This Health Insurance Marketplace Calculator 2025 helps you estimate your health insurance costs based on your income, household size, and location. The calculator uses the 2025 federal poverty level (FPL) and premium tax credits to provide an accurate estimate of your potential subsidy.
How to Use This Calculator
To get an accurate estimate of your 2025 health insurance costs:
- Enter your total household income for 2024
- Select your household size
- Choose your state of residence
- Click "Calculate" to see your estimated premium and subsidy
The calculator will show you your estimated monthly premium, the subsidy you may qualify for, and your final monthly cost after the subsidy is applied.
Formula Used
The calculator uses the following formula to estimate your premium and subsidy:
Premium Estimate: Based on average marketplace premiums for your income level and household size
Subsidy Calculation: If your income is below 400% of the federal poverty level (FPL), you may qualify for a premium tax credit (PTC)
Final Cost: Premium - Subsidy
The federal poverty level (FPL) for 2025 is used as the income benchmark. The subsidy amount is calculated based on the percentage of your income above the FPL.
Worked Example
Let's look at an example for a single person in California with an annual income of $35,000:
- Federal Poverty Level (FPL) for 2025: $14,580 for a single person
- 400% of FPL: $58,320
- Income is below 400% FPL, so the person qualifies for a subsidy
- Average marketplace premium for this income level: $350/month
- Subsidy amount: Calculated based on income percentage above FPL
- Final monthly cost: $350 - subsidy amount
Using the calculator with these inputs would show the exact subsidy amount and final cost.
