The September 1, 2022 Experience Modification Estimator is now available on the Workers’ Compensation Insurance Rating Bureau of California (WCIRB) website. This Estimator is an application that makes it easy to estimate experience modifications (X-Mods).
The Experience Modification Estimator relies on payroll and loss information that you enter. The estimated X-Mod is for informational purposes only; because results are dependent upon the information you enter, they may differ from the actual X-Mods issued by the WCIRB.
The Experience Modification Estimator can be accessed for free in the Learning Center of wcirb.com or through the link below:
For detailed instructions on how to use the X-Mod Estimator, review the Help Guide available on the first tab of the Experience Modification Estimator Excel file. A helpful shortcut sheet featuring an abbreviated version of the instructions is also available on the Experience Modification Estimators page.
