How to Find the Cheapest Health Insurance in Colorado
Shopping for health insurance can feel daunting with countless options featuring different premiums, coverage levels and deductibles. These steps will help you find affordable coverage that covers your healthcare needs affordably.
- 1Choose a plan type within your budget
Your health circumstances and income determine which type of plan and metal tier work best. Calculate your monthly premium budget, assess your current health status and evaluate your injury or illness risk based on age, location and lifestyle.
- 2Check if you qualify for subsidies
Your household income and size determine eligibility for 2026 health insurance subsidies. Subsidies apply to incomes between 100% and 400% of the Federal Poverty Level (FPL). Lower incomes receive larger subsidies, with credit amounts decreasing as income rises.
- 3Explore Medicare options if you qualify
Medicare, Medicaid, Medicare Advantage plans and Medicare Supplement plans cost less than marketplace coverage. Compare eligibility requirements and benefits for each program.
- 4Verify prescription coverage
Check which tier your medications fall under for each insurer. Some plans place common prescriptions on lower tiers with smaller copays, potentially saving you hundreds annually.
- 5Shop during Open Enrollment period
Open Enrollment runs from November 1 to January 15. You may qualify for Special Enrollment if you've lost your job, divorced or had a child. Compare coverage types, customer ratings, costs and whether your doctors accept the plan.
- 6Review Colorado-specific requirements
Colorado has unique insurance regulations that may affect your coverage options. Research state-mandated benefits, network requirements and any additional protections available to residents. Understanding local rules helps you make informed decisions about your health insurance purchase.
Cheapest Health Insurance in Colorado: Bottom Line
Kaiser Permanente, Denver Health Medical Plan and Select Health offer Colorado's lowest health insurance rates. Compare quotes from at least three insurers across multiple metal tiers to match your budget and coverage needs.

How We Decided the Cheapest Health Insurance Companies in Colorado
Colorado offers hundreds of health insurance plans, and premiums vary by age. We analyzed rate data from Connect for Health Colorado, the state's health insurance marketplace, to identify which insurers offer the lowest premiums for different demographics.
Our Analysis Approach
We collected plan data for consumers aged 18, 26, 40, 50 and 60 to cover the full age spectrum from teens through pre-Medicare seniors. We ranked providers by their average monthly premiums for 40-year-olds as our baseline "cheapest overall" category, since this age reflects Colorado's median health insurance consumer and provides the most relevant comparison for most shoppers.
For age-specific rankings (teens, young adults, adults, seniors), we used the corresponding ages listed above. This approach reveals which insurers offer the best rates for your specific age group, not just generic "cheapest" rankings that may not apply to you.
Important Cost Tradeoff
Bronze and Silver plans (the lowest monthly premiums) charge $3,400 to $7,633 deductibles and $9,700 to $10,400 maximum out-of-pocket costs. You'll save monthly but pay more when you need care. Compare premiums and potential out-of-pocket expenses based on your expected medical usage.
