The Average Rating Calculator (Star Rating) is a tool designed to help users calculate the average rating based on multiple star categories. Whether you’re analyzing product reviews, customer feedback, or any other rating system, this calculator simplifies the process.
Formula
The formula to calculate the average rating is:
AR = (1 × a + 2 × b + 3 × c + 4 × d + 5 × e) ÷ R
Where:
- a = Number of 1-star ratings
- b = Number of 2-star ratings
- c = Number of 3-star ratings
- d = Number of 4-star ratings
- e = Number of 5-star ratings
- R = Total number of ratings
How to Use
- Enter the number of 1-star ratings into the first field.
- Input the count for 2-star, 3-star, 4-star, and 5-star ratings in their respective fields.
- Click the “Calculate” button.
- The result will display the average star rating based on the input values.
Example
Suppose you have the following ratings:
- 10 users gave 1 star
- 5 users gave 2 stars
- 20 users gave 3 stars
- 15 users gave 4 stars
- 30 users gave 5 stars
The total number of ratings (R) = 10 + 5 + 20 + 15 + 30 = 80
The sum of ratings = (1 × 10) + (2 × 5) + (3 × 20) + (4 × 15) + (5 × 30) = 290
Average Rating (AR) = 290 ÷ 80 = 3.63
