How to Save on Health Insurance

1. Check Subsidy Eligibility

Use healthcare.gov or your state marketplace to see if you qualify. Income limits are generous through 2025.

2. Compare All Metal Tiers

Don’t assume Bronze is cheapest overall—if you use healthcare regularly, Gold may cost less after deductibles.

3. Choose In-Network Providers

Out-of-network care can double or triple your costs. Verify provider networks before enrolling.

4. Use HSA-Eligible Plans

If you’re healthy, a Bronze HDHP with HSA allows tax-free savings for future medical expenses.

5. Consider State Programs
