How the KFF Subsidy Calculator Works

The calculator uses Affordable Care Act subsidy guidelines and household information to estimate assistance.

Examples include:

• Employment income
• Self-employment income
• Retirement income
• Investment income
• Other taxable income

State of Residence

---

Calculation Logic

The calculator estimates the expected contribution a household must make toward benchmark health insurance premiums.

Basic Formula

Estimated Subsidy:

Subsidy = Benchmark Premium − Expected Household Contribution

Where:

• Benchmark Premium = Cost of the benchmark Marketplace plan
• Expected Contribution = Percentage of household income based on ACA guidelines

If the benchmark premium exceeds the expected contribution, the difference becomes the estimated subsidy amount.

Example Calculation

Consider the following scenario:

Household Information

• Family Size: 4
• Annual Income: $60,000
• State: Texas
• Ages: 35, 34, 8, and 5

Estimated Results

• Benchmark Annual Premium: $12,000
• Expected Household Contribution: $4,500
• Estimated Subsidy: $7,500

Monthly subsidy:

$7,500 ÷ 12 = $625

The family may receive approximately $625 per month toward health insurance premiums.
