Chargeable Weight Worked Examples: 224 kg, 250 kg and 592 kg Cases
Four worked air-freight chargeable-weight examples using common planning divisors 6000 and 5000; confirm the actual carrier quote before booking.
Actual weight on the scale is not what the airline bills you. Air carriers and couriers charge on chargeable weight — the greater of actual gross weight and volumetric weight — and if you don’t work the numbers before you book, a light-looking pallet can invoice like a heavy one. This article walks through four real-world cases (224 kg, 250 kg, 592 kg and a decimal-rounding scenario) that answer the questions we hear most often, plus a density decision table you can screenshot.
The two formulas you actually need
Air-freight planning example:
Volumetric weight (kg) = L × W × H (cm) ÷ 6000
Express planning example:
Volumetric weight (kg) = L × W × H (cm) ÷ 5000
Divisors of 6000 and 5000 are common planning inputs, not universal rules. Confirm the divisor, rounding, minimums and per-piece method in the current carrier or service quote. The examples below use the larger of volumetric and actual gross weight under those stated assumptions.
For the 6000 planning example, actual weight wins above about 167 kg/m³ and volume below it. With 5000, the crossover is around 200 kg/m³; a quoted divisor changes the crossover.
Case 1 — 250 kg pallet, low density: volume wins
A 250 kg pallet measuring 120 × 100 × 150 cm.
- Volume = 120 × 100 × 150 = 1,800,000 cm³ = 1.80 m³
- Volumetric weight (6000 example) = 1,800,000 ÷ 6000 = 300 kg
- Actual gross weight = 250 kg
- Chargeable weight = 300 kg (volumetric wins)
- Density = 250 ÷ 1.80 = 139 kg/m³ → below 167, so volume wins
Under a quoted divisor of 5000, the same pallet would be 360 kg — 44% more than the actual weight. Do not apply that figure unless the live service quote uses 5000.
Case 2 — 224 kg, why chargeable > gross
A common Bing query: “chargeable weight bei Luftfracht 224 kg mehr als Gesamtgewicht” — why is my chargeable weight higher than 224 kg?
Suppose the shipment is 224 kg gross in a 100 × 100 × 160 cm crate.
- Volume = 100 × 100 × 160 = 1,600,000 cm³ = 1.60 m³
- Volumetric weight (6000 example) = 1,600,000 ÷ 6000 = 266.67 kg
- Chargeable weight = 267.0 kg if the quote rounds upward in 0.5 kg increments; 266.67 rounds to 267.0, not 266.5.
- Density = 224 ÷ 1.60 = 140 kg/m³ → below 167, volume wins
Answer: because your crate occupies the cargo space of a 267 kg shipment, even though it weighs 224 kg. The carrier sells cubic metres, not kilograms.
Case 3 — 592 kg dense cargo: actual weight wins
A machinery component, 592 kg gross, on a custom skid of 120 × 100 × 120 cm.
- Volume = 120 × 100 × 120 = 1,440,000 cm³ = 1.44 m³
- Volumetric weight (6000 example) = 1,440,000 ÷ 6000 = 240 kg
- Actual gross weight = 592 kg
- Chargeable weight = 592 kg (actual wins)
- Density = 592 ÷ 1.44 = 411 kg/m³ → well above 167
Under the stated divisor, these dense examples bill on actual weight. Recalculate under the booked service’s divisor, rounding and minimums before deciding where packaging work matters.
Case 4 — handling decimals
The table compares two possible rounding methods. Apply the 0.5 kg column only when the quote specifies upward rounding in 0.5 kg increments; a quote may instead use whole kilograms or another method.
| Raw calculation | Round to 0.5 kg | Round to 1 kg |
|---|---|---|
| 12.3 kg | 12.5 kg | 13 kg |
| 224.1 kg | 224.5 kg | 225 kg |
| 266.67 kg | 267.0 kg | 267 kg |
| 592.0 kg | 592.0 kg | 592 kg |
If a quote both assesses each piece separately and rounds each one upward in 0.5 kg increments, three 8.4 kg cartons produce 3 × 8.5 = 25.5 kg. Do not apply that per-piece method unless the booked terms say so.
Density decision table (screenshot this)
| Density (kg/m³) | 6000 planning example | 5000 planning example |
|---|---|---|
| < 100 | Very low: aggressive volume penalty | Same, worse |
| 100–167 | Volume wins | Volume wins |
| 167 (6000 break-even) | Tied | Volume still wins |
| 167–200 | Actual weight wins | Volume wins |
| 200 (courier break-even) | Actual wins | Tied |
| > 200 | Actual weight wins | Actual weight wins |
Rules of thumb:
- If your density is below 150 kg/m³, right-size the box before you ship.
- If it’s above 300 kg/m³, don’t waste time on packaging — the freight bill is what it is.
- If it’s between, run both formulas: the divisor decides who wins.
When should you switch from air to ocean?
There is no general 1000 kg or 6 m³ price crossover. Compare current all-in air and LCL quotes for the same origin, destination, packed dimensions, minimums, handling scope and deadline; either mode can win on a particular shipment.

Frequently asked questions
How do I calculate chargeable weight for air freight? For planning, multiply length × width × height in centimetres and divide by 6000. Then apply the divisor, comparison and rounding rules stated in the live carrier quote.
Why is my chargeable weight higher than the actual 224 kg? Because your carton occupies the cargo space of a heavier shipment. In the 6000 planning example, the volume conversion wins below about 167 kg/m³; confirm the booked service’s rule.
What is the chargeable weight of a 250 kg shipment? It depends on the dimensions and quoted divisor, not just the 250 kg. With divisor 6000, a 250 kg pallet at 1.8 m³ gives 300 kg; at 1.0 m³, actual weight wins.
How is chargeable weight calculated for courier services? Use the dimensional-weight rule in the current courier quote. A divisor of 5000 is a common planning example and gives a higher volumetric number than 6000 for the same box.
Is 6000 always the air-freight divisor? No. It is a common planning divisor: if quoted, 1 cubic metre converts to 166.67 kg volumetric. Use the divisor, rounding and minimums in the actual carrier quote.
The bottom line
Air freight billing is a density story: with planning divisors 6000 and 5000, the illustrative crossovers are ~167 and ~200 kg/m³. The booked service may differ, so measure every shipment and check the live quote. For a quick estimate, use our chargeable weight calculator; the chargeable weight guide explains the method.
