Understanding How Your Workers’ Compensation Rate is Calculated

For staffing firms, workers’ compensation is one of the most significant insurance costs. At PEC, we believe that knowing how your rate is calculated is the first step toward managing it effectively and protecting your business.

Classification Codes and Payroll

Every employee is assigned a classification code that reflects the nature of their work. In staffing, this means correctly identifying the duties performed by each placed worker across different job sites and industries. These codes carry individual base rates set by the Pennsylvania Compensation Rating Bureau.

Your premium is calculated by multiplying the carrier’s classification rate by your payroll in that class, per $100. Accurate classifications and payroll reporting are essential to avoid overpaying or facing unexpected audits.

The Experience Modification Factor

Your experience modification factor, or mod, is based on your company’s historical loss experience compared to others of similar size and industry. A mod of 1.00 means your actual loss experience matches up with expected loss experience for companies of similar size and classification.. If your firm has fewer and less severe claims, your mod may be lower than 1.00, reducing your premium. A higher mod typically results in higher premiums.

Because staffing firms often have diverse placements and complex claim exposures, actively managing your mod can lead to substantial cost savings.
