Which factor is the key determinant in workers' compensation premium rates?

• A. Job Classification
• B. Payroll
• C. Past Experience
• D. Discounts

Answer: (A)

The key determinant in workers' compensation premium rates is the job classification. Each classification code carries a specific rate that reflects the inherent risk of the work performed. A more hazardous classification has a higher rate, while a safer one has a lower rate. The premium is typically calculated by applying that rate to the employer’s payroll (often expressed as rate per $100 of payroll), so the actual amount due depends on both the assigned rate and the payroll amount. Past experience can adjust the final premium through an experience modification factor, which can raise or lower the premium based on the employer’s claims history, but it does not set the base rate itself. Discounts may further reduce the final premium, but they are adjustments, not the determinant of the rate.
