K/D ratio calculator

How to use the K/D ratio calculator

This calculator divides your kills by your deaths to give your K/D, adds assists to give your KDA, and works out how many more kills you need to reach a target K/D. Every result updates as you type. Nothing is saved, so refreshing the page puts the fields back to their defaults.

Step by step

1. Type your totals into Kills and Deaths. The defaults are 20 and 15.
2. If you also want KDA, fill in Assists (optional). Leave it at 0 if you only care about K/D.
3. Read K/D ratio and KDA. Both are rounded to two decimal places.
4. Under Reach a target K/D, enter the ratio you want in Target K/D (default 2). The box below shows Kills needed (no more deaths).

Reading the results

• Perfect appears when deaths are 0 and you have at least one kill. You cannot divide by zero, so there is no number to show. The kills-needed box shows a dash in this case.
• Already there means your current K/D already meets or beats the target.
• The kills-needed figure assumes you do not die again. It is the target multiplied by your deaths, minus the kills you already have, rounded up to a whole kill.

Worked examples

With the defaults, 20 kills and 15 deaths give 20 ÷ 15 = 1.33. With 0 assists, the KDA is also 1.33. Add 9 assists and the KDA becomes (20 + 9) ÷ 15 = 29 ÷ 15 = 1.93.

For a target of 2.00, you need 2 × 15 = 30 kills in total. You have 20, so the tool shows 10.

In real games you will keep dying, so here is a more realistic way to plan. Enter the deaths you expect to have at the end, not the deaths you have now. Say you are at 20 kills and 15 deaths, you want 1.50, and you expect about 10 more deaths. Enter 25 deaths and a target of 1.5. The tool needs 1.5 × 25 = 37.5, rounds up to 38 total kills, and shows 18 more. Check: 38 ÷ 25 = 1.52, while 37 ÷ 25 = 1.48 falls short.

Lifetime stats move slowly. At 1,000 kills and 1,000 deaths (1.00), a strong 20 and 10 match only lifts you to 1,020 ÷ 1,010 = 1.01. Reaching 1.10 without another death would take 100 more kills.

K/D and KDA formulas differ between games

K/D is always kills divided by deaths. KDA is less consistent, so check what your game or stat site uses before you compare numbers.

• Assists at full value: this tool calculates KDA as (kills + assists) ÷ deaths. The League of Legends Wiki defines KDA the same way.
• Assists at half value: some trackers count each assist as half a kill. For example, Destiny Tracker lists Destiny 2 KDA as (kills + assists ÷ 2) ÷ deaths. To get that version here, type half your assists into the Assists box. With 20 kills, 10 assists and 15 deaths, the half-assist KDA is (20 + 5) ÷ 15 = 1.67. The full-assist version is 30 ÷ 15 = 2.00.
• Zero deaths: the League of Legends Wiki notes that a deathless game is either treated as 1 death or shown as a perfect score. This tool shows "Perfect". To match a site that divides by 1, enter 1 death.

Many games also show K/D/A as a scoreline such as 12/3/8. That is three separate counts in the order kills, deaths, assists, not a ratio.

Tips and common mistakes

• Swapping fields. Scoreboards list kills, deaths, assists in that order. Entering assists as deaths gives a very different answer.
• Trusting the rounding. A K/D shown as 2.00 can sit just under 2. For example, 399 ÷ 200 = 1.995, which rounds to 2.00, so a target of 2 still asks for 1 more kill.
• Comparing across games. A KDA from a game that counts full assists is not comparable with one that counts half, even at the same kill and death totals.
• Looking past the ratio. K/D says nothing about objectives or wins. For match results, the win rate calculator tracks the other half of the picture.
