Every month, whether you visit a doctor or not, you owe your health insurance company a payment just to keep your coverage active. That payment is your premium — and for many Americans, it’s one of the largest recurring household expenses after rent or mortgage. So what is a premium in health insurance, and what are you actually paying for? In 2024, the average annual premium for employer-sponsored health insurance was $8,951 for single coverage and $25,572 for family coverage, according to the Kaiser Family Foundation. Employers typically cover about 83% of single premiums and 73% of family premiums — but the employee’s share still averages over $1,300 to $7,000 per year.
This article is part of our healthcare policy guide, where we translate insurance jargon into practical knowledge.
How Health Insurance Premiums Work
Your premium is the cost of having health insurance coverage — not the cost of using healthcare. Think of it like a membership fee. You pay the premium to maintain access to your plan’s network of doctors, hospitals, and pharmacies, as well as the negotiated rates and cost-sharing benefits the plan provides.
Premiums are typically paid monthly, though some employer plans deduct them from your paycheck on a biweekly or semi-monthly basis. If you buy insurance through the ACA marketplace (Healthcare.gov or a state exchange), you’ll pay monthly. Missing premium payments can result in a grace period (usually 30-90 days depending on the plan type) before your coverage is terminated.
Crucially, your premium is a separate cost from your deductible, copays, and coinsurance. Even after paying $500 or more per month in premiums, you still owe those additional amounts when you actually receive medical care.
What Determines Your Premium Amount?
Several factors influence how much you pay. Under the ACA, insurers can only use specific criteria to set premiums for individual and small group plans:
Age
Older adults pay more. The ACA allows insurers to charge their oldest adult enrollees up to 3 times more than their youngest adult enrollees (the “3:1 age rating ratio”). A 64-year-old may pay 3x the premium of a 21-year-old for the same plan. This reflects the reality that older adults use more healthcare on average.
Location
Premiums vary dramatically by geography. A plan in rural Wyoming may cost twice as much as a similar plan in urban Minnesota because of differences in local healthcare costs, hospital competition, and insurer participation. The cost of living and the number of insurers competing in your area both play a role.
Tobacco Use
The ACA permits insurers to charge tobacco users up to 50% more than non-users (though some states prohibit or limit this surcharge). Quitting smoking can reduce your premium significantly.
Plan Category (Metal Tier)
ACA marketplace plans are organized into metal tiers that reflect the plan’s actuarial value — the percentage of average healthcare costs the plan covers:
- Bronze: Covers ~60% of costs. Lowest premiums, highest out-of-pocket costs.
- Silver: Covers ~70% of costs. Moderate premiums and cost-sharing.
- Gold: Covers ~80% of costs. Higher premiums, lower cost-sharing.
- Platinum: Covers ~90% of costs. Highest premiums, lowest out-of-pocket costs.
Family Size
Adding a spouse or dependents increases your premium. Under the ACA, children are rated at a set amount per child up to three children (the fourth and beyond are free). Employer plans vary in how they structure employee-only versus employee-plus-family premium tiers.
Notably, the ACA prohibits insurers from varying premiums based on gender, health status, or pre-existing conditions for individual and small group market plans. This was one of the most significant consumer protections of the law.
Premiums vs. Total Healthcare Costs
A common mistake is choosing a plan based solely on the premium. The lowest-premium plan isn’t always the cheapest option overall — it depends on how much care you actually use.
Consider two hypothetical plans:
- Plan A: $250/month premium, $3,000 deductible, 30% coinsurance
- Plan B: $450/month premium, $500 deductible, 10% coinsurance
Annual premiums: Plan A = $3,000. Plan B = $5,400. Plan A is $2,400 cheaper in premiums alone.
But if you have a $15,000 surgery:
- Plan A total cost: $3,000 (premiums) + $3,000 (deductible) + $3,600 (30% of remaining $12,000) = $9,600
- Plan B total cost: $5,400 (premiums) + $500 (deductible) + $1,450 (10% of remaining $14,500) = $7,350
In a year with significant medical expenses, the higher-premium plan saves over $2,000. The lower-premium plan only wins if you use very little healthcare.

How to Reduce Your Health Insurance Premium
Several strategies can lower what you pay:
Premium Tax Credits (ACA Marketplace)
If you purchase insurance through Healthcare.gov or a state exchange, you may qualify for premium tax credits based on your household income. These subsidies have been significantly expanded — as of 2024, no household pays more than 8.5% of income toward the benchmark Silver plan premium. The Healthcare.gov application automatically calculates your eligibility.
Employer Contributions
If your employer offers health insurance, they likely cover a substantial portion of the premium. Employer-sponsored insurance is almost always cheaper than buying individual coverage because of group purchasing power and the employer subsidy. Additionally, your share of the premium is typically deducted pre-tax, reducing your taxable income.
Choose a Higher-Deductible Plan
Opting for a high-deductible health plan (HDHP) lowers your premium. If you’re relatively healthy and don’t anticipate major medical expenses, the premium savings can outweigh the risk of a higher deductible. Pairing an HDHP with a Health Savings Account (HSA) provides additional tax benefits: contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free.
Quit Tobacco
If you’re a tobacco user paying a surcharge, quitting can reduce your premium by up to 50% of the surcharge amount. Many insurers and employers offer free smoking cessation programs.
Premiums and the ACA Marketplace: What You Need to Know
If you purchase insurance through Healthcare.gov or a state exchange, premium affordability looks very different than sticker prices suggest. Premium tax credits — also called subsidies — reduce your monthly payment based on household income and the cost of plans in your area.
Under current rules (extended through at least 2025), households earning up to 400% of the federal poverty level qualify for premium assistance, and even those above 400% FPL are protected from spending more than 8.5% of income on the benchmark Silver plan. In practice, this means a single adult earning $35,000 might pay $175/month for a Silver plan that has a sticker price of $500+. Families with moderate incomes often qualify for significant reductions.
Some lower-income enrollees also qualify for cost-sharing reductions (CSRs), which lower deductibles, copays, and coinsurance on Silver plans. These are separate from premium tax credits and only available at the Silver tier. Together, premium credits and CSRs can make comprehensive coverage surprisingly affordable for many households — but you must enroll through the marketplace to access them. Plans purchased directly from an insurer outside the marketplace don’t qualify for subsidies.
What Happens If You Don’t Pay Your Premium?
Skipping premium payments puts your coverage at risk. The grace period depends on your plan type:
- ACA marketplace plans (with premium tax credits): 90-day grace period. During the first 30 days, claims are still paid. During days 31-90, claims may be held or denied. After 90 days, your plan is terminated retroactively to the end of the first month.
- Employer-sponsored plans: Grace periods vary. Most employers offer a 30-day grace period before terminating coverage.
- Other individual plans: Typically a 30-day grace period, though terms vary by state and insurer.
Losing coverage due to non-payment of premiums may qualify you for a Special Enrollment Period to purchase new coverage — but there will be a gap during which you’re uninsured.
Frequently Asked Questions
Is the premium the same as the deductible?
No. The premium is your monthly payment to maintain coverage. The deductible is the amount you pay out of pocket for covered services before your insurance starts sharing costs. You pay the premium whether you use healthcare or not; the deductible only matters when you do.
Do premiums count toward the out-of-pocket maximum?
No. Premiums are not included in your out-of-pocket maximum. Only deductible payments, copays, and coinsurance count toward that limit. This is an important distinction when calculating your total potential healthcare spending for the year.
Why did my premium increase this year?
Premiums increase for several reasons: rising healthcare costs (provider rates, drug prices), changes in the risk pool, regulatory changes, aging (you move to a higher age band), and inflation in medical services. Insurers must justify rate increases to state regulators, but annual premium growth of 3-8% is common.
Can I deduct health insurance premiums on my taxes?
If you’re self-employed, you can typically deduct 100% of your health insurance premiums. For employees, premiums paid through an employer plan are usually pre-tax (deducted before income tax). If you pay premiums with after-tax dollars, you may deduct them if your total medical expenses exceed 7.5% of your adjusted gross income.
The Bottom Line
Your health insurance premium is the price of admission — the monthly fee that keeps your coverage active and gives you access to negotiated provider rates, cost-sharing benefits, and catastrophic protection. But the premium alone doesn’t tell you what healthcare will cost. To make a smart plan choice, you need to weigh the premium against the deductible, coinsurance, copays, and out-of-pocket maximum — and estimate how much care you’re likely to use in the coming year. The cheapest premium isn’t always the best deal, and the most expensive plan isn’t always worth the extra cost. Run the numbers for your specific situation.
