EMR — Experience Modification Rate Explained | Glossary

EMR (Experience Modification Rate)

An insurance industry metric comparing a company's workers' compensation claims experience to the average for businesses of similar size and industry.

Key Facts

An EMR of 1.0 = average claims experience for your industry
Below 1.0 = better than average (lower premiums)
Based on 3-year claims history compared to industry/size peers
Directly multiplies workers’ comp premium (1.25 EMR = 25% higher)

EMR (also called Experience Mod, E-Mod, or X-Mod) is calculated by rating bureaus (like NCCI) using the employer's 3-year claims history compared to the expected loss rate for their industry and size class. An EMR of 1.0 represents average performance. Below 1.0 means fewer/less severe claims than average (lower premiums); above 1.0 means more (higher premiums). EMR directly multiplies the base workers' comp premium — a 1.25 EMR means 25% higher premiums. Many construction and industrial clients require contractors to maintain EMR below 1.0 or a specific threshold.

Type	Formula Basis	What It Measures	Used By	Good Benchmark
TRIR	(Incidents × 200K) ÷ Hours	All recordable incidents	OSHA, clients	< 3.0 (construction)
DART	(DART cases × 200K) ÷ Hours	Severe cases (days away/restricted)	Insurance, clients	Below industry avg
EMR	3-yr claims vs expected	Claims experience vs average	Insurance carriers	< 1.0
CSA Score	Inspection/crash/violation data	Carrier safety across 7 BASICs	FMCSA	Below intervention threshold
