Review Velocity Calculator

The review velocity calculator shows you exactly how many new Google reviews per month you need to overtake a competitor's review count and star rating inside a target timeframe. Enter your current reviews and rating, your competitor's reviews and rating, and the number of months you have. The tool returns a required reviews-per-month figure, a projected rating, and a month-by-month catch-up timeline so you can set a realistic outreach pace.

Review velocity (how fast you gain reviews over time) is one of the signals that influences how prospects judge a local business, and a steady pace is easier to sustain than a last-minute scramble. Use this review velocity calculator to turn a vague goal like "get more reviews" into a concrete monthly target your team can act on. The projected rating uses a weighted average, so you can also see whether your incoming five-star reviews will lift you past a higher-rated rival.

Run a few scenarios by adjusting the timeframe or the assumed star rating of new reviews, then copy the summary or download the timeline as a CSV to share with your team. When you are ready to track your map rankings and review growth in one place, you can start free with ProMapRanker.

FAQ

How does the review velocity calculator decide how many reviews I need?

It takes the gap between your competitor's review count and your own, adds one review so you clearly overtake them, then divides that total by your target number of months and rounds up to a whole number per month.

How is the projected rating calculated?

The tool blends your existing reviews and rating with the new reviews you plan to collect using a weighted average. By default it assumes new reviews come in at five stars, but you can change that assumed star value to model a more conservative outcome.

Is my data sent anywhere?

No. Every calculation runs entirely in your browser using plain arithmetic. Nothing you type is uploaded, stored, or shared, so you can model competitor scenarios privately.
