Deductible vs. Out-of-Pocket Maximum: What You'll Actually Pay

Learn how your deductible, copays, coinsurance, and out-of-pocket maximum add up, with a worked example and the 2027 federal cap.

A deductible and an out-of-pocket maximum are the two numbers that decide most of your yearly health care costs. The deductible is what you pay before your plan starts sharing costs. The out-of-pocket maximum is the most you pay in a year for covered in-network care. Copays and coinsurance fill the space between them. This guide explains each term and walks through a worked example.

What is a deductible?

A deductible is the amount you pay for covered care before your plan starts to pay its share. A plan with a $3,000 deductible leaves you paying the first $3,000 of covered bills each year. Preventive care is the main exception. ACA plans cover preventive services like checkups and screenings at no cost, even before you meet the deductible. Many plans also cover some visits or generic drugs with a copay before the deductible.

What is an out-of-pocket maximum?

An out-of-pocket maximum is the most you pay for covered, in-network care in one plan year. After you reach it, the plan pays 100% of covered in-network costs for the rest of the year. Your deductible, copays, and coinsurance all count toward it. Your premium does not count. For 2027, federal rules cap the out-of-pocket maximum for ACA-compliant plans at $12,000 for one person and $24,000 for a family.

How do copays and coinsurance fit in?

Copays and coinsurance are your share of each bill, usually after the deductible. The five cost terms work together:

  • Premium: the monthly price to keep the plan; never counts toward the out-of-pocket maximum
  • Deductible: what you pay first for covered care each year
  • Copay: a flat fee per visit or prescription, such as $40
  • Coinsurance: a percentage of the bill, such as 20%, after the deductible
  • Out-of-pocket maximum: the yearly ceiling on deductible, copays, and coinsurance

How do the deductible and out-of-pocket maximum work in a real year?

A worked example shows how the deductible and out-of-pocket maximum stack up. The example uses a sample plan, not a real quote.

Sample plan featureAmount
Deductible$4,000
Coinsurance after the deductible20%
Out-of-pocket maximum$8,000
Covered in-network surgery bill$30,000

The patient pays the first $4,000 as the deductible. Coinsurance applies to the next $26,000, which would be $5,200 at 20%. The out-of-pocket maximum caps the patient's total at $8,000. The plan pays the remaining $22,000. Any further covered in-network care that year costs the patient nothing.

Which number matters more when you choose a plan?

The out-of-pocket maximum matters more if you worry about a big medical event. The deductible matters more for everyday budgeting. Use these rules:

  • Healthy and saving: a higher deductible with a lower premium may fit
  • Regular care: a lower deductible keeps routine costs predictable
  • Planned surgery or pregnancy: compare plans by out-of-pocket maximum
  • Worst-case budget: add 12 months of premium plus the out-of-pocket maximum

The worst-case total shows the most you could spend in a year on covered in-network care. Compare that total across plans before you choose.

What doesn't count toward the out-of-pocket maximum?

Several costs never count toward the out-of-pocket maximum. Watch for these:

  • Monthly premiums: never count
  • Out-of-network care: usually doesn't count, unless the plan says otherwise
  • Non-covered services: don't count
  • Balance bills: out-of-network bills outside federal surprise-billing protections don't count

Federal surprise-billing rules protect you from most out-of-network bills for emergency care and at in-network hospitals. Stay in network whenever you can.
