Health Insurance Subsidy Calculator

Health insurance subsidies help make coverage more affordable for eligible individuals and families. This calculator helps you estimate your potential subsidy based on your income, household size, and filing status.

How the Health Insurance Subsidy Works

The Affordable Care Act (ACA) provides subsidies to help lower-income individuals and families pay for health insurance through the Marketplace. The amount of your subsidy depends on several factors:

Your income
Your household size
Your filing status (single, married filing jointly, etc.)
The cost of the second-lowest silver plan in your area

The subsidy is calculated as a percentage of the second-lowest silver plan cost. The percentage is determined by your income relative to the federal poverty level.

Note: The actual subsidy amount may vary slightly from this estimate because the official calculation uses more precise income thresholds and plan costs specific to your location.

How to Calculate Your Subsidy

To estimate your health insurance subsidy, you'll need to know:

Your total household income for the year
The number of people in your household
Your filing status

The subsidy is calculated using the following formula:

Subsidy Percentage = (Income Threshold - Your Income) / Income Threshold

Subsidy Amount = Subsidy Percentage × Second-Lowest Silver Plan Cost

The income thresholds are based on the federal poverty level, adjusted for household size. For example, in 2023, the federal poverty level for a single person was $13,590, and for a family of four it was $28,220.

Worked Example

Let's say you have a household income of $30,000, you live in a family of four, and your filing status is married filing jointly. The second-lowest silver plan in your area costs $500 per month.

First, find the income threshold for a family of four: $28,220.

Then calculate the subsidy percentage:

(28,220 - 30,000) / 28,220 = -0.0634 or 6.34%

Since the result is negative, you don't qualify for a subsidy in this case. If your income were $25,000, the calculation would be:

(28,220 - 25,000) / 28,220 = 0.1138 or 11.38%

Then the subsidy amount would be:

0.1138 × $500 = $56.90 per month
