Formula Used
Base Premium = (Payroll ÷ 100) × Rate
Modifier Factor = (1 + ScheduleMod%) × (1 + OtherMods%)
Estimated Premium = (Base Premium × Modifier Factor × EMR) + Expense Constant
EMR reflects loss experience versus expected loss levels. This tool estimates how premium changes with EMR and modifiers.
