How is Workers' Comp Calculated?
Workers’ compensation is a commercial insurance product categorized as Property & Casualty insurance (P&C Insurance). Even though workers’ comp is calculated using estimated payroll wages and class codes, premium is still a separate business expense from the cost of payroll. Washington Employers may treat the cost of coverage as an expense on their taxes.
Work comp rates for all job classification codes are always expressed as a percentage of $100 in wages. An annual policy is always subject to an audit because it was based on estimated wages and not actual wages.
Here is an example using two class codes with different estimated payroll for each class code:
In order to calculate the cost of the policy you only need to multiply each rate with its divided payroll. It benefits employers to re-calculate their premium as their payroll becomes larger than originally anticipated.
