CBM Calculator for Amazon FBA Shipping
Answer: CBM = length × width × height in meters × carton quantity. For centimeter inputs, divide length × width × height × quantity by 1,000,000.
What is CBM for FBA shipping?
CBM is the cubic-meter volume of your packed cartons. FBA forwarders use it to quote ocean LCL, check whether FCL makes sense, and compare volume against chargeable weight for air freight planning.
How to calculate CBM
For centimeter inputs:
| Step | Formula |
|---|---|
| One carton | length cm x width cm x height cm / 1,000,000 |
| Total shipment | one-carton CBM x carton quantity |
Example: 80 cartons at 50 x 40 x 30 cm = 4.8 CBM.
When CBM is not enough
CBM does not include commodity restrictions, battery handling, customs duty, Amazon appointment timing, or destination fees. Use it as the volume input for a quote, not as the final freight price.

Should I use product size or carton size?
Use packed outer carton dimensions because forwarders quote from the measured export carton, not the product inside.
Does CBM decide the final freight cost?
No. CBM gives the volume line. Final freight also depends on lane, cargo type, Incoterms, customs, and delivery address.
How much CBM fits in a 40HQ?
A 40HQ is usually planned at about 65-68 usable CBM for boxed ecommerce cargo, depending on carton fit and weight limits.
