Questions this estimate can answer
- A forwarder quotes ocean freight by weight or measure (W/M).
- Your shipment contains multiple carton, crate or pallet lines.
- You want to audit a quote before comparing the headline ocean rate.
Ocean freight calculator
No W/M knowledge or freight quote required: enter each carton, crate or pallet line and get the chargeable CBM/tonne basis. Add ocean and local prices only when you have them.
Example values included
Ten cartons at 100 × 80 × 80 cm and 42 kg eachCompare LCL chargeable CBM with metric tonnes, apply W/M minimums and expose fixed local charges in one estimate.
W/M units = max(total CBM, gross metric tonnes); total = W/M units × rate + fixed feesEnter the outside size, number and packed weight of each cargo type. We convert the shipment to CBM and tonnes, compare them and calculate W/M automatically. Quote prices are optional.
Planning rule in use: the larger of total CBM or metric tonnes, with a 1 W/M minimum. Open the quote section only if you have prices from a forwarder.

Method & limits
The result uses the formula below. Check the measurements, unit setting, and applicable carrier or supplier rule before using it.
Tariffs can use minimums, density rules, local charges, and currencies that differ from this simple W/M model. Follow the forwarder's quote.

Worked example
ResultVolume controls at 6.4 W/M units in this common model; fixed origin, destination and document fees remain separate.
Avoid these errors
A calculator can expose the arithmetic; the applicable carrier rate card, handling standard, or freight quotation still controls the real transaction.

8 minHow to calculate LCL W/M for multiple cartons, crates, and pallets ↗Build cargo lines, total CBM and gross weight once, and apply weight or measure without double-counting quantity.
8 minLCL minimum charges and local fees: build an all-in estimate ↗Separate W/M charges from shipment-level fees so a small LCL quote does not look cheaper than its invoice.
8 minCBM vs weight ton vs W/M for LCL: do not compare the wrong units ↗Separate physical volume, gross tonnes, chargeable W/M, and quoted rates so an LCL estimate survives invoice review.
