Unit Economics in Logistics: A Deep Dive into Last-Mile Delivery Costs

By Research Team 6 min read

Key Takeaways

  • Last-mile delivery accounts for up to 53% of total shipping costs.
  • Route density and drop size are the primary levers for margin expansion.
  • Automation and AI-driven routing are shifting cost structures from variable to fixed.

The logistics sector is undergoing a massive transformation, driven largely by the e-commerce boom and changing consumer expectations for rapid delivery. However, the true battleground for profitability lies in the "last mile"—the final leg of a product's journey from a fulfillment center to the end customer.

The Density Problem

Unlike line-haul logistics, where costs are spread over massive volumes moving between few nodes, last-mile is inherently fragmented. The cost per delivery is highly sensitive to route density (deliveries per square mile). A 10% increase in density can often translate to a 15-20% improvement in unit economics due to reduced fuel consumption and driver time per package.
