How many five star reviews move your rating
Put in the rating you have, the number of reviews behind it and the rating you want. The arithmetic runs in your browser and sends nothing anywhere.
Nothing is uploaded and nothing is stored. Close the tab and the numbers go with it.
Your rating, and what it takes to move it
An average is stubborn in proportion to how many numbers are already in it. This shows exactly how stubborn yours is.

What it takes
29 five star reviews
which lands you at★★★★★4.50
The figure assumes every new review is a five, which is the best case rather than the likely one.
Why the number is larger than people expect
Three properties of an average that decide how a rating behaves, and why the advice to just get more reviews is usually right.
Every review already counted is a vote against change.
A rating over forty reviews moves four times more slowly than the same rating over ten. The denominator is the whole story, and it only ever grows.
The last tenth costs the most.
Climbing from a low four to a mid four is unremarkable. Climbing from a mid four to a high four takes a multiple of it, because each new five star review is closer to the average it is trying to lift.
Rounding is a cliff, and it can fall your way.
Ratings are shown rounded, so one sitting just under a boundary reads worse than the arithmetic says it is. A couple of reviews can be the whole difference, which is worth knowing before you decide the situation is hopeless.

Questions about star ratings
The arithmetic, the rounding and the one thing that is faster than either.
How is the number worked out?
Your rating multiplied by your review count gives the total stars behind it. The tool then adds five star reviews one at a time until the new average reaches the target, which is the same sum done in closed form.
Why does it say a target is impossible?
Because no number of five star reviews can take an average above five. If the target you typed is five and your current rating is lower, the honest answer is that you get arbitrarily close and never arrive.
Can I make an old bad review count for less?
Not directly. How a rating is weighted and shown is the platform's decision and not something a business owner sets. What you do control is how many recent reviews sit next to the old one.
Is there a faster route than collecting reviews?
Only removal, and a platform decides that against its own content policy rather than against whether you liked the review. The reliable route is volume, which is why the ask matters more than the arithmetic.
Does replying change my rating?
No. A reply changes what a reader sees next to the review, not the number above it. It is worth doing for the reader rather than for the average.

More reviews means more to reply to
GetSetReply drafts a reply for each one as it lands, so a rising review count does not turn into a rising evening job.
