How It Works
Uses ACA premium tax credit formulas: your expected contribution is based on a sliding scale of 2-8.5% of household income (varies by poverty level). The subsidy = the benchmark silver plan premium minus your expected contribution. Results show estimated credit and net premium costs for metal tiers.
Real-World Example

- Household income: $55,000 (297% of FPL).
