Understanding Premium Credit‑Schedule Ratings in Workers' Compensation

What a Premium Credit‑Schedule Rating Is

A premium credit‑schedule rating is a classification system insurers use to adjust workers' compensation premiums based on an employer's credit history and loss experience. The rating combines a credit score component with a schedule of experience modifiers to produce a final premium factor.

How the Rating Is Calculated

Insurers first assign a credit score range (e.g., 500‑600, 601‑700) that corresponds to a credit multiplier. Separately, they calculate an experience modification factor (EMF) from the employer's past claim frequency and severity. The premium credit‑schedule rating multiplies the base premium by both the credit multiplier and the EMF.

Why Credit Matters

Credit data reflects financial stability and risk management practices. Companies with stronger credit are viewed as less likely to experience costly claims, so they receive a lower credit multiplier, reducing the overall premium.

Impact of the Experience Modification Factor

The EMF rewards workplaces with fewer or less severe claims and penalizes those with higher loss histories. An EMF below 1.0 lowers the premium, while an EMF above 1.0 raises it.

Strategic Implications for Employers

Improving credit scores and maintaining low claim rates directly lowers the premium credit‑schedule rating, resulting in cost savings. Employers can focus on financial health, safety programs, and proactive claim management to achieve better ratings.
