Kaiser Family Foundation Health Insurance Marketplace Calculator

Reviewed by Calculator Editorial Team

The Kaiser Family Foundation Health Insurance Marketplace Calculator helps you estimate health insurance costs based on your income, household size, and location. This tool provides estimates for premiums, subsidies, and out-of-pocket costs to help you understand your options under the Affordable Care Act.

How to Use This Calculator

To get accurate estimates, follow these steps:

  1. Enter your total household income in the "Annual Household Income" field.
  2. Select the number of people in your household from the dropdown menu.
  3. Choose your state of residence from the list.
  4. Click "Calculate" to see your estimated premiums and subsidies.

Note: These calculations are estimates based on 2023 federal guidelines. Actual costs may vary based on specific plan details and enrollment periods.

Formula Used

The calculator uses the following formula to estimate premium subsidies:

Premium Subsidy = (Federal Poverty Level × 4) - Annual Household Income

If Premium Subsidy > 0, then Subsidy Amount = Premium Subsidy × 0.095 (9.5% of the subsidy)

Otherwise, Subsidy Amount = 0

The Federal Poverty Level (FPL) is adjusted annually by the U.S. Department of Health and Human Services. The calculator uses the 2023 FPL values for all calculations.

Worked Example

Let's calculate premium subsidies for a household with $40,000 annual income and 2 people in California:

  1. Federal Poverty Level for 2 people in California: $27,360
  2. Calculate potential subsidy: (27,360 × 4) - 40,000 = $70,240 - $40,000 = $30,240
  3. Apply 9.5% subsidy rate: $30,240 × 0.095 = $2,871.80

This household would qualify for approximately $2,871.80 in premium subsidies.

Income Level Subsidy Amount Notes
$30,000 $0 Income exceeds 400% FPL
$25,000 $1,512 Income between 133% and 400% FPL
$15,000 $2,872 Income below 133% FPL

Interpreting Results

The calculator provides three key pieces of information:

  • Estimated Premium: The monthly cost of your health insurance plan before subsidies.
  • Subsidy Amount: The federal government's contribution to reduce your premium cost.
  • Out-of-Pocket Maximum: The most you'll pay for covered services in a year.

Remember that these are estimates. Actual costs depend on:

  • Your specific health plan
  • Enrollment period (Open Enrollment vs. Special Enrollment)
  • State-specific regulations
  • Changes in federal poverty levels
