Average star rating calculator
Enter how many reviews you have at each star level. Get your true average, what Google actually displays, and what it takes to move it.
Your real rating vs the one customers see
Google shows one decimal, but underneath it keeps the exact average. That gap matters: a business displaying 4.3 might be a hair from 4.4, or a long climb away. Knowing which one you are changes this month's plan. And the thresholds are not cosmetic: 68% of consumers filter out businesses below 4 stars, and a third will only consider 4.5 and up.
If the calculator says you are close to the next tenth, a short burst of asking happy customers can tip it. Our guide to asking for reviews has the word-for-word scripts, and the template generator writes the messages for you. For the revenue side of every tenth of a star, see the star value calculator.
Frequently asked questions
How does Google calculate my star rating?
It is a straight average of all review scores on your profile, displayed rounded to one decimal place. Google retired its old Bayesian weighting years ago, so every review counts equally regardless of age.
Why does my displayed rating not move when I get new reviews?
Rounding. If your true average is 4.32, new 5-star reviews silently push it toward 4.35, and only when it crosses that boundary does the displayed 4.3 become 4.4. This calculator shows exactly how far you are from the next tick.
Where do I find my review counts per star level?
Open your business on Google Maps and click your star rating. The breakdown panel shows the bar chart of 1 to 5 star counts. Hover or tap each bar for the exact number.
Do deleted or filtered reviews count in the average?
No. Only published reviews count. If Google removes a review for a policy violation, your average recalculates without it, which is why reporting fake reviews is worth the effort.
