Chargeable Weight Calculator
Calculate the billable weight a carrier is likely to rate across air freight, express courier, sea LCL W/M, and inland shipping planning modes.
Calculate Chargeable Weight From Dimensions and Weight
Chargeable weight is the weight a carrier bills for a shipment. It is usually the greater of actual/gross weight and volumetric/dimensional weight. Volumetric weight changes by mode: air freight commonly uses 6000 cm³/kg, express courier often uses 5000 cm³/kg, and sea LCL uses a W/M revenue-ton rule where 1 CBM is compared with 1 metric ton.
The default weight input is total shipment weight. Switch to per-piece weight only if the value entered is the weight of one identical package.
When you switch cm/kg to in/lb or back, the entered values are converted so a value such as 140 cm is never silently treated as 140 inches.
Mode comparison
Use the grid to see why the same carton can produce different billing numbers by mode. Sea LCL is shown in revenue tons, not kilograms.

Chargeable Weight, Actual Weight, Volumetric Weight, and Revenue Tons
The calculator separates the terms because they answer different questions. Actual weight is what the shipment weighs on a scale. Volumetric weight estimates how much network space the shipment consumes. Chargeable weight is the billable value after the carrier compares the relevant numbers. Sea LCL uses a revenue-ton comparison, often called W/M for weight or measure, so the final number is not a kilogram result.
| Term | Meaning | Why it matters |
|---|---|---|
| Actual / gross weight | Physical scale weight of the packed shipment. | Heavy dense products are usually billed on actual weight. |
| Volumetric / dimensional weight | Space-based weight from dimensions and a mode divisor. | Bulky lightweight products are often billed on volumetric weight. |
| Chargeable weight | The higher billable value after applying mode and carrier rules. | This is the number used in rate quotes and invoices. |
| Revenue ton / W/M | Sea LCL comparison between volume CBM and metric weight tons. | LCL freight often bills the higher of measure or weight. |
Which Chargeable-Weight Rule Should You Compare?
Air freight: 6000 ⇄ 166
International air freight commonly uses length × width × height ÷ 6000 in centimeters to estimate kilograms. In inches and pounds, the matching planning divisor is 166 in³/lb.
Express courier: 5000 ⇄ 139
Express and courier-style services often use 5000 cm³/kg, which produces a higher volumetric weight from the same carton. In imperial inputs, the matching planning divisor is 139 in³/lb.
Sea LCL: W/M revenue tons
For LCL, compare shipment CBM with weight tons. The output is revenue tons, such as 1.26 RT, because this billing basis is different from air or courier kilograms.
Road and inland: carrier-specific
There is no universal APAC road divisor. The 3000 cm³/kg row in this tool is optional and labelled as an inland or rail-style example, not a default road rule.
Use the Calculator Without Overstating Weight
Measure packed dimensions
Use the outside length, width, and height of the carton or pallet as it will be handed to the carrier. Include master cartons, pallets, overhang, void fill, straps, and protective packaging.
Choose the right weight basis
Leave weight as total shipment weight when the scale number already covers all pieces. Choose per piece only when each package has the same weight and the entered value belongs to one piece.
Compare modes before quoting
Use air, courier, and sea LCL rows to decide which carrier questions to ask. If road or inland freight is in scope, request the exact divisor instead of assuming a regional standard.
Pallet Example: 140 × 100 × 90 cm, 150 kg
A common air-freight pallet example is one pallet measuring 140 cm × 100 cm × 90 cm with 150 kg actual weight. The total volume is 1.26 CBM. Air freight at ÷6000 gives 210 kg volumetric weight, so 210 kg is chargeable. Express courier at ÷5000 gives 252 kg. Sea LCL compares 1.26 CBM with 0.15 metric tons, so the planning result is 1.26 RT before carrier minimums or rounding. The optional 3000 inland example gives 420 kg, but that is not a universal APAC road rule.
| Mode | Calculation | Result | Caveat |
|---|---|---|---|
| Air freight | 1,260,000 cm³ ÷ 6000 vs 150 kg actual | 210 kg chargeable | Rounding depends on the tariff. |
| Express / courier | 1,260,000 cm³ ÷ 5000 vs 150 kg actual | 252 kg chargeable | Parcel networks can apply their own dimension and weight rounding. |
| Sea LCL W/M | max(1.26 CBM, 0.15 weight tons) | 1.26 RT (revenue tons) | FCL is typically charged per container, not W/M. |
| Inland example | 1,260,000 cm³ ÷ 3000 vs 150 kg actual | 420 kg chargeable | Use only when a carrier rate sheet says this divisor applies. |
Chargeable Weight Formulas in cm, kg, inches, and pounds
For metric air freight, multiply length × width × height × pieces in centimeters, then divide by 6000 to get volumetric kilograms. For metric express courier, use the same cubic-centimeter volume but divide by 5000. For imperial air freight, multiply length × width × height × pieces in inches, then divide by 166 to get dimensional pounds. For imperial courier planning, divide cubic inches by 139. These pairs matter because 6000 cm³/kg maps to about 166 in³/lb, while 5000 cm³/kg maps to about 139 in³/lb. Reversing them makes quotes look artificially low or high.
The sea LCL row intentionally uses a different formula. It converts the shipment volume into CBM, converts actual weight into metric tons, and chooses the larger revenue-ton value. A shipment with 1.26 CBM and 0.15 metric tons is therefore 1.26 RT for LCL planning. That does not mean the shipment weighs 1.26 kg or 1.26 lb; it means the shipment is being rated on measure rather than weight. For full-container load moves, this W/M comparison is usually not the billing basis because FCL is commonly priced by container, lane, and service.
Where Chargeable Weight Changes the Commercial Decision
For ecommerce and D2C sellers, chargeable weight is often where a product that looks profitable in a landed-cost sheet becomes expensive in the real carrier invoice. Apparel, accessories, beauty kits, homeware, toys, and giftable bundles can be physically light but bulky after protective packaging is added. A carton that weighs only a few kilograms can rate much higher when it moves through an express network, especially across borders where dimensional weight, fuel surcharge, remote-area fees, customs handling, and minimum charges stack together.
The practical workflow is simple: measure the packed shipping carton, check the chargeable weight before requesting quotes, compare air and courier outputs when delivery speed is flexible, and use CBM when deciding whether sea LCL is worth the slower transit time. If the chargeable number is much higher than scale weight, packaging optimization may save more than carrier shopping. Reducing carton height, removing void fill, right-sizing master cartons, or splitting a bulky assortment differently can lower billable weight without changing the product itself.
Quote request checklist
Share pieces, outside packed dimensions, total actual weight, CBM, requested mode, origin, destination, and whether the weight is per piece or total shipment weight. Ask the carrier or forwarder to confirm divisor, rounding, minimum charge, and whether the lane is billed by actual weight, volumetric weight, or sea LCL revenue tons. Keep that confirmation with the quote so finance can reconcile the invoice later.
Rounding Is Carrier- and Tariff-Specific
This calculator computes and displays exact values rather than inventing a rounding increment. Some parcel services round dimensions before calculating dimensional weight. Some air-freight tariffs round billable weight upward. Some LCL forwarders apply minimum revenue tons or display invoice lines to a fixed number of decimals. Those rules are commercial terms, not universal math. Treat the numbers here as planning outputs, then confirm divisor, minimum, and rounding rules against the actual carrier or forwarder rate sheet before booking.
Why There Is No Chargeable Weight Calculator Excel Download
Searchers often ask for a chargeable weight calculator in Excel, but a live calculator is safer for this job. Spreadsheet files drift, old divisors get copied into new lanes, and unit mistakes are easy when centimeters, inches, kilograms, pounds, CBM, CFT, and revenue tons sit in adjacent columns. This page keeps the mode assumptions visible, converts units when switching systems, and separates sea LCL revenue tons from air or courier weight results. If you need to share the output, use the copy button and paste the summary into a quote request, carrier comparison, or internal shipping note.
