Manually tracking and scoring seller performance is time-consuming and prone to errors. By leveraging built-in spreadsheet formulas, you can create a dynamic, auto-calculating dashboard that assesses sellers based on reliabilityrefund ratios. This guide will walk you through the core logic.
The Core Performance Metrics
We will build a score out of 100, weighted between two critical metrics:
- Reliability Score (Weight: 70%):(Successful Orders / Total Orders) * 100.
- Refund Ratio Score (Weight: 30%):MAX(0, 100 - (Refunded Orders / Total Orders) * 1000). This penalizes refunds heavily, as even a 10% refund rate zeroes this score.
Building the Automated Spreadsheet
Assume your data is structured with the seller name in Column A, and raw data in subsequent columns.
Step 1: Organize Your Raw Data
| Seller (A) | Total Orders (B) | Successful (C) | Refunded (D) |
|---|---|---|---|
| Seller_A | 150 | 142 | 8 |
| Seller_B | 89 | 86 | 3 |
Step 2: Calculate Component Scores
Add columns for calculated metrics:
- Column E: Reliability Score
=(C2 / B2) * 100 - Column F: Refund Ratio Score
=MAX(0, 100 - (D2 / B2) * 1000)
Step 3: Calculate the Final Weighted Score
Column G: Overall Performance Score (out of 100)
=(E2 * 0.70) + (F2 * 0.30)
Step 4: Add a Rating Category (Optional)
Column H: Automatic Rating Tier
Use a nested IFIFS=IF(G2 >= 90, "Excellent", IF(G2 >= 80, "Good", IF(G2 >= 70, "Fair", "Needs Review")))
Complete Formula View for Row 2
| Column | Purpose | Formula (for Row 2) | Sample Result (Seller_A) |
|---|---|---|---|
| E | Reliability % | =(C2/B2)*100 |
94.7 |
| F | Refund Score | =MAX(0,100-(D2/B2)*1000) |
46.7 |
| G | Final Score | =(E2*0.7)+(F2*0.3) |
80.3 |
| H | Rating Tier | =IF(G2>=90,"Excellent",IF(G2>=80,"Good",IF(G2>=70,"Fair","Needs Review"))) |
