What is ACS in VALORANT?
Average Combat Score
ACS is Average Combat Score — your combat score per round, the headline number on the VALORANT scoreboard.
ACS is Average Combat Score, the number the in-game scoreboard sorts by. It is your total combat score divided by rounds played, and combat score itself rewards damage dealt, kills, assists and some non-damage contributions. Because it is per-round rather than per-match, it is comparable between a 13-3 stomp and a game that went to overtime.
What makes ACS more useful than a kill count is that it pays out for damage that did not finish. Dealing 140 to two players who are then killed by a teammate registers, where a K/D reads it as nothing. That makes it a better single-number summary of whether you were doing work in a round, particularly for players who create space rather than take the last shot.
It is not a complete picture, and it is worth knowing where it is weak. ACS rewards fragging over utility, so a Controller who smokes a site perfectly and enables three free kills will read below a Duelist who took them. Comparing ACS across roles will systematically undervalue the players holding the round together.
Rough bands are worth having in your head: around 150 is an average game at most ranks, 200 and above is a strong one, and 250-plus is a game you carried. These are conventions from how the number lands in practice rather than anything Riot publishes, so treat them as orientation rather than a grading scale.
What moves ACS and what does not
Two players finish a 24-round match with 18 kills each. The first took most of theirs as clean opening duels and did little else. The second took hers later in rounds, after putting 150 damage into two other players who were finished by teammates.
Their kill counts are identical and their K/D may be too, but the second player's combat score is materially higher, because the damage that did not finish still scored. This is the case ACS exists to handle.
The reverse also holds. A player who tags four enemies for 40 each and converts none of it still banks score for the damage, which is why ACS rarely reads as zero even in a bad game.
What combat score is actually made of
Combat score is not published as a formula, but its behaviour is consistent enough to describe. Damage is the largest single input, kills add a substantial amount on top, and assists contribute a smaller share. Some non-damage actions register as well, which is why a support agent's score is rarely as low as their kill count would suggest.
The important structural point is that damage counts whether or not it kills. This is what separates ACS from every kill-based statistic and it is why the number rewards the player who consistently opens opponents up for their team.
The MVP badges at the end of a match are decided on ACS. Match MVP is the highest across all ten players and team MVP the highest on the losing side, which is why an MVP badge sometimes goes to someone whose team lost and whose kill count was not the highest on the scoreboard.
Where ACS misleads is across roles, and it does so systematically rather than randomly. Duelists are handed the opening duels and therefore the damage; Controllers spend their round placing smokes that generate kills for other people. Reading a Controller's ACS against a Duelist's is close to meaningless, and reading it against other Controllers is far more informative.
The practical way to use it is as a trend on yourself rather than a comparison against teammates. Your own ACS across twenty games, on the agents you actually play, tells you something real. One game's number against a teammate on a different role tells you almost nothing.
What people get wrong about ACS
Commonly said
ACS is just kills with extra steps.
Actually
Damage that never results in a kill contributes, as do assists and some non-damage actions. Two players with the same kills routinely have very different ACS.
Commonly said
A higher ACS always means the better player.
Actually
It measures fragging, and it under-rewards utility. A Controller whose smokes win a site will usually read below the Duelist who walked through them.
Commonly said
ACS is comparable across matches of any length.
Actually
It is, and that is the point — it is per round rather than per match. Total combat score is not comparable; ACS is.
Where you see it in-game
ACS is the first numeric column on the in-game scoreboard, and the scoreboard sorts by it. It is also what the game uses to decide the MVP badges at the end of a match — both the match MVP and the team MVP are the highest ACS in their scope.
Which stat to use, and when
ACS is the default because it is on the scoreboard, but it is one of four numbers worth knowing and each answers a different question. Picking the right one is most of what separates useful post-game review from arguing.
Use ACS to ask whether you were doing damage. It is the broadest single measure and the only one visible during a match, so it is the right number for a quick read.
Use ADR when you want damage without the kill and assist weighting — it is the more literal reading, and comparing it against your ACS tells you how much of your score came from finishing rather than from chipping.
Use KAST to ask whether you were present. It is the number that catches the player whose four good rounds hide sixteen empty ones, and it is the one that most often changes how a match looks.
Use econ rating to ask whether you spent well. It barely moves on full buys and it is decisive on saves, which are the rounds that determine the economy the rest of the match runs on.
K/D is the one to use least. It ignores damage, ignores trades and ignores the round context entirely, which is why it survives on scoreboards rather than in analysis.
Related terms
KAST
KAST is the percentage of rounds where you got a kill, an assist, survived, or were traded — a measure of consistent contribution rather than fragging.
Econ rating
Econ rating is damage dealt per 1,000 credits spent — how much value you got out of what you bought.
ADR
ADR is average damage per round — total damage dealt divided by rounds played.
Common questions
What does ACS mean in VALORANT?
ACS is Average Combat Score — your combat score per round, the headline number on the VALORANT scoreboard.
What does ACS stand for?
ACS stands for Average Combat Score. ACS is Average Combat Score — your combat score per round, the headline number on the VALORANT scoreboard.
What is a good ACS in VALORANT?
Roughly 150 is an average game at most ranks, 200-plus is strong, and 250-plus is a game you carried. These are practical conventions rather than thresholds Riot publishes.
Is ACS the same as combat score?
No. Combat score is the running total for the match; ACS divides it by rounds played. The average is what makes a short match and a long one comparable.
Where can I see my ACS?
It is the first numeric column on the in-game scoreboard during and after a match. Third-party trackers also show it per match and as an average across many games, which is more useful for spotting a trend than any single result.
How is ACS calculated in VALORANT?
Riot has not published the formula. Its behaviour is consistent though: damage is the largest input, kills add a substantial amount, assists a smaller share, and some non-damage actions register too. The total is then divided by rounds played.
What does ACS stand for?
Average Combat Score. The 'average' matters — it is per round, which is what makes a short match and a long one comparable.
How does ACS work?
What makes ACS more useful than a kill count is that it pays out for damage that did not finish. Dealing 140 to two players who are then killed by a teammate registers, where a K/D reads it as nothing. That makes it a better single-number summary of whether you were doing work in a round, particularly for players who create space rather than take the last shot.
