Analyzing delivery times and shipping fees to make smarter, data-driven logistics choices.
The Core Dilemma: Speed vs. Cost
At FishGoo Shipping, selecting the right freight line—Air or Economy (typically Sea Freight)—is a fundamental business decision. While air freight offers unparalleled speed, economy lines provide significant cost savings. The optimal choice isn't universal; it depends on your specific cargo, timeline, and budget. A systematic comparison using your recorded data is key to unlocking long-term efficiency.
Analyzing Your Spreadsheet Data: A Step-by-Step Guide
Your historical shipping spreadsheet is a goldmine of insights. Here’s how to structure your analysis:
1. Categorize and Clean Your Data
Ensure your spreadsheet has consistent columns: Shipment Date, Service Type (Air/Economy), Origin/Destination, Weight/Volume, Total Shipping Fee, and Actual Delivery Time.
2. Calculate Key Metrics Per Shipment
- Cost per Unit (CPU):
- Average Delivery Time:
- Reliability Variance:
- Average Delivery Time:
3. Perform Route-Specific Comparison
Never compare globally. Analyze data for identical routes (e.g., Shanghai to Los Angeles). Create a simple comparison table:
| Route: Shanghai to LA | Air Line | Economy Line |
|---|---|---|
| Avg. Shipping Fee (100kg) | $1,200 | $400 |
| Avg. Delivery Time | 5 days | 28 days |
| Cost per Day Saved | See calculation below | |
4. Apply the "Cost per Day Saved" Formula
This powerful metric reveals the premium for speed. For a given route:
(Air Freight Cost – Economy Cost) / (Economy Delivery Days – Air Delivery Days) = Cost per Day Saved
Example: ($1,200 - $400) / (28 - 5) = $800 / 23 = ~$34.78 per day saved.
Is gaining 23 days worth $34.78 per day for your business? For perishable "FishGoo" or time-sensitive parts, it might be. For bulk, non-urgent inventory, likely not.
Making Smarter Choices: Beyond the Spreadsheet
Data informs, but context decides. Integrate these factors:
- Product Value & Perishability:
- Inventory Holding Costs:
- Customer Promise:business cost
- Hybrid Strategy:
- Inventory Holding Costs:
Conclusion: Continuous Optimization
Comparing air and economy lines is not a one-time task. Regularly update your FishGoo Shipping spreadsheet with new shipments, track fluctuating freight rates, and reassess your "cost per day saved" threshold. By transforming raw data into actionable intelligence, you empower FishGoo to dynamically choose the most cost-efficient line for every shipment, balancing speed and expense to boost overall supply chain performance.
