1. What is Performance Rating?

Performance rating is a quantitative measure that evaluates an individual's or system's performance based on weighted criteria. It provides a standardized way to assess performance across multiple dimensions.

2. How Does the Calculator Work?

The calculator uses the weighted average formula:

Where:

• \( Weights \) — Importance of each criterion
• \( Scores \) — Performance score for each criterion (0-100)
• \( Total\ Weight \) — Sum of all weights

Explanation: Each criterion's score is multiplied by its weight, these products are summed, and then divided by the total weight to get the overall rating.

3. Importance of Performance Rating

Details: Performance ratings are crucial for objective evaluations in employee assessments, product comparisons, service quality measurements, and decision-making processes.

4. Using the Calculator

Tips:

1. Add criteria using the "Add Criterion" button
2. For each criterion, enter its weight (relative importance) and score (0-100)
3. Remove unnecessary criteria with the "Remove" button
4. Click "Calculate" to get the weighted performance rating

5. Frequently Asked Questions (FAQ)

Q1: How should weights be determined?
A: Weights should reflect the relative importance of each criterion. They can be determined through expert judgment, statistical analysis, or organizational priorities.

Q2: What's a good performance rating?
A: This depends on your scoring scale. Typically, 80+ is good, 90+ is excellent, and below 60 may indicate poor performance.

Q3: Can I use percentages for weights?
A: Yes, but the calculator works with any weight system as long as you're consistent. The total weight doesn't need to sum to 100.

Q4: How many criteria should I include?
A: Typically 5-10 key criteria. Too few may not capture all aspects, while too many can dilute important factors.

Q5: Can I save my criteria for future use?
A: This basic calculator doesn't save data. For repeated use, consider noting your criteria weights separately.
