Cost-Per-Tonne-Kilometre: The Number That Should Drive Every Haulage Decision
Most haulage contracts are negotiated on gut feel. Here's the single metric that turns freight strategy into a science.
Ask most operators how they chose their haulage contractor and you'll hear about relationships, availability, or a quote that felt reasonable at the time. Almost none will mention cost-per-tonne-kilometre — and that's exactly why so many freight budgets quietly bleed margin.
What the number actually captures
Cost-per-tonne-kilometre (cost/t-km) normalises freight spend against the two variables that actually matter: how much you're moving, and how far. A contractor charging more per kilometre but running fuller loads and shorter empty-return legs can easily beat a 'cheaper' quote once you do the math properly.
Where operators get it wrong
The most common mistake is comparing headline rates instead of landed cost per tonne delivered. Fuel surcharges, border delays, empty-leg repositioning, and demurrage all belong in the denominator, not as footnotes. Once you build those into the model, route rankings often flip entirely.
Turning this into a decision
The teams that get real value from this metric track it monthly, by route and by contractor, and use it as the basis for renegotiation — not as a report that sits in a folder. It becomes a genuine lever the moment procurement and operations both look at the same number before a contract is signed.
