Volumetric weight, CBM and pallet estimator

Automatically calculate volumetric weight (selectable factor), CBM, and estimated pallet count from box dimensions, weight and quantity.

Factor, rounding and minimum billable weight vary by carrier and transport mode.

How to use

  1. Enter dimensions, weight and quantity in the box type table. Unit suffixes are supported.
  2. Set factor, rounding and calculation mode (per piece or total).
  3. Set pallet conditions (preset, height and optional weight limit).
  4. Check summary and breakdown, then share with copy, CSV or share URL.

Sample

Air freight estimate
Input: Box A 40x30x20cm, 10kg, qty 10 / factor 6000 / per piece
Output: Total CBM 0.240, total volumetric weight 40.0kg, chargeable weight 100.0kg (estimate)
Mixed unit input
Input: L=15in, W=38cm, H=1200mm, weight=22lb, qty=8
Output: Values are normalized to display units and shown in summary and breakdown

Formulas

  • Volumetric weight per box (kg) = Volume (cm3) / factor
  • CBM per box (m3) = Volume (cm3) / 1,000,000
  • Chargeable weight (per piece) = sum of max(actual per box, volumetric per box) × quantity
  • Chargeable weight (total) = max(total actual, total volumetric)

FAQ

Factors are different by carrier

You can choose a factor such as 5000 or 6000. Use custom value when your carrier specifies another factor.

Can I mix cm and inch?

Yes. Inputs accept unit suffixes and are converted to your display unit automatically (example: 15in -> 38.1cm).

Multiple box sizes?

Use Add box type to create more rows and calculate all sizes together.

Is pallet count exact?

No, it is an estimate. Actual loading depends on orientation, gaps, protection materials and weight restrictions.

Notice

  • Results are estimates. Factor, rounding, minimum billable weight and calculation mode can differ by carrier and mode.
  • Pallet count varies by loading conditions such as orientation, gaps, box strength, protection and weight limits.
  • Please confirm official quotation and billing rules with your carrier or forwarder.
