• Premium vs. total cost: The average premium of $498/month is near the national average.

Cost-Saving Tips for Missouri Residents

To minimize your health insurance costs in Missouri:

1. Always check your subsidy eligibility on healthcare.gov before assuming you cannot afford coverage.
2. If your income is below 250% FPL, choose a Silver plan to get cost-sharing reductions that reduce your deductible and copays.
3. Compare plans from all 5 available insurers, as premiums can vary significantly for similar coverage levels.
4. Consider an HDHP with HSA if you are healthy and want to build tax-advantaged medical savings.
5. Check if your state offers any additional premium assistance programs beyond federal subsidies.
