Workers’ comp premium is calculated as payroll × class code rate × experience modifier. Class codes vary dramatically by manufacturing type:

· Light assembly / packaging: $0.50–$1.50 per $100 of payroll
· Food manufacturing: $1.50–$5.00 per $100
· Metal fabrication: $4.00–$12.00 per $100
· Heavy machinery / structural steel: $8.00–$15.00+ per $100

For a small manufacturer with $400,000 in payroll, that translates to anywhere from $2,000 (light assembly) to $30,000+ (heavy fabrication) annually. Experience modifier can swing the premium 25%+ in either direction based on three-year claims history. We help structure safety programs, classify employees correctly, and shop across carriers with different appetites for your class code.
