Understanding the Rating Formula
The calculator uses a weighted average method.
Not all ratings have equal value. A 5-star review contributes more to the overall score than a 1-star review.
Formula for Weighted Score
The weighted score is calculated as:
Weighted Score=(5×Five)+(4×Four)+(3×Three)+(2×Two)+(1×One)
Where:
- Five = Number of 5-star ratings
- Four = Number of 4-star ratings
- Three = Number of 3-star ratings
- Two = Number of 2-star ratings
- One = Number of 1-star ratings
Formula for Total Ratings
The total number of reviews is:
Total Ratings=Five+Four+Three+Two+One
Formula for Average Rating
Average rating is calculated by dividing the weighted score by the total ratings.
Average Rating=Total RatingsWeighted Score
Formula for Rating Percentage
To convert the rating into a percentage:
Rating Percentage=5Average Rating×100
Example Calculation
Let’s see how the calculator works.
Review Data
| Rating | Number of Reviews |
|---|---|
| 5 Star | 120 |
| 4 Star | 50 |
| 3 Star | 20 |
| 2 Star | 7 |
| 1 Star | 3 |
Step 1: Calculate Weighted Score
Weighted Score:
(120 × 5) + (50 × 4) + (20 × 3) + (7 × 2) + (3 × 1)
= 600 + 200 + 60 + 14 + 3
= 877
Step 2: Calculate Total Ratings
120 + 50 + 20 + 7 + 3
= 200
Step 3: Calculate Average Rating
877 ÷ 200
= 4.39
Average Rating = 4.39 / 5
Step 4: Calculate Rating Percentage
(4.39 ÷ 5) × 100
= 87.8%
Rating Percentage = 87.8%
