What Is the ACA?

The Affordable Care Act (ACA), also known as Obamacare, was designed to make health insurance more affordable and accessible in the United States.

Through the ACA marketplace, eligible individuals can receive:

Premium Tax Credits (subsidies)
Cost-sharing reductions
Medicaid (in expansion states)

Your eligibility depends primarily on:

Household income
Household size
State of residence
Federal Poverty Level (FPL) percentage

This is where our ACA Calculator becomes useful.

What Is the Federal Poverty Level (FPL)?

The Federal Poverty Level (FPL) is a government measure used to determine eligibility for various programs, including ACA subsidies and Medicaid.

FPL changes depending on:

Household size
Yearly federal guidelines

Your FPL percentage is calculated as:

FPL % = (Household Income ÷ FPL Amount for Household Size) × 100

This percentage determines whether you qualify for Medicaid or premium tax credits.

The tool analyzes your financial and household information to determine subsidy eligibility.

It calculates:

1️⃣ FPL Percentage

Understanding Eligibility Categories

🟢 Eligible for Medicaid (Expansion States)

If you live in a Medicaid expansion state and your income is below 138% of FPL, you may qualify for Medicaid.

In this case:

Monthly premium may be $0
No premium tax credit is applied

🟡 Eligible for Premium Tax Credit

If your income is between 100% and 400% of FPL, you may qualify for ACA subsidies.

The calculator estimates your expected income contribution based on FPL range:

100–150% FPL → ~2% contribution
150–200% FPL → ~4%
200–250% FPL → ~6%
250–300% FPL → ~8%
300–400% FPL → ~9.5%

Your subsidy equals:

Premium Cost – Expected Monthly Contribution

🔴 Below 100% FPL (Non-Expansion States)

If income is below 100% FPL in a non-expansion state, subsidy options may be limited.

⚫ Not Eligible for Subsidies

If income exceeds 400% FPL, you may not qualify for premium tax credits.

Example ACA Calculation

Let’s walk through a sample scenario:

Household Income: $45,000
Household Size: 3
State: Expansion
Monthly Premium: $600

Step 1: Determine FPL

For a household of 3, approximate FPL = $24,860

FPL % = ($45,000 ÷ $24,860) × 100 ≈ 181%

Step 2: Determine Contribution Level

At 181% FPL, estimated contribution ≈ 4%

Expected annual contribution:
$45,000 × 0.04 = $1,800

Monthly contribution:
$1,800 ÷ 12 = $150

Step 3: Calculate Tax Credit

Premium: $600
Expected contribution: $150

Tax Credit = $450 per month

Step 4: Final Premium

$600 – $450 = $150 per month

Step 5: Annual Savings

$450 × 12 = $5,400 saved annually

This example shows how significantly ACA subsidies can reduce healthcare costs.
