Frequently Asked Questions
How does the calculator work?
We use a simple formula based on your current number of reviews and average rating to calculate how many perfect 5-star reviews are needed to reach your goal.
Can I go over a 5.0 rating?
No. Google’s review system caps ratings at 5.0, so that is the maximum possible average you can reach.
Why do I need so many 5-star reviews?
The more existing reviews you have, the harder it is to move your average. Our calculator gives you the exact number you need based on your current data.
Does this work for Yelp or Facebook ratings?
This tool is optimized for Google Business reviews but works similarly for other platforms that average ratings out of 5.0.
What if my customers leave 4-star reviews instead?
This calculator assumes new reviews are 5-star only. A mix of ratings will increase the number of reviews needed to hit your goal.
