Quick answer
The 2026 national benchmark Marketplace plan for a 50-year-old runs about $873 a month before any tax credit, a jump of nearly 40% from age 40 alone. With a premium tax credit, someone earning $40,000 would still 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 $873. At 55, you also become eligible for an extra HSA catch-up contribution if you’re on a high-deductible plan.
Key takeaways
- A 50-year-old’s 2026 benchmark plan averages about $873 a month nationally, up almost 40% from the $625 benchmark at 40.
- The federal age curve steepens as you get older: the jump from 40 to 50 is bigger than the jump from 21 to 30, and the jump from 50 to 60 is bigger still.
- A premium tax credit can cut the bill a lot at lower incomes. Above 400% of the poverty level, you pay full price, and that jump is much bigger at 50 than at younger ages.
- At 55, you can add a $1,000 HSA catch-up contribution on top of the regular limit if you’re enrolled in a qualifying high-deductible plan.
- The 2027 HSA contribution limit is $4,500 for self-only coverage and $9,000 for family coverage, both up modestly from 2026.

What a 50-year-old pays before subsidies
Scaling KFF’s 2026 national benchmark premium ($625 a month for a 40-year-old) up to age 50 with the federal age curve puts the benchmark silver plan at about $873 a month before any tax credit.
| Age | Full-price benchmark plan, per month (2026 estimate) |
|---|---|
| 21 | $489 |
| 30 | $555 |
| 40 | $625 |
| 50 | $873 |
| 60 | $1,327 |
| 64 | $1,467 |
Why costs climb faster after 50
The federal age curve isn’t a straight line. Going from 21 to 30 adds about 14% to the price. Going from 40 to 50 adds almost 40%. Going from 50 to 60 adds more than 50% on top of that. Each decade past 40 costs proportionally more than the one before it, which is why people in their 50s often feel like their premium jumped overnight even when nothing else about their coverage changed.
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% | $873 |
At 50, crossing that 400% line adds about $329 a month to the bill. At $63,840 you’d pay about $544 with the credit, and a dollar more means paying the full $873. That’s a much bigger swing than the same cliff produces at 30 or 40. See how to lower your Marketplace premium if you’re close to that line and want to manage it.
HSA catch-up contributions start at 55
If you’re on a bronze, catastrophic or other qualifying high-deductible plan, an HSA lets you set aside pre-tax money for medical costs. The regular contribution limit is $4,400 for self-only coverage in 2026, rising to $4,500 in 2027. Once you turn 55, you can add an extra $1,000 catch-up contribution on top of whichever limit applies that year, and that extra room stays available every year after until you enroll in Medicare.
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 prices coverage the same at every age. New York does the same: its $817 benchmark doesn’t change with age either. Most other states, including the national figures above, scale price by age. Virginia’s guide shows how one mid-priced state compares, and how rates get set generally covers the county-level factors behind these averages.
Health insurance costs at other ages: 26, 30, 40, 60 and 64, plus couples.
