The combined ratio represents total insurance costs (losses incurred plus expenses) compared to revenue from premiums: A ratio below 100 indicates an underwriting profit, and one above 100 indicates a loss. When the investment income that an insurer earns from holding policyholders’ funds (“the float”) is taken into account, a combined ratio in the 107-111 range typically produces an overall breakeven result, exclusive of earnings on the funds provided by shareholders.
