How are Google review ratings calculated?
Google averages all your 5-star ratings. Each new review shifts your average slightly. This calculator uses the average formula to determine how many 5-star reviews (which pull your average up to 5.0) are needed to reach your target.
Why do I need so many reviews?
The more reviews you have, the more stable your rating. One negative review hurts less with 100 reviews than with 10 reviews. More reviews also boost your local search ranking.
Can negative reviews hurt my rating?
Yes. This calculator assumes all new reviews are 5-stars. In reality, some will be lower. Aim higher than your target rating to account for this.
