1. Cost per kilometre
Your all-in cost to move a truck one kilometre — fuel, driver, tyres, maintenance, EMI and overhead, divided by kilometres run. It is the single most useful unit-economics number in road transport because it lets you compare a 12-tonne truck against a 32-tonne multi-axle, an owned vehicle against a hired one, and this month against last.
Read it per vehicle and per lane, not just as a fleet average. A fleet average of ₹42/km can hide one vehicle running at ₹58 because of a slipping clutch and low mileage. The average looks fine; the vehicle is bleeding.
