Stuck at 4.0 on Google?
Here's exactly what it takes to move up.
A business displaying 4.0 with 100 reviews needs 6 more consecutive 5-star reviews to display 4.1, and 18 to reach 4.2. These aren't estimates — they're computed from how Google actually rounds ratings, and the full table below covers every review count from 25 to 1,000.
A 4.0 rating is solidly good — and stuck in the most crowded band on Google, where "good" fails to differentiate you from the three competitors displaying the same number. The commercial target from here is 4.5: it's where "good" becomes "excellent," and it's a common cutoff for map-pack filters and "top rated" lists.
5-star reviews needed from a 4.0 rating
Assumes your true average is exactly 4.0. Rows are your current review total; columns are the rating you want Google to display.
| Reviews today | → 4.1 | → 4.2 | → 4.5 | → 4.7 | → 4.8 | → 5.0 |
|---|---|---|---|---|---|---|
| 25 | 2 | 5 | 21 | 47 | 75 | 475 |
| 50 | 3 | 9 | 41 | 93 | 150 | 950 |
| 100 | 6 | 18 | 82 | 186 | 300 | 1,900 |
| 250 | 14 | 45 | 205 | 465 | 750 | 4,750 |
| 500 | 27 | 89 | 410 | 929 | 1,500 | 9,500 |
| 1,000 | 53 | 177 | 819 | 1,858 | 3,000 | 19,000 |
"Consecutive" means 5-star reviews with no new lower ratings in between — mixed incoming reviews raise the count.
Why "4.0" doesn't tell you where you actually stand
Google rounds your true average to one decimal, so a displayed 4.0 covers every average from 3.95 up to (but not including) 4.05. Two businesses both showing 4.0 can be in completely different positions: one a couple of 5-star reviews from displaying 4.1, the other dozens away.
That's also why ratings feel "stuck": new 5-star reviews move your true average invisibly inside the window until it crosses 4.05 — then the displayed number jumps a full tenth at once. The calculator uses your per-star counts to tell you exactly where in the window you are.
How fragile is a 4.0? One 1-star review, by review count
| Reviews today | Displayed after one new 1★ | Damage |
|---|---|---|
| 25 | 3.9 | −0.1 |
| 50 | 3.9 | −0.1 |
| 100 | 4.0 | none |
| 250 | 4.0 | none |
| 500 | 4.0 | none |
| 1,000 | 4.0 | none |
Review volume is armour: the same bad review that knocks a small business down a tenth (or more) does nothing to a business with hundreds of reviews.

Calculate my exact numberFrequently asked questions
How many 5-star reviews do I need to go from 4.0 to 4.1 on Google?
It depends on how many reviews you already have, because every existing review anchors your average. If your true average is exactly 4.0, you need about 2 consecutive 5-star reviews at 25 total reviews, 6 at 100 reviews, and 27 at 500 reviews to display 4.1. Your real distribution shifts these numbers — the free calculator gives you your exact count.
Why is my Google rating stuck at 4.0 even after getting new 5-star reviews?
Google rounds your true average to one decimal place, so 4.0 covers every average from 3.95 up to (but not including) 4.05. If you sit near the bottom of that window, new 5-star reviews are moving your average without yet crossing the rounding threshold — you may be a handful of reviews from ticking over, or dozens, and the displayed number won't tell you which.
Can one bad review drop a 4.0 Google rating?
Yes, if your review count is small. At 25 reviews, a single new 1-star review takes a 4.0 average down to a displayed 3.9. At 100 reviews the same review no longer moves the displayed number — review volume is what protects your rating.
