Deductible vs out-of-pocket maximum: what you actually pay in a year

The confusion is understandable. Both numbers are annual, both reset with the plan year, and both are described as "what you pay before the plan pays." They answer different questions, though. The deductible answers when the plan starts sharing your costs. The out-of-pocket maximum answers when your share stops. Everything you pay in between is coinsurance and copays, and in the procedure and hospital years worked below, that middle stretch is the largest piece.

An invented plan and three invented years of medical spending make the arithmetic concrete, followed by the costs that never count toward either number. The federal limits come from HealthCare.gov and the regulation behind them, checked October 22, 2026. Your own plan's numbers are in its Summary of Benefits and Coverage; use those, not the examples, for any real decision. This is cost arithmetic, not insurance or legal advice, and not a recommendation of any plan.

Four plan numbers, and the order they apply in

Every year of costs under a typical plan runs through the same sequence. Write your plan's four numbers down before doing anything else.

Definitions: HealthCare.gov glossary entries for deductible, coinsurance, allowed amount and out-of-pocket maximum, checked October 22, 2026. The fifth number on your plan, the premium, sits outside this table on purpose. It is the price of having the plan, paid monthly whether or not you use care, and it never counts toward the deductible or the maximum.

Notice the phrase "allowed amount" in the first two rows. HealthCare.gov defines it as the maximum amount a plan will pay for a covered service, sometimes called the negotiated rate. Your deductible and coinsurance are figured on that amount, not on the provider's full billed charge. A hospital line showing $4,000 in charges might have an allowed amount of $1,600, and your share is figured on the $1,600. That single distinction explains most of the difference between a bill's headline number and what an in-network patient owes. To turn these numbers into an estimate for one procedure, layer by layer, see how to estimate your cost with insurance.

The federal ceiling on the maximum

Plans choose their own out-of-pocket maximum, but federal law sets the highest one a plan may use. For Marketplace plans, HealthCare.gov lists the limits as follows.

The regulation behind those numbers, 45 CFR 156.130, sets the self-only limit and makes the limit for other coverage twice the self-only figure, which is why each family figure is exactly double. It also contains the rule that matters most for surprise bills: a plan that uses a provider network is not required to count cost sharing for out-of-network care toward the annual limit.

From 2026 to 2027 the individual ceiling rises by $1,400. That does not mean your plan's maximum will rise by that much, or at all; it means plans may set it up to the new ceiling. During open enrollment, compare the maximum each plan actually lists, which is often well below the ceiling.

Three invented years under one invented plan

The plan below is hypothetical, built only to show the arithmetic: a $3,000 deductible, 20% coinsurance after the deductible, a $40 copay for primary care visits that does not apply to the deductible, a $7,000 in-network out-of-pocket maximum, and a premium of $450 a month. The spending in each year is the total of the plan's allowed amounts for covered, in-network care, not billed charges. None of these are prices for real services.

Year one: a light year, $1,200 of allowed amounts plus four visits

Four primary care visits cost $40 each in copays, $160 in all. Separately, $1,200 of lab work and imaging is applied to the deductible, and you pay all of it, because the deductible has not been met. Out of pocket for care: $1,360. Premiums: $5,400. Total cost of the year: $6,760. The plan paid little beyond the visits, and the premium was most of your cost.

Year two: a procedure year, $15,000 of allowed amounts

You pay the first $3,000 as deductible. The remaining $12,000 is shared: 20% is $2,400 for you and $9,600 for the plan. Add four visit copays of $160. Out of pocket for care: $5,560, still below the $7,000 maximum. Premiums: $5,400. Total: $10,960. This is the year people mean when they say they met their deductible in March and kept getting bills. They did, and the bills were coinsurance.

Year three: a hospital year, $60,000 of allowed amounts

The deductible is $3,000. Coinsurance on the remaining $57,000 would be $11,400, but the maximum stops it. Your deductible plus coinsurance plus copays cannot pass $7,000 for covered in-network care. Out of pocket for care: $7,000. Premiums: $5,400. Total: $12,400. Everything above the maximum, for in-network covered services, the plan pays in full until the plan year ends.

The table carries the lesson in its last two columns. Between a light year and a hospital year, the allowed amounts rise fiftyfold, but the year total does not quite double, because the maximum caps the care column and the premium is constant. The worst case for covered in-network care under any plan is the out-of-pocket maximum plus twelve months of premium. That sum is the single most useful number for comparing plans, and our guide to Marketplace plan costs for 2027 uses it with the premium tax credit applied.

Comparing two plans with the same three years

The two numbers become a decision tool when you run the same years through a second plan. Add a hypothetical Plan B with a $6,000 deductible, the same 20% coinsurance and $40 visit copay, a $9,000 out-of-pocket maximum, and a lower premium of $300 a month. The original plan becomes Plan A.

Plan B's procedure year works out as the $6,000 deductible, plus 20% of the remaining $9,000, which is $1,800, plus $160 in copays: $7,960, still under its $9,000 maximum. In the hospital year it stops at the maximum.

Read the result as a range, not a winner. In a light year the lower premium saves $1,800. In a heavy year the higher deductible and maximum cost a few hundred dollars more. The spread between best and worst year is $5,640 for Plan A and $7,640 for Plan B, so Plan B carries more risk in exchange for lower fixed cost. Which trade fits a household depends on its expected care and how much of a bad year it could absorb, and that judgment stays with the household. The arithmetic only makes the trade visible. Two cautions keep the comparison honest: both plans must include the providers and drugs you expect to use in network, and the worst case for each is its maximum plus its premiums, only for covered in-network care.

Where you hit the deductible and where you hit the maximum: a timeline

The same procedure-year example, spread across months, shows why a deductible feels like a wall and the maximum feels like a finish line. Assume, hypothetically, $2,000 of allowed amounts in February, a $10,000 outpatient procedure in April, and $3,000 of follow-up care spread over the summer.

• February: you pay all $2,000, because it is all deductible. Running total $2,000.
• April: the first $1,000 of the procedure finishes the deductible. Coinsurance applies to the other $9,000, so you owe $1,800 more. Running total $4,800.
• Summer: 20% of $3,000 is $600. Running total $5,400, plus the visit copays.

The deductible was met in April, yet the largest single bill arrived in April too. That pattern is common, and it is why a planned procedure is worth pricing in writing beforehand even for an insured patient. The questions to ask billing before a procedure include asking the plan or provider for your estimated share, which depends on where you are in the deductible when the claim is processed.

The costs that never count toward either number

HealthCare.gov lists four categories of spending that do not count toward the out-of-pocket maximum. Each one is a way for a real year to cost more than the table above suggests.

Premiums

Covered above. Premiums are never cost sharing. A plan with a low maximum and a high premium can cost more in a healthy year than a plan with a higher maximum and a low premium.

Services the plan does not cover

Anything excluded from your plan's benefits is not cost sharing, so it counts toward nothing. Before an elective service, ask the plan in writing whether it is covered and whether prior authorization is needed. A service later denied as not covered lands entirely on you. A missing prior authorization can also turn a covered service into a denied claim; see prior authorization before a procedure.

Out-of-network care

Federal rules let network plans exclude out-of-network cost sharing from the annual limit. Some plans have a separate, higher out-of-network deductible and maximum; some cover out-of-network care only in emergencies. The federal No Surprises Act protects insured patients from out-of-network billing in emergencies and for certain care at in-network facilities, and the existing urgent care versus emergency room guide explains how those protections work. Outside those protections, out-of-network bills can sit entirely outside your maximum.

Charges above the allowed amount

When an out-of-network provider bills you for the difference between its charge and the plan's allowed amount, that is balance billing, and HealthCare.gov notes that a preferred, in-network provider may not balance bill you for covered services. The balance, where it is allowed, does not count toward the maximum.

Family plans: two deductibles and two limits

HealthCare.gov describes family plans as often having two kinds of deductible: an individual deductible that applies to each person and a family deductible that applies to everyone together. Out-of-pocket maximums work in parallel, with a per-person figure and a family figure. How the two interact depends on whether the plan is designed so that one person can reach their individual figure before the family reaches the family figure, sometimes called an embedded design. Plans differ on this, and it can change a family's year by thousands of dollars. Read the plan's Summary of Benefits and Coverage, or ask the plan in writing: "If one family member has a hospital stay, at what dollar amount does that person stop paying?"

A delivery is the plainest test of the family-plan question above, because a mother's claim and a newborn's claim arrive a few weeks apart on one policy. The birth-bill guide shows the same claims under a shared family deductible and under separate ones, and what each design adds to the family total.

The federal per-person cap inside non-grandfathered family plans

In a non-grandfathered family plan, whatever the plan calls its deductible design, one limit is embedded by federal rule. Starting with plan years in 2016, HHS clarified that the self-only annual limit on cost sharing applies to each individual, whether that person has self-only coverage or family coverage, and the Departments of Labor, HHS and the Treasury confirmed in their FAQs about Affordable Care Act Implementation, Part XXVII, that this covers every non-grandfathered group health plan, including self-insured and large employer plans and high deductible health plans. For 2027 the self-only limit is $12,000. So no one person on a non-grandfathered family plan can be made to pay more than $12,000 in cost sharing for covered in-network essential health benefits in a 2027 plan year, even if the plan's family maximum is higher and even if the plan says its deductible and maximum are "non-embedded."

The FAQ's own example shows how the two limits stack. A family of four has a family maximum of $13,000 in 2016. One member's cost sharing would have been $10,000, the other three $3,000 each. The first member's share stops at the 2016 self-only limit of $6,850, and the family's total stops at the plan's $13,000, with the plan paying the rest. The same arithmetic, moved to 2027 limits, is below.

Two members, two designs, two kinds of year

The plan is hypothetical: family coverage with a $6,000 family deductible, 20% coinsurance after the deductible, and a $17,000 family out-of-pocket maximum. In the embedded version, each person also has a $3,500 individual deductible; in the non-embedded version, only the family deductible exists. Neither version sets its own per-person maximum, so the federal $12,000 per-person cap applies. Member A's claims are processed first. Amounts are allowed amounts for covered in-network care.

Show who pays what

Year	Design	Member A pays	Member B pays	Family total
Moderate year	Embedded	$4,400	$1,500	$5,900
Moderate year	Non-embedded	$6,400	$300	$6,700
Hospital year	Embedded	$12,000	$1,500	$13,500
Hospital year	Non-embedded	$12,000	$300	$12,300

In the moderate year, the embedded design is cheaper by $800. Member A stops paying deductible at $3,500 and moves to coinsurance: $3,500 plus 20% of the other $4,500, or $4,400. Member B's $1,500 all falls inside the deductible, because the family has met only $3,500 of its $6,000. Under the non-embedded design, member A has to fill the whole $6,000 family deductible before coinsurance starts, paying $6,000 plus 20% of $2,000, or $6,400, but then member B pays only 20% of $1,500, which is $300.

In the hospital year, the ranking flips. Member A's deductible plus coinsurance would reach $20,800 under the embedded design and $22,800 under the non-embedded one, so the federal $12,000 cap decides member A's share in both. What is left is member B, and under the non-embedded design member B arrives after the family deductible is already full, so pays $300 instead of $1,500. Without the per-person rule, member A's share would have stopped only at the $17,000 family maximum, $5,000 more.

The lesson is not that one design is better. An embedded deductible helps when costs are spread out and nobody has a very large year; a non-embedded one can help the rest of the family once one person has a very large year, because that person fills the family deductible for everyone. The federal per-person cap protects the person with the large year either way. When you compare family plans, run your own household's likely claims through both designs the same way.

The extra test for family high deductible plans

High deductible health plans that pair with an HSA add one more rule. IRS Publication 969 says that when a family plan has both a family deductible and individual deductibles, the plan qualifies as an HDHP only if both are at least the minimum annual deductible for family coverage. For 2027 that minimum is $3,500 (IRS Revenue Procedure 2026-24), which is why the embedded deductible in the example above is exactly $3,500: a $2,000 individual deductible inside a $6,000 family deductible would disqualify the plan, and with it the family's HSA contributions. The same revenue procedure caps HDHP out-of-pocket costs at $8,700 for self-only and $17,400 for family coverage in 2027, so the example's $17,000 family maximum fits too. Our HSA and FSA guide covers the account side of that choice.

The three rows are separate limits that overlap. An HDHP has to satisfy both its own IRS cap and the HHS per-person rule; because the IRS self-only cap of $8,700 is lower than $12,000, a self-only HDHP will always sit under both.

Where the deductible rule has exceptions

• Preventive care before the deductible. HealthCare.gov says all Marketplace plans pay the full cost of certain preventive benefits even before you meet the deductible. A visit coded as diagnostic instead of preventive can carry cost sharing.
• Copays before the deductible. Many plans charge only a copay for primary care visits or generic drugs from day one, which still counts toward the maximum.
• High deductible plans paired with an HSA. These plans generally apply the deductible to most services before paying. Their own federal minimum deductibles and maximums are set by the IRS each year, explained in our HSA and FSA guide.
• Plan year versus calendar year. Marketplace plans run on the calendar year. Employer plans can use a different plan year, and both numbers reset on the plan's date, not January 1.

Using the two numbers before a planned procedure

If a procedure is on the calendar, the two numbers turn into a short estimate you can check against what the plan or provider tells you. You need four inputs: the allowed amount for the procedure (from your insurer's cost estimator or the provider's estimate), what you have already paid toward the deductible this year, your coinsurance rate, and what you have already paid toward the maximum. Then:

1. Deductible still owed = deductible minus what you have paid toward it, but not more than the allowed amount.
2. Coinsurance = rate times (allowed amount minus the deductible still owed).
3. Your estimated share = deductible still owed plus coinsurance, but not more than the maximum minus what you have paid toward it.

For an uninsured patient none of this applies, and the right route is the cash price and the Good Faith Estimate, explained in how to price a procedure without insurance. For an insured patient, the plan's own estimate is the figure to get in writing, and the arithmetic above is the way to check it. If the plan's figure and yours differ, ask which input the plan used.

The reset date and why it changes the arithmetic

Both numbers return to zero when the plan year starts again. For the hypothetical Plan A, a person who reached the $7,000 maximum in October pays nothing for covered in-network care in November and December, then starts again at the full $3,000 deductible in January. The same $10,000 outpatient procedure therefore costs that person $0 in December and about $4,400 in January under Plan A's terms: the $3,000 deductible plus 20% of the remaining $7,000. The timing of care is a clinical decision that belongs with you and your clinician; the cost side is only worth knowing so a January bill is not a surprise. Losing a job mid-year is the other way the counters can restart early, since a new policy keeps its own tallies; continuing the same plan under COBRA keeps the credit already earned, a rule set out with the premium math in our guide to how much COBRA costs per month.

What the plan's written answers fill in

A written answer to the last question is the insured patient's version of the confirm-in-writing rule this site applies to cash prices. Keep it with the procedure paperwork until the explanation of benefits arrives.

When the bill arrives

After a claim is processed, the plan sends an explanation of benefits showing the allowed amount, what was applied to your deductible, your coinsurance or copay, and your running totals toward the deductible and maximum. The provider's bill should not ask for more than the patient balance on that statement. Our guide to reading an explanation of benefits walks through each column, and the insurance cost guides collect the rest of the plan arithmetic on this site.

To turn these limits into a plan choice, the HDHP cost math guide compares a high deductible plan with a lower-deductible one at three spending levels, including the HSA tax saving.
