Level-funded plans are a middle ground between traditional insurance and self-funding. You pay a predictable monthly amount, but if your employees use less health care than expected, you can get money back. It is like traditional insurance with a built-in refund possibility for healthy groups.
This tool compares a level-funded plan against your current fully insured setup. Enter your company details below and you will see whether the potential savings and refund opportunity make this a good fit for your team. It works best for companies with 10-100 employees and relatively healthy workforces.

| Component | PEPM | Monthly Total | % of Total |
|---|
Fully Insured Cost:
Current PEPM x number of employees x 12 months. Projected forward using the annual renewal increase rate.
Level-Funded Breakdown:
- Claims Fund: PEPM x claims ratio x state cost index x age factor x industry adjustment. This is held in a claims account to pay medical expenses.
- Admin Fee: PEPM x admin percentage. Covers TPA fees, network access, compliance, and reporting.
- Stop-Loss Premium: Based on attachment point selected. Lower attachment = higher premium but more protection. Rates from Sun Life/Voya reference schedules adjusted for group demographics.
- Total Level-Funded: Claims Fund + Admin Fee + Stop-Loss Premium.
Scenario Modeling:
- Best Case: Actual claims at 55% of expected. Employer receives ~50% of surplus (unused claims fund) as a refund.
- Expected Case: Actual claims match the expected claims fund. No surplus, no shortfall — typical 5-15% savings vs fully insured.
- Worst Case: Claims run 130% of expected, but stop-loss (both specific and aggregate) caps total exposure. Maximum cost is capped at claims fund + stop-loss corridor (typically 125% of expected).
State Cost Index:
Adjusts base claims for state-level provider costs, utilization patterns, and regulatory environment. Based on CMS Geographic Practice Cost Index and state premium filings.
Age Factor:
Uses CMS 3:1 age rating curve. Age 21 = 1.0, age 40 = 1.278, age 64 = 3.0. Normalized to the baseline age of 38.
3-Year Projection:
Fully insured trends at the entered renewal rate. Level-funded trends at 75% of the fully insured rate because claims experience has more direct impact on renewals.
