Out-of-Pocket Maximum Calculator
Calculate your expected out-of-pocket costs based on planned medical procedures, deductible, coinsurance, and OOP maximum.
About this calculator
The Out-of-Pocket Maximum Calculator projects what you'll actually pay out of pocket for a year of planned medical care, given your plan's deductible, coinsurance rate, and out-of-pocket maximum. Below the deductible, you pay the full cost of care; between the deductible and the out-of-pocket maximum, you pay your coinsurance share of each additional dollar; past the out-of-pocket maximum, the plan covers 100% of further costs for the rest of the plan year. Planned Procedure Costs moves Expected Out-of-Pocket directly until the out-of-pocket maximum is reached, at which point additional procedure costs stop increasing what you owe entirely -- the calculator saturates there by design, since that's exactly what an out-of-pocket maximum is supposed to guarantee.
Monthly Premium never enters the Expected Out-of-Pocket calculation at all -- premiums and out-of-pocket medical costs are tracked separately, then summed into Total Annual Health Cost, so raising your premium (say, by choosing a richer plan) doesn't itself lower or raise what you'd owe for a given year of claims; only the plan's deductible, coinsurance, and out-of-pocket maximum determine that. For the 2026 plan year, HealthCare.gov states the ACA marketplace out-of-pocket limit can't be more than $10,600 for self-only coverage and $21,200 for family coverage -- your specific plan's limit may be set lower than that federal ceiling, so check your plan documents rather than assuming the federal maximum applies to you.

How to Use This Calculator
- Enter your plan's annual deductible.
- Enter your plan's coinsurance percentage after the deductible.
- Enter the plan's out-of-pocket maximum.
- Input your expected annual medical claims to see your projected cost.
- Review at what spending level your out-of-pocket cap kicks in to fully protect you.
How the result changes with Annual Deductible
| Annual Deductible | Expected Out-of-Pocket | Total Annual Health Cost |
|---|---|---|
| $1,500.00 | $3,340.00 | $8,740.00 |
| $2,250.00 | $3,940.00 | $9,340.00 |
| $4,500.00 | $5,740.00 | $11,140.00 |
| $7,500.00 | $8,140.00 | $13,540.00 |
What each input means
- Annual Deductible
- Your plan's annual deductible before insurance starts paying.
- Your Coinsurance
- Your share after deductible. 20% means the plan pays 80%, you pay 20%.
- Out-of-Pocket Maximum
- Annual OOP max. After this, insurance pays 100%. HHS sets the ACA ceiling each year — $10,600 self-only / $21,200 family for 2026 plan years; your plan's actual limit may be lower and changes annually, so confirm it on your plan documents.
- Planned Procedure Costs
- Total cost of planned surgeries, procedures, or hospitalizations.
- Annual Prescription Costs
- Total annual cost of prescriptions before insurance.
- Regular Visit Costs
- Annual cost of regular doctor visits, specialists, and tests.
- Monthly Premium
- Your monthly health insurance premium.

Frequently Asked Questions
Why does Expected Out-of-Pocket stop increasing once Planned Procedure Costs gets high enough?
That's the out-of-pocket maximum doing exactly what it's designed to do: once your total cost-sharing (deductible plus coinsurance payments) reaches the plan's out-of-pocket maximum, the insurer covers 100% of any further covered costs for the rest of the plan year. The calculator caps Expected Out-of-Pocket at the Out-of-Pocket Maximum value you enter, so additional procedure costs beyond that point add nothing further to what you owe.
Does a higher Monthly Premium mean I'll pay less out of pocket?
Not according to this calculator's math -- Expected Out-of-Pocket is calculated purely from your deductible, coinsurance rate, and out-of-pocket maximum, with no reference to Monthly Premium at all. In reality, richer plans often do pair a higher premium with a lower deductible and out-of-pocket maximum, but that relationship isn't automatic, so compare the actual deductible and OOP max figures across plans rather than assuming premium alone tells the story.
What's the actual 2026 ACA out-of-pocket maximum, and does every plan use it?
Per HealthCare.gov, the ceiling is $10,600 for self-only coverage and $21,200 for family coverage for the 2026 plan year, but that's a maximum ceiling, not a mandated figure -- individual plans are free to set a lower out-of-pocket maximum than the federal cap, and many employer plans do. Always confirm the actual number on your plan's summary of benefits rather than assuming the federal limit applies.
Why do I pay the full cost below my deductible instead of my coinsurance rate?
The deductible is the amount you pay before your coinsurance benefit activates at all -- it represents costs the plan doesn't share in yet. Once your total covered medical spending crosses the deductible, the insurer starts covering its coinsurance share (commonly 70-80%) of every additional dollar, which is why Expected Out-of-Pocket rises dollar-for-dollar with costs below the deductible but more slowly above it.
