FAQ
Frequently asked questions
How does the calculator work?
It uses Google’s rating formula to estimate how many new 5-star reviews are needed to reach your desired average.
Why does it take so many reviews to move my rating?
If you’ve had lower ratings in the past, they still affect your average. The more reviews you also have, the more 5-star ones you’ll need to shift the score.
Is 5 or 4.9 a good rating to aim for?
Absolutely. Most people trust businesses with a 4.7 or above. A 5 or 4.9 signals a consistently high standard and builds strong trust.
Does this work for other platforms?
No—this calculator is designed for Google’s rating system only. Other platforms, like Yelp or Facebook, use different formulas.
