Calculation Methodology

Base Premium Calculation: We start with the KFF 2025 national average single premium ($720/mo) and apply the South Dakota cost index (0.92) 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.
