Retro Premium Calculator

Current Premium Calculator (1 MB XLS)

This calculator assists in projecting future retro performance (though projections are not guaranteed). Please email Retro@Lni.wa.gov with questions about the calculator.

Last updated July 2017.

Retro Premium Calculator (673 KB XLS)

This premium calculator is meant to be used for coverage periods from July 2014 through April 2017. Unlike the current premium calculator above, this calculator does not reflect recent changes to the Retro insurance tables and single loss limit program rules.

Last updated July 2017.

Retro Prior Premium Calculator (1616 KB XLS)

This premium calculator is meant to be used for coverage periods prior to July 2014. Unlike the updated Retro Premium Calculator this calculator still utilizes the Performance Adjustment Factor (PAF) in the net insurance charge under premium based plans.

Last updated November 2014.

Significant dates, deadlines, and a schedule of report publications, can be found in our Retro 2017 dates and deadlines (945 KB PDF) calendar. Please contact retro with any questions or comments about the calendar.
