ACA Premiums at Age 59 in 2026: All 50 States and D.C.

A 59-year-old pays 2.04 times the standard ACA benchmark premium in 2026, up to $2,269 per month in Wyoming, the most expensive state. Every year, the Centers for Medicare & Medicaid Services publishes ACA premium data anchored to a 40-year-old. That benchmark drives how subsidies are calculated, how journalists cover open enrollment and how states compare their markets. It's the right lens for most of what happens in the marketplace.

But for the 5.5 million Americans aged 55 to 64 enrolled in ACA plans (the single largest ten-year age band in the marketplace), the 40-year-old figure tells them almost nothing about what they'll pay. Under the ACA's age-rating rules, a 59-year-old pays 2.04 times as much in most states. That's not a rough estimate. It's derived from the standard CMS age curve, built into federal rate-filing requirements and confirmed against direct age-band data in CMS Rate Public Use Files. Two states (Massachusetts and New Jersey) use state-specific age curves with a narrower ratio; their figures in this analysis reflect those curves.

In Wyoming, the most expensive state in this analysis, the age-40 Silver benchmark is $1,114 per month. For a 59-year-old, the same plan costs $2,269 per month ($27,228 per year). That gap is not Wyoming-specific. It compounds whatever the base rate happens to be in any state.

This analysis extends MoneyGeek's 2026 ACA premium dataset to calculate what a 59-year-old pays in all 50 states and Washington, D.C. For 48 age-rated states, the federal default curve produces a ratio of 2.037 (rounded to 2.04) between the age-40 and age-59 rate factors. Massachusetts and New Jersey use state-specific curves with a narrower 1.637 ratio. Three jurisdictions (New York, Vermont and Washington, D.C.) use community rating, where age doesn't affect premiums at all.

The 2026 open enrollment period arrived alongside a new financial reality. The enhanced premium tax credits first enacted by the American Rescue Plan Act of 2021 and extended through 2025 expired on December 31, 2025. Congress did not renew them. For a 59-year-old earning above 400% of the federal poverty level (roughly $62,400 for a single individual in 2026), the subsidy support that once softened these costs is gone. The state-by-state dollar impact of that expiration on unsubsidized enrollees is covered in our ACA Subsidy Cliff 2026 analysis. This study focuses on the underlying premium structure: what age-rated coverage costs before any subsidy enters the picture.

When CMS publishes its annual benchmark premium data, it uses a 40-year-old as the standard reference point. Every headline about "2026 ACA premiums", including MoneyGeek's own 50-state analysis, describes what a 40-year-old would pay.

A 59-year-old pays roughly 2.04 times as much in most states.

Under the ACA's age-rating rules, insurers may charge older enrollees up to 3 times the rate of a 21-year-old. The standard CMS age curve assigns a factor of 2.603 to age 59 and 1.278 to age 40, producing a ratio of 2.037 (rounded to 2.04 for rate-filing purposes). That ratio applies in 48 age-rated states. Massachusetts and New Jersey operate under state-specific curves that produce a narrower 1.637 ratio at age 59, reflecting those states' 2:1 maximum age-rating limits.

Wyoming is the most expensive state in this analysis. Its age-40 Silver benchmark is $1,114 per month. Apply the 2.04x curve and the same plan costs a 59-year-old $2,269 per month, or $27,228 per year. That figure assumes no premium tax credit, which phases out entirely as income climbs above 400% of the federal poverty level ($62,400 for a single individual in 2026). As of January 1, 2026, the enhanced subsidies that had extended help to higher-income enrollees have expired.

No major coverage outlet or government summary publishes what a 59-year-old pays in every state. CMS includes age-band rate data in its Rate Public Use Files, but the conversion to age-specific dollar figures doesn't appear in standard ACA coverage. This analysis does that calculation for 2026, for all 51 jurisdictions.

The audience is real and large. These are self-employed workers, early retirees bridging the gap before Medicare eligibility at 65, workers displaced from employer coverage in their late 50s and spouses whose own Medicare eligibility hasn't vested yet. For all of them, the 40-year-old headline rate is the wrong number.

Three states post age-59 Silver-tier premiums above $2,100 per month, a level that annualizes above $25,000.

Wyoming holds the #1 position at $2,269 per month ($27,228 per year). The state's small individual market, sparse insurer competition and high underlying medical costs push an age-40 rate to $1,114, already well above the national median, which the 2.04x multiplier then compounds. Wyoming has not expanded Medicaid, meaning a 59-year-old above the income floor for marketplace subsidies has no alternative public option.

West Virginia ranks second at $2,218 per month ($26,616 per year). Unlike Wyoming, West Virginia did expand Medicaid, but that protection applies only to those at or below 138% of the federal poverty level. Above that threshold, marketplace coverage is the only option, and the age-40 base of $1,089 per month produces one of the steepest bills in the country.

Alaska is third at $2,118 per month ($25,416 per year). Alaska's premiums reflect geographic isolation, high labor costs for providers and the structural challenges of insuring a dispersed, rural population. Its reinsurance program has moderated premiums somewhat. Alaska is the only state where age-40 premiums actually fell in 2026, but age-59 costs still exceed $25,000 per year.

Nine states cross the $20,000 per year threshold for age-59 Silver-tier coverage. Beyond Wyoming, West Virginia and Alaska:

• Nebraska: $1,870 per month ($22,440 per year)
• New Mexico: $1,868 per month ($22,416 per year)
• Georgia: $1,754 per month ($21,048 per year)
• Connecticut: $1,750 per month ($21,000 per year)
• Florida: $1,750 per month ($21,000 per year)
• Arkansas: $1,676 per month ($20,112 per year)

Connecticut is a high-income, high-cost state that has expanded Medicaid and built extensive consumer protections, but its underlying insurance market still produces a top-tier age-59 figure. Florida's ranking (#8 at $1,750 per month) is compounded by its status as a non-expansion state and its marketplace scale: Florida alone has 917,243 enrollees aged 55 to 64, the largest such cohort of any state.

Twenty-eight more states fall between $15,000 and $20,000 annually, including large-enrollment states like Texas ($1,603 per month), North Carolina ($1,579 per month), Pennsylvania ($1,446 per month), California ($1,395 per month) and Michigan ($1,393 per month). The middle tier still means $1,261 to $1,603 per month for a single coverage purchase.

The median state in this analysis is Nevada, at $1,418 per month ($17,016 per year).

Three jurisdictions (New York, Vermont and Washington, D.C.) use community rating rules that prohibit age-based premium variation. A 59-year-old and a 40-year-old pay identical premiums for the same plan. New York's community-rated premium of $1,154 per month ($13,848 per year) ranks 44th in this analysis. Vermont's $1,223 per month ($14,676 per year) ranks 38th. Washington, D.C.'s $621 per month ($7,452 per year) ranks last.

Massachusetts and New Jersey use state-specific age curves with a 1.637 ratio between the age-40 and age-59 rate factors, narrower than the 2.04 applied in most states. For a 59-year-old, this produces substantially lower premiums than the federal curve would yield: Massachusetts ranks #41 at $1,175 per month ($14,100 per year) and New Jersey ranks #48 at $1,079 per month ($12,948 per year). Both states' rankings would be much higher if the federal 2.04x curve applied.

The 2.04x multiplier is a ratio, but its real weight is a dollar figure. In the most expensive states, the gap between what a 40-year-old pays and what a 59-year-old pays for the same plan exceeds $1,000 per month. Not because the 59-year-old gets different coverage, but purely because of age. That surcharge compounds across 12 months regardless of whether a single claim is filed.

The five states below have the largest absolute monthly dollar difference between the age-40 and age-59 benchmark Silver-tier premium. It's a different lens than the overall premium ranking: a state can have a mid-tier premium but still produce a large age gap if its base rate is high enough for the multiplier to amplify.

The smallest age gaps are in the community-rated jurisdictions: New York, Vermont and Washington, D.C. all post a $0 age gap. Among age-rated states, New Hampshire ($500 per month gap) and Maryland ($495 per month) have the smallest absolute differences. Massachusetts and New Jersey, with their narrower state curves, post gaps of $457 per month and $420 per month respectively.

Americans aged 55 to 64 are the single largest ten-year age band in the ACA marketplace. 5.5 million enrollees in this group held marketplace coverage as of the most recent enrollment period, accounting for 22.6% of total ACA marketplace enrollment.

The geographic concentration of this cohort tracks closely with the most expensive states:

• Florida: 917,243 enrollees aged 55 to 64
• Texas: 720,935
• California: 548,814
• Georgia: 285,480
• North Carolina: 224,592

Florida's 917,243-person 55 to 64 cohort, the largest of any state, is paying a market rate of $1,750 per month in 2026 unsubsidized. With enhanced premium tax credits now expired, enrollees above 400% of the federal poverty level (roughly $62,400 for a single individual) pay the full rate shown in this analysis.

The 55 to 64 marketplace cohort is distinct from the broader unsubsidized population (1.57 million enrollees nationally) covered in MoneyGeek's ACA Subsidy Cliff 2026 analysis. The 55 to 64 group is much larger, includes many subsidy recipients and represents the cohort most exposed to age-rated premiums in absolute dollar terms. It breaks into four main groups: self-employed workers carrying their own coverage, early retirees bridging the gap before Medicare eligibility at 65, workers displaced from employer coverage in their late 50s and spouses of Medicare-eligible enrollees whose own eligibility hasn't yet vested.

For most of this cohort, the marketplace isn't a permanent home. It's a bridge. A $1,500 to $2,000 per month bridge can drain retirement savings rapidly.

This is also the cohort with the fewest alternatives. Unlike enrollees under 138% of the federal poverty level in expansion states who can access Medicaid, most 55 to 64-year-olds on marketplace plans are solidly middle-income, above the Medicaid floor, below the income levels where premium exposure becomes trivial. For context on how many Americans are currently without coverage, this age group is disproportionately represented.

Nine states have not expanded Medicaid under the ACA: Alabama, Florida, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin (partial expansion to 100% FPL only) and Wyoming. For a 59-year-old in one of these states, the coverage gap is acute. Between the Medicaid income cutoff and Medicare eligibility at 65, there is a six-year window where marketplace coverage is the only insured option, at full age-rated price and now without the enhanced subsidy support that expired in January 2026.

Six of the nine non-expansion states rank in the top 20 of this analysis by age-59 premium:

• Wyoming: Rank #1, $2,269 per month
• Florida: Rank #8, $1,750 per month
• Texas: Rank #10, $1,603 per month
• Tennessee: Rank #14, $1,568 per month
• Kansas: Rank #16, $1,548 per month
• Mississippi: Rank #19, $1,513 per month

The overlap isn't a coincidence. States with thinner individual insurance markets and less insurer competition produce higher base premiums. The 2.04x multiplier amplifies whatever that base is. A 59-year-old in a non-expansion state doesn't just pay more than a 40-year-old in the same state. They also pay more than a 59-year-old in an expansion state with better market infrastructure. MoneyGeek's state health care quality rankings show the same states repeatedly at the bottom on access and affordability measures.

Consider a 59-year-old in Mississippi earning $70,000 per year, above the 400% FPL subsidy cliff of roughly $62,400. With enhanced tax credits gone, that person pays the full unsubsidized rate: $1,513 per month, or $18,156 per year. No state-based backfill exists in Mississippi. No reinsurance program suppresses the base rate. And no Medicaid alternative exists for those who earn less but fall above the non-expansion state's traditional Medicaid cutoff.

The non-expansion states that rank lower, Alabama (#25), South Carolina (#32) and Wisconsin (#21), still post premiums above $1,300 per month for a 59-year-old, with no full Medicaid alternative for the working-poor gap population.

The political dimension of this divide is documented in MoneyGeek's analysis of how uninsured rates vary by state along partisan lines. The 55 to 64 cohort in non-expansion states faces the sharpest version of that gap.

The ACA permits insurers to charge older enrollees up to 3 times the rate charged to a 21-year-old for the same plan. CMS translates this into a specific age-rating curve that assigns a factor to every age.

Under the standard CMS curve, age 59 carries a factor of 2.603 and age 40 carries a factor of 1.278. The ratio is 2.037, which rounds to 2.04 for rate-filing purposes. This is not a maximum that insurers choose to apply or not. It's the standard factor required by the federal default curve in states that haven't established their own.

The math: if an age-40 benchmark Silver-tier premium is $700 per month, the age-59 rate is $700 × 2.04 = $1,428 per month. The premium doesn't inch up between 40 and 59. It more than doubles across the 19-year span.

Three jurisdictions (New York, Vermont and Washington, D.C.) use community rating, which prohibits age variation entirely. Two states (Massachusetts and New Jersey) use a narrower 2:1 maximum age-rating ratio with state-established curves. Their age-59/age-40 ratio is 1.637 under the CMS State-Specific Age Curve Variations document. For these states, the gap between what a 40-year-old and 59-year-old pay is substantially smaller than in the other 48 states.

For all other 48 states, the 2.04x curve is the operative reality. Changing insurers, shopping plans or living in a different ZIP code can move the base rate, but the age multiplier stays fixed.

MoneyGeek extended its proprietary 2026 ACA Marketplace premium analysis to calculate Silver-tier plan costs for a 59-year-old enrollee in all 50 states and Washington, D.C. The base dataset uses CMS QHP Landscape and Rate Public Use Files and direct State-Based Marketplace filings, validated against CMS and KFF benchmarks within a ±2% margin.

Age-59 premiums were calculated by applying the appropriate age-rating curve ratio to the age-40 base premium for each state. For 48 age-rated states, this is the CMS default curve ratio of 2.037 (displayed as 2.04×). Massachusetts and New Jersey use state-specific age curves established under their 2:1 maximum age-rating laws; the applicable ratio for both states is 2.280 ÷ 1.393 = 1.637, per the CMS State-Specific Age Curve Variations table (last updated 2017 and still in effect for these markets). Utah also has a state-specific curve (3.000 ÷ 1.479 = 2.028); the resulting age-59 premium of $1,582 is shown as 2.04× in the table since the 0.4% difference from the federal default falls within the study's ±2% validation margin. Three jurisdictions use community rating (New York, Vermont and Washington, D.C.); their age-59 premiums equal their age-40 premiums.

Georgia appears in the Medicaid expansion column as 'Yes*', consistent with MoneyGeek's ACA Premiums 2026 analysis, with a footnote noting its limited Pathways to Coverage partial expansion program (approximately 11,600 enrollees; work requirements; 100% FPL ceiling). Wisconsin is footnoted as a partial expansion state covering adults to 100% FPL without the enhanced federal match. Arkansas is a full expansion state using a private option model.

Enrollment figures for the 55 to 64 age cohort are sourced from KFF Health Insurance Marketplace Enrollment Data (5,493,907 enrollees, 22.6% of 24,319,713 total effectuated enrollees). Urban Institute uninsurance projections are sourced from the Urban Institute Health Policy Center's analysis of enhanced premium tax credit expiration scenarios, published December 2025. All premium figures are unsubsidized benchmark Silver-tier premiums; actual enrollee costs depend on income, plan selection and subsidy eligibility.
