Annual vehicle activity
These two figures serve as a basis for the calculation: the annual mileage allows us to reduce the fixed costs per kilometer, the days of operation give the price per day.

What is this price per kilometer calculator for?
The price per kilometer is the most telling indicator in road transport: it is the reference for establishing a quote, comparing an offer, negotiating with a client or deciding whether a tour is worth the trip. You still have to start from your real costs, and not from a “market” price which can make you work at a loss.
This free calculator determines, in four guided steps, your cost price per kilometer then the recommended selling price per km depending on the margin you are targeting. It applies the logic of cost per kilometer, the reference method of the National Road Committee (CNR) used in all road freight transport.
It is aimed both at the craftsman who wants to cost a journey and at the operator of an SME or mid-sized company who is looking to build a coherent price list. No registration, no data sent: the result is instantly displayed on the screen.
How to use the calculator
- 1
Enter the activity
Annual mileage and vehicle operating days: these are used to reduce fixed costs per kilometer.
- 2
Enter your variable costs
Fuel (consumption × price), tires and maintenance-repairs, expressed per kilometer.
- 3
Add your fixed costs
Depreciation and financing, insurance, taxes and cost charged to the driver, over the year.
- 4
Fix structure and margin
Overhead costs as a percentage then your margin: the recommended selling price per km is immediately displayed.
The cost per kilometer method
The price per kilometer is calculated by reducing the annual operating cost of the vehicle to the distance traveled, then adding overhead costs and your margin:Selling price = (Variable costs + Fixed costs) × structure × margin. This is the logic of the CNR benchmark: we distinguish what varies with the kilometers from what remains fixed, before applying structure and margin.
Variable costs
Charges proportional to distance, expressed per kilometer: fuel (consumption × price), tires and maintenance-repairs.
Fixed costs
Annual charges independent of mileage, reduced per km: depreciation and financing of the vehicle, insurance, taxes and cost charged to the driver.
Structure & marge
General expenses (operations, management, sales) applied as a percentage of the operating cost, then your commercial margin to obtain the selling price.
Can we trust this price per km?
The kilometric cost method is the one that the CNR follows to publish its indices. Correctly informed, it gives a solid floor price below which you lose money. What to keep in mind:
What makes the calculation reliable
- A standardized method recognized throughout road transport (CNR reference).
- The separation of variable costs/fixed costs reflects the economic reality of a vehicle.
- The recommended price includes your structural costs and your margin, not just the rolling costs.
What it does not replace
- Empty kilometers and unloaded returns, which degrade the price per actual km.
- Expectations, load breaks and operating hazards specific to each mission.
- Long-term monitoring: a fair price per km is based on your actual costs.
Beyond calculation: invoice at the right price with Signal
This calculator gives you a reliable price per km. For it to stick to reality and translate into invoices, it must be fed with your operating data. This is the role of Signal, the simple and complete TMS designed for road transport of goods.
The real cost per kilometer
Mileage, consumption, maintenance and depreciation per vehicle: your price per km is based on real figures, not averages.
From the calculated price to the invoice
Register your transport at the right price and produce your invoices based on your prices: no more journeys sold below their cost.
Your actual kilometers
Each transport and its distance are centralized: you follow the kilometers actually traveled, empty and loaded.
Estimated versus realized
Compare the planned price per km to what the mission actually cost, and refine your price scale over time.
A TMS that goes against historical software
Traditional transportation management solutions are expensive, cumbersome and reserved for large groups. Signal takes the opposite view.
Easy to handle
A clear interface, designed for operators. You are up and running in minutes, without training lasting several days.
Complete, without gas plant
Vehicle costs, transport, eCMR, tracking and invoicing combined — without modules to assemble or hidden options.
Accessible to all
A free offer that can be used and predictable prices depending on your team. From the craftsman to the mid-sized company.

Frequently asked questions about price per kilometer
How to calculate the price per kilometer of transport?
We add the variable costs per km (fuel, tires, maintenance) and the fixed costs per km (depreciation, insurance, taxes, driver), we apply a percentage of structural costs, then a margin. The total gives the selling price per kilometer. This is exactly the calculation carried out by this tool.
What is the right price per km for a heavy goods vehicle?
There is no universal price: it depends on your vehicle, your annual mileage, your charges and your margin. A 40 ton unit does not cost the same price per km as a carrier. The right approach is to start from your real costs – that is the role of this calculator – rather than a “market” price.
What is the difference between cost price per km and selling price per km?
The cost price per km is what the kilometer costs you. The selling price per km is what you charge: cost price + structural costs + margin. Invoicing at cost means driving without profit. The tool displays both, so you aim for the right price.
How to set your margin on the price per kilometer?
The margin is a commercial choice: it covers your risk, your development and your remuneration. Test several rates in the calculator to see the effect on the selling price per km, and position yourself without ever falling below your cost price.
What costs are included in the price per kilometer?
The variable costs (fuel, tires, maintenance-repairs), the fixed costs of the vehicle (depreciation, financing, insurance, taxes), the cost of the driver, then the general costs of the company. The annual mileage is decisive: the less you drive, the more the fixed costs weigh on each kilometer.
Is the price per km the same for all journeys?
No. A trip with an empty return, waiting or low use of the vehicle is more expensive per kilometer than an optimized rotation. The calculator gives a reliable basis; then adjust it according to the real context of each mission.
