KDA Ratio Calculator

Compute your kill/death/assist ratio

How it is calculated

The ratio is KDA = (kills + assists) ÷ deaths. All three inputs are plain counts from one match or from a longer stretch such as a whole season, and the result is a single number rounded to two decimals. If deaths is 0 the tool divides by 1 instead, so a game with no deaths simply returns kills + assists (7 kills and 5 assists with no deaths give 12.00). Negative values are rejected. Kills and assists carry the same weight, so one assist counts as much as one kill, which suits some games and roles better than others.

Worked example

In a match you get 12 kills, 5 deaths and 9 assists. Add kills and assists: 12 + 9 = 21. Divide by deaths: 21 ÷ 5 = 4.20. A plain kill/death ratio would be 12 ÷ 5 = 2.40, so the 9 assists lift the figure by 1.80. To see the effect of dying less, change deaths to 4 and the KDA becomes 21 ÷ 4 = 5.25.

Common mistakes

  • Using a plain kills ÷ deaths calculation and calling it KDA. KDA adds the assists to the top, so leaving them out understates the number for support-style play.
  • Believing that zero deaths gives an infinite or error result. This tool treats 0 deaths as 1, so the score is just kills plus assists.
  • Averaging per-match KDA values. A short game with 0 deaths can dominate the average; add up kills, assists and deaths across the matches first and then divide once.
  • Comparing KDA across different roles or games without context. Because assists count as much as kills, supports and carries will naturally land at different levels.

About this calculator

This calculator computes KDA = (Kills + Assists) / Deaths, a standard performance metric in multiplayer online battle arena and shooter games that rewards both securing kills and supporting teammates while penalizing dying, unlike a plain kill/death ratio that ignores assists entirely. A KDA above 3.0 is generally considered strong in games like League of Legends and Dota 2, though the exact benchmark varies by role — supports naturally rack up more assists than kills, while carries are judged more on raw kill contribution.

Competitive players track KDA match-to-match to gauge their own performance trend, esports analysts use it alongside other stats to evaluate pro players, and in-game leaderboards and post-match summary screens display it as one of the primary ways to compare performance across a roster.
