“Is it expensive?” might be the first question most business owners have about workers compensation insurance. The answer varies greatly from state to state (since each state has different workers compensation laws) and the insurance company from which you purchase your policy.
Generally, there are five factors that will determine your workers compensation premiums:
- How many employees you have
- Your company’s claims history
- Experience Modification Rates
- The type of work they do
- Workers Compensation Class Codes
The formula that the insurers use to calculate your workers comp rate can be simplified as:
Employee Classification Rate X Employer Payroll (Per $100) X Experience Mod Rate = Your Workers Comp Premium
The biggest single driver of workers compensation premium fluctuations is the Experience Modification Rates, also known as XMods. The XMod is a mathematical formula that insurance carriers use to compare similar businesses.
An insurer compares a company’s estimated losses to actual ones over a three-year period, then assigns a number rating, with the hypothetical “average” being 1.00.
If a company has more losses than average, the score climbs above 1.00, thereby “taxing” the business for past claims. If a company outperforms its peers in safety, with fewer claims, the score drops below 1.00 and counts as a “credit.”
The Inspection Bureau, which promulgates experience modifications, does occasionally make mistakes. It’s advisable to review the worksheet yearly to confirm accuracy. This is yet another reason why working with an experienced and knowledgeable broker who’s committed to protecting your business from excessive costs is highly recommended.
