An insurance loss ratio, calculated by dividing incurred losses by earned premiums, is a measure of profitability that reflects the extent to which an insurance company’s incurred losses match its earned premiums. A ratio below 100% suggests a profit, while a ratio above 100% indicates a loss.
Calculating insurance loss ratios is necessary for insurance companies to determine their financial performance and set appropriate rates. Furthermore, insurance regulators often use loss ratios to assess the solvency and viability of insurance companies. Understanding how to calculate insurance loss ratios provides valuable insights into an insurer’s financial health and its underwriting effectiveness.
