Health Insurance Cost in Illinois
Health insurance premiums in Illinois vary by household size and plan type. Single coverage averages $490, while family plans average $1,350 monthly. These estimates are based on marketplace (ACA) plans and reflect benchmark Silver-tier premiums before subsidies. Your actual cost may be lower if you qualify for premium tax credits.
How to Interpret These Premium Ranges
The premiums shown below represent the range of costs you might encounter when shopping for health insurance in Illinois. The low end typically reflects Bronze plans in less expensive rating areas or younger age groups. The high end represents Gold or Platinum plans in urban areas or for older enrollees (premiums can be up to 3x higher for a 64-year-old compared to a 21-year-old under ACA rules).
Important: Most marketplace enrollees pay significantly less than the full premium thanks to premium tax credits. In 2025, approximately 90% of marketplace enrollees receive subsidies. Check your potential savings on the Illinois ACA subsidy examples page.

Tips to Reduce Health Insurance Costs in Illinois
Check Your Subsidy Eligibility
Most people who buy through the marketplace qualify for premium tax credits. Use the official calculator at HealthCare.gov to see if you can get a lower premium.
Compare Plan Tiers Carefully
A Bronze plan has the lowest premium but the highest deductible. If you expect regular medical care, a Silver or Gold plan may cost less overall despite the higher monthly payment.
Consider Silver Plans for CSR
If your income is 100-250% FPL, Silver plans offer Cost-Sharing Reductions that dramatically lower your deductible and copays—savings only available on Silver-tier plans.
Shop During Open Enrollment
Plans and prices change every year. Even if you're happy with your current plan, compare options annually during Open Enrollment (November 1 – January 15) to ensure you have the best deal.

Frequently Asked Questions
What is the average health insurance cost in Illinois?
The average monthly health insurance premium in Illinois is approximately $490 for a single person, $980 for a couple, and $1,350 for a family of four. These are full-price (pre-subsidy) estimates based on Silver-tier marketplace plans. Most enrollees pay significantly less after applying premium tax credits.
What is the difference between Bronze, Silver, Gold, and Platinum plans?
These "metal tiers" indicate how costs are shared between you and the insurer. Bronze plans have the lowest monthly premiums but highest out-of-pocket costs (you pay ~40% of care). Silver plans split costs roughly 70/30 and qualify for Cost-Sharing Reductions (CSR) at lower incomes. Gold plans cover ~80% of costs. Platinum plans cover ~90% but have the highest premiums. All tiers cover the same essential health benefits.
How can I get cheaper health insurance in Illinois?
In Illinois, the most effective way to reduce premiums is through ACA premium tax credits available at Get Covered Illinois. If your household income is between 100-400% of the Federal Poverty Level (or higher under current enhanced subsidies), you likely qualify. Other strategies include choosing a higher-deductible plan, using an HSA-eligible plan to save on taxes, and comparing plans from all available carriers including Blue Cross Blue Shield of Illinois and Ambetter.
What does health insurance actually cover?
All ACA-compliant plans must cover 10 Essential Health Benefits: hospitalization, outpatient care, emergency services, maternity/newborn care, mental health services, prescription drugs, rehabilitative services, lab services, preventive care (at no cost), and pediatric services including dental and vision for children. Preventive services like annual check-ups, vaccinations, and screening tests are free on all marketplace plans.
What if I can't afford health insurance in Illinois?
If your income is below 138% of the Federal Poverty Level, you may qualify for Medicaid (HFS) (Illinois's Medicaid program), which provides free or very low-cost coverage. If you earn too much for Medicaid but still find marketplace plans expensive, check for premium tax credits at Get Covered Illinois. You may also explore short-term plans, health sharing ministries, or community health centers that provide care on a sliding-scale fee basis.
