Wisconsin Level-Funded Market at a Glance
Level-Funded Health Insurance in Wisconsin: What Employers Need to Know
Wisconsin has a competitive health insurance market with a good mix of regional and national carriers. The state's cost index of 1.00 is at the national average, with significant variation between the Milwaukee metro area and more rural regions. Level-funded plans are well-established in Wisconsin, with strong adoption among mid-size employers in manufacturing, agriculture, and professional services.
The Wisconsin market features both national carriers (UnitedHealthcare, Cigna, Aetna, Anthem) and regional carriers (Quartz, Dean Health, Group Health Cooperative) in the fully insured space. Level-funded products are offered by the national carriers, and some regional carriers have begun developing level-funded alternatives as well. The Milwaukee, Madison, and Green Bay metro areas have the most competitive carrier landscapes.
Wisconsin's Office of the Commissioner of Insurance treats level-funded plans as self-funded under ERISA and has maintained a stable regulatory environment. The state has moderate benefit mandates, including mental health parity and chiropractic coverage requirements. Wisconsin's manufacturing-heavy economy means many employers are familiar with self-funded concepts through larger competitors, reducing the educational barrier to level-funded adoption.

Calculation Methodology
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 (1.0 for Wisconsin) x age factor x industry adjustment x plan tier multiplier. 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. Adjusted by Wisconsin's stop-loss factor (1.0) and 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. Typical savings vs fully insured.
- Worst Case: Claims run 130% of expected, but stop-loss caps total exposure at 125% of expected claims fund.
State Cost Index: Wisconsin's index of 1.0 adjusts base claims for state-level provider costs, utilization patterns, and regulatory environment. Based on CMS Geographic Practice Cost Index and Wisconsin DOI rate filings.
Data Sources: SOA Group Health Experience Study, Mercer National Survey 2025, KFF 2025 Employer Health Benefits Survey, TrustMark/Voya level-funded reference data, Sun Life stop-loss rate manuals, NAIC stop-loss model regulations, CMS Federal Age Rating Curves, Wisconsin Department of Insurance filings.
Analyst Notes: Wisconsin Level-Funded Market
Actuarial Context: Wisconsin's cost index of 1.0 reflects the state's position relative to the national average for employer-sponsored health insurance. The level-funded discount potential of 12% is achievable for groups with favorable demographics, but actuarial credibility requires sufficient enrollment -- typically 2+ employees for most carriers in Wisconsin. Groups below this threshold face wider confidence intervals in claims projections, which carriers compensate for through higher stop-loss premiums and reduced surplus return percentages.
Methodology Disclosure: This calculator uses a simplified actuarial model that applies age factors (CMS 3:1 curve), industry adjustments (SOA experience studies), and state-specific cost indices (CMS GPCI) to the user's inputs. The stop-loss pricing is based on reference rate schedules from major reinsurers, adjusted by Wisconsin's stop-loss factor of 1.0. Actual carrier quotes will incorporate additional underwriting factors including census-level age/gender distribution, prior claims experience, SIC code, plan design details, and network selection.
Risk Assessment: The very competitive carrier market in Wisconsin provides strong competitive dynamics for level-funded pricing. Strong carrier competition provides good renewal leverage. Employers should request quotes from at least 3-4 carriers to ensure competitive terms on admin fees, stop-loss pricing, and surplus return provisions.
