How to Use the Review Rating Recovery Calculator
Knowing how many new reviews it takes to lift a lowered rating to your target helps you plan a review campaign realistically. This calculator uses current rating and review count, your target rating, and the expected rating of new reviews to compute how many additional reviews you need.
Average rating is the sum of all accumulated reviews divided by count, so products with a larger existing review base need more new reviews to move the average. For the expected new review rating, use a realistic figure based on actual improvements rather than assuming a flat 5.0.
If the expected new review rating is equal to or lower than your target, the calculation is impossible — you'll need to either lower your target or improve product/service quality to raise the rating new reviews are likely to give.
Frequently Asked Questions
As review count grows, each new review has less impact on the average. Products with more existing reviews need more new reviews to move the average.
If the expected new review rating is equal to or lower than your target, no number of reviews will reach the target. Lower your target or improve the quality behind new reviews first.
