Example calculation
Plug in your own numbers and the result updates instantly. FPL percent = income / poverty guideline. Estimated PTC = benchmark premium - expected income contribution.
How this calculator estimates the result
The calculator computes your household income as a percentage of the federal poverty level (FPL) for your household size, looks up the applicable percentage of income you are expected to contribute toward a benchmark Silver plan, then subtracts that expected contribution from the benchmark premium. The difference, floored at zero, is your estimated annual Premium Tax Credit. Dividing by 12 gives the estimated monthly credit you can apply in advance to lower your premium.
Assumptions baked in
- Applicable percentages from the ARPA/IRA contribution schedule in effect for the plan year.
- Benchmark = the second-lowest-cost Silver plan available to your household in your rating area.
- Modified Adjusted Gross Income (MAGI) is used, not gross wages.
- Household size matches your tax household for the coverage year.
- No employer offer of affordable, minimum-value coverage is available.
What this calculator does not do
- Does not check Medicaid or CHIP eligibility, which replaces Marketplace subsidies at lower incomes in expansion states.
- Does not apply Cost-Sharing Reductions (CSRs), which only reduce deductibles and copays on Silver plans for incomes up to 250% FPL.
- Does not account for the family glitch fix details, COBRA, retiree coverage, or Marketplace eligibility rules for immigrants.
- Benchmark premiums vary by ZIP code, age, and tobacco use; this tool uses the value you enter.
A step-by-step example
Scenario: Household of 3, MAGI $60,000, benchmark Silver premium $1,100/month, 2026 FPL for household of 3 ≈ $26,650.
- FPL % = $60,000 / $26,650 ≈ 225%.
- Applicable contribution percentage at 225% FPL ≈ 4.0% of income.
- Expected annual contribution = 4.0% × $60,000 = $2,400.
- Annual benchmark premium = $1,100 × 12 = $13,200.
- Estimated annual PTC = $13,200 − $2,400 = $10,800.
Result: Estimated monthly Premium Tax Credit ≈ $900. The household pays about $200/month for the benchmark Silver plan, or less for a cheaper Bronze/Silver option.
