Supply Chain Management (SCM) 101: Transportation Management Transportation Costs Fixed vs Variable Fuel Labor Accessorial Charges

What This Is

Transportation costs are a significant component of supply chain expenses, accounting for up to 10% of a company's total revenue. These costs can be broken down into fixed and variable components, including fuel, labor, and accessorial charges. For instance, Amazon's transportation costs are estimated to be around $15 billion annually, making it essential for the company to optimize its logistics network.

Key Frameworks & Formulas

• Transportation Cost: The total cost of moving goods from one location to another, including fuel, labor, and accessorial charges.
• Fixed Transportation Cost: A constant cost associated with transportation, such as insurance and equipment maintenance.
• Variable Transportation Cost: A cost that varies with the volume of goods transported, such as fuel and labor.
• Fuel Surcharge: An additional charge imposed by carriers to account for fluctuations in fuel prices.
• Accessorial Charges: Additional fees for services such as liftgate, inside delivery, and residential delivery.
• Transportation Mode: The method of transportation used, such as truckload, less-than-truckload, intermodal, or air freight.
• Transportation Service Level: The level of service provided by a transportation provider, including on-time delivery and damage-free delivery.
• Transportation Cost Formula: TC = (FC + VTC * Q) / Q, where TC is total transportation cost, FC is fixed transportation cost, VTC is variable transportation cost, and Q is the quantity of goods transported.
• Economies of Scale: The cost savings achieved by increasing the volume of goods transported, which can lead to lower transportation costs per unit.
• Transportation Network Design: The process of designing an optimal transportation network to minimize costs and maximize service levels.

Step-by-Step Application

1. Calculate Transportation Costs: Determine the fixed and variable transportation costs for a given shipment, including fuel, labor, and accessorial charges.
2. Optimize Transportation Mode: Choose the most cost-effective transportation mode based on the shipment's characteristics, such as weight, volume, and destination.
3. Negotiate with Carriers: Negotiate with carriers to secure the best possible rates and services, including fuel surcharges and accessorial charges.
4. Implement Transportation Management System: Implement a transportation management system to streamline transportation operations, track shipments, and optimize routes.
5. Monitor and Analyze Transportation Performance: Monitor and analyze transportation performance metrics, such as on-time delivery and damage-free delivery, to identify areas for improvement.

Common Mistakes

• Mistake: Failing to account for accessorial charges in transportation costs.
• Correction: Include accessorial charges in the total transportation cost calculation to ensure accurate budgeting and forecasting.
• Mistake: Assuming that transportation costs are fixed and cannot be optimized.
• Correction: Continuously monitor and analyze transportation costs to identify opportunities for cost savings and process improvements.
• Mistake: Failing to negotiate with carriers to secure the best possible rates and services.
• Correction: Regularly negotiate with carriers to secure the best possible rates and services, including fuel surcharges and accessorial charges.

Exam / Certification Tips

• Tricky Distinction: Understand the difference between fixed and variable transportation costs, and how they impact transportation cost calculations.
• Common Question Pattern: Be prepared to calculate transportation costs and optimize transportation modes for a given shipment.
• Incoterms Responsibility: Understand the Incoterms rules and how they impact transportation costs and responsibilities.

Quick Practice Problem

A company is shipping 1000 units of goods from a warehouse in Los Angeles to a customer in New York. The fixed transportation cost is $500, and the variable transportation cost is $1.50 per unit. What is the total transportation cost?

Answer: $1,500 (1000 units x $1.50 per unit + $500 fixed cost)

Explanation: The total transportation cost is calculated by adding the fixed cost to the variable cost multiplied by the quantity of goods transported.

Last-Minute Cram Sheet

• Transportation cost = (fixed cost + variable cost x quantity) / quantity
• Fixed transportation cost: constant cost associated with transportation
• Variable transportation cost: cost that varies with the volume of goods transported
• Fuel surcharge: additional charge imposed by carriers to account for fluctuations in fuel prices
• Accessorial charges: additional fees for services such as liftgate, inside delivery, and residential delivery
• Transportation mode: method of transportation used, such as truckload, less-than-truckload, intermodal, or air freight
• Transportation service level: level of service provided by a transportation provider, including on-time delivery and damage-free delivery
• Economies of scale: cost savings achieved by increasing the volume of goods transported
