How much does this particular tractor cost, per month and per kilometre?
A machine’s cost broken down by item, depreciation drawn from the price entered once, the machine tied to supplier bill lines, and a dash when a figure is missing.
What you get
- The cost per kilometre of each tractor, in view when you price a trip.
- Insurance and leasing tied to the machine, not lost in overheads.
- Keep or sell: a decision based on figures, not on gut feeling.

Half of your decisions are not about a trip but about a machine: keep it or sell it, put it on long-haul lines or on shuttles. For that you need one figure: what this particular tractor costs per month and per kilometre.
Depreciation is derived from what you enter once: purchase price and date, service life, residual value. When the service life is over, it honestly drops to zero, and the card says so: fully amortized.
The cost is broken down by item: fuel, crew, depreciation, maintenance, tyres, tolls, insurance, leasing. Each one shows where it came from: bills, fuel log, commitment, payroll share. And the kilometres are odometer readings from the fuel log, and the card labels them so.
Every line of a supplier bill asks two independent questions: which trip and which machine. Insurance belongs to the tractor, the ferry to the trip, a roadside repair to both. Linking a machine does not move the trip margins: it is one more reading of the same documents.
And if nobody entered the machine's price, depreciation shows a dash, and the card says what is missing and what to fill in. It does not give a cost per kilometre until everything is known, only the bills figure, labelled as such. No invented average, no zero.
The figures of one specific machine — not a fleet average.
