Understanding Star Rating Calculations
Learn the mathematics behind rating improvements and platform-specific algorithms
The Basic Formula
Star ratings use a weighted average formula:
Average Rating = (Sum of all ratings) ÷ (Total number of ratings)• 10 reviews at 5 stars = 50 points
• 5 reviews at 4 stars = 20 points
• 3 reviews at 3 stars = 9 points
Total: 79 points ÷ 18 reviews = 4.39 stars
The Mathematics of Improvement
Let's say you have a 3.5-star rating from 100 reviews. To reach 4.0 stars:
Current total points: 3.5 × 100 = 350 points
Target total points: 4.0 × (100 + X) = 400 + 4X
Equation: 350 + 5X = 400 + 4X
Solution: X = 50 five-star reviews needed
Platform Differences
Google Business Profile
Uses standard weighted average, rounds to nearest tenth. Considers review recency and reviewer credibility.
Yelp
Filters ~20% of reviews based on reviewer credibility. Not all reviews count toward displayed rating.
Weights recent reviews more heavily. Uses recommendations alongside star ratings.
