Why Knowing Your Freight Costs Is Critical

Knowing and understanding your freight costs is important for a business for several reasons:

  • Profitability and Cost-Efficiency: Both freight-in and freight-out are a significant part of your business’s expenses if you pay for them. Accurately determining these costs allows you to assess their impact on each shipment’s profitability, ensuring you aren’t losing money on shipping expenses. 
  • Negotiating Better Rates: When you compare rates from different carriers or freight forwarders, you might identify cost-saving opportunities that you can use to negotiate favorable pricing and terms based on your shipping volumes and specific needs. 
  • Avoiding Costly Errors: Unexpected charges can be costly surprises when you don’t understand and know all the possible expenses. 
  • Managing Logistics Better: Knowledge of your freight expenses helps you manage your overall logistics and shipping more effectively. You can optimize inventory acquisition time, stock management, lead times, and delivery timelines. 
  • Optimizing Supply Chain: Understanding and managing your freight costs better can mean optimizing your entire supply chain, from inbound to outbound freight.

Key Components of Ocean Freight Charges

You might want to create an ocean freight charges list to understand your possible expenses better. 

The list should be a comprehensive breakdown of components such as:

  • Base Ocean Freight Rate: This is the core charge for transporting goods between the origin and destination ports. Carriers usually quote the base rate as cost per container for full-container load shipping (FCL) and per ton or per cubic meter for less-than-container load freight (LCL). 
  • Surcharges: Ocean freight typically includes a bunker adjustment factor, fuel surcharge, and security surcharge. The fuel surcharge is added to the base rate to cover fuel cost changes, while the security surcharge applies costs for ensuring cargo safety at the ports and during transit. A peak season surcharge may also apply during high-demand periods like holidays. 
  • Handling Charges: Your shipment attracts handling fees, such as loading and unloading costs along different parts of the chain.
  • Additional Service-Based Costs: Depending on your preference and the ocean freight forwarding service you use, the total cost may include charges for extra or value-added services like pre-shipment inspection, customs clearance fees, inland haulage, cargo insurance, and last-mile delivery.

Factors Influencing Ocean Freight Rates

Ocean freight prices can rise or fall based on several factors. These may include:

  • Demand and Supply Changes: Peak seasons usually experience a high demand for shipping, which results in a space shortage that leads to higher rates. Low demand and excess shipping capacity often lead to lower rates as carriers scramble to sell all their container space. 
  • Carrier Pricing: Carriers have varying base freight rates and additional charges. 
  • Shipping Distance and Route: Freight transportation costs generally increase as the distance between the origin and destination increases. Additionally, some routes or lanes are more expensive due to higher risks, increased demand, or heavy traffic. 
  • Changes in Fuel Costs: Ocean freight rates usually increase when bunker fuel costs increase, as carriers have to offset the increase in their operating costs. 
  • Amount and Type of Cargo: The base freight rate depends on the cargo’s actual weight or volumetric weight in LCL freight. Also, if your cargo requires special handling, such as when shipping dangerous goods like lithium batteries, the charges will be higher. 
  • Weather Conditions: Carriers may experience increased operational costs due to adverse weather conditions like fog, hurricanes, or storms. These extra costs are often passed to shippers and importers.

How to Calculate Ocean Freight Charges

Let’s now discuss freight cost calculation for ocean shipments in greater detail. 

Calculating Ocean Freight Charges Manually 

To calculate ocean freight costs manually, follow the steps below:

1. Determine the Cargo’s Weight and Dimensions for LCL Shipments

For the dimensions, measure the length, width, and height of each package in centimeters. Then, calculate the volume in cubic meters by multiplying the measurements and dividing the result by 1,000. 

Package Volume = (Length x Width x Height) in centimeters ÷ 1,000

Total Cargo Volume = Individual Package Volume x Number of Packages 

If the packages have varying measurements and volumes, add all the volumes of the individual packages to get the total cargo volume. 

You’ll also measure the weight of each package in kilograms. If the packages have the same weight, multiply the figure by the number of packages to obtain the cargo’s total weight. 

If the package weights differ, add them to get the total weight of the cargo. 

Note: For FCL shipments, the carrier will charge per container based on the container size and type (refrigerated or non-refrigerated). You can get this charge directly from the carrier or your freight forwarder.

2. Determine the Chargeable Weight

The chargeable weight is the value that will be used to calculate the base freight cost. It’s either the actual overall weight of the cargo or its overall volumetric weight, whichever is greater. 

Calculate the volumetric weight:

Volumetric Weight = Volume (m³) x The Carrier’s Volume Conversion Factor in kg/m³

For example, assuming the total cargo volume is 30m³, and the carrier’s conversion factor is 200kg/m³, the chargeable weight is:

Volumetric Weight = 30m³ x 200kg/m³ = 6,000 kg

Note: Typically, when the total weight of the cargo exceeds 1,000 kg, the actual weight is used to calculate LCL freight charges. 

3. Research Freight Rates 

With this information, contact different carriers to get their base rate per kg or per cubic meter. 

You should also ask them about additional charges, such as port handling fees and fuel surcharge. 

4. Calculate the Base Freight Charges 

Multiply the chargeable weight by the carrier’s base rate to get the base freight charges:

Base Freight Charges = Chargeable Weight in kg x Carrier’s Base Rate per kg

For example, if your cargo’s total volume is 125m³ and the carrier’s base freight rate is $50 per cubic meter or ton, the base freight cost is 125m³ x $50 = $6,250.

Note: The volume conversion factor for ocean freight is 1,000 kg or 1 ton (1 cubic meter = 1,000 kg). 

5. Calculate the Total Freight Charges

The total freight cost will be the base freight cost plus surcharges and additional costs.

Total Freight Charges = Base Freight Cost + Surcharges + Additional Costs

You can compare and confirm your results with the carrier by asking them directly for a quote.

Ocean Freight Costs Example Calculation

Next, let’s check out a real-world shipping scenario:

An importer wants to ship 50 packages from Canada to the US. The total cargo weight is 5,000 kg, and the volume is 20m³. The carrier’s base freight rate is $4 per kg, and the conversion factor is 200kg/m³. 

Here’s how to calculate the freight cost:

  • Step 1: Volumetric weight = 20m³ x 200kg/m³ = 4,000 kg
  • Step 2: The chargeable weight will be 5,000 kg because the actual gross weight is higher than the volumetric weight. 
  • Step 3: Freight cost = 5,000 kg x $4/kg = $20,000

In this case, the total freight charge will be $20,000, assuming no surcharges or additional costs.

Frequently Asked Questions (FAQs)

Let’s wrap up with answers to questions we often receive about ocean freight charges:

Why Do Ocean Freight Prices Fluctuate So Much?

Ocean freight prices fluctuate so much due to the complex interaction of key factors such as demand and supply, carrier pricing, weather conditions, and fuel cost changes. 

The charges have to be adjusted constantly based on these and other factors to reflect real-world scenarios. 

Are Port Fees Included in Freight Quotes?

When working with a carrier directly, port fees are typically not included in the freight quote because carriers show the cost of the vessel, fuel surcharges, and other expenses related to the actual journey. 

Port fees, such as terminal handling fees, storage fees, and other surcharges, are charged at the ports.

But if you work with Ship4wd, our quotes include port fees. It’s always advisable to double-check the details and scope of the quote to understand what is included or excluded.
