Combined Ratio
Combined Ratio is the primary profitability metric for general (non-life) insurance companies, calculated as the sum of the claims loss ratio and the expense ratio, with a figure below 100 per cent indicating underwriting profit and above 100 per cent indicating underwriting loss.
Unlike life insurance which is primarily an investment and protection business evaluated through embedded value metrics, general insurance — which covers motor, health, fire, marine, crop, and other short-duration risks — is an underwriting business where the key question is whether premiums collected are sufficient to pay claims and cover operating costs. Combined ratio answers this question directly.
The loss ratio (also called claims ratio) is incurred claims plus adjustment expenses divided by net earned premiums. It measures what percentage of every premium rupee collected is paid out in claims. A loss ratio of 75 per cent means Rs 75 of every Rs 100 collected is paid in claims; Rs 25 remains to cover expenses and profit.
The expense ratio is underwriting expenses (commissions, marketing, and administrative costs) divided by net written premiums. It measures the cost of distributing and managing the insurance operations as a share of premiums. A combined ratio of 100 per cent means claims and expenses together exactly equal premium revenue — no underwriting profit or loss. Below 100 per cent is profitable from underwriting; above 100 per cent means the insurer is paying out more in claims and expenses than it collects in premiums and relies on investment income from the float to remain overall profitable.
In India, general insurers have historically run combined ratios at or above 100 per cent for many business lines, particularly for motor third-party insurance (where tariffs were regulated and inadequate) and for crop insurance under PMFBY (Pradhan Mantri Fasal Bima Yojana), where adverse monsoon seasons triggered sharp loss ratio spikes. ICICI Lombard General Insurance and HDFC ERGO General Insurance were among the private sector players that consistently managed combined ratios more tightly than public sector general insurers.
Investors evaluating Indian general insurance companies must pay attention to the business line mix because combined ratios differ widely across segments. A motor-heavy insurer in a year with high accident frequency will show a very different combined ratio from a health-heavy insurer in a year with benign claims experience. Reading the combined ratio alongside segment breakdowns and reserve development (whether prior year claims estimates were adequate) provides a complete picture of underwriting discipline.
