Severity (Insurance)

Severity in insurance refers to the average cost or dollar amount of each insurance claim when a covered loss occurs. It measures how expensive individual claims are, as opposed to how frequently claims happen, and is a key factor insurance companies use to calculate premiums and assess risk.

Example

“While teenage drivers have high claim frequency, luxury car owners often have high claim severity due to expensive repair costs, even though they may file claims less often.”

Memory Tip

Remember 'SEVERE cost' - severity measures how severe (expensive) each individual claim is when it happens.

Why It Matters

Understanding severity helps explain why insurance premiums vary dramatically between different types of coverage and risk profiles. High-severity risks often require higher premiums even if claims are infrequent, directly impacting what individuals pay for insurance coverage.

Common Misconception

People often confuse severity with frequency, thinking that more claims automatically means higher severity. However, you could have many small, inexpensive claims (high frequency, low severity) or few but very expensive claims (low frequency, high severity), and insurance companies price these scenarios very differently.

In Practice

An auto insurer analyzes their data and finds that sports car owners file claims only 8% of the time annually (low frequency) but average $15,000 per claim due to expensive parts and repairs (high severity). In contrast, economy car owners file claims 12% of the time (higher frequency) but average only $4,500 per claim (lower severity). Despite fewer claims, sports car owners pay higher premiums due to the high severity risk.

Etymology

Derived from Latin 'severitas' meaning 'strictness' or 'harshness,' the term entered insurance vocabulary in the early 20th century to describe the harsh financial impact of individual claims.
