What actually moves a DealerRater Dealer Rating
DealerRater’s public Dealer Rating isn’t a plain average of every star rating a dealership has ever received. Per DealerRater’s own published update to its rating calculation, more recent reviews are weighted more heavily than older ones, with the trailing 24 months mattering most — DealerRater ties this directly to average dealership staff turnover of roughly two years, meaning a rating from a salesperson or service advisor no longer at the store shouldn’t carry the same weight as a recent one.
A dealership also needs a minimum of 5 reviews within that trailing 24-month window before a Dealer Rating is calculated at all. Fall short of that, and the profile shows "Not Yet Rated" instead of a star score — which means a dealership with a thin or stale review history isn’t just under-rated, it may not be showing a rating at all.
- Recency weighting — reviews from the trailing 24 months carry more weight than older ones, reflecting typical staff turnover.
- A 5-review minimum — a dealership needs at least 5 reviews in the past 24 months before any Dealer Rating is calculated; fewer shows as "Not Yet Rated."
- Response rate — factored into the separate PowerScore used for DealerRater’s award programs, not the public star rating itself.
- Guideline compliance — reviews DealerRater removes for violating its Terms of Use or Community Guidelines don’t count toward the rating at all.
