The MWCARP (MA Workers' Compensation Assigned Risk Pool) Application Calculator is a tool designed to assist producers and employers in the calculation of workers’ compensation insurance assigned risk premium. We expect this tool will be helpful to producers and employers in calculating the appropriate premium amount to submit along with their Massachusetts Workers’ Compensation Assigned Risk Pool Application for insurance. A copy of the Application Calculation page may be printed and attached to a hard copy submission.

Please note this application does not access the WCRIBMA’s database for unique employer data, such as experience rating data. Therefore the calculation will be only as useful and accurate as the data that you enter. The application has been developed to cover the premium calculation requirements for the majority of assigned risk rules, programs and scenarios; but it is not the intention of this application to cover all rules, programs and scenarios. The premium developed from this application is intended to be a guideline, not the definitive and final premium.
