KDA Ratio Calculator

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.
