ACA Subsidy Calculator

Use this calculator to estimate your potential Affordable Care Act (ACA) premium tax credits, also known as subsidies. These subsidies help reduce the cost of your monthly health insurance premiums purchased through the Health Insurance Marketplace.

This is the annual cost of the second-lowest cost silver plan available in your area through the Marketplace. You can find this on healthcare.gov or your state's exchange website.

Understanding ACA Subsidies (Premium Tax Credits)

The Affordable Care Act (ACA), often referred to as Obamacare, aims to make health insurance more accessible and affordable for millions of Americans. A key component of this is financial assistance in the form of premium tax credits, also known as subsidies.

What are Premium Tax Credits?

Premium tax credits are government subsidies that reduce the amount you pay each month for health insurance premiums purchased through the Health Insurance Marketplace (healthcare.gov or your state's exchange). They are designed to lower your out-of-pocket costs for health coverage, making it more affordable for individuals and families.

Who is Eligible?

Eligibility for premium tax credits primarily depends on two factors:

  1. Household Income: Your Modified Adjusted Gross Income (MAGI) must fall within a certain range relative to the Federal Poverty Level (FPL). Historically, this was between 100% and 400% of the FPL. However, with the Inflation Reduction Act (IRA) of 2022, the "subsidy cliff" at 400% FPL was eliminated through 2025, meaning more people above 400% FPL can now qualify for assistance, capping their premium contributions at 8.5% of their income.
  2. Household Size: The FPL thresholds are adjusted based on the number of people in your household.
  3. Marketplace Enrollment: You must enroll in a health insurance plan through your state's Health Insurance Marketplace or healthcare.gov.
  4. Other Coverage: You generally cannot be eligible for affordable coverage through an employer or government programs like Medicare or Medicaid.

How are Subsidies Calculated?

The calculation of your premium tax credit involves several steps:

  1. Federal Poverty Level (FPL) Determination: Your annual household income is compared to the FPL for your household size. The FPL is a set of income thresholds published annually by the Department of Health and Human Services.
  2. Income Contribution Percentage: Based on your income's percentage of the FPL, the ACA sets a maximum percentage of your income that you are expected to contribute towards your health insurance premiums. This is a sliding scale – the lower your income relative to the FPL, the smaller the percentage of your income you're expected to pay.
  3. Benchmark Plan Cost: The subsidy is calculated based on the cost of the "second-lowest cost silver plan" available in your specific geographic area through the Marketplace. This is known as the benchmark plan.
  4. Subsidy Amount: Your premium tax credit is the difference between the cost of the benchmark silver plan and the maximum amount you're expected to pay based on your income. If the benchmark plan costs less than your expected contribution, you would not receive a subsidy.

Important Considerations:

  • FPL Changes Annually: The Federal Poverty Level guidelines are updated each year, typically in January.
  • Location Matters: FPL guidelines are different for Alaska and Hawaii due to higher costs of living. Benchmark plan costs also vary significantly by location.
  • Income Changes: If your income or household size changes during the year, you must update your information with the Marketplace to ensure your subsidy is accurate. Significant changes could lead to owing money back at tax time or missing out on additional assistance.
  • Cost-Sharing Reductions (CSRs): In addition to premium tax credits, individuals and families with incomes up to 250% of the FPL may also qualify for Cost-Sharing Reductions (CSRs). These reduce your out-of-pocket costs like deductibles, copayments, and coinsurance. CSRs are automatically applied if you choose a silver plan and qualify.

This calculator provides an estimate based on the most recent FPL data for contiguous states and the current ACA rules. For a precise determination of your eligibility and subsidy amount, you should visit healthcare.gov or your state's health insurance marketplace.
