Freight Cost Per Kg

What freight cost per kg tells you

Freight cost per kilogram expresses a shipping charge as a single rate, so you can compare quotes from different carriers and see how cost changes with shipment size. It is a comparison tool, not a published tariff — the same lane can show very different per-kg rates depending on weight, volume and service.

The formula

Include only the freight charge you want to compare. If you also want an all-in figure, add surcharges and handling separately so the base rate stays comparable across quotes.

Use chargeable weight, not just actual

Carriers bill on chargeable weight — the greater of actual and volumetric weight. Dividing by actual weight when the shipment is billed on volumetric weight understates the real per-kg cost. Work out chargeable weight first (see the volumetric vs chargeable weight guide), then divide.

Worked example: comparing two quotes

Illustrative figures only — not carrier rates.

The totals differ, but on a per-kg basis the two quotes are identical — the difference is chargeable weight, not price efficiency. Per-kg makes that visible.

Why per-kg falls as volume rises

Fixed costs and minimum charges are spread over more weight as shipments grow, so per-kg usually drops with volume. That is why a small trial order can look expensive per kilogram and a full container far cheaper. Compare like-for-like shipment sizes when judging quotes.

Before you calculate: checklist

• The total freight charge you want to compare.
• The chargeable weight (worked out from actual and volumetric weight).
• Which surcharges are included in, or excluded from, the total.
• The shipment size, so you compare like-for-like.

Common mistakes

• Dividing by actual weight when the shipment is billed on volumetric weight.
• Comparing an all-in quote against a base-rate quote.
• Ignoring minimum charges on small shipments.
• Comparing per-kg across very different shipment sizes.

Assumptions and limitations

Per-kg is a comparison metric, not a fixed rate. Carriers price on lane, service, fuel, surcharges and minimums that change over time. The figures here are illustrative; use your own quotes.

What UtilityPilot can calculate

The freight cost per kg calculator divides total charge by chargeable weight for you. Work out chargeable weight first with the chargeable weight calculator, then fold the result into the landed-cost workflow.

What you must verify

Confirm the charge, the chargeable weight and which surcharges are included with your carrier. UtilityPilot estimates from the figures you enter; it does not supply carrier rates.
