WCIRB Experience Modification Estimators

Printer-friendly version

The Experience Modification Estimators (Estimator) are Excel-based applications for insurers, agents and brokers to help policyholders understand how experience modifications are computed and the likely impact of the 2017 experience rating formula change on a policyholder’s modification. The estimated experience modifications resulting from these applications rely on payroll, classification and claims information supplied by the user. Actual classifications, payroll and claims amounts used by the WCIRB to calculate an experience modification may be different. 

  • 2016 Experience Modification Estimator
    This application will estimate an experience modification based on the payroll and loss data entered by the user in the “X-Mod Calculation Inputs” tab, and the 2016 approved Experience Rating Plan expected loss rates, D-ratios, $7,000 fixed primary threshold and credibility values.
     
  • 2017 Experience Modification Estimator
    This application will estimate an experience modification based on the WCIRB’s approved 2017 Experience Rating Plan values including expected loss rates, D-ratios, primary thresholds that vary by employer size  and credibility values that have been approved by the California Insurance Commissioner. The user will see the estimated likely impact of the change from the $7,000 fixed split point plan to the 2017 variable split point plan on an individual employer's experience modification. As with the 2016 Estimator, the estimator will rely on payroll, classification and claims information supplied by the user.
     

Users will get detailed printable results for each estimated experience modification. User-entered data can be copied and pasted between the two Excel spreadsheets. The Estimator is for informational purposes only. Results are only estimates and not published experience modifications. For help on any of the Estimator’s features and tips on obtaining an accurate estimate, open the Help Guide available on the first tab as a downloadable PDF.
