The math

How the calculator works

Your rating is the average of every review. To pull it up, each new review has to be above your target. The calculator assumes every new review is 5 stars, so treat the result as the minimum.

It also shows the other side: how far one 1-star review would move you today.

Formula

New 5-star reviews = (target × total − current × total) ÷ (5 − target)

With your numbers
(4.6 × 120 − 4.2 × 120) ÷ 0.4 = 120.0
Rounded up
120 reviews
One 1-star review today would take you to
4.17 stars

Rating levels

What's a good Google rating to aim for?

Under 3.0
Fix the causes first. Read your lowest reviews and reply to each one.
3.0 to 3.9
Work on the common complaints, and ask every customer for a review.
4.0 to 4.6
A solid rating. Keep asking every customer so new reviews keep coming.
4.7 to 5.0
Keep it current. A steady flow of recent reviews matters as much as the number.

Mistakes that can cost you your reviews

  • Asking only happy customers

    Google calls this review gating. Ask every customer, whatever their experience.

  • One link for every location

    Each location has its own review link. The wrong one sends reviews to the wrong place.

  • Copying reviews from other sites

    Never repost Facebook or Yelp reviews on Google.

  • Ignoring negative reviews

    Reply politely and fix the issue. Other shoppers read your replies.

  • Asking everyone at once

    Spread requests over time instead of one big blast.

  • Fake or self-written reviews

    Never write reviews for your own business. Google can suspend your profile.
