The Five Terms That Control Your Health Care Costs
Every health insurance plan comes with its own price tag — and that price tag isn't just the monthly bill. There are five core cost terms that together determine what you actually spend on health care in any given year. Understanding how they interact is the fastest way to compare plans intelligently and avoid bill surprises.
| Typical individual deductible range | $500 – $8,000+ per year (Varies widely by plan type and metal tier) |
| ACA out-of-pocket maximum (individual, 2024) | $9,450 (U.S. Department of Health & Human Services, 2024) |
| Premium payment frequency | Monthly (most common) |
| Coinsurance split (common example) | 80/20 (insurer/member) (Plan terms vary; check your Summary of Benefits) |
| Cost terms that count toward out-of-pocket max | Deductible + copays + coinsurance (Premiums do not count toward the out-of-pocket maximum) |

Premiums: Your Fixed Monthly Cost
The premium is what you pay every month to keep your plan active — whether or not you see a doctor that month. If you get insurance through an employer, your employer typically pays a portion and deducts the rest from your paycheck. If you buy a plan through the marketplace, you pay the full premium (minus any subsidy you qualify for).
Premiums are predictable, but they're only part of the picture. A low-premium plan almost always comes with higher cost-sharing when you actually need care — meaning a higher deductible, steeper coinsurance, or both.
Premiums Don't Count Toward Your Deductible
Deductibles, Copays, and Coinsurance: What You Pay When You Use Care
These three terms control your spending when you actually access health services. They work in a specific sequence:
- Deductible first. You pay the full allowed cost of most covered services until you've met your annual deductible. Some plans exempt certain services — like preventive care or a fixed copay for primary care visits — from the deductible.
- Copays and coinsurance after. Once you've cleared your deductible, you typically pay either a flat copay (e.g., $40 per specialist visit) or a coinsurance percentage (e.g., 20% of the allowed amount) for each service.
Premium
The fixed monthly amount you pay to keep your health insurance active, regardless of whether you use any care that month. Missing premium payments can cause your policy to lapse.
Deductible
The amount you pay out of pocket for covered services before your insurer starts sharing the cost. For example, with a $1,500 deductible, you pay the first $1,500 in covered expenses each plan year.
Copay
A fixed dollar amount you pay for a specific service at the time of the visit—such as $30 for a primary care appointment. Copays often apply even before your deductible is met, depending on your plan.
Coinsurance
Your share of a covered medical bill expressed as a percentage, paid after you've met your deductible. If your coinsurance is 20%, you pay 20% of the allowed amount and your insurer covers the remaining 80%.
Out-of-Pocket Maximum
The most you'll pay for covered services in a single plan year. Once you hit this limit, your insurer pays 100% of covered in-network costs for the rest of the year.
Allowed Amount
The maximum price your insurer has agreed to pay for a specific service from an in-network provider. You are responsible for any cost-sharing on top of this negotiated rate.

The Out-of-Pocket Maximum: Your Annual Safety Net
The out-of-pocket maximum is the most important number most people ignore when picking a plan. It caps your total exposure for covered in-network services in a plan year. Once you hit that ceiling — through any combination of deductible spending, copays, and coinsurance — your insurer covers 100% of covered in-network costs for the rest of the year.

ACA individual out-of-pocket maximum (2024)
Set annually by the U.S. Department of Health & Human Services; costs beyond this limit are covered 100% by the insurer for in-network care.
~83%
Workers enrolled in plans with a general deductible
According to the KFF Employer Health Benefits Survey, the vast majority of employer-sponsored plan enrollees face a deductible before full coverage kicks in.
Keep in mind: premiums, out-of-network charges, and costs for non-covered services do not count toward your out-of-pocket maximum. Always confirm what your specific plan includes by reading your Summary of Benefits and Coverage document, or by contacting a licensed insurance agent.
