Choosing between a full container (FCL) and shared consolidated space (LCL) comes down to one number: your shipment volume relative to the break-even point. This tool totals the real all-in cost of each option for the volume you actually need to move and tells you which is cheaper — and by how much.
How it works
FCL is a fixed price for the whole box, so its effective cost per CBM falls as you load more cargo. LCL is a flat rate per cubic metre, so its total rises linearly with volume. The break-even is where the two lines cross:
fcl_per_cbm = fcl_all_in / usable_capacity_cbm
lcl_total = lcl_rate_per_cbm × shipment_cbm
fcl_total = fcl_all_in (one container, fixed)
break_even = fcl_all_in / lcl_rate_per_cbm (CBM)
Below the break-even CBM, paying LCL per cubic metre is cheaper than buying a whole container. Above it, the fixed container price is spread over enough cargo to beat the per-CBM rate.
Example and tips
Suppose a 40ft container is quoted all-in at 2400 with 58 CBM usable, and LCL runs 60 per CBM. The break-even is 2400 / 60 = 40 CBM. A 30 CBM shipment costs 1800 by LCL versus 2400 by FCL, so LCL wins. A 45 CBM shipment costs 2700 by LCL but still only 2400 by FCL, so FCL wins. As a rule of thumb, once you exceed roughly two thirds of a container’s usable capacity, FCL is usually the better deal — and it removes the destination deconsolidation step entirely.
