Kaiser ACA Subsidy Calculator
Finding affordable health insurance can feel overwhelming, especially when trying to understand subsidies under the Affordable Care Act (ACA). Premium tax credits, income limits, Federal Poverty Level (FPL) percentages, and plan tiers all impact what you actually pay each month.
Our Kaiser ACA Subsidy Calculator is designed to make this process simple. In just a few steps, you can estimate:
- Your Federal Poverty Level (FPL) percentage
- Estimated monthly premium
- Monthly subsidy (premium tax credit)
- Your actual monthly cost
- Annual subsidy amount
- Annual out-of-pocket premium cost
- Subsidy eligibility status
Whether you’re comparing Bronze vs. Silver plans or checking if your income qualifies for assistance, this tool gives you a fast, clear estimate based on 2024 ACA guidelines.
What Is the ACA Subsidy?
Under the Affordable Care Act, individuals and families who purchase health insurance through the Marketplace may qualify for premium tax credits. These subsidies lower your monthly premium cost based on:
- Household size
- Annual household income
- Age
- State of residence
- Plan type
- Tobacco usage
The lower your income compared to the Federal Poverty Level, the larger your potential subsidy.
How the Kaiser ACA Subsidy Calculator Works
Our tool uses several core inputs to estimate your subsidy:
1. Household Size
Federal Poverty Level thresholds increase with each additional household member. Your household size directly impacts your FPL percentage.
2. Annual Household Income
Your income determines where you fall relative to the Federal Poverty Level. This percentage determines your expected contribution toward health insurance premiums.
3. Age
Insurance premiums increase with age. The calculator adjusts your estimated premium using age-based factors, especially for individuals over 40.
4. State Selection
Marketplace premiums vary by state. The tool includes selectable states such as:
- California
- Colorado
- Georgia
- Hawaii
- Oregon
- Washington
- Virginia
- Maryland
- District of Columbia
5. Plan Type
You can compare estimated costs for:
- Bronze
- Silver
- Gold
- Platinum
Each plan tier offers different premium levels and coverage percentages.
6. Tobacco Usage
Tobacco users may face higher premiums. The calculator adjusts the monthly premium accordingly if “Yes” is selected.

Example Calculation
Let’s walk through a realistic example:
- Household size: 2
- Annual income: $40,000
- Age: 45
- Plan type: Silver
- Tobacco use: No
Step 1: FPL Calculation
For a household of 2, the Federal Poverty Level baseline is used to determine your income percentage.
If your income equals around 200% of FPL, you are generally eligible for subsidies.
Step 2: Premium Adjustment
At age 45, premiums are adjusted upward compared to younger adults.
Step 3: Contribution Percentage
Based on your FPL percentage, your expected premium contribution is capped at a set percentage of income.
Step 4: Subsidy Calculation
The difference between your adjusted premium and your maximum contribution becomes your monthly subsidy.
The tool automatically calculates:
- Monthly tax credit
- Reduced premium
- Total annual savings
This helps you compare plans before enrolling.
