How the ACA Subsidy Calculator Works
The Affordable Care Act (ACA) provides premium tax credits to help eligible individuals and families afford health insurance purchased through the Health Insurance Marketplace. This calculator estimates your 2026 subsidy using the official ACA formula that returns after the American Rescue Plan Act (ARPA) enhanced subsidies expire at the end of 2025.
Where your Expected Contribution equals your household income multiplied by an applicable percentage that increases with income. The benchmark premium is the cost of the second-lowest-cost Silver plan (SLCSP) in your area, adjusted for the ages of the people in your household.
What Changed in 2026
Under the ARPA (2021-2025), nobody paid more than 8.5% of income for the benchmark plan, and people below 150% FPL paid nothing. In 2026, required contributions increase significantly: families at 150% FPL now pay up to 4% of income, and the 400% FPL subsidy cliff returns — meaning if your income exceeds 400% of the Federal Poverty Level, you get zero subsidy regardless of how expensive premiums are.
Key Income Thresholds for 2026
Below 138% FPL (Medicaid expansion states): Likely eligible for Medicaid, not marketplace subsidies
100% - 150% FPL: Smallest required contributions; eligible for the best Cost-Sharing Reductions (94% AV Silver plan)
150% - 250% FPL: Moderate contributions with some Cost-Sharing Reductions
250% - 400% FPL: Higher contributions but still subsidy-eligible
Above 400% FPL: No subsidy available (the "subsidy cliff")
Frequently Asked Questions
What is the ACA subsidy cliff?
The ACA subsidy cliff is the income threshold at 400% of the Federal Poverty Level where marketplace subsidies completely cut off. In 2026, if your household income exceeds 400% FPL (e.g., $62,600 for a family of 4), you receive zero premium tax credit — even if you're just $1 over the limit. This cliff was temporarily eliminated by the American Rescue Plan Act (2021-2025), which capped contributions at 8.5% of income for all income levels. With the return of the cliff in 2026, families near the threshold should carefully manage their Modified Adjusted Gross Income (MAGI) through strategies like traditional IRA or HSA contributions.
What happened to the enhanced subsidies?
The American Rescue Plan Act (ARPA) of 2021 significantly boosted ACA subsidies by lowering the percentage of income people had to pay toward premiums and eliminating the 400% FPL subsidy cliff. Under ARPA, people below 150% FPL paid $0, and nobody paid more than 8.5% of income. These enhanced subsidies were extended through 2025 by the Inflation Reduction Act. However, Congress did not extend them further, so in 2026 the original ACA subsidy formula returns. For a family of 4 earning $80,000, this could mean thousands of dollars more in annual premiums compared to what they paid in 2025.
Am I eligible for Medicaid instead?
If your income is below 138% of the Federal Poverty Level and you live in one of the 41 states (plus DC) that have expanded Medicaid, you likely qualify for Medicaid instead of marketplace subsidies. Medicaid provides free or very low-cost coverage. In the 10 states that have not expanded Medicaid (Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, and Wyoming), adults with income below 100% FPL may fall into the "coverage gap" — they earn too much for traditional Medicaid but too little for marketplace subsidies. Wisconsin is a special case: it covers adults up to 100% FPL without formal expansion.
What is the benchmark Silver plan?
The Second Lowest Cost Silver Plan (SLCSP) is the plan used to calculate your premium tax credit. It's the second-cheapest Silver-tier plan available in your rating area. Your subsidy equals the SLCSP premium minus your expected contribution based on income. You can apply your subsidy to any marketplace Metal tier — Bronze, Silver, Gold, or Platinum. Choosing a Bronze plan (with lower premiums) might result in a $0 monthly cost after the subsidy. Choosing a Gold or Platinum plan means you'd pay the difference between that plan's premium and your subsidy amount.
How accurate is this calculator?
This calculator uses the official 2026 Federal Poverty Level guidelines, the standard ACA applicable percentage table, federal age curve rating factors, and state-average benchmark premiums. Because premiums vary by county and rating area, the benchmark premiums used here are statewide averages and may differ from your exact location. For the most accurate subsidy amount and to see actual plan options, visit healthcare.gov during Open Enrollment and enter your specific ZIP code and household information.
What are Cost-Sharing Reductions?
Cost-Sharing Reductions (CSRs) lower your out-of-pocket costs — deductibles, copays, and coinsurance — when you enroll in a Silver plan through the marketplace. CSRs are available to households with income between 100% and 250% of FPL. Below 150% FPL, you get a Silver plan that covers about 94% of your healthcare costs (vs. the standard 70%). Between 150-200% FPL, the plan covers about 87%. Between 200-250% FPL, about 73%. CSRs are only available on Silver plans, which is why Silver is often the best value for lower-income households even if a Bronze plan has a lower premium.
