1. What is the Star Rating Calculation?

The Star Rating calculation converts a score relative to its maximum possible value into a 5-star rating system. This is commonly used in reviews, ratings, and performance evaluations.

2. How Does the Calculator Work?

The calculator uses the star rating formula:

Where:

• \( Sum \) — The actual score or sum achieved
• \( Max \) — The maximum possible score or sum

Explanation: The formula calculates what percentage of the maximum score was achieved, then scales it to a 5-star system.

3. Importance of Star Rating Calculation

Details: Star ratings provide a quick, visual representation of performance or quality that is easily understood by users across different platforms and applications.

4. Using the Calculator

Tips: Enter the actual score in the Sum field and the maximum possible score in the Max field. Both values must be positive numbers, with Max greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What if my sum is greater than the maximum?
A: The calculator will still work and return a rating higher than 5 stars, which may indicate an error in your input values.

Q2: Can I use decimal values?
A: Yes, the calculator accepts decimal values for both sum and maximum score.

Q3: How is the result rounded?
A: The result is rounded to two decimal places for precision.

Q4: What are common applications of this calculation?
A: This calculation is commonly used in product reviews, app ratings, service evaluations, and performance scoring systems.

Q5: Can I use this for weighted scoring systems?
A: This formula works for simple proportional ratings. For weighted systems, you may need to adjust your sum calculation before using this formula.
