers about 60% of average costs, Silver about 70%, Gold about 80%, and Platinum about 90%; generally, the more a plan pays, the lower your deductible and out-of-pocket maximum. The federal limits are updated each year and published by the Centers for Medicare & Medicaid Services at CMS.gov. Comparing where each plan sets its cap is a core step in shopping the Health Insurance Marketplace.

A worked example: one year of care

Walking through a year step by step makes this concrete. Imagine a plan with a deductible of a few thousand dollars, 20% coinsurance, a flat primary-care copay, and an out-of-pocket maximum at or below the 2027 federal cap of $12,000. Here’s how one person’s spending plays out across a year of care, in the order the bills arrive.

Trace the flow: the preventive physical costs nothing, and the copay is a small flat fee. The person then pays the full negotiated cost of the MRI and specialist until the deductible is met. After that, the person pays 20% coinsurance on the surgery and therapy. Those payments push the running total — deductible plus copay plus coinsurance — up to the out-of-pocket maximum, and from that point on, the plan covers everything. The copay and coinsurance counted toward the cap; the premium (paid separately each month) did not.

Notice how the out-of-pocket maximum did the heavy lifting. A year like this can easily produce tens of thousands of dollars in billed care, but the person’s own share stopped at the plan’s out-of-pocket maximum — never more than $12,000 for in-network care on a 2027 individual plan, and often less. That ceiling is the single most important protection in any plan, which is why it belongs at the center of every comparison when you look for affordable health insurance.

The 2027 cap in action: a deductible vs out-of-pocket example

Here is the out-of-pocket maximum at work with a big bill, using only the official 2027 limit. Say you have an individual 2027 plan whose out-of-pocket maximum is set at the federal cap of $12,000, and a hospital stay is billed at many times that amount.

1. Deductible first. You pay the negotiated cost of covered care until your deductible is met.
2. Then coinsurance or copays. You pay your share of each covered bill; the plan pays the rest.
3. Then the stop. The moment your deductible, copays and coinsurance add up to $12,000, you stop paying for covered, in-network care for the rest of 2027. Every covered bill after that is the plan’s.

On a family plan the 2027 cap is $24,000 for the household, but no one person can be charged more than the $12,000 individual limit. Your own plan’s limits may be lower; check its Summary of Benefits and Coverage. The deductible decides how fast you start getting help. The out-of-pocket maximum decides the worst case.

Deductible vs out-of-pocket max: which matters more?

If you rarely use care, the deductible matters less than you think, because preventive care is covered before it and many plans charge flat copays for office visits. If you expect surgery, a pregnancy, a chronic condition or ongoing prescriptions, the out-of-pocket maximum matters most, because you are likely to reach it.

• Healthy, low use: compare premiums first, then make sure you could cover the deductible from savings if something happened.
• Moderate use: look at copays and coinsurance for the services you actually use, plus the deductible.
• High or planned use: add the yearly premium to the out-of-pocket maximum. That sum is your realistic worst-case cost for the year, and it is the fairest way to compare plans.
• Income up to 250% of poverty: check Silver plans with cost-sharing reductions, which lower both the deductible and the out-of-pocket maximum.

Whichever group you are in, look at both numbers together. A low deductible paired with a high out-of-pocket maximum can still leave you exposed, and a high deductible is easier to live with when the cap behind it is low.
