How Much Is Health Insurance in Washington State?

By James Shaffer, insurance professional

Quick answer

In 2026, the benchmark silver plan on Washington Healthplanfinder averaged $612 a month for a 40-year-old before subsidies, close to the U.S. average of $625. Prices rise with age, from about $479 a month at 21 to $1,300 at 60. Many enrollees get a federal tax credit, and Washington adds its own Cascade Care Savings for lower incomes. For 2027, the state approved an average increase of 22.2%.

Key takeaways

  • Washington’s 2026 benchmark premium for a 40-year-old was about $13 below the national average.
  • About 290,000 people picked a plan for 2026, and 64% got a federal premium tax credit.
  • Regulators approved an average 22.2% increase for 2027, from 6.7% to 30.5% depending on the insurer.
  • Cascade Care Savings, Washington’s own subsidy, may help households with incomes up to 250% of the poverty level.
  • Open enrollment runs from November 1, 2026 to January 15, 2027. Sign up by December 31 for coverage starting January 1.

A family of four with two 40-year-old parents and two young children would pay about $1,956 a month for benchmark plans before subsidies.

What you’d pay after a tax credit

If your household income is between 100% and 400% of the federal poverty level, a premium tax credit caps what you pay for the benchmark plan at a share of your income. A single 40-year-old in Washington earning $40,000 would pay about $287 a month for the benchmark plan in 2026, with a federal tax credit of about $325. For 2027, the same person’s federal share would be about $289 a month. Above 400% of the poverty level ($62,600 for one person for 2026 coverage, $63,840 for 2027), you’d pay full price.

Cascade Care Savings

Washington adds its own premium help for people with incomes up to 250% of the poverty level who buy a silver or gold Cascade Care plan through Washington Healthplanfinder. In 2026, it was $55 per person per month for most enrollees with incomes up to 250% of the poverty level, less than in 2025, and larger for people who can’t get federal tax credits. The state says it may still be available for 2027 to households up to 250% of the poverty level.

Costs beyond the premium

What you pay when you get care depends on your plan’s deductible, copays and coinsurance, up to the out-of-pocket maximum of $10,600 for one person in 2026 ($12,000 in 2027). If your income is under 250% of the poverty level, a silver plan’s cost-sharing reductions lower those costs.
