Key factors in work comp calculation
The cost of workers compensation insurance is based on several critical factors, including:
Classification code (Class code): The classification system assigns a unique class code to each business based on its industry and risk level. For example, construction companies have higher class code rates than office-based businesses.
Actual payroll & employer's payroll: The employer's actual payroll is used to determine workers comp premiums. Employers should ensure accurate reporting to avoid overpayment.
Experience modification factor: Also known as experience modification, this factor is determined by the company’s claims history. A lower claims history results in lower insurance premiums.
State fund & workers compensation Laws: Each state has different regulations regarding workers compensation insurance cost. Some states allow private insurance companies, while others require businesses to purchase from a state fund.
Employer classification & business size: The employer classification and number of full-time employees or seasonal hires affect the workers compensation rate.

Workers compensation formula explained
The basic formula to calculate workers comp is:
Workers Comp Cost = (Actual Payroll / 100) × Class Code Rate × Experience Modification Factor
For example, if a business payroll is $500,000, the class code rate is $1.75, and the experience modification factor is 1.1, then:
($500,000 / 100) × $1.75 × 1.1 = $9,625 per year
This formula ensures that businesses pay premium payments proportionate to their risk exposure.
Work comp calculation examples
Calculating workers compensation benefits is essential for ensuring that employees receive the financial support they need in the event of a work-related injury or illness.
Here's an overview of how to calculate workers comp premiums for both temporary and permanent disabilities.
Example: Temporary disability calculation
If an employee earns an average weekly wage of $1,000 and the state mandates 66.67% coverage for temporary disability, then:
$1,000 × 66.67% = $666.67 per week in workers compensation benefits.
Example: Permanent disability compensation
If an employee is deemed totally disabled, their benefit amount is calculated based on their average weekly wage and eligible compensation period.
For instance, if their average weekly wage is $1,200 and the maximum benefit period is 500 weeks, the total payout is:
$1,200 × 500 = $600,000 in total compensation.
This helps cover medical treatment, rehabilitation, and long-term support.
State differences in work comp calculations
Each state has unique workers compensation laws that impact workers compensation costs. Employers must follow state-specific regulations to ensure compliance. Each state has its own classification system, classification code, and experience modification factor, which influence how workers comp premiums are calculated.
Some states require businesses to purchase coverage from a state fund, while others allow policies from private insurance companies. Additionally, differences exist in employer classification, pay-as-you-go options, premium payments, and claims history requirements.
How to check your state’s workers’ compensation rules
Employers can:
Visit their state’s workers compensation policy website.
Check the assigned classification code and experience modification factor.
Compare costs with private insurance companies and the state fund.
Some states offer a pay-as-you-go option, allowing employers to make premium payments based on actual payroll, rather than projected payroll. This improves employer’s cash flow and reduces the risk of unexpected bills.
