The empty return: the 44% of the rate nobody quotes

What the empty return actually is

A full-truckload move has three movements, not one: the loaded leg you contract, the truck's return toward wherever it finds its next load, and the tractor's reposition to the pickup point. If the carrier finds a return load (a backhaul), that other cargo pays for the return. If not, the truck goes back empty — burning diesel, paying the driver and tolls — and that cost is spread over the only rate that funds it: yours.

That's why two quotes that look identical can describe very different trips. On Bogotá → Medellín the engine gives US$985 with no return load and US$550 with a secured backhaul: the difference — 44% of the rate — isn't in the truck or the road; it's in an assumption almost nobody writes down.

The three scenarios that must be declared

The engine models the return in three scenarios, and the gap between worst and best exceeds a third of the rate on almost every corridor:

No return. The truck comes back empty over the whole corridor. It's the conservative, most expensive assumption — and the one a model makes when nobody says otherwise.

Partial return. The carrier finds cargo for part of the way back, or a lower-value leg. The norm on corridors with imbalanced flow.

Secured return. There's committed return cargo: the outbound rate only pays for the outbound. It's what a carrier with a dense network can offer — and what justifies a lower price without quoting below cost.

The consequence for procurement is direct: a low rate with a secured return and a high rate with no return can both be fair. What isn't fair is paying the high rate to a carrier that does have a backhaul.

Where it weighs most: export, import and imbalance

The empty return weighs according to the direction of flow. On an export corridor — Guatemala → Tecún Umán toward Mexico, or any lane toward a border — a lot of cargo goes out and little comes back: the empty-return premium is high. On an import cycle from a port, Buenaventura → Bogotá, the empty return is the rate's second line (21%), right behind fuel (24%). And on short corridors the effect explodes: on 200 km in Costa Rica, the empty return (US$178) exceeded fuel itself (US$103), because the reposition doesn't shrink with the route.

Return tolls: the line that's charged but never seen

Here's the detail that slips through most. When the truck comes back empty, it pays tolls on the way back — and that cost usually enters the total without appearing on any line. On Bogotá → Medellín we found US$113.72 of empty-return tolls, about 12% of the rate, inside the total and outside the breakdown. It wasn't wrongly charged; it was wrongly shown. And a breakdown that doesn't reconcile to the total lets you audit nothing. Demand that return tolls get their own line.

What it looks like in a well-made quote

An honest quote separates the loaded leg from the return, writes down the assumed backhaul scenario, and breaks the return into its components: return diesel (at the price of the country it returns through — on a cross-border corridor, the return diesel isn't the origin's), driver, and return tolls. With that, you can ask the question that changes the negotiation: "Does this price assume you come back empty? Because your network has freight on that corridor."

What to demand about the return in every quote

• The backhaul scenario written down: no return / partial / secured.
• The return as its own line, separate from the loaded leg.
• Return tolls itemized — not inside the total, unseen.
• Return diesel at the price of the country it comes back through, on cross-border lanes.
• The full breakdown summing exactly to the total.

A low rate with a secured return and a high rate with no return can both be fair. What isn't fair is paying the high one to a carrier that does have a return load.
