Professional Liability vs General Liability Cost Comparator

Compare estimated annual premiums for Professional Liability (Errors & Omissions) and General Liability insurance based on your business profile, revenue, and coverage limits.

Formulas Used

Professional Liability (E&O) Annual Premium:

PL_Base     = Revenue × Industry_PL_Rate (% of revenue, industry-specific)
PL_Base     = clamp(PL_Base, Industry_Floor, Industry_Ceiling)
PL_Premium  = PL_Base × Limit_Factor × Deductible_Factor
                       × Claims_Factor × Location_Factor × Employee_Factor

General Liability (CGL) Annual Premium:

GL_Base     = (Revenue ÷ 1,000) × Industry_GL_Rate ($ per $1,000 revenue)
GL_Base     = clamp(GL_Base, Industry_Floor, Industry_Ceiling)
GL_Premium  = GL_Base × Limit_Factor × Deductible_Factor
                       × Claims_Factor × Location_Factor × Employee_Factor

Combined Bundle Premium:

Combined    = (PL_Premium + GL_Premium) × (1 − 0.08)   [8% bundle discount]

Key Rating Factors:

  • Limit Factor: Relativities vs. $1M baseline (ISO-based): 0.65× ($250K) → 1.90× ($5M) for PL; 0.72× ($300K) → 1.28× ($2M) for GL
  • Deductible Credit: Higher deductibles reduce premium: $0 = 1.00×, $25K = 0.70× (PL); $0 = 1.00×, $5K = 0.83× (GL)
  • Claims Surcharge: 0 claims = 1.00×; 1 = 1.20× (PL) / 1.15× (GL); 3+ = 1.75× (PL) / 1.60× (GL)
  • Location Factor: Low-risk states = 0.88–0.90×; High-risk states (CA, NY, FL, TX) = 1.18–1.22×
  • Employee Factor: 1–5 employees = 1.00×; 100+ employees = 1.60–1.75×
