Helpful Tips
This calculator uses a weighted mean. This means a 5-star review carries 5 times more weight than a 1-star review toward the final score.
Most top-tier products aim for an average of 4.2 to 4.5 stars. Ratings that are “too perfect” (5.0) can sometimes look less trustworthy to savvy shoppers.
A 4.5-star rating with 1,000 reviews is generally considered much more “stable” and reliable than a 5-star rating with only 2 reviews.
To raise your average quickly, focus on resolving the issues mentioned in 1-star and 2-star reviews, as these pull your average down the most.
