How the Calculator Works

The Formula

The calculator determines the total sum of your current review scores (current rating × current number of reviews). Then it calculates how many additional 5-star reviews are needed to increase this sum enough to achieve your desired average rating.


                                    (currentRating × currentReviews) + (5 × newReviews) = desiredRating × (currentReviews + newReviews)

Key Points

The result is always rounded up to ensure you meet your target
Your desired rating must be higher than your current rating
All new reviews are assumed to be 5-star reviews
The calculation doesn't account for any potential negative reviews you might receive

Important Note

This calculator provides estimates based on the assumption that all new reviews will be 5-star reviews. In reality, you may receive some lower-rated reviews, so aim to collect more than the calculated number to account for this.
