LCL vs FCL calculator

Work out whether this shipment is cheaper as LCL or FCL on your own quoted rates - and the exact volume where the answer flips.

Total for the whole shipment. Work it out on the CBM calculator if you only have carton sizes.

Metric tonnes. LCL is billed on the greater of cbm and tonnes, so add this if the cargo is dense.

Per cbm or revenue ton, as quoted.

CFS handling, deconsolidation, destination THC, docs. This is what LCL quotes leave out.

Flat rate for the container size you would book.

Terminal handling, docs, drayage. Quote both sides to the same delivery point.

What your forwarder will actually load, not the catalogue figure. A 20ft is about 33 cbm published, a 40ft about 67 - plan on 80-90% of that.

Enter your volume and both quoted rates. The break-even volume appears with them.

How this is calculated

Chargeable (LCL) = greater of volume in cbm and gross weight in tonnes
LCL total        = chargeable x LCL rate + LCL other charges

Containers       = volume / usable volume per container, rounded UP
FCL total        = containers x FCL rate + FCL other charges

Break-even cbm   = (FCL rate + FCL other - LCL other) / LCL rate

Assumptions

  • LCL is billed on the revenue ton - the greater of cubic metres and metric tonnes. Leave the weight field blank and the tool bills on volume alone, which will understate a dense shipment.
  • FCL is a step function, not a rate per cbm. Cost is flat inside a container and jumps by a whole container above it, which is why comparing two per-cbm rates gives the wrong break-even.
  • Usable volume per container is an input, not a constant. Published internal volume is a ceiling nobody reaches once cartons, pallets and load plans are real.
  • Both totals are only comparable if both quotes cover the same scope to the same delivery point. LCL quotes routinely exclude CFS handling and deconsolidation.
  • Everything is currency-agnostic. Enter every figure in one currency and read the answer in that currency.

How to use this LCL vs FCL calculator

Enter your shipment volume in cubic metres and, if you know it, the gross weight in tonnes. The weight field is optional but it is the one that changes answers: LCL is billed on the revenue ton, so a dense consignment is charged on tonnes rather than cubic metres, and leaving it blank quietly makes LCL look cheaper than it will invoice.

Then put in both quotes. On the LCL side that is the rate per cubic metre or revenue ton, plus everything else in the other charges field - CFS handling, deconsolidation, destination terminal handling, documentation. On the FCL side it is the flat rate for the container you would book, plus its own fixed charges.

The last field is usable volume per container. This is deliberately not filled in for you, because it is not a constant. Both totals appear immediately with the arithmetic printed underneath, along with the break-even volume where the answer flips.

Worked example

You have 16 cbm of homeware, 4.2 tonnes gross, moving from Ningbo to Rotterdam.

  • LCL quoted at 92.00 per revenue ton, plus 320.00 of CFS and destination charges
  • FCL quoted at 1,750.00 for a 20ft, plus 240.00 of terminal and documentation charges
  • Your forwarder says to plan on 28 cbm usable in that 20ft

Volume is 16 and weight is 4.2, so the chargeable figure is 16 revenue tons - volume wins here.

LCL comes to 16 × 92.00 + 320.00 = 1,792.00.

One container covers 16 cbm, so FCL is 1 × 1,750.00 + 240.00 = 1,990.00.

LCL wins by 198.00. But look at the break-even: (1,750.00 + 240.00 - 320.00) ÷ 92.00 = 18.15 cbm. You are two cubic metres away from the crossover. One more pallet and the container is cheaper - which is exactly the kind of thing a rule of thumb cannot tell you.

The 15 CBM rule, and why it keeps being wrong

Search this question and you will be told the break-even is 15 cbm. Sometimes 13, sometimes 12 to 15. It is the most repeated number in ocean freight and it is a description of one set of rates on one lane at one moment, presented as if it were a constant.

The break-even is a piece of arithmetic with four inputs:

Break-even cbm = (FCL rate + FCL other charges - LCL other charges) / LCL rate per ton

Change any of them and the answer moves. A soft container market drops the FCL rate and pulls the break-even down towards 10. A competitive LCL rate on a heavily consolidated lane pushes it past 20. Heavy destination charges on the LCL side pull it down again. None of that is visible in a rule of thumb, and all of it is on your quotes.

The rule is not useless - it tells you roughly where to start paying attention. Below about 5 cbm nobody quotes a container seriously, and above about 20 cbm it is nearly always worth pricing one. Between those two the rule is guessing and you do not have to.

Why weight decides more of this than people expect

LCL is sold on the revenue ton, written W/M on quotes: weight or measure, whichever is greater. One cubic metre or one metric tonne, and you pay for whichever produces the larger count.

For most consumer goods, volume wins and the distinction never comes up. For anything dense it inverts. Ten cubic metres of ceramic tile at 1.4 tonnes per cubic metre is 14 tonnes, so you are billed for 14 units and not 10 - a forty per cent increase on a figure most people never check, and enough to move the break-even down by several cubic metres.

The catch is that FCL has the mirror-image problem in a form this calculator cannot see: a container has a payload limit as well as a volume limit, and dense cargo can exhaust the weight allowance with the box half empty. If your shipment is heavy for its size, confirm the payload limit before you assume one container is enough.

What LCL quotes leave out

The ocean rate is the part of an LCL bill you see first and the smallest part of what you pay.

At origin there is consolidation handling. At destination there is CFS handling and deconsolidation, terminal handling, documentation, customs clearance and inland delivery. Most of those are charged per cubic metre, which means they grow with your shipment at exactly the point where LCL is already losing its cost advantage.

This is the single most common reason a comparison comes out wrong. A port-to-port LCL rate against a door-to-door container rate is not a comparison, and the difference is usually larger than the freight gap being argued about. Ask both sides to quote to the same delivery point, with the same scope, before putting either number in this calculator.

When the container is not full and still cheaper

Because FCL cost is flat inside a container, there is nothing wasteful about shipping a container that is only three-quarters full if the total still beats LCL. Empty space costs nothing extra. What matters is the total, not the fill.

Where that logic breaks is the second container. Cross a container boundary by two cubic metres and you are paying full price for a box that is almost empty, which is the worst position on the entire cost curve. The usual fixes are to send the balance as LCL alongside one full container, to step up to a larger box, or to hold the overflow for the next shipment.

This calculator flags it whenever the final container comes out below sixty per cent full, because at that point the split option is almost always worth a phone call.

Where price stops being the answer

If the two totals land within about ten per cent of each other, stop optimising the freight and look at everything else.

LCL adds days at both ends for consolidation and deconsolidation, and the delay at destination lands after arrival, when the goods are already expected. It exposes your cargo to more handling and to a container you did not pack or seal, which is why damage and shortage claims are more common on it. It also behaves differently once the container lands - free time, demurrage and detention clocks work differently on a box that is yours versus one that is shared.

A container that costs a hundred more and arrives a week sooner in one piece is not the expensive option.

Frequently asked questions

At what CBM is FCL cheaper than LCL?
There is no fixed figure, which is the whole reason this calculator exists. The number quoted across the industry is somewhere between 10 and 15 cbm, but it is entirely a function of your LCL rate per cbm, your FCL flat rate and the fixed charges bolted onto each. Put your own quotes in and the break-even comes out exact - on a cheap LCL rate it can sit above 20 cbm, and on a soft container rate it can drop below 8.
Is LCL always cheaper than FCL?
No, and assuming so is the most expensive mistake in this decision. LCL charges by the cubic metre, so cost rises in a straight line with volume, while a container is a flat fee no matter how full it is. Past the crossover the flat fee wins and keeps winning, and because LCL destination charges scale with volume too, a large LCL consignment can end up costing more than a container that was never full.
Should I use FCL for 10 CBM?
At 10 cbm you are in the band where it genuinely depends on the quote, so get both priced rather than following a rule. Run the numbers here with your actual rates. If the two totals land within about ten per cent of each other, price has stopped being the deciding factor and transit time, handling risk and how firm your volume estimate is should make the call instead.
Does cargo weight affect the FCL vs LCL decision?
Heavily, and it is the input most comparisons leave out. LCL is billed on the revenue ton, meaning the greater of your cubic metres and your metric tonnes, so a dense shipment is charged on weight while the volume figure still looks small. Ten cbm of tiles weighing 14 tonnes is billed as 14 units, not 10, which drags the break-even down and often makes a container cheaper far earlier than expected.
What is a revenue ton or W/M?
W/M stands for weight or measure, and the revenue ton is whichever of the two is larger for your consignment - one cubic metre or one metric tonne, whichever produces the bigger number. It exists because a carrier sells both space and payload, and a shipment can exhaust either one first. Enter your gross weight in the weight field and this calculator applies the rule for you and says which one you are being billed on.
What charges do LCL quotes leave out?
The ocean rate is usually the smallest part of an LCL bill. What appears later is CFS handling and deconsolidation at destination, terminal handling, documentation, customs clearance and inland delivery - and most of those scale with your volume, so they grow exactly when LCL is already losing its advantage. Put them in the other charges field or the comparison is not a comparison.
How many CBM fit in a 20ft or 40ft container?
A 20ft standard dry container is about 33 cbm and a 40ft standard is about 67 cbm by published internal volume - Ocean Network Express lists 33.1 and 67.6, Evergreen 33.2 and 67.5. Real usable volume is lower, typically 80 to 90 per cent of that once cartons, pallet footprints and a workable load plan are accounted for. Enter the usable figure your forwarder will actually load, not the catalogue number.
How much longer does LCL take than FCL?
Longer at both ends, and the delay is in handling rather than on the water. Your cargo waits to be consolidated with other shippers before it sails, then waits again to be deconsolidated and released at destination. The sailing itself is identical. Plan for extra days rather than extra hours, and remember the release delay lands after arrival, when your customer is already expecting the goods.
