Over 400% FPL? Start here

ACA Subsidy Calculator Hub: Check Your Subsidy, Then Compare Alternatives

Quick answerRun the calculator below. If your income is under 400% FPL, ACA subsidies likely make the Marketplace your strongest option. If you're over 400% FPL, reasonably healthy, tobacco-free, with no pending procedures and no significant medical history, you may qualify for a significantly lower premium through an alternative — the 31 guides below show you how.

You likely qualify for premium tax credits (APTC). At 213% FPL, your expected contribution toward the benchmark silver plan is about 7.26% of income under the official 2027 table (IRS Rev. Proc. 2026-26) — the rest becomes a subsidy. Households under 250% FPL also qualify for cost-sharing reduction (CSR) silver plans with lower deductibles and copays.

Estimate only. Uses the 2026 HHS poverty guidelines and the official 2027 applicable percentage table (IRS Rev. Proc. 2026-26) for plan year 2027. Final eligibility is determined by the Marketplace using verified MAGI.

The 400% FPL cliff, in dollars

For 2026 coverage, the subsidy cliff is back: above roughly these income levels, the premium tax credit drops to zero and you pay the full ACA premium.

How your ACA subsidy is calculated

The premium tax credit works the same way in every state, including Texas. Three numbers decide it:

  1. Your household income (MAGI). Modified Adjusted Gross Income — roughly your adjusted gross income plus tax-exempt interest and untaxed Social Security. You estimate it for the coverage year when you apply.
  2. Your Federal Poverty Level percentage. Your income divided by the HHS poverty guideline for your household size. The table above shows where that line falls for 2026 coverage.
  3. The benchmark silver plan in your county. Your credit equals the cost of the second-lowest-cost silver plan where you live, minus the percentage of income the federal formula expects you to contribute. A higher local benchmark means a larger credit.

This page estimates; it does not determine eligibility. Your final credit is calculated by HealthCare.gov when you submit an application, and reconciled on your federal tax return (IRS Form 8962).
