Loss Development Factor

Updated: 16 November 2024

What Does Loss Development Factor Mean?

Loss development factors are variables used to calculate the total amount of money insurance companies will need to pay in claims for a given period. These factors are necessary because claims are often reported after the “loss development” period has ended. As a result, the actual claims to be paid are likely significantly higher than the claims reported at the close of a loss development period, such as a year.

Insuranceopedia Explains Loss Development Factor

To understand how loss development factors work, consider a company with a loss development factor of 1.4. This means that for every $1 reported during a loss development period, $1.40 will ultimately need to be paid out due to additional claims being reported later. For example, if the insurer’s loss development factor is 1.4 and it experiences $100,000 in current claims, applying the factor indicates that the company will likely need to pay $140,000 in total claims ($100,000 × 1.4).
