ACA Subsidy Calculator 2026
Find out if you qualify for Affordable Care Act health insurance subsidies in 2026. The enhanced subsidies expired — the 400% FPL cliff is back. Enter your income and family size to see your estimated monthly subsidy, premium after subsidy, and exactly where the cliff hits.
The ACA Subsidy Cliff Is Back in 2026
The Inflation Reduction Act temporarily removed the ACA subsidy cliff from 2021 through 2025, allowing anyone buying marketplace insurance to cap premiums at 8.5% of income regardless of how high their earnings were. That provision has expired. Starting in 2026, if your household income exceeds 400% of the Federal Poverty Level, you receive zero subsidy assistance. For a family of four, that cliff hits at $128,600. Earning even one dollar above that threshold means losing thousands of dollars in annual premium assistance — there is no gradual phase-out above 400% FPL.
How ACA Premium Subsidies Are Calculated
ACA premium tax credits work by capping the percentage of income you spend on a benchmark Silver plan. The government pays the difference between your expected contribution and the actual benchmark plan cost. Your expected contribution percentage scales with income: households at 100-150% FPL pay just 2.0% of income, while those at 300-400% FPL pay 9.86%. The benchmark Silver plan is the second-lowest-cost Silver plan available in your area. If you choose a cheaper Bronze plan, your subsidy stays the same, reducing your out-of-pocket premium further. If you choose a Gold or Platinum plan, you pay the difference above the benchmark.
Federal Poverty Level Thresholds by Family Size
The 2026 Federal Poverty Level determines your subsidy eligibility. For one person, the FPL is $15,650. Each additional household member adds $5,500. For a family of four, the FPL is $32,150, making the 400% cliff threshold $128,600. These numbers are updated annually by the Department of Health and Human Services. Alaska and Hawaii have higher FPL thresholds, but the 48 contiguous states and D.C. share the same levels. Your percentage of FPL is calculated by dividing your modified adjusted gross income by the applicable FPL for your family size.
Subsidy Cliff Visualizer — See the Drop-Off
The cliff visualizer above shows the dramatic impact of the 400% FPL threshold. At 399% FPL, a household still receives a meaningful subsidy that limits premium costs to 9.86% of income. At 401% FPL, the subsidy drops to zero instantly. For a family of four, this means going from roughly $500 or more per month in subsidies to nothing by earning just a few hundred dollars more. This creates a perverse incentive where a small raise can actually cost a family thousands of dollars per year. Understanding exactly where this cliff falls for your family size is essential for financial planning.
Strategies to Stay Below the 400% FPL Threshold
If your income is near the 400% FPL cliff, several legal strategies can help you stay eligible for subsidies. Contributing more to pre-tax retirement accounts like a traditional 401(k) or IRA reduces your modified adjusted gross income. Health Savings Account contributions, if you have an HSA-eligible plan, also lower MAGI. Self-employed individuals can time business deductions strategically. Harvesting investment losses can offset capital gains. Some households choose to maximize pre-tax deductions in years when their income is borderline. The key is understanding that ACA subsidies use MAGI — modified adjusted gross income — which excludes certain pre-tax contributions.
