How the calculator works

InputWhat to enter
Vehicles listed per monthTotal Marketplace listings across all reps
Leads per listingMessenger conversations per listing, from your own history if you have it
Close rateShare of Marketplace leads that buy
Gross per unitAverage front plus back gross

Monthly gross = listings × leads per listing × close rate × gross per unit.

Rep time saved assumes about 12 minutes to type a listing by hand and about 1.5 minutes with LotBoard.

Getting honest inputs

These are your assumptions, not a promise. The value of the exercise is seeing which lever matters most for your store. Usually it's coverage (listings) and reply speed (close rate).
