Weighted Score Calculation in Excel

Objective

To calculate a weighted score based on different types of scores assigned different weightings.

Formula Structure

The general formula for calculating a weighted score can be expressed as:

Weighted Score = (Score1 * Weight1 + Score2 * Weight2 + ... + ScoreN * WeightN) / (Weight1 + Weight2 + ... + WeightN)

Excel Formula

In Excel, assuming you have scores in cells A1, B1, C1, etc., and their respective weights in A2, B2, C2, etc., the formula for calculating the weighted score would be:

= (A1 * A2 + B1 * B2 + C1 * C2) / (A2 + B2 + C2)

Example Scenario

Consider the following data:

• Score for Assessment 1 (A1): 80
• Weight for Assessment 1 (A2): 0.3
• Score for Assessment 2 (B1): 90
• Weight for Assessment 2 (B2): 0.5
• Score for Assessment 3 (C1): 70
• Weight for Assessment 3 (C2): 0.2

Implementation

1. Enter Scores and Weights:

   • Cell A1 = 80 (Score1)
   • Cell A2 = 0.3 (Weight1)
   • Cell B1 = 90 (Score2)
   • Cell B2 = 0.5 (Weight2)
   • Cell C1 = 70 (Score3)
   • Cell C2 = 0.2 (Weight3)

2. Formula Implementation: In any empty cell (e.g., D1), input the following formula:

   = (A1 * A2 + B1 * B2 + C1 * C2) / (A2 + B2 + C2)

Result Calculation

• Step-by-step calculation:
  • Weighted Scores:
    • Assessment 1: 80 * 0.3 = 24
    • Assessment 2: 90 * 0.5 = 45
    • Assessment 3: 70 * 0.2 = 14
  • Total Weighted Score = 24 + 45 + 14 = 83
  • Total Weights = 0.3 + 0.5 + 0.2 = 1.0
  • Weighted Score = 83 / 1.0 = 83

Conclusion

This method enables the calculation of a weighted score based on individual scores and their corresponding weights, allowing for a more nuanced evaluation by attributing more significance to certain assessments.
