At CNFANS, efficient shipping is a cornerstone of customer satisfaction. One of the most powerful, data-driven methods to optimize your delivery process is by analyzing your own historical shipment records. This guide will walk you through the process of identifying and sorting carriers based on their actual delivery performance in your spreadsheet.
Why Analyze Historical Courier Data?
While advertised transit times are useful, your own historical data reveals the real-world performance
- Make informed decisions for future shipments.
- Set accurate customer delivery expectations.
- Identify consistently reliable or underperforming partners.
- Optimize costs by aligning service speed with actual need.
Step-by-Step: Sorting Carriers by Delivery Time
Assuming your tracking spreadsheet contains columns for Courier Name, Ship Date, and Delivery Date, follow these steps.
Step 1: Calculate Actual Transit Time
First, create a new column titled "Transit Time (Days)". Use a formula to calculate the business or calendar days between the shipment and delivery dates.
Example Excel/Google Sheets formula (using calendar days):
=DAYS([Delivery Date], [Ship Date])
Step 2: Aggregate Data for Each Courier
Create a separate summary table or use Pivot Tables to analyze performance by courier.
- Essential Metrics:Average (Mean) Transit TimeMedian Transit Time
- Consistency Metrics:Standard DeviationRange (Min-Max)
- On-Time Rate:
Step 3: Sort and Identify the Fastest
Sort your summary table by the AverageMedian Transit Time

Your sorted list will provide a clear, evidence-based ranking of couriers from fastest to slowest for your specific shipping profile.
Example Analysis & Best Practices
Sample Summary Table (Sorted)
| Courier | Avg. Transit (Days) | Median Transit (Days) | Std Deviation | Rank (by Median) |
|---|---|---|---|---|
| Courier A | 4.2 | 4 | 0.8 | 1 (Fastest) |
| Courier C | 5.1 | 5 | 1.2 | 2 |
| Courier B | 6.3 | 6 | 3.5 | 3 (Less Consistent) |
