How it works

The formula

Exactly what this calculator does with your numbers — no hidden assumptions.

01view_in_ar

CBM

CBM = length × width × height in meters (cm ÷ 100). A 50 × 40 × 30 cm carton is 0.06 CBM; 100 cartons are 6 CBM.

02directions_boat

Sea LCL

Less-than-container shipments are charged per “weight or measure”: 1 CBM or 1,000 kg, whichever is greater.

03flight

Air freight

Air chargeable weight is the greater of actual weight and volume (cm³) ÷ 6,000.

FAQ

Questions, answered

Q1How many CBM fit in a container?
Nominal volumes are about 33 CBM (20ft), 67 CBM (40ft) and 76 CBM (40ft High Cube), but in practice you can load roughly 25–28, 55–58 and 65–68 CBM because of carton shapes and gaps. We use the usable figures.
Q2When is a full container (FCL) cheaper than LCL?
Often somewhere around 13–15 CBM for a 20ft container, but it depends on the route and current rates. Ask your forwarder to quote both.
Q3Does weight limit containers too?
Yes — heavy goods can hit the container’s weight limit before it is full. Check the maximum payload with your forwarder.

Estimates only. Usable container capacity depends on carton sizes and stacking; freight forwarders may use different divisors and rounding.
