This platform uses a weighted rating calculation, not a simple average — treat this number as a rough estimate, not an exact target.

Trustpilot's rating isn’t a simple average — treat this as a directional estimate. See how Trustpilot's rating actually works or Trustpilot review management.

What actually moves a TrustScore

Trustpilot’s TrustScore is a Bayesian average, not a plain arithmetic mean of your star ratings. A new business’s score starts weighted toward a small number of neutral phantom reviews, which dilutes as real reviews come in — so a handful of early five-star reviews moves the needle less than the same reviews would once you have a longer track record.

Recency also matters. The most recent reviews carry more weight than older ones, and Trustpilot’s own guidance is that a steady, consistent flow of reviews produces a more stable score than sporadic bursts. A business that stops collecting reviews for months can see its TrustScore behave less predictably even without any new negative feedback.

  • Bayesian averaging — new or low-review businesses are weighted toward a neutral starting point that dilutes as genuine reviews accumulate.
  • Recency weighting — recent reviews influence the score more than older ones.
  • Review consistency — a steady stream of reviews produces a more stable score than infrequent bursts.
  • Guideline compliance — reviews Trustpilot removes for violating its guidelines (fake, incentivized, wrong-business) don’t count toward the score at all.
