The calculator uses a straightforward weighted-average formula based on your current rating and total number of reviews. It gives you a close estimate of how many new 5-star reviews you’d need to reach a specific rating. Real-world results may vary slightly due to rounding, platform-specific display rules, or new reviews coming in with different star values
To give you the clearest benchmark. Using 5-star reviews shows the minimum number required to shift your rating upward. Mixed reviews (4★, 3★, etc.) can still raise your score, but they require more volume and are harder to predict consistently
A perfect 5.0 rating is extremely difficult to achieve unless every existing review is already 5★. When your target rating is 5.0, the formula’s denominator becomes zero, meaning you’d theoretically need an unlimited number of new 5-star reviews to reach it. The only way to truly hit 5.0 is if no lower-rated reviews exist.
If you’re starting from scratch, just one 5-star review instantly gives you a 5.0 average. For any lower target (for example, 4.5), the calculation still allows you to reach it with a single review that meets or exceeds that rating. As more reviews come in, the average will stabilize and the calculator becomes even more useful.
Yes. New reviews with ratings below 5★ will change the average differently and require more total reviews to reach your target. That’s why the tool focuses on the ideal scenario using exclusively 5-star inputs.
We recommend reviewing your numbers regularly, especially after running email flows, loyalty campaigns, or major marketing pushes. Monitoring frequently helps you understand how your review strategy is performing.
Your Google star rating is one of the first signals customers see. A higher rating increases trust, boosts click-through rates in search results, and makes shoppers more likely to choose you over competitors. Even small improvements can lead to meaningful gains in visibility and conversions.
You can view both directly on your Google Business Profile. Simply search for your business name on Google, and your listing will display your average star rating and total number of reviews. You can also check the Google Business dashboard for the most accurate breakdown.
Removing reviews only helps if those reviews truly violate Google’s policies and get approved for removal. Outside of that, your rating won’t change unless new reviews come in. The most effective way to improve your score is to consistently collect more authentic 5-star feedback from satisfied customers.
