How is League of Legends KDA calculated?

KDA is (Kills + Assists) divided by Deaths. For example, 8 kills, 2 deaths, and 12 assists gives (8 + 12) / 2 = 10.00.

What happens if I had zero deaths?

Dividing by zero has no defined result, so this calculator (and most in-game trackers) shows Perfect KDA instead of an error whenever Deaths is 0.

What is a good KDA in League of Legends?

Roughly: below 2.0 is below average, 2.0 to 3.0 is average, 3.0 to 4.0 is good, 4.0 to 6.0 is great, and above 6.0 is excellent. These bands are a common community rule of thumb, not an official Riot metric, and expectations shift by role, rank, and game length.

Does KDA account for objectives or gold earned?

No. KDA only counts kills, deaths, and assists. It ignores CS, gold, objective damage, and vision score, so a high KDA does not always mean the best overall performance.

Why do supports and junglers often have higher KDA than laners?

Assists count the same as kills in the formula, and supports and junglers tend to be present for more teamfights without always landing the killing blow, which inflates their assist count relative to solo laners.

Summary

Enter your kills, deaths, and assists to get your League of Legends KDA ratio and a rating from below average to perfect.

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.
