What a South Carolina Workers' Compensation Cost Sheet Shows
A South Carolina workers' compensation cost sheet lists the premium rates an employer must pay to cover employee injuries, broken down by classification, payroll, and experience rating. It tells the insurer how much coverage costs for each job category and how adjustments like safety programs or claim history affect the final bill.

Key Components of the Cost Sheet
Each line on the sheet represents a specific labor classification, such as "Construction Laborer" or "Office Clerk," with the following essential columns:
- Classification Code – The state-assigned numeric code for the job type.
- Payroll – Total wages reported for that classification during the policy period.
- Rate per $100 – The base premium charged for every $100 of payroll.
- Experience Modifier – A factor (often 0.80‑1.20) that raises or lowers the base rate based on the employer's claim history.
- Premium – Calculated as Payroll ÷ 100 × Rate × Modifier.
How Rates Are Determined in South Carolina
The South Carolina Workers' Compensation Commission sets the base rates each year, reflecting statewide injury trends and medical cost inflation. Insurers then apply the employer's experience modifier, which rewards low claim frequencies and penalizes high loss ratios. Additional surcharges may appear for high‑risk industries or if the employer opts out of state-sponsored safety programs.
Reading the Total Cost Section
At the bottom of the sheet, the insurer aggregates all class premiums, adds any policy fees, and applies taxes required by the state. The resulting figure is the annual premium the employer must pay. Some cost sheets also show a "Projected Premium" if payroll estimates change mid‑year.
Practical Tips for Employers
Understanding the cost sheet helps businesses manage expenses and improve safety. Consider these actions:
- Verify classification codes to avoid overpaying for a higher‑risk category.
- Maintain accurate payroll records; underreporting can trigger penalties.
- Implement safety training to lower the experience modifier.
- Review the sheet annually and negotiate with carriers if rates seem inconsistent.
