How to calculate insurance company’s loss ratio
In the insurance industry, the loss ratio is one of the important indicators to measure the operating status of an insurance company. It reflects the proportion of insurance premium income used for compensation and is directly related to the company's profitability and risk management level. This article will introduce the calculation method of the loss ratio in detail, and combine it with the hot topics and hot content on the entire network in the past 10 days to help readers better understand this concept.
1. Definition of loss ratio

The loss ratio refers to the ratio of the total claims paid by an insurance company in a certain period to the premium income during the same period. It is a key indicator for evaluating the underwriting quality and risk management capabilities of insurance companies. A loss ratio that is too high may mean that the underwriting risk is greater or the pricing is inappropriate, while a loss ratio that is too low may indicate that the company is too conservative and fails to adequately meet customer needs.
2. Calculation formula of loss ratio
The formula for calculating the loss ratio is as follows:
| loss ratio | Calculation formula |
|---|---|
| simple loss ratio | (Compensation expenses ÷ Premium income) × 100% |
| Comprehensive loss ratio | (Compensation expenses + Claims expenses) ÷ Premium income × 100% |
Among them, the simple loss ratio only considers compensation expenses, while the comprehensive loss ratio adds claims expenses and can more fully reflect the actual compensation situation of the insurance company.
3. Factors affecting the loss ratio
The loss ratio is affected by many factors, including the following:
| Influencing factors | Description |
|---|---|
| underwriting risk | High-risk businesses (such as auto insurance, health insurance) usually have higher loss ratios. |
| Pricing strategy | Underpricing premiums can lead to higher loss ratios. |
