Missouri Health Insurance Calculator 2026

Missouri uses the federal HealthCare.gov marketplace for ACA health insurance enrollment. During open enrollment (typically November through January), Missouri residents can compare Bronze, Silver, Gold, and Platinum plans and apply for premium tax credits based on household income.

Medicaid in Missouri

Missouri has expanded Medicaid under the Affordable Care Act. This means adults with household income up to 138% of the Federal Poverty Level (about $20,783 for a single person in 2025) may qualify for Medicaid coverage with little or no premium cost. If your income is above this threshold, you can check for ACA marketplace subsidies using the calculator above.

Premium Subsidies in Missouri

ACA premium tax credits are available to Missouri residents with household income between 100% and 400% of the Federal Poverty Level. The subsidy amount is based on the cost of the benchmark Silver plan in your area minus your expected contribution (a percentage of your income). You can apply subsidies in advance to lower your monthly premium or claim them when you file your federal tax return.

The actual premiums and plan options available in Missouri vary by county and rating area. Factors that affect your premium include age, tobacco use, household size, and zip code. Use the calculator above for a general estimate, then check HealthCare.gov for exact plan pricing in your area.
