What is Kill Death Ratio?
Kill Death Ratio (KDR or K/D) is the number of kills divided by deaths in a video game. A KDR of 1.0 means you get one kill for every death. Above 1.0 indicates you eliminate more opponents than you die. Top competitive players often maintain KDRs of 2.0-5.0 depending on the game.
KDR is a common performance metric in FPS games (Call of Duty, Battlefield, CS2), battle royales (Warzone, Apex Legends, Fortnite), and tactical shooters (Valorant, Rainbow Six Siege). While KDR doesn't capture everything (objective play, assists, teamwork), it's a widely recognized skill indicator.
使用される計算公式・方程式
この計算ツールは5つの主要な公式を使用しています：
1 Kill Death Ratio ▼
1500 kills and 1000 deaths: KDR = 1500/1000 = 1.50.
2 Kills Needed for Target KDR ▼
To reach 2.0 KDR with 1000 kills and 800 deaths (no more deaths): Need 2.0 × 800 - 1000 = 600 more kills.
3 KDA Ratio (with Assists) ▼
Including assists gives a more complete picture. 1500 kills + 500 assists / 1000 deaths = 2.0 KDA.

よくある質問 (FAQ)
What is a good KDR? ▼
Average is 1.0 (by definition, total kills = total deaths in a match). Above 1.0 is above average. 1.5+ is good. 2.0+ is very good. 3.0+ is exceptional. Pro players often maintain 3.0-5.0+ depending on the game.
Does KDR matter in competitive gaming? ▼
KDR matters as one indicator, but objective play, teamwork, and game sense often matter more. A player with 0.9 KDR who plays objectives may be more valuable than a 2.0 KDR player who avoids engagements.
What is KDA vs KDR? ▼
KDR counts only kills/deaths. KDA (Kill-Death-Assist) adds assists to kills: KDA = (K+A)/D. KDA better reflects team contribution, especially for support roles that get many assists.
How does SBMM affect KDR? ▼
Skill-Based Matchmaking (SBMM) places you against similar-skill opponents, naturally pushing KDR toward 1.0 over time. Without SBMM, skilled players would have higher KDRs because they face more varied opponents.
Can I reset my KDR? ▼
Most games don't allow KDR resets without creating a new account. Some games offer a 'prestige' or seasonal reset. To improve KDR organically, focus on positioning, map knowledge, and choosing favorable engagements.
