Health insurance comes with several costs, and the terms can sound frustratingly similar. What is the difference between a copay and a deductible? When does coinsurance begin? Does your monthly premium count toward your out-of-pocket maximum?
Understanding these terms can help you compare health plans more accurately and avoid surprises when you receive medical care. Here is a simple explanation of the five costs you are most likely to see.
Health Insurance Costs at a Glance
| Term | What it means |
|---|---|
| Premium | The amount you pay to keep your health coverage active |
| Deductible | The amount you pay for certain covered services before the plan begins sharing those costs |
| Copay | A fixed amount you pay for a covered service |
| Coinsurance | A percentage of the allowed cost you pay, often after meeting the deductible |
| Out-of-pocket maximum | The most you pay in a plan year for covered, in-network services that count toward the limit |
These figures are only examples. Every plan has its own benefits, network rules, exclusions, and cost-sharing amounts.
What Is a Health Insurance Premium?
Your premium is the amount you pay regularly—usually every month—to keep your health insurance active. You pay it whether or not you visit a doctor or use medical services that month.
Think of the premium as the cost of having the coverage available. It is separate from what you may pay when you actually receive care.
Important: Premium payments generally do not count toward your deductible or out-of-pocket maximum.
What Is a Deductible?
Your deductible is the amount you pay for certain covered health care services before your insurance plan begins sharing the cost.
For example, suppose your plan has a $2,000 deductible. For services that are subject to that deductible, you generally pay the plan’s negotiated or allowed amount until your payments reach $2,000. After that, the plan may begin paying a portion while you pay a copay or coinsurance.
Not every service necessarily requires you to meet the deductible first. Many plans cover certain services—such as eligible preventive care—before the deductible, and some plans offer doctor visits or prescriptions for a copay before the deductible is met.
What Is a Copay?
A copay, short for copayment, is a fixed dollar amount you pay for a covered service.
For example, your plan might charge:
- $30 for a primary care visit
- $60 for a specialist visit
- $15 for a generic prescription
- $100 for an urgent care visit
Because a copay is fixed, you usually know the amount ahead of time. However, the visit may include additional services—such as lab work or imaging—that have separate costs.
Whether copays apply before or after the deductible, and whether they count toward the deductible, depends on the plan. Review the plan’s Summary of Benefits and Coverage for the exact rules.
What Is Coinsurance?
Coinsurance is a percentage of the allowed cost of a covered service that you pay. It often applies after you meet your deductible.
Suppose your plan has 20% coinsurance and the allowed amount for a covered procedure is $1,000:
- You pay 20%, or $200.
- Your insurance plan pays 80%, or $800.
Your coinsurance is calculated from the plan’s allowed amount, not necessarily the amount originally billed by the provider. Staying in your plan’s network is important because out-of-network care can follow different rules and may cost much more.
What Is an Out-of-Pocket Maximum?
Your out-of-pocket maximum is the most you pay during a plan year for covered services that count toward the limit. Deductibles, copays, and coinsurance for eligible care generally count toward it.
Once you reach that maximum, your plan generally pays 100% of the allowed cost for covered, in-network services for the remainder of the plan year.
The out-of-pocket maximum generally does not include:
- Your monthly premiums
- Services your plan does not cover
- Costs above the plan’s allowed amount
- Certain out-of-network expenses
How These Costs Work Together: A Simple Example
Imagine a health plan with the following costs:
- $350 monthly premium
- $2,000 annual deductible
- 20% coinsurance after the deductible
- $8,000 out-of-pocket maximum
You pay the monthly premium to keep the coverage active. If you then need a covered procedure subject to the deductible, you pay the allowed costs until you have met the $2,000 deductible.
After meeting the deductible, the plan begins sharing eligible costs. With 20% coinsurance, you pay 20% and the plan pays 80%. You continue paying your share until your eligible payments reach the $8,000 out-of-pocket maximum. At that point, the plan generally pays 100% for additional covered, in-network care for the rest of the plan year.
If your plan offers copays for certain visits or prescriptions, those may apply at different stages. The Summary of Benefits and Coverage explains how each service is handled.
Copay vs. Deductible: What Is the Difference?
A deductible is an amount you accumulate toward during the plan year before the plan begins sharing the cost of certain services. A copay is a fixed fee for a particular covered service.
You might have both. For example, a plan may offer a $30 primary care copay while applying the deductible to hospital care, imaging, or other services.
Copay vs. Coinsurance: What Is the Difference?
A copay is a fixed dollar amount. Coinsurance is a percentage of the allowed cost.
If your specialist copay is $60, you generally pay $60 for the covered visit. If a service instead has 20% coinsurance, your exact cost depends on the allowed amount for that service.
How to Compare Health Plans More Accurately
Do not compare plans based only on the monthly premium. A lower-premium plan may have a higher deductible, higher coinsurance, or a larger out-of-pocket maximum.
Before enrolling, review:
- The monthly premium after any available savings
- The medical and prescription deductibles
- Copays for primary care, specialists, urgent care, and prescriptions
- Coinsurance for hospital care, procedures, labs, and imaging
- The individual and family out-of-pocket maximums
- Whether your doctors, hospitals, and medications are in the plan’s network and formulary
You can find much of this information in the plan’s Summary of Benefits and Coverage. HealthCare.gov also provides an official guide to estimating your total health care costs.
