Why These Terms Matter
When evaluating health insurance plans, most people focus on the monthly premium — the amount you pay each month to maintain coverage. But the premium is only one piece of the cost puzzle. Understanding deductibles, copays, coinsurance, and out-of-pocket maximums is essential to accurately comparing plans and predicting your actual healthcare costs.
The Premium
The premium is the fixed monthly amount you pay for health insurance coverage, regardless of whether you use any healthcare services. For employer-sponsored plans, the employer typically pays a portion of the premium and the employee pays the remainder through payroll deductions.
A lower premium doesn't always mean a cheaper plan — plans with lower premiums often have higher deductibles and out-of-pocket costs, which can make them more expensive if you use healthcare services frequently.
The Deductible
The deductible is the amount you must pay out-of-pocket for covered healthcare services before your insurance begins to share costs. For example, if your plan has a $1,500 deductible, you pay the first $1,500 of covered medical expenses each year. After that, your insurance starts contributing.
- Individual vs. family deductibles: Family plans have both an individual deductible (per person) and a family deductible (aggregate).
- Preventive care: Most plans cover preventive services without requiring you to meet your deductible first.
- Network matters: Deductibles typically apply only to in-network care.
Copays
A copay (or copayment) is a fixed dollar amount you pay for a specific healthcare service, regardless of the total cost. Common examples include a $25 copay for a primary care visit or a $50 copay for a specialist visit. Copays are straightforward and predictable — you know exactly what you'll pay before you walk into the office.
Coinsurance
Coinsurance is the percentage of costs you share with your insurance company after you've met your deductible. For example, with 80/20 coinsurance, your insurer pays 80% and you pay 20% of covered costs after the deductible. Coinsurance applies to services that don't have a fixed copay, such as surgeries, hospital stays, or specialist procedures.
The Out-of-Pocket Maximum
The out-of-pocket maximum is the most you will ever pay for covered healthcare services in a plan year. Once you reach this limit — through your deductible, copays, and coinsurance combined — your insurance covers 100% of covered costs for the rest of the year. In 2025, the ACA limits out-of-pocket maximums to $9,200 for individuals and $18,400 for families in employer-sponsored plans.
How These Costs Work Together: An Example
| Scenario | Plan A (Low Premium, High Deductible) | Plan B (High Premium, Low Deductible) |
|---|---|---|
| Monthly Premium | $350 | $550 |
| Annual Deductible | $3,000 | $500 |
| Coinsurance | 20% | 20% |
| Out-of-Pocket Max | $7,000 | $4,000 |
| Annual Premium Cost | $4,200 | $6,600 |
| Best For | Healthy, low-utilization employees | Employees with ongoing medical needs |
Choosing the Right Balance for Your Team
The right plan depends on your employees' healthcare utilization patterns. A workforce of young, healthy employees may benefit from lower-premium, higher-deductible plans — especially when paired with employer HSA contributions. A workforce with older employees or those managing chronic conditions may be better served by plans with lower deductibles and more predictable cost-sharing.
