Health Insurance Subsidy Calculator
Estimate your potential premium tax credit (subsidy) for health insurance purchased through the Affordable Care Act (ACA) marketplace. This calculator uses current Federal Poverty Level (FPL) guidelines and the enhanced subsidy rules from the Inflation Reduction Act (IRA) of 2022, which are in effect through 2025.
This is the annual cost of the second-lowest-cost Silver plan available to your household in your area. You can find this on your state's marketplace website or Healthcare.gov.

Understanding Health Insurance Subsidies
Health insurance subsidies, officially known as Premium Tax Credits (PTCs), are a crucial component of the Affordable Care Act (ACA). They help make health insurance coverage more affordable for individuals and families who purchase plans through the Health Insurance Marketplace (also known as the exchange) in their state or via Healthcare.gov.
How Subsidies Work
The core idea behind subsidies is to limit the percentage of your household income that you have to spend on health insurance premiums. If the cost of a benchmark plan (typically the second-lowest-cost Silver plan available in your area) exceeds this percentage, the government pays the difference directly to your insurance company, reducing your monthly premium.
Key Factors for Eligibility and Amount:
- Household Income (Modified Adjusted Gross Income – MAGI): This is the primary factor. Your MAGI is generally your adjusted gross income (AGI) plus certain tax-exempt interest and foreign income. The lower your MAGI relative to the Federal Poverty Level, the larger your potential subsidy.
- Household Size: The Federal Poverty Level (FPL) varies based on the number of people in your tax household. A larger household size means a higher FPL threshold, which can make you eligible for more assistance at the same income level.
- Federal Poverty Level (FPL): The FPL is a set of income thresholds used by the federal government to determine eligibility for various programs. Subsidies are calculated based on your income as a percentage of the FPL for your household size.
- Benchmark Plan Cost: The actual dollar amount of your subsidy depends on the cost of the second-lowest-cost Silver plan in your specific geographic area. This cost varies significantly by state, county, and even age. The subsidy covers the difference between this benchmark plan's cost and the maximum amount you're expected to pay based on your income.
- Enrollment through the Marketplace: To receive a subsidy, you must purchase a health plan through your state's official ACA marketplace or Healthcare.gov.
- Not Eligible for Other Coverage: Generally, you cannot receive a subsidy if you are eligible for affordable coverage through an employer (including your spouse's employer) or government programs like Medicare or Medicaid.
The Impact of the Inflation Reduction Act (IRA) of 2022
The IRA significantly enhanced ACA subsidies, making them more generous and expanding eligibility. Crucially, it temporarily removed the "subsidy cliff" for those earning above 400% of the FPL. This means that no one pays more than 8.5% of their household income for the benchmark Silver plan, regardless of how high their income is. These enhanced subsidies are currently in effect through 2025.
How to Use This Calculator
To get an estimate, you'll need:
- Estimated Annual Household Income (MAGI): This is your best guess for your Modified Adjusted Gross Income for the year you need coverage.
- Household Size: The number of people in your tax household.
- Estimated Annual Benchmark Plan Cost: This is the most variable input. You can find this by visiting Healthcare.gov or your state's marketplace website, entering your basic information (zip code, household size, ages), and looking for the cost of the second-lowest-cost Silver plan. This calculator uses this cost to determine the actual dollar amount of your subsidy.
Remember, this calculator provides an estimate. Your actual subsidy will be determined by the Marketplace based on your application and the specific plans available in your area.
