Supply Chain Cost Calculator
This calculator aggregates all components of your supply chain cost into a single total, and expresses it as a cost per unit and as a percentage of revenue. Understanding your total supply chain cost is the first step toward identifying where to focus cost reduction efforts. Enter each cost component for the period, along with total units handled and total revenue, to get a complete picture.
Supply chain cost formulas
Total Supply Chain Cost = Procurement + Inbound Transport + Outbound Transport + Warehousing + Inventory Carrying + Other
Supply Chain Cost per Unit = Total Supply Chain Cost / Units Handled
Supply Chain Cost (% of Revenue) = Total Supply Chain Cost / Revenue x 100
Logistics Cost = Total Supply Chain Cost - Procurement Cost
Supply chain cost benchmarking
- Logistics costs (transport, warehousing, inventory) typically represent 5-10% of revenue for efficient supply chains; above 15% warrants investigation.
- Inbound and outbound transportation are often the largest logistics cost components and offer the most immediate savings through carrier negotiation and route optimization.
- Track supply chain cost per unit over time to see whether improvements are actually reducing your per-unit cost.
- Compare procurement cost as a percentage of total supply chain cost: if procurement dominates, cost reduction efforts should focus on supplier negotiations and sourcing strategy.
- Use supply chain cost breakdowns to identify which category to target first for cost reduction projects.
Supply chain cost: frequently asked questions
What is included in total supply chain cost?
Total supply chain cost includes procurement costs (purchase price of goods, supplier management), inbound transportation (freight from supplier to warehouse), outbound transportation (shipping to customers), warehousing and handling, inventory carrying costs, customs and duties for international supply chains, and supply chain management overhead.
What is supply chain cost as a percentage of revenue?
Supply chain costs as a percentage of revenue vary widely by industry. Retail and consumer goods companies typically see 5-15%; manufacturing 10-20%; pharmaceutical 5-10%. Higher-value goods generally have lower supply chain cost percentages than lower-value, high-volume goods.
What is the difference between COGS and supply chain cost?
Cost of goods sold (COGS) includes the direct cost of producing or purchasing products. Total supply chain cost is broader: it includes COGS plus all logistics, warehousing, transportation, and inventory management costs. Supply chain cost analysis helps identify cost reduction opportunities beyond product cost.
How do I reduce supply chain costs?
Key levers include consolidating shipments, optimizing warehouse locations, negotiating better freight rates, reducing inventory through better demand forecasting, near-shoring to reduce lead times and transit costs, and implementing vendor-managed inventory agreements with key suppliers.
What is supply chain cost per unit?
Supply chain cost per unit divides total supply chain cost by the number of units processed through the supply chain in the period. It is a useful metric for benchmarking across SKUs, comparing suppliers, and evaluating the impact of supply chain improvements on unit economics.
