Quick answer
Researchers use a 40-year-old as the standard for comparing ACA premiums, so the 2026 national benchmark plan for a 40-year-old is KFF’s published average: $625 a month before any tax credit. With a premium tax credit, someone earning $40,000 would pay around $289 a month for that plan in 2027; above 400% of the poverty level, about $63,840 for one person, you’d owe the full $625. Add a spouse and two young kids at the benchmark rate and the household’s full price runs close to $1,998 a month before subsidies.
Key takeaways
- Forty is the standard age for comparing ACA premiums, so KFF’s $625 national average for 2026 is the 40-year-old figure.
- A premium tax credit can cut that a lot at lower incomes. Above 400% of the poverty level ($63,840 for one person in 2027), you pay full price.
- A family of four with two 40-year-old parents and two young children would face a full price near $1,998 a month in 2026, before any tax credit.
- Cost-sharing reductions can lower deductibles and copays further if household income is under 250% of the poverty level, on a silver plan.
- The out-of-pocket maximum is $10,600 for one person in 2026 and rises to $12,000 in 2027, the most you’d pay in a year on top of the premium.

Why 40 is the reference age
When you see a headline number like “the national average benchmark premium,” it’s usually a 40-year-old’s price, because KFF and other researchers use 40 as the standard age for comparing plans across states and years. KFF’s 2026 average benchmark premium, $625 a month, is a 40-year-old’s price by definition. Every other age in this article is that same $625 scaled up or down using the federal government’s default age curve.
| Age | Full-price benchmark plan, per month (2026 estimate) |
|---|---|
| 21 | $489 |
| 30 | $555 |
| 40 | $625 |
| 50 | $873 |
| 60 | $1,327 |
| 64 | $1,467 |
What you’d pay after a premium tax credit for 2027
The premium tax credit caps what you owe for the benchmark plan at a share of your income, using a federal poverty level of $15,960 for one person (2027 coverage uses the 2026 guidelines).
| Yearly income | % of poverty level | What you’d pay per month |
|---|---|---|
| $25,000 | 157% | $96 |
| $40,000 | 251% | $289 |
| $60,000 | 376% | $511 |
| $70,000 | 439% | $625 |
Crossing that 400% line costs a 40-year-old about $81 a month. At $63,840 you’d pay about $544 with the credit, and a dollar more means paying the full $625.

Covering a family at 40
The federal age curve rates a child under 15 at about 0.6 times a 40-year-old’s price, and only the three oldest children under 21 in a household are charged at all. Two 40-year-old parents plus two young children would face a full price near $1,998 a month nationally in 2026, before any tax credit is applied. A household’s premium tax credit works the same way as an individual’s: it’s based on the family’s combined benchmark price, household income and family size. See how much a family of four typically pays and the broader options in family health insurance for more on covering dependents.
Costs beyond the premium
The premium is only part of the bill. A plan’s deductible, copays and coinsurance add up until you hit the out-of-pocket maximum, which is $10,600 for one person in 2026 and rises to $12,000 in 2027. If household income is under 250% of the poverty level, a silver plan also comes with cost-sharing reductions, which lower the deductible and copays directly rather than just the premium.
Why your state changes the price
KFF’s 2026 numbers put the benchmark plan as low as $401 a month in New Hampshire and as high as $1,299 in Vermont, which doesn’t vary price by age at all. New York also prices by community rating, so its $817 benchmark is the same at every age. Most other states, including the national figures used above, scale price by age the way this article shows. California’s guide and how rates get set generally are good next reads if you want the county-level detail behind these averages.
Health insurance costs at other ages: 26, 30, 50, 60 and 64, plus couples.

Frequently asked questions
How much does health insurance cost for a 40-year-old?
The 2026 national benchmark plan for a 40-year-old runs $625 a month before subsidies, which is the figure most “national average” headlines are actually quoting.
Why is 40 used as the reference age for health insurance prices?
Researchers needed one consistent age to compare premiums across states and years, and 40 became the usual standard. Prices at other ages can be estimated by scaling that benchmark with the federal age curve.
How much would a family of four pay at 40?
Two 40-year-old parents and two young children would face a full price near $1,998 a month nationally in 2026, before any tax credit reduces it.
What’s the out-of-pocket maximum for 2027?
It’s $12,000 for one person and $24,000 for a family, up from $10,600 and $21,200 in 2026. That’s the most you’d pay in deductibles, copays and coinsurance combined in a year.
