How is CS2 player rating calculated?

When you see a Counter-Strike player ranked with a "rating" of 1.20 or 0.95, it isn't a single Valve-issued stat — it's a composite score derived from a handful of objective per-round measurements. HLTV's rating (currently Rating 2.1) is the most widely cited, and most stat sites compute their own variants on the same idea.

Kills per round — straightforward, but weighted higher for multi-kills.

Deaths per round — fewer is obviously better.

KAST — the percentage of rounds in which the player got a Kill, Assist, was Survived, or was Traded. Captures contribution beyond raw frags.

Impact — bonus for opening kills, clutches, and rounds where the player's contribution clearly tipped the outcome.

ADR — Average Damage per Round. Damage dealt regardless of whether it secured the kill.

A rating above 1.00 is above average. Top pros typically sit between 1.10 and 1.30 across a season; ratings above 1.40 over a meaningful sample size are exceptional. The top of our players list above will give you the current frame of reference.
