Reviewed by Calculator Editorial Team

Determining your health care subsidy in 2018 involves calculating your premium tax credit based on your income and family size. This guide explains the process, provides a calculator, and answers common questions about the 2018 health care subsidy program.

How to Calculate Health Care Subsidy 2018

The 2018 health care subsidy was part of the Affordable Care Act (ACA) and provided financial assistance to help individuals and families pay for health insurance premiums. The subsidy amount was based on your income, family size, and the cost of the second-lowest silver plan in your area.

Key Requirements

  • You must be a U.S. resident
  • You must not be eligible for other health coverage through an employer or government program
  • You must purchase health insurance through the Health Insurance Marketplace
  • Your income must be within certain limits (below 400% of the federal poverty level)

Calculation Process

The subsidy calculation involves several steps:

  1. Determine your income and family size
  2. Find the cost of the second-lowest silver plan in your area
  3. Calculate your premium tax credit using the formula
  4. Apply the credit to your health insurance premium

Note: The 2018 health care subsidy program was part of the ACA and was available through the Health Insurance Marketplace. The exact subsidy amount varied by location and individual circumstances.

Formula and Calculation Steps

The premium tax credit for 2018 was calculated using the following formula:

Premium Tax Credit = (Monthly Premium × 0.095) - (0.01 × (Income - (3 × Federal Poverty Level × Family Size)))

Where:

  • Monthly Premium = Cost of the second-lowest silver plan in your area
  • Income = Your total household income
  • Federal Poverty Level = The official poverty level for your state
  • Family Size = Number of people in your household

Step-by-Step Calculation

  1. Find the cost of the second-lowest silver plan in your area
  2. Calculate 9.5% of the monthly premium
  3. Determine your income adjusted for the federal poverty level
  4. Calculate 1% of the income adjustment
  5. Subtract the income adjustment from the premium percentage
  6. Round the result to the nearest dollar

Important: The actual subsidy amount may vary based on your specific circumstances and location. This calculator provides an estimate based on the general formula.

Worked Example

Let's calculate a subsidy for a family of four with an income of $50,000 and a monthly premium of $300.

Given:

  • Monthly Premium = $300
  • Income = $50,000
  • Federal Poverty Level (for a family of 4) = $24,600
  • Family Size = 4

Calculation:

  1. 9.5% of $300 = $28.50
  2. Income adjustment = $50,000 - (3 × $24,600 × 4) = $50,000 - $295,200 = -$245,200
  3. 1% of income adjustment = -$2,452
  4. Premium Tax Credit = $28.50 - (-$2,452) = $2,480.50
  5. Rounded to $2,481

The estimated premium tax credit for this family would be $2,481 per month.

This is an example only. Actual subsidy amounts may differ based on your specific location and circumstances.
