Ocean Freight Calculation Methods: FCL/LCL Billing and Freight Rate Composition

1. FCL (Full Container Load) Freight Calculation

FCL uses a flat rate per container type, charged regardless of how much cargo is loaded inside:

Ocean Freight = Base Rate + Surcharges (BAF + PSS, etc.)

2. LCL (Less than Container Load) Freight Calculation

LCL is charged by Revenue Ton (RT)—whichever is greater, weight or volume:

LCL Freight = Rate × MAX(Weight in tonnes, Volume in CBM)

Example:

Cargo: 2.5 CBM / 1.2 tonnes, Rate: $55/RT
Revenue Ton = MAX(2.5, 1.2) = 2.5 RT
Ocean Freight = $55 × 2.5 = $137.50

3. Spot Rates vs. Contract Rates

Comparison	Spot Rate	Contract Rate
Pricing Method	Real-time quotation per booking	Long-term contract rate (6 months to 1 year)
When market rises	Price increases	Locked in at low rate; unaffected
When market falls	Enjoy low market price	Higher than market (subject to MQC)
Space Guarantee	None (may have no space in peak season)	Yes (contractually guaranteed)
Suitable For	Businesses with unstable cargo volumes	Stable shippers averaging >50 TEU/month
