Google Play Rating Calculator: How Many App Reviews Do You Need?

It depends on your current rating, your existing review count, your target rating, and the average rating of the new reviews you expect. Enter those four numbers into the calculator above for an instant estimate.

Not exactly. Google Play weights current app-version quality more heavily than a simple lifetime average, and — since 2024 — ratings can be shown per-country and per-device. This calculator estimates a simple weighted-average outcome as a planning tool, not a simulation of Google Play's live algorithm.

Enter your current rating and review count above, set the target field to 4.5, and set the expected new-review average to 5.0 — the calculator returns the estimated number of additional reviews needed for your specific numbers.

Check whether it violates Google Play's Developer Program Policies — see Remove Google Play Reviews for what actually qualifies. If it doesn't qualify for removal, use this calculator to model how many new positive reviews would offset its impact instead.
