KD Ratio Calculator
A 20 kill, 10 death game gives you a 2.00 KD ratio. This KD ratio calculator turns your kills, deaths, and optional assists into the two numbers most shooters and battle royale players track after every match, the plain kill death ratio and the fuller kill death assist ratio. Enter your kill count and death count, add assists if your game tracks them, and the tool returns both ratios rounded to two decimal places so you can compare a single match, a full session, or a season average against your own history or a squadmate's stats.
Quick answer
KD ratio equals kills divided by deaths, so a 15 kill, 5 death game is a 3.00 KD.

What this tells you
- •KD ratio equals kills divided by deaths, so a 15 kill, 5 death game is a 3.00 KD.
- •KDA ratio adds assists to kills before dividing by deaths, giving credit for damage and setup that did not end in a kill.
- •Zero deaths cannot be divided by, so the tool follows the standard gaming-UI rule and shows your raw kill count (or kills plus assists for KDA) instead of an error.
- •A KD ratio above 1.00 means you are averaging more kills than deaths across the games counted.
- •The tool rounds displayed ratios to two decimals, which matches the precision shown on most in-game scoreboards.
- •You can enter stats from one match, a stack of matches, or a full season, the formula treats every input the same way.
How to Use
- 11. Enter your total kills in the Kills field. This can be from one match or a combined total across many matches.
- 22. Enter your total deaths in the Deaths field, using the same time span as your kill count.
- 33. Optionally enter your total assists in the Assists field if your game tracks them. Leave it blank or at 0 if you only want the plain KD ratio.
- 44. Read the KD ratio as your primary result and check the KDA ratio underneath for the assist-adjusted figure.
- 55. If your death count is 0, the tool shows your raw kill total instead of dividing by zero, matching how most game scoreboards display a perfect no-death record.
How It Works
Formula
KD ratio = kills / deaths, KDA ratio = (kills + assists) / deathsKD ratio divides total kills by total deaths. KDA ratio adds assists to kills first, then divides by deaths, which credits you for helping secure a kill even when you did not land the final hit. True division by zero is mathematically undefined, so when deaths equals 0 this calculator follows the convention used by most game scoreboards and displays the raw kill count for KD (and kills plus assists for KDA) rather than showing an error or an infinite value. Both ratios are rounded to two decimal places for display, while the underlying value keeps full precision for any further comparison you want to make.
Calculation note: values are processed in the order shown above, using the current input units.
Worked Examples
Standard match with deaths
20 kills divided by 10 deaths gives a KD ratio of 2.00. Adding the 5 assists to the 20 kills gives 25, and 25 divided by 10 deaths gives a KDA ratio of 2.50, showing the assist bump above the plain KD figure.
Uneven ratio that does not round cleanly
17 divided by 6 is 2.8333, which the tool rounds to 2.83 for display. Adding 4 assists to 17 kills gives 21, and 21 divided by 6 deaths gives an even 3.50 KDA.
A flawless, no-death game
With 0 deaths, true division is undefined, so the tool applies the standard gaming-UI convention and returns the raw kill count for KD. For KDA it returns kills plus assists, which is 12 plus 3, giving 15.00.
A rough game with more deaths than kills
4 kills divided by 9 deaths gives 0.44, a ratio below 1.00 that signals more deaths than kills. Adding 2 assists to 4 kills gives 6, and 6 divided by 9 deaths gives 0.67 for KDA, still a modest improvement from the assist credit.
KD Ratio Quick Reference
Common kill and death combinations and the KD ratio each one produces.
| Kills | Deaths | KD Ratio | Rating |
|---|---|---|---|
| 5 | 10 | 0.50 | Below average |
| 10 | 10 | 1.00 | Even |
| 15 | 10 | 1.50 | Above average |
| 20 | 10 | 2.00 | Strong |
| 30 | 10 | 3.00 | Excellent |
| 10 | 0 | 10.00 | Flawless (raw kill count) |
Ratings are general community benchmarks, not an official standard, and typical values vary widely by game genre and skill bracket.
Why KDA matters alongside KD
KD ratio is the simplest way to summarize a player's aggression and survivability, but it only counts the kill you personally finished. It says nothing about the damage you dealt to soften an enemy for a teammate or the cover fire that let someone else get the last hit.
KDA ratio fixes that gap by folding assists into the numerator alongside kills. In team-based shooters and battle royale games, a high assist count often means a player is playing support well, tagging enemies, calling out positions, and setting up kills without necessarily getting the final blow themselves.
Neither ratio on its own tells the full story. A player who racks up kills by avoiding fights and picking off weakened enemies late in a match can post a high KD while contributing less to actual team fights than a player with a lower KD but a much higher assist count. Looking at both numbers side by side, which is what this calculator returns, gives a more complete read on in-match contribution than either figure alone.
Common mistakes
- Comparing KD ratios across different game modes. A KD of 1.50 in a slower tactical shooter is not directly comparable to a KD of 1.50 in a fast-paced arcade shooter with respawns.
- Treating a single match as a reliable stat. One good or bad game can swing a small sample size dramatically, session or season totals give a steadier picture.
- Ignoring assists entirely when a game rewards team play. Support-focused players can have a modest KD but a strong KDA that better reflects their impact.
- Assuming a KD below 1.00 always means poor play. Objective-focused roles, like planting bombs or capturing points, often trade kills for match-winning actions that KD does not capture.
- Forgetting that a 0-death game is a special case. Some scoreboards show an infinity symbol for 0 deaths, this calculator instead shows the raw kill count, which is the more common and more readable convention.
