When a business owner wants to know what delivery costs, they usually look at the carrier’s receipt. There’s a number on it, and it feels like the answer. At LPF we’ve been running logistics day in, day out since 2018, and we see that this is almost always a mistake. The number on the receipt is only the tip. The real cost of delivery hides in a dozen small expenses that each look trivial on their own, yet together eat your margin quietly and out of sight.

To see this picture honestly, you need one simple unit of measurement: cost per kilogram. Not “what this parcel cost,” not “what we paid the carrier this month,” but what it actually costs to move one kilogram of your product from the shelf to the customer, with everything that revolves around it. Once you can see that number, a lot of decisions make themselves.

In this article we’ll unpack why the receipt lies, what your real cost per kilogram is made of, and how to calculate your own.

Why the receipt isn’t your cost

The carrier’s receipt shows the rate for one specific shipment. But delivery isn’t just the moment the parcel is in transit. It’s the whole chain around it, and every link costs something.

  • People’s time. Someone picks the order, packs it, fills in the waybill, answers “where’s my parcel?” Those minutes are money too — they’re just not on the receipt.
  • Packaging. Boxes, wrap, tape, filler. Pennies per parcel; a real sum across a thousand.
  • Returns and failed deliveries. The customer didn’t collect it — you pay the round trip, and the goods come back scuffed.
  • Damage and breakage. Especially for fragile or heavy items: some of it never arrives in sellable shape.
  • Money frozen in transit. While the parcel travels and waits at the branch, your cash for it isn’t in your hands yet.

None of these numbers appear on the receipt. So an owner who counts only the rate almost always underestimates the true cost — sometimes by half again as much.

Why per kilogram, not per parcel

Counting “per parcel” sounds simpler, but that unit lies. One parcel might weigh two hundred grams, the next five kilograms, and comparing them is pointless. Cost per kilogram removes that mismatch and gives you a single ruler you can measure everything against.

  • It compares the incomparable. Different products, different cities, different carriers — all reduced to one figure.
  • It shows where you’re losing. A light item that’s expensive to ship stands out instantly: its cost per kilogram is sky-high.
  • It talks to your product price. If shipping a kilogram costs as much as a kilogram of the goods, that’s a signal to rethink either the price or the shipping method.

That’s why, whenever we take on someone’s logistics, our first step is always to reduce everything to this unit. It’s impartial, and it leaves nowhere to hide behind “roughly this much overall.”

How to calculate your honest number

The idea is simple, though it takes some care with the data. You take a real period — a month or a quarter — and gather every cost tied to delivery, not just the payment to the carrier.

  • Collect all costs for the period. The carrier’s rate, packaging, wages for the time spent on logistics, the cost of returns and losses.
  • Count the actual weight you shipped. The total kilograms across every shipment in that same period.
  • Divide one by the other. Total costs over total weight gives you an honest cost per kilogram.
  • Break it down by segment. Count heavy and light goods separately, and different regions — and you’ll see where the loss is hiding.

The main trap here is the temptation to leave the “inconvenient” costs out because they’re hard to count. But those are exactly the ones that make the number honest. Half the point of the exercise is to bring into the light what usually dissolves into the business’s general expenses.

What this number changes right away

Once cost per kilogram is calculated honestly, decisions stop being a matter of gut feeling.

  • You see which products are unprofitable to ship — and whether they belong in your delivery range at all.
  • You see where free shipping is a gift to yourself at a loss, and where it genuinely pays off through volume.
  • You see when counting by hand has grown more expensive than automation — and waybills should be created automatically, not by human hands.
  • You see the truth in negotiations with a carrier — because you speak in numbers, not impressions.

We walk this path both in our own daily logistics and alongside our clients. Often the first honest number comes as a surprise — and that surprise is where the most useful changes begin.
