Key metrics and calculations
The following formulas are used to calculate essential performance indicators:
Loss ratio = (Direct losses incurred ÷ Direct premium earned) × 100
Expense ratio = ((Direct defense & cost containment expense incurred + commissions & brokerage expenses + taxes, licenses & fees) ÷ Direct premium earned) × 100
Combined ratio = Loss ratio + Expense ratio
Defense-to-loss ratio = (Direct defense & cost containment expense paid ÷ Direct losses paid) × 100
