Workers Comp Rates in South Carolina

Workers compensation premiums in South Carolina are calculated based on payroll, job classification (NCCI or state classification codes), and the employer's experience modification factor. The average rate of approximately $1.62 per $100 of payroll is a statewide blended average — actual rates vary significantly by job classification. A clerical office worker might pay $0.20-$0.40 per $100, while a roofing contractor might pay $15-$25 per $100.

For example, an employer with $1 million in payroll at the average rate of $1.62 per $100 would pay approximately $16,200 annually before experience modification adjustments. Employers with better-than-average loss experience (experience mod below 1.0) pay less; those with worse experience pay more.

How Workers Comp Premiums Are Calculated in South Carolina

Workers compensation premiums in South Carolina follow this basic formula: (Payroll / 100) × Classification Rate × Experience Modification Factor = Premium. The experience modification factor (EMR or X-Mod) compares your actual loss experience to the expected loss experience for your industry. An EMR of 1.0 is average; below 1.0 means better-than-average safety record (lower premiums); above 1.0 means worse-than-average (higher premiums).

Job classification codes are assigned based on the type of work employees perform. Accurate classification is critical — misclassifying employees into lower-risk categories can result in premium audits and significant back-premium assessments. An employer with employees in multiple classifications must track payroll by class code throughout the year.

How to Reduce Workers Comp Costs in South Carolina

South Carolina manufacturing employers should work with insurers experienced in automotive and aerospace workers' comp. Safety programs for the state's growing manufacturing sector reduce injury rates and premiums. Experience modification management through strong safety training and return-to-work programs is highly effective.

• Implement a formal workplace safety program — documented safety training reduces injury frequency and improves experience modification over time.
• Develop a return-to-work program — getting injured workers back on modified duty reduces temporary disability claim duration and cost.
• Report all injuries promptly — early reporting enables timely medical treatment and claims management, reducing claim severity.
• Review job classifications annually — ensure employees are classified in the correct (not simply the lowest-cost) classification code.
• Work with a loss control specialist — many insurers offer free safety consultation services that identify hazard reduction opportunities.
