loss ratio

An insurance metric comparing claims paid to premiums collected, expressed as a percentage. A loss ratio below 100% means the insurer is profitable on underwriting.

Example

A health insurer with a 90% loss ratio paid out $90 in claims for every $100 in premiums collected.

Memory Tip

LOSS RATIO = claims divided by premiums. Below 100% = profitable underwriting.

Why It Matters

Understanding loss ratio helps you evaluate insurance company financial health and stability. When choosing an insurance provider, a company with consistently low loss ratios demonstrates strong profitability and is more likely to pay claims reliably without raising premiums or going out of business.

Common Misconception

Many people mistakenly believe a low loss ratio is bad for customers because it means the insurer is keeping more money. In reality, a healthy loss ratio below 100% indicates the company is financially stable and can continue serving customers responsibly without insolvency risk.

In Practice

Suppose an auto insurance company collects 10 million dollars in premiums in a year and pays out 7 million dollars in claims. Their loss ratio would be 70 percent, meaning they keep 30 percent to cover operating expenses and profit. A different insurer collecting 10 million but paying out 11 million would have a 110 percent loss ratio, indicating they are unprofitable and operating at a loss.

Etymology

LOSS (claims paid out) RATIO (proportion to premiums). The proportion of premiums spent on LOSSES.
