Add-on load calculator: is the extra part load worth the detour?
Enter your route without and with the add-on, your cost per kilometre, the extra toll and the price offered. The calculator shows what the add-on really earns, its margin, the money per extra kilometre and the lowest price at which it still pays.
Result
How the calculation works
- Extra kilometres = route with the add-on minus route without it.
- Extra cost = extra kilometres × your cost per km + extra toll.
- What the add-on earns = price offered − extra cost; the margin is that share of the price.
- Minimum price = extra cost ÷ (1 − minimum margin): below it the add-on does not clear your margin.
- An add-on that makes the main load late is a loss whatever it pays — check the delivery window first.

FAQ
How do I price an add-on (part load)?
Charge at least the detour it causes: extra kilometres times your cost per kilometre plus extra toll, then your margin on top. The minimum price above does exactly this.
What cost per kilometre should I use?
Your full cost per kilometre — fuel, tolls you always pay, driver, truck and overheads divided by the kilometres driven. Many small carriers land between €1.00 and €1.40 per km.
When is an add-on a bad idea even if it pays well?
When it makes the main load late, needs a body or space the truck does not have, or carries dangerous goods the truck is not equipped for.
