Owner Exclusion and Rating Mechanics
Owner exclusion changes which individuals are treated as covered payroll in a workers compensation estimate. When owners are excluded, their payroll basis is removed from the manual premium, but other charges may remain. This calculator shows both outcomes side by side so you can quantify the financial effect before requesting endorsements or filing elections.
Estimating Manual Premium with Payroll Bases
The model starts with non‑owner payroll, converted to premium using a rate per $100. If owners are rated, each owner’s payroll basis is bounded by minimum and cap values to reflect common underwriting programs. When the owner detail table is enabled, each active row can carry its own payroll, rate, and factor, supporting mixed roles or entity structures.
Modeling Credits, Loads, and Minimum Premiums
After manual premium, the calculator applies experience modification and schedule credit or debit to estimate the modified premium. Then it applies premium discount and other credits, either combined or sequential, depending on your worksheet convention. Optional carrier factor, deductible credit or debit, and catastrophe load refine alignment. The minimum premium can apply before fees or after fees.
Interpreting Included vs Excluded Scenarios
Included results typically show higher totals because owner payroll is included in the manual basis. Excluded results remove owner basis, but may add a residual owner charge if your program requires it. The breakdown table shows component differences, helping you identify whether savings come from payroll removal, discount interactions, or minimum premium constraints.
Documentation, Exports, and Renewal Use
Use exports to keep a clear audit trail. Download CSV for scenario comparison and budgeting, and download PDF for approvals and renewal discussions. Store the report with payroll summaries and prior worksheets. At renewal, update payroll, modifiers, and fees, rerun the calculator, and measure how ownership elections shift projected totals. Validate assumptions by running low, expected, and high payroll cases. When totals are close to the minimum premium, exclusions may not change pricing much. Adjust inputs to mirror your worksheet.
