Level-Funded Health Insurance in Arizona: What Employers Need to Know
Arizona offers one of the most favorable environments for level-funded health plans in the country. With a cost index of 0.88 and minimal state-specific mandates beyond ACA requirements, Arizona employers can access level-funded arrangements that are genuinely less expensive than their fully insured equivalents. The state's growing population and expanding employer base have attracted multiple level-funded carriers, creating healthy competition that benefits employers.
The Phoenix and Tucson metro areas have particularly robust level-funded markets, with carriers like UnitedHealthcare, Cigna, Aetna, and newer entrants like Sana Benefits actively competing for business. This competition has driven down admin fees and improved stop-loss terms relative to national averages. Arizona's minimum group size for level-funded plans is just 2 employees with most carriers, making the option available to even the smallest employer groups.
Arizona does not impose significant state-level mandates beyond ACA requirements, which simplifies plan design and reduces compliance costs for level-funded arrangements. The state's relatively young workforce demographics in key industries like technology, construction, and hospitality also favor level-funded plans, as younger groups tend to have more predictable (and lower) claims experience. Surplus return provisions are generous, with most carriers returning 50-80% of unused claims funds.

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 (0.88 for Arizona) 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 Arizona's stop-loss factor (0.95) 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: Arizona's index of 0.88 adjusts base claims for state-level provider costs, utilization patterns, and regulatory environment. Based on CMS Geographic Practice Cost Index and Arizona 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, Arizona Department of Insurance filings.
Analyst Notes: Arizona Level-Funded Market
Actuarial Context: Arizona's cost index of 0.88 reflects the state's position relative to the national average for employer-sponsored health insurance. The level-funded discount potential of 14% is achievable for groups with favorable demographics, but actuarial credibility requires sufficient enrollment -- typically 2+ employees for most carriers in Arizona. 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 Arizona's stop-loss factor of 0.95. 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 Arizona provides strong competitive dynamics for level-funded pricing. Multiple carrier options provide competitive 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.
