Formula Used
The Kaiser Health Insurance Marketplace Calculator uses the following formula to estimate monthly premiums:
Premium Estimation Formula
Monthly Premium = (Base Premium × Income Factor × Age Factor × Location Factor) - Subsidy Amount
Where:
- Base Premium = Standard rate for selected coverage level
- Income Factor = Adjustment based on household income
- Age Factor = Adjustment based on applicant's age
- Location Factor = Adjustment based on state and county rates
- Subsidy Amount = Calculated based on income and household size
The calculator uses current 2024 rates from the Kaiser Family Foundation and HealthCare.gov data. For exact premiums, you should apply directly through the marketplace.
Worked Example
Let's calculate premiums for a 35-year-old single applicant in California with an income of $45,000 and Silver coverage level.
- Base Silver premium in California: $450/month
- Income factor (400% of federal poverty level): 1.2
- Age factor (35 years): 1.0
- Location factor (California): 1.1
- Subsidy amount: $200/month (qualifies for partial subsidy)
Calculation: (450 × 1.2 × 1.0 × 1.1) - 200 = $594 - $200 = $394/month
Example Result
Estimated monthly premium: $394
Subsidy amount: $200
Out-of-pocket maximum: $7,050
Eligibility status: Eligible for partial subsidy
