COBRA vs ACA in Washington: which costs less?
In Washington the average benchmark Marketplace plan for a 40-year-old costs $612 a month in 2026 before any credit, $13 below the $625 national average. Washington expanded Medicaid, so very low incomes may qualify for it. Whether COBRA or the Marketplace costs you less depends on your income for the year.

What a single adult would pay in Washington
Coverage in 2026, the $612 benchmark plan and the IRS table. Estimates; the calculator takes your own numbers.
| Yearly income | Poverty line | Expected share | Credit a month | You pay a month |
|---|---|---|---|---|
| $23,475 | 150% | 4.2% | $530 | $82 |
| $39,125 | 250% | 8.4% | $337 | $275 |
| $54,775 | 350% | 10.0% | $157 | $455 |
| Over $62,600 | Over 400% | none | $0 | $612 |
The benchmark plan rose $178 a month ($2,136 a year) from 2025 to 2026. People under the 400% line were not charged for that: their credit grew to cover it. People above it paid it all. For 2027 coverage the line moves to $63,840 for one person, where a credit of about $68 a month would still be lost if the 2026 benchmark price held.

Questions about COBRA vs ACA in Washington
- Is the ACA Marketplace cheaper than COBRA in Washington?
- It is if your income is low enough for a premium tax credit. In Washington the average benchmark plan for a 40-year-old costs $612 a month in 2026 before any credit. A single adult at 150% of the poverty line ($23,475 a year) would pay about $82 a month for it after the credit; at 350% ($54,775) about $455. Above $62,600 there is no credit and the plan costs its full price. Compare with the COBRA premium on your own notice.
- What does crossing the 400% line cost in Washington?
- For a single adult with 2026 coverage, earning one dollar over $62,600 removes a credit of about $92 a month ($1,109 a year) on the $612 benchmark plan. For 2027 coverage the line moves to $63,840.
