KDA Ratio
KDA Formula
If Deaths is 0, the ratio is shown as Perfect KDA instead of dividing by zero. Ratings below are a common community rule of thumb, not an official Riot metric.
Summary
KDA (Kills, Deaths, Assists) is the most common shorthand for how much a League of Legends player contributed to fights versus how often they died. The ratio is (Kills + Assists) divided by Deaths, so a jungler with heavy assists can post a strong KDA even with a modest kill count. When Deaths is zero the ratio is undefined by normal division, so the game and most trackers show it as a Perfect KDA instead of an error.
How it works
- Enter Kills, Deaths, and Assists from a single game (or a stretch of games).
- If Deaths is 0, the result shows Perfect KDA instead of dividing by zero.
- Otherwise KDA = (Kills + Assists) / Deaths, rounded to two decimal places.
- The ratio is compared against common community bands to produce a rating.
Use cases
- Check your KDA ratio right after a match without opening the client stats screen.
- Compare KDA across two games to see which role or champion performed better.
- Settle a lobby debate about who actually carried the game.
- Track whether a support or jungler's low kill count is offset by high assists.
- Log a pentakill or deathless game and confirm the Perfect KDA label.
- Estimate KDA for a champion pool by testing a few representative stat lines.
