If you want to know how a real expert resolve issues and increase clients’ Google ranking, sales, and customers.

You will find on this page 2 Google Reviews Calculators, one for checking your Google Reviews Rating Score and another to see how many reviews you need to achieve a higher rating score.

Google Reviews Star Rating Score Calculator

Google Reviews Star Rating Score is normally the compound average of the ratings received.

In geeky terms, this is the formula for Google Reviews: {\textstyle \sum }(Review Score X Number of Reviews) / Total Number of Reviews. However, check the notes for some nuances.


1 Star X 2 reviews = 2 points + 2 Stars X 2 reviews = 4 points + 3 Stars X 5 reviews = 15 points + 4 Stars X 10 reviews = 40 points + 5 Stars X 20 reviews = 100 points

Total points: 161

161 points / 39 total reviews = 4.1 (only the 1st decimal counts and rounding rules apply)

That’s why I built this calculator to make your job easier:

Google Reviews Improve Rating Score Calculator

Use this calculator to calculate how many 5-star Google reviews your business needs in order to increase your average rating star rating.

Notes for Google Reviews Calculation

It may take as much as 2 weeks for the latest reviews to influence the rating score.

Also, Google may use other signals to ensure that the overall score best reflects the quality of the establishment.

What are the “signals” that Google talks about? No one knows for sure, but professionals speculate these matter:
How many of your ratings have written comments
What is the “feeling” in each comment
How much can Google trust the reviewer
What is your rating score on Facebook, Tripadvisor, Yelp, BBB…
