2026 Obamacare Premiums by State: How Much Will You Pay?
Health insurance premiums on the ACA marketplace are not the same everywhere. Depending on where you live, the cost of a benchmark Silver plan can vary by thousands of dollars per year. Your age, household size, and income all play a role too, but your state and county are among the biggest factors driving what you actually pay.
Here is an overview of how ACA premiums break down across the country in 2026, which states are cheapest and most expensive, and what factors are behind the differences.
How ACA Premiums Are Determined
Before diving into state-level numbers, it helps to understand what goes into your premium. ACA marketplace premiums are based on five main factors:
- Age: Older enrollees pay more. Under ACA rules, insurers can charge a 64-year-old up to 3 times what they charge a 21-year-old for the same plan. This is the single biggest factor in your premium.
- Location: Premiums are set at the county level, not just the state level. Rural areas with fewer hospitals and insurers typically have higher premiums than competitive urban markets.
- Plan tier: The ACA uses four metal tiers -- Bronze, Silver, Gold, and Platinum. Bronze plans have the lowest premiums but highest out-of-pocket costs. Platinum plans are the reverse. Silver is the benchmark used for subsidy calculations.
- Tobacco use: Insurers in most states can charge tobacco users up to 50% more. A few states (California, New York, New Jersey, and others) prohibit this surcharge.
- Number of enrollees: Your premium is per person. A family of four pays for four individual premiums (though children under 21 are capped at three).
Notably, the ACA prohibits insurers from charging more based on health status, pre-existing conditions, or gender. These protections remain in effect for 2026.
The Benchmark Silver Plan: Why It Matters
The "benchmark" plan is the second-lowest-cost Silver plan available in your area. This is the plan the federal government uses to calculate your premium tax credit (subsidy). Even if you choose a different plan, your subsidy amount is always based on the benchmark Silver plan.
Key point: If the benchmark Silver plan in your area is expensive, your subsidy will be larger (assuming you qualify). If the benchmark is cheap, your subsidy will be smaller. This is why the same income can lead to very different out-of-pocket costs in different states.
Cheapest States for ACA Premiums
States with competitive insurance markets, large populations, and multiple insurers tend to have the lowest premiums. The following states consistently rank among the most affordable for a benchmark Silver plan (shown for a 40-year-old, before subsidies):
| State | Benchmark Silver (40-yr-old) | Key Factor |
|---|---|---|
| New Hampshire | $401/mo | Strong insurer competition |
| Maryland | $414/mo | State reinsurance program |
| Minnesota | $448/mo | State reinsurance program |
| Virginia | $455/mo | State reinsurance program |
| Indiana | $474/mo | Multiple competing insurers |
Several of these states benefit from state-based reinsurance programs, which use state funds to cover the highest-cost enrollees and bring down premiums for everyone else. Minnesota and Maryland have been particularly successful with this approach.
Most Expensive States for ACA Premiums
States with limited insurer competition, high health care costs, or large rural populations tend to have the highest premiums:
| State | Benchmark Silver (40-yr-old) | Key Factor |
|---|---|---|
| Vermont | $1,299/mo | Small market, community rating |
| Wyoming | $1,090/mo | Few insurers, rural state |
| West Virginia | $1,073/mo | Older, sicker population |
| Alaska | $1,032/mo | High health care costs |
| Connecticut | $870/mo | High health care costs |
Vermont has the highest benchmark premium in 2026. The state uses community rating, so a 40-year-old pays the same price as a 60-year-old, which pushes the age-40 figure well above states that charge older enrollees more. In Wyoming, few insurers and a small, spread-out population leave little competitive pressure to keep premiums down. West Virginia faces a similar challenge compounded by an older average population with higher health care utilization.
Why Premiums Vary So Much Within a State
Even within the same state, premiums can differ dramatically from one county to the next. A benchmark Silver plan in downtown Denver might cost $400 per month, while the same plan in a rural Colorado mountain county could cost $700 per month. This happens because:
- Provider networks: Areas with more hospitals and doctors have more negotiating leverage, which can lead to lower costs.
- Insurer competition: Urban counties often have 5 or more insurers competing for enrollees. Rural counties may have only one or two.
- Local health care costs: Hospital pricing varies enormously. A hip replacement might cost $20,000 in one city and $50,000 in another, and those differences show up in premiums.
- Risk pool composition: Rating areas with a disproportionate number of older or sicker enrollees will see higher premiums for everyone.
How Age Affects Your Premium
Age is the other major driver of your premium. Here is how the same benchmark Silver plan might look at different ages in a mid-cost state:
| Age | Approximate Monthly Premium | Annual Cost |
|---|---|---|
| 21 | ~$489 | ~$5,870 |
| 30 | ~$555 | ~$6,660 |
| 40 | ~$625 | ~$7,500 |
| 50 | ~$873 | ~$10,480 |
| 60 | ~$1,327 | ~$15,920 |
| 64 | ~$1,467 | ~$17,600 |
These are full-price premiums before any subsidy is applied. If you qualify for a premium tax credit, your actual cost could be much lower. The subsidy is designed to bring your cost down to a percentage of your income, but the exact amount depends on the benchmark plan in your specific area.
State-Based Marketplaces vs. HealthCare.gov
Most states use the federal marketplace (HealthCare.gov) to sell ACA plans. However, 18 states and Washington, D.C. operate their own state-based marketplaces. States that run their own exchanges sometimes have additional subsidies, unique plan options, or extended enrollment periods:
- California (Covered California) has offered state-funded subsidies for people between 400% and 600% FPL.
- Massachusetts (Health Connector) has some of the most generous state-level subsidy structures.
- Colorado, New York, and Washington have implemented public option or standardized plan designs to increase competition and transparency.
If you live in a state with its own marketplace, check your state exchange directly, as you may find benefits not available through the federal site.
How to Find Your Actual Cost
The numbers in this article are averages and estimates. Your actual premium depends on your specific county, age, household size, and income. The most accurate way to find out what you will pay is to run the numbers with a subsidy calculator.

Check Your Subsidy →The Bottom Line
ACA marketplace premiums in 2026 range from roughly $400 to $1,300 per month for a benchmark Silver plan for a 40-year-old, depending on the state. But what you actually pay depends on your subsidy, which is tied to your income and the cost of plans in your specific county. States with strong insurer competition and reinsurance programs tend to be the most affordable, while rural states with limited options remain the most expensive.
No matter where you live, the most important step is checking your subsidy eligibility. A premium that looks unaffordable at full price may be very manageable after your tax credit is applied.
