Example Calculation
Household Profile

- Household size: 3
- State: Illinois
- Ages: 35, 34, 8
Step 1: Determine FPL
For a family of 3, 2026 FPL ≈ $25,100
Step 2: Income as % of FPL
$45,000 ÷ $25,100 ≈ 179% of FPL
Step 3: Estimate Premium Tax Credit
Based on 179% of FPL, the premium tax credit could reduce monthly premiums by approximately $400.
Step 4: Cost-Sharing Reductions
Eligible for certain plans (silver tier) with reduced deductibles and out-of-pocket maximums.
Step 5: Monthly Premium After Subsidy
