The customer has 12 pallets and wants the cheapest way across. Quote LCL when the volume has crossed the break-even and you leave money on the table; quote FCL too early and you lose the booking. The line between the two moves with the rates, so it is worth checking every time instead of trusting a rule of thumb.
Enter the volume and the rates and the calculator picks the cheaper option.
CargoEZ stores your LCL and FCL rate cards and compares modes on the quote as you build it, so the cheaper option is obvious in seconds. Built for freight forwarders.
How LCL and FCL are priced
The two modes charge on completely different logic, which is why the cheaper one flips as the shipment grows.
LCL cost = W/M × LCL rate + fixed charges
where W/M = the higher of volume (CBM) and weight (tonnes)
FCL cost = containers needed × flat rate per container
LCL, less than container load, is consolidated with other shippers’ cargo and billed on the weight or measure, the larger of the cubic meters and the tonnes. On top of the per-unit rate sit fixed charges for origin and destination handling and the bill of lading, which is why small LCL shipments carry a surprising amount of fixed cost. FCL, full container load, is a flat price for the whole box whether it is half empty or packed tight.
The break-even, and why it moves
Because LCL scales with volume and FCL is flat, there is a volume where they cross. Below it LCL wins, above it a 20ft FCL is cheaper even if it ships half empty. The calculator solves for that point: the fixed cost of the 20ft minus the LCL fixed charges, divided by the LCL rate.
That number is not fixed at 15 CBM like the old rule of thumb says. On a lane with cheap FCL and expensive LCL, FCL can win from 8 or 9 CBM. On a lane with the opposite, LCL stays cheaper past 20. Rate volatility on the ocean has made this swing a lot, so the break-even is worth recomputing whenever rates change rather than quoting from memory.
When the cheaper number is not the answer
The calculator compares price, and price usually decides, but not always. FCL moves faster because it skips consolidation and deconsolidation at both ends, and it handles cleaner for fragile or high-value cargo that you would rather not have stacked with strangers’ freight. If transit time or damage risk matters more than a few hundred dollars, the slightly pricier FCL can still be the right call.
For the volume figure that feeds this comparison, use the CBM calculator, and for how the cargo fits once you go FCL, the container load calculator. More tools are in the freight forwarding calculators section.
