Formula used

Step 1: Build a scenario base premium.

ScenarioBase = BasePremium × CoverageFactor × VehicleFactor × DeductibleFactor × MileageFactor

Step 2: Combine surcharge components into a total surcharge rate.

SurchargeRate = StateBaseline + DUISeverity + BACSeverity + Recency + Profile + Extras

Step 3: Apply discounts, then apply the surcharge.

DiscountedBase = ScenarioBase × (1 − DiscountRate)

EstimatedPremium = DiscountedBase × (1 + SurchargeRate)

This tool caps DiscountRate at 15% and SurchargeRate at 300% to keep estimates readable.
