Understanding ACA Subsidies
Navigate the Healthcare Marketplace
The Affordable Care Act (ACA) provides Premium Tax Credits to make health insurance affordable for individuals and families earning between 100% and 400% of the Federal Poverty Level.
Premium Tax Credit (PTC)
Advance or Year-End: Take subsidy monthly (advance) or claim when filing taxes.
Income-Based: For 2026 you are expected to pay about 2.10% to 9.96% of income toward the benchmark Silver plan; the credit covers the rest.
Cliff Is Back: The enhanced subsidies expired after 2025, so for 2026 coverage households above 400% FPL get no premium tax credit. Check HealthCare.gov in case Congress changes the law.
Cost-Sharing Reductions (CSR)
100-150% FPL: 94% Actuarial Value (lower deductibles/copays)
150-200% FPL: 87% Actuarial Value
200-250% FPL: 73% Actuarial Value
Must choose Silver plan to receive CSR benefits.

Why use this?
Health insurance is often the biggest barrier to self-employment and entrepreneurship. Understanding ACA subsidies can make the difference between affording coverage or going uninsured. This calculator helps freelancers, early retirees, and families determine exact subsidy amounts before leaving employer coverage.
How it works
We calculate your household's Federal Poverty Level percentage, then apply the ACA's sliding scale formula to determine Premium Tax Credits. The calculator factors in your state's Medicaid expansion status, benchmark Silver plan premiums, and Cost-Sharing Reduction eligibility.

Frequently Asked Questions
How do I calculate my ACA subsidy?
Your ACA subsidy (Premium Tax Credit) is based on your Modified Adjusted Gross Income (MAGI), household size, age, and state. The subsidy equals the difference between the benchmark premium (Silver plan) and your maximum premium payment (based on income percentage). Use our calculator by entering your income, household size, age, and state to see your estimated subsidy.
What income qualifies for ACA subsidy?
For 2026 coverage, premium tax credits are available if your income is between 100% and 400% of the Federal Poverty Level (FPL), using the 2025 guidelines: roughly $15,650-$62,600 for a single person and $32,150-$128,600 for a family of 4. Below 100% FPL you may qualify for Medicaid in expansion states. Because the enhanced subsidies expired after 2025, income above 400% FPL gets no credit for 2026 unless Congress changes the law.
What is Modified Adjusted Gross Income (MAGI)?
MAGI is your Adjusted Gross Income (AGI) plus tax-exempt interest, foreign earned income, and certain deductions. For most people, MAGI is close to their AGI. Include wages, self-employment income, interest, dividends, and other taxable income. Use our Freelance Hub to calculate your net income for MAGI estimation.
Am I eligible for Medicaid or ACA subsidy?
In Medicaid expansion states (most states), you're eligible for Medicaid if income is up to 138% of FPL. Above 138% FPL, you qualify for ACA subsidies. In non-expansion states, Medicaid eligibility is very limited (often only for parents/caretakers at ~41% FPL), creating a 'coverage gap' for adults without children. Our calculator shows your eligibility based on your state.
How much will I pay for health insurance with ACA subsidy?
For 2026, the expected contribution toward the benchmark Silver plan is 2.10% of income below 133% FPL, 3.14-4.19% at 133-150%, 4.19-6.60% at 150-200%, 6.60-8.44% at 200-250%, 8.44-9.96% at 250-300%, and 9.96% at 300-400%. Above 400% FPL there is no credit, so you pay the full premium. The calculator estimates your monthly cost from these percentages.
What is the coverage gap?
The coverage gap exists in non-Medicaid expansion states (like Texas, Florida, Georgia) for adults without children. If your income is below 100% FPL, you don't qualify for Medicaid (unless you're a parent/caretaker) or ACA subsidies (which start at 100% FPL). This leaves you without affordable coverage options. Our calculator shows if you're in the coverage gap.
Do I qualify for Cost-Sharing Reductions (CSR)?
Cost-Sharing Reductions (CSR) are available if your income is 100-250% of FPL and you choose a Silver plan. CSR reduces deductibles, copays, and out-of-pocket maximums. At 100-150% FPL, you get 'Platinum-level' benefits. At 150-200% FPL, you get 'Gold-level' benefits. At 200-250% FPL, you get 'Silver-level' benefits. Our calculator shows your CSR eligibility.
How does age affect my ACA premium?
Older individuals pay higher premiums (up to 3x more than younger people). However, subsidies also increase with age because they're based on the benchmark premium. So while your premium is higher, your subsidy is also larger, keeping your out-of-pocket cost based on income percentage. Our calculator accounts for age adjustments.
