How to Apply Data Formulas for QC, Cost, and Delivery Insights
Tracking order performance manually is time-consuming and prone to error. By leveraging a MyCNBox data spreadsheetQC speed, cost efficiency, and delivery accuracy. This guide walks you through the fundamental calculations.
1. Measuring QC Inspection Speed
This metric helps evaluate the throughput of your quality control process. Faster QC can accelerate overall fulfillment.
Formula & Calculation:
QC Speed (Minutes per Item) = Total QC Time / Number of Items Inspected
Example: If a batch of 50 items took 150 minutes for QC:
Cell A1: 150 (Total QC Time in minutes)
Cell B1: 50 (Number of Items)
Cell C1: =A1/B1
Result: 3 minutes/itemAnalysis Tip:
2. Calculating Cost Efficiency Per Order
Understand your true landed cost versus the item price to assess profitability and shipping cost ratios.
Key Formulas:
- Total Landed Cost = Item Cost + Shipping Fee + Service Fee
- Cost Efficiency Ratio = (Item Value / Total Landed Cost) * 100
Example Order Data:
Cell A2: 45.00 (Item Cost)
Cell B2: 12.50 (Shipping Fee)
Cell C2: 5.00 (Service Fee)
Cell D2: 75.00 (Item Sale Price)
Cell E2 (Total Cost): =SUM(A2:C2) // Result: 62.50
Cell F2 (Efficiency %): =(D2/E2)*100 // Result: 120%Analysis Tip:
3. Quantifying Delivery Accuracy & On-Time Performance
Measure reliability by comparing Estimated Delivery Date (EDD)Actual Delivery Date (ADD).
Formulas & Dashboard:
- On-Time Delivery (Binary Check):
- Average Delay Days:(Array Formula)
- On-Time Rate (Percentage):
Sample Data Columns:
Order # | EDD (C) | ADD (D) | Status (E)
In Cell E2 (for first order):
=IF(D2<=C2, "On Time", "Delayed")
To calculate overall On-Time Rate (assuming 100 orders):
=(COUNTIF(E2:E101, "On Time") / 100) * 100Analysis Tip:
Putting It All Together
By integrating these calculations into your MyCNBox spreadsheet, you create a dynamic dashboard for order efficiency. Start with these basic formulas:
- QC Speed
- Cost Efficiency Ratio
- Delivery Accuracy Rate
- Cost Efficiency Ratio
