Ocean freight is the transportation of goods via cargo ships across international waters — the backbone of global trade, carrying approximately 90% of world merchandise trade by volume. An ocean freight calculator helps importers, exporters, freight forwarders, and supply chain managers estimate the cost of shipping goods by sea, including all components of ocean freight billing: ocean freight rate (per container or per freight ton for LCL), origin charges (container stuffing, export customs, port handling), destination charges (import customs, port handling, delivery), and surcharges (bunker adjustment factor, peak season surcharge, congestion surcharge, canal surcharges). Ocean freight is offered in two primary modes: FCL (Full Container Load, where the shipper uses the entire container) and LCL (Less than Container Load, where cargo shares space with other shippers and is charged per cubic meter or per metric ton, whichever is greater). The major container sizes are 20' (TEU, approximately 33 CBM usable), 40' standard (approximately 67 CBM), and 40' High Cube (approximately 76 CBM). Ocean freight rates are highly volatile — affected by fuel costs (bunker fuel), port congestion, global demand/supply of vessel capacity, alliances between major shipping lines, and seasonal patterns (Chinese New Year, back-to-school season). The calculator helps determine FCL vs. LCL break-even, total landed cost including all charges, and transit time to estimate pipeline inventory cost.
FCL Cost = Ocean Freight Rate + Origin Charges + Destination Charges + Surcharges LCL Cost = MAX(Volume CBM, Weight Metric Tons) × Rate per CBM/MT + Origin + Destination + Surcharges CBM = (L cm × W cm × H cm) / 1,000,000 FCL Break-Even CBM = FCL All-In Cost / LCL Rate per CBM Pipeline Inventory Cost = In-Transit Value × Transit Days / 365 × Cost of Capital
- 1Determine cargo volume (CBM) and weight (metric tons) — LCL charges the higher of the two.
- 2For FCL, assess which container size (20', 40', 40'HC) fits your cargo volume and weight.
- 3Obtain FCL rate from carrier/freight forwarder: Shanghai-LA 20' container = $X all-in.
- 4Obtain LCL rate per CBM: typically $40–$120/CBM for major Asia-US lanes.
- 5Compare: if cargo volume exceeds 50–60% of a 20' container (16–18 CBM), FCL is usually cheaper.
- 6Add all surcharges: BAF (Bunker Adjustment Factor), PSS (Peak Season Surcharge), GRI (General Rate Increase).
- 7Add origin and destination charges: approximately $300–$600 per container each side.
- 8Calculate pipeline inventory cost for the transit period to include in total landed cost.
A 40'HC container fully loaded to 70 CBM costs $60.50/CBM all-in. At this rate, FCL beats LCL once shipment exceeds approximately 20 CBM (FCL $4,235 / $120 LCL rate = 35 CBM break-even).
LCL cargo at 8.5 CBM costs $1,092 all-in — significantly cheaper than a 20' FCL ($2,500+) for this small shipment. LCL is cost-effective up to 12–15 CBM on most Asia-US lanes.
At $95/CBM LCL rate and $2,500 FCL cost, FCL becomes economical when shipment exceeds 26 CBM (approximately 78% of a 20' container). Shipments below 26 CBM should use LCL to avoid paying for unused container space.
28-day ocean transit means $180K of inventory is 'at sea' for nearly a month. At 10% cost of capital, this represents $1,381 in financing cost — a hidden landed cost that air freight can eliminate (at much higher transport cost).

{'case': 'Overheight/Overwidth Cargo', 'note': "Cargo exceeding standard container interior dimensions (40'HC: 12m L × 2.35m W × 2.69m H) requires flat rack or open top containers at 30–70% premium. Some cargo requires out-of-gauge (OOG) permits, special lashing, and port handling equipment — significantly higher cost and transit time."}. In the Ocean Freight Calc, this scenario requires additional caution when interpreting ocean freight results. The standard formula may not fully account for all factors present in this edge case, and supplementary analysis or expert consultation may be warranted. Professional best practice involves documenting assumptions, running sensitivity analyses, and cross-referencing results with alternative methods when ocean freight calculations fall into non-standard territory.

Track the Shanghai Containerized Freight Index (SCFI) and Freightos Baltic Index (FBX) weekly — these public benchmarks show market rate trends by trade lane. When the SCFI drops 20%+ below your contracted rate, use your contract's 'market adjustment' clause (if negotiated) or delay non-urgent shipments to capture lower spot rates.

The world's largest container ship, MSC Irina, can carry 24,346 TEUs — roughly 122,000 standard shipping containers worth of goods. Loaded end-to-end, the containers on one voyage of MSC Irina would stretch 750 km (466 miles). The shipping industry estimates that if ocean shipping were a country, it would be the world's 6th largest greenhouse gas emitter — driving major investment in LNG, methanol, and ammonia-powered vessels.
