ACA Health Insurance Subsidy Calculator 2026
About the ACA Subsidy Calculator
The Affordable Care Act (ACA) provides premium tax credits to help eligible Americans afford health insurance through the Health Insurance Marketplace. Your subsidy amount is based on your household income as a percentage of the Federal Poverty Level (FPL). For 2026, the FPL baseline is $15,650 for a single person, increasing by $5,590 for each additional household member. Households earning between 100% and 400% FPL may qualify for premium tax credits, also known as Advanced Premium Tax Credits (APTC). The credit caps your contribution toward the benchmark silver plan at a percentage of your income, ranging from 0% at 150% FPL to 8.5% at 300-400% FPL. If you live in a state that expanded Medicaid, households earning under 138% FPL may qualify for Medicaid instead of marketplace subsidies. Use this calculator to estimate your potential savings before shopping on Healthcare.gov during Open Enrollment.
Frequently Asked Questions
Who qualifies for ACA subsidies in 2026?
Individuals and families with household income between 100% and 400% of the Federal Poverty Level who purchase coverage through the Marketplace and are not eligible for affordable employer coverage, Medicare, or Medicaid may qualify for premium tax credits.
What is the income limit for ACA subsidies?
For 2026, the general upper limit is 400% FPL, which is approximately $62,600 for a single person. However, the American Rescue Plan Act provisions have extended subsidies above 400% FPL in some cases — those paying more than 8.5% of income for the benchmark plan may still receive credits.
How are ACA subsidies calculated?
The subsidy equals the cost of the benchmark silver plan minus a capped percentage of your income. The cap ranges from 0% at lower income levels to 8.5% at higher income levels, ensuring you never pay more than that percentage of your income for the benchmark plan.
Can I receive ACA subsidies if my employer offers insurance?
Generally no, unless your employer's plan is deemed unaffordable (costs more than 9.02% of household income for employee-only coverage in 2026) or fails to meet minimum value standards.
What is the difference between APTC and PTC?
Advanced Premium Tax Credit (APTC) is paid directly to your insurer each month to reduce your premium. The Premium Tax Credit (PTC) is reconciled on your tax return via Form 8962. If your actual income differs from your estimate, you may owe money back or receive a refund.
