The KFF Health Insurance Marketplace Calculator 2026 helps you estimate your potential health insurance premiums for the 2026 open enrollment period. This tool uses the latest KFF projections and federal guidelines to provide a realistic estimate based on your income, household size, and location.
How to Use This Calculator
Using this calculator is simple:
- Enter your total household income for 2025
- Select your household size
- Choose your state of residence
- Click "Calculate" to see your estimated premium
The calculator will display your estimated monthly premium based on the federal poverty level (FPL) and the 2026 subsidy rules. Keep in mind this is an estimate and your actual premium may vary based on your specific circumstances.
Formula Used
The calculator uses the following formula to estimate your premium:
Estimated Premium = (FPL Percentage × Base Premium) - Subsidy Amount
Where:
- FPL Percentage = Your household income divided by the 2026 federal poverty level
- Base Premium = Average premium for your state and household size
- Subsidy Amount = Government subsidy based on your income

Key Features of the Marketplace
- Subsidies based on income and household size
- Standardized plans with essential health benefits
- Open enrollment period each year
- State-specific options and regulations
Important Note
This calculator provides estimates only. Your actual premium may differ based on factors not included in this calculation, such as your specific health status, age, and the plans you select.
Example Calculation
Let's look at an example for a household with:
- Total income: $45,000
- Household size: 3
- State: California
Based on the 2026 federal poverty level of $30,000 for a family of 3, this household would qualify for a subsidy. The calculator would estimate a monthly premium of approximately $125 after applying the subsidy.

|---|---|---|
