How this calculator works
The kill/death ratio is kills divided by deaths. A ratio of 2 means two kills for every death. The KDA form adds assists to the kills before dividing, so the same player can have a different KD and KDA. Assists are counted differently from game to game: some titles credit an assist only for damage, others for healing or crowd control, and some cap the number of players who share a kill. The calculator uses the numbers you enter and does not apply a game-specific rule.
Formula
KD = kills / deaths. KDA = (kills + assists) / deaths. To find the kills needed for a target ratio with a fixed death count: kills = target KD x deaths. To find the deaths allowed for a target ratio with a fixed kill count: deaths = kills / target KD. A death count of zero has no ratio, because division by zero is undefined.
Worked example
A player with 120 kills, 40 deaths and 30 assists has a kill/death ratio of 120 / 40 = 3.000 and a KDA of (120 + 30) / 40 = 3.750. To reach a ratio of 4 with 40 deaths, the player needs 4 x 40 = 160 kills, which is 40 more than the current total. To keep a ratio of 3 with 120 kills, at most 120 / 3 = 40 deaths are allowed.

Frequently asked questions
Why do I get an error when I enter zero deaths?
Division by zero is undefined, not infinity that you can compare with other sessions. Some games display the kill total or an infinity symbol when a player has no deaths, but that is a display convention. Enter a completed session with at least one death, or compare kill totals instead.
What is the difference between KD and KDA?
KD counts only kills and deaths. KDA adds assists to the numerator, so a support player with few kills and many assists can have a high KDA and a low KD. Use the figure your game shows in its own scoreboard before comparing players.
Does a high KD mean a good player?
Not on its own. A player who avoids fights can keep a high ratio while contributing little, and an objective-focused player may trade kills for a win. KD ignores damage, healing, objectives, map control and the strength of the opponents. Treat it as one number among several.
Do assists count the same in every game?
No. Games differ in how much damage or support is needed to earn an assist, whether a kill is shared, and whether assists appear in the scoreboard at all. The formula here is arithmetic, not a rule set for a particular title. Check the game documentation if the score matters.
Can a KD ratio be below 1?
Yes. More deaths than kills gives a ratio below 1, which is common. A ratio of 0 means no kills at all. Ratios above 1 mean more kills than deaths, and the figure can be very large when the death count is small.
