How is the Experience Modification Rate (EMR) calculated?

The Experience Modification Rate (EMR) is calculated using the formula that compares an employer's actual losses to their expected losses over a specific period of time. This rate serves as a measure of an employer's safety record and is used in determining workers' compensation insurance premiums.

When using the formula of actual losses over expected losses, a lower EMR indicates a safer workplace with fewer incidents, and therefore, an employer is likely to pay lower premiums. Conversely, a higher EMR signals a history of more frequent or severe workplace injuries, leading to higher insurance costs.

This calculation helps to promote safety within the construction industry by incentivizing employers to maintain safe work environments in order to lower their insurance rates. Understanding the EMR is crucial for both safety management and financial planning in construction projects.
