Glassdoor Rating Calculator
Enter your current Glassdoor rating, review count, and target rating to see how many new 5-star employee reviews it takes to get there.
New Glassdoor reviews needed to go from 3.8★ to 4.5★
This platform uses a weighted rating calculation, not a simple average — treat this number as a rough estimate, not an exact target.
Glassdoor's rating isn’t a simple average — treat this as a directional estimate. See how Glassdoor's rating actually works or Glassdoor review management.
What actually moves a Glassdoor rating
Glassdoor calculates a company’s overall rating using a proprietary algorithm applied to all-time approved reviews, and it weights more recent reviews more heavily than older ones. Glassdoor doesn’t publish the exact formula, but it has confirmed the rating isn’t a flat, unweighted mean of every star rating a company has ever received — which is why a burst of very old reviews behaves differently than the same volume of recent ones.
A company needs at least 5 reviews before Glassdoor will display an overall rating and a descriptive label (such as "Excellent" or "Good"); those label cutoffs were themselves set using data percentiles across the reviews Glassdoor has collected. The overall rating figure is rounded to the nearest 0.1 and refreshes on a roughly 7-business-day cycle as new reviews are approved.
- Recency weighting — more recent employee reviews influence the overall rating more than older ones, so a stale review history behaves differently than an actively maintained one.
- A minimum-review threshold — no overall rating or label displays until a company has at least 5 approved reviews.
- Guideline compliance — reviews Glassdoor removes for violating its Community Guidelines (confidential info, harassment, incentivized/coerced content) don’t count toward the rating at all.
- A periodic refresh cycle — the displayed rating updates roughly every 7 business days as new approved reviews come in, rather than instantly with each submission.
- Workplace Factor sub-ratings (culture, senior management, compensation, career opportunities, work/life balance, diversity & inclusion) are collected per review and shown separately, giving candidates a fuller picture beyond the single overall number.
