About This Tool
Disclaimer Indicative profitability analysis only. The Combined Ratio excludes investment income; the Operating Ratio adjustment is illustrative. Benchmarks are industry medians: an individual company's results may differ materially based on mix of business and geographic concentration. Not a substitute for actuarial sign-off or statutory filing.
Loss Ratio (Incurred Losses + LAE) ÷ Earned Premium. Measures the share of premium consumed by claims and claims-handling cost. P&C underwriting fundamentals
Expense Ratio Underwriting Expenses ÷ Written or Earned Premium. Measures the cost of acquiring and servicing the book. Statutory accounting (Written basis)
Combined Ratio Loss Ratio + Expense Ratio. Below 100% indicates an underwriting profit; above 100% an underwriting loss before investment income. Universal P&C KPI
NAIC IRIS Ratios The NAIC Insurance Regulatory Information System screens insurer financial health; a two-year combined ratio above its usual range can flag a solvency concern for regulatory review. NAIC IRIS Ratios Manual (2025)
