Quick Facts

What is a ratings calculator?

In California workers' compensation, a ratings calculator is a tool used to estimate the level of permanent disability (PD) for an injured worker. The rating represents the degree to which a work-related injury affects the workers' ability to perform their jobs and impacts their future earning capacity. The disability rating is expressed as a percentage, with 100 percent meaning total disability.
