Kill to Death ratio (often referred to as KDR) is simply the number of kills one has, divided by the number of deaths. League of Legends does not explicitly track this information, but it can easily be calculated manually.


For DPS champions, such as Assassins or Carries, it is one of the most effective ways to evaluate a player's performance. Players with these types of characters should be achieving a KDR greater than 1. In addition, new and lesser informed players generally believe that higher KDR indicate better players.

Other types of champions, such as Pushers, Tanks, and Support characters do not emphasize a high KDR as a factor of a successful game, but take other factors into consideration. Supports and Tanks should have many more assists, and minimal deaths. Pushers should be evaluated by the amount of towers they've pushed down.

In a game, comparing the KDR of both teams as a whole is useful as a rough guide of how well both teams are doing but does not determine a winning team; often the team with more pushing power will come out victorious.

A player may be described as having a "negative" KDR. This is a misnomer, as a negative KDR is impossible, but means that their KDR is less than 1, implying that the player did poorly due to lack of skill.


  • If Player 1 Ratio is 6 / 2 = 3.0.
  • If Player 2 scores a 2:6:8, the K/D-Ratio is 2 / 6 = 0.33.
  • If Player 3 scores a 4:2:17, the K/D-Ratio is 4 / 2 = 2.0.

Keep in mind that assists play an important role that can not be seen by just calculating the K/D-Ratio. For example, Player 3 arguably did a better job than Player 1, though he has a lower K/D-Ratio.

Another type of scoring is dominance factor (DF) , shows even more domination is simple. Kills count as 2, deaths count as -3, and assists are 1. This may seem slightly confusing at first but let's look at the examples from above.

  • If Player 1 scores a 6:2:5, the DF would be 11.
  • If Player 2 scores a 2:6:8, the DF would be -6.
  • If Player 3 scores a 4:2:17. the DF would be 19.

As you can see this accounts all aspects and can give you a more accurate reading. This also gives more opportunity to those who play supports.
