Complete Guide to Workers' Compensation Premium Calculation

Why This Question Matters for Colorado and Utah Residents

Understanding how your workers' compensation premiums are calculated is crucial for Colorado and Utah business owners. These premiums directly affect your operating costs and are influenced by local industry risks and regulations unique to our region.

  • Payroll Size: Your total payroll sets the foundation since it represents your exposure level. Larger payrolls mean higher potential claims and thus higher premiums.
  • Job Classifications: Each job role is assigned a classification code reflecting its inherent risk. For example, construction roles common in Colorado mountain towns carry higher risk than clerical jobs found in Denver or Salt Lake City offices.
  • Industry Risk Factors: Some industries like agriculture in Northern Colorado or manufacturing in Utah have elevated hazard levels that impact premium rates.

What Most People Get Wrong

Many business owners underestimate how significantly job classifications affect premiums. Incorrectly classifying a moderately risky job as low risk can result in insufficient coverage or costly audits later.

Others overlook their claims history impacting premiums through the experience modification rate. A strong safety record can reduce premiums, but frequent claims will raise them substantially.

The Complete Picture

Workers' compensation premiums are calculated by multiplying your payroll by the rate assigned to each job classification. Those rates are influenced by your industry’s historical claim experience in Colorado and Utah. Insurers then adjust this amount by your company's experience modification rate, which compares your claims history to the industry average.

For example, a manufacturing company in Colorado Springs with $1 million in payroll categorized partly under high-risk classifications like machine operation, and a low claims history, may benefit from a favorable experience mod rate, lowering premiums significantly. Conversely, a Utah construction firm in Park City with similar payroll but a poor claims record will face higher premiums.

Key Point: Accurate payroll records, proper job classification, proactive safety management, and regular claims review in consultation with your FoCoIns advisor can lead to substantial premium savings and better coverage.

Making the Right Decision for Colorado and Utah Residents

Question 1: Are all your employees correctly classified according to their actual job duties?

Ensure that each employee's job classification matches their real work. Misclassification can lead to underpayment of premiums or costly penalties. Regularly update classifications as roles evolve.

  • Review job descriptions and duties carefully.
  • Consult with your insurance advisor to verify classifications.

Question 2: How does your claims history affect your premium?

A strong safety record can lower your experience modification rate, reducing your premium. Evaluate incident reports and implement safety programs to improve claims performance.

Question 3: Is your payroll accurately documented and compliant with local regulations?

Keep detailed and accurate payroll records, including overtime and subcontractor information if applicable. This transparency ensures fair premium calculation and avoids surprises.
