Calculation Methodology

Base Premium Calculation: We start with the KFF 2025 national average single premium ($720/mo) and apply the Idaho cost index (0.88) to get the state-adjusted base rate. Age adjustments use the CMS 3:1 federal age curve, and tier mix multipliers convert single rates to blended PEPM costs.

Funding Type Adjustments: Fully insured rates include carrier margin (15-20%) and risk charges. Level-funded rates remove 8-12% of carrier margin but add stop-loss premium. Self-funded rates are pure expected claims plus admin fees (typically $30-50 PEPM) and stop-loss. PEO rates reflect group purchasing power (typically 15% below direct market). MEWA rates are similar to PEO but with association-specific pool dynamics.

Trend Projections: 3-year projections use funding-type-specific trend rates: fully insured (7.8%), level-funded (5.0%), self-funded (4.7%), PEO (3.7%).

Limitations: This calculator provides estimates based on market averages. Actual premiums depend on your specific group's claims history, plan design, carrier underwriting, and negotiated rates. Use this as a comparison starting point, then request actual quotes.

What Idaho Employers Need to Know About Health Insurance Costs

Idaho offers relatively affordable health insurance with a cost index of 0.88, about 12% below the national average. The state has a growing but still limited carrier market, with Blue Cross of Idaho as the dominant player supplemented by SelectHealth and regional CO-OPs.

Idaho operates its own state-based marketplace, Your Health Idaho, and expanded Medicaid via ballot initiative in 2018. The Medicaid expansion has helped reduce the uninsured rate and stabilize the small-group market.

Idaho's rapidly growing population, particularly in the Boise metro area, is attracting new carrier entrants and increasing competition. However, rural areas of the state continue to face limited provider networks and fewer plan options.

The state's business-friendly regulatory environment makes PEO arrangements and association health plans attractive options for small employers. Level-funded plans are gaining popularity among Idaho employers with 20-75 employees who want potential savings without full self-funding risk.

Idaho Continuation Coverage: State continuation: None specific beyond federal COBRA. Federal COBRA applies to employers with 20+ employees.
