Work Out Your Kill/Death Ratio
Enter your total kills and deaths and get your exact K/D ratio back instantly — no spreadsheet, no mental maths, just the one number you actually want to see.
K/D Ratio Calculator
Your kill/death ratio, the kills needed to reach a target, and how many deaths you can afford on the way.
Result
Formula
K/D = kills ÷ deaths kills needed = (target × deaths) − kills deaths spare = (kills ÷ target) − deaths
Example: 1,200 kills and 1,000 deaths is a 1.20 K/D. Reaching 1.50 without dying again takes 300 more kills.
A ratio built on thousands of matches barely moves. If the number you need looks impossible, it probably is — set a target for this season instead of for the account.
//- 01 - HOW IT WORKS
HOW IT WORKS
- Add up your totals. Take the kills and deaths from whatever you want to measure — a single session, a ranked season, or your whole career so far. Your end-of-match scoreboards and your own match notes are the honest source here.
- Type both numbers in. Put your total kills in one box and your total deaths in the other, exactly as they stand.
- Get your ratio. The tool divides your kills by your deaths and shows the result. If your deaths happen to be zero, don’t invent one — just enter your numbers as they are and let the tool do the division for you.

//- 02 - HOW TO READ YOUR RESULT
HOW TO READ YOUR RESULT
- 1.00 is break-even. A K/D of exactly 1.00 means you average one kill for every death across the matches you counted.
- Above 1.00, you are winning more gunfights than you are losing across that sample. Below 1.00, the reverse is true.
- Sample size changes everything. A ratio built from two good evenings can swing wildly; the same calculation over a full season is a far steadier picture of your play.
- K/D is only one lens. It says nothing about plants, defuses, drones, callouts or support work — read it alongside your win rate, not instead of it.

//- 03 - WHEN TO USE THIS CALCULATOR
WHEN TO USE THIS CALCULATOR
Run it at the end of a session when you want the night summed up in one figure instead of a feeling. Run it across a longer stretch — a month, a season — when a feeling needs testing: players who swear their aim has fallen off are often surprised by what the totals actually say. It is also the cleanest way to judge a change you have made. Give a new role, a new sensitivity or a new operator pool a few weeks of matches, then compare the K/D from before the change with the K/D after it, over similar-sized samples. One evening proves nothing; the same number, tracked honestly over time, starts to mean something.

//- 04 - A WORKED EXAMPLE
A WORKED EXAMPLE
Example (illustrative). Across one evening you log 46 kills and 40 deaths. The calculator divides 46 by 40 and gives you 1.15 — a good night, comfortably above break-even. Now set that beside a full season entered the same way: 512 kills and 488 deaths works out at roughly 1.05. Both numbers came out of the same tool, but they do not carry the same weight. The 1.15 rests on a handful of matches and could be produced by two strong games against weaker lobbies; the 1.05 rests on hundreds of fights and is much harder to argue with. The example is the lesson: same player, same maths, and the bigger sample is the one to believe when they disagree.

//- 05 - COMMON MISTAKES
COMMON MISTAKES
- Mixing samples. Kills from ranked and deaths from all modes, or kills from this season and deaths from last — the ratio of two different sets of matches describes neither of them.
- Judging yourself on one match. A single game can hand you a 4.00 or a 0.25. Neither is your K/D in any useful sense; the figure only settles once the matches behind it pile up.
- Entering the wrong numbers. Rounds won, score and damage are not kills and deaths. Ten seconds checking the scoreboard columns beats a precise ratio built on the wrong pair of figures.
- Rounding the inputs. ‘About 500 kills’ is fine for a rough idea, but a ratio quoted to two decimal places deserves exact totals — round inputs produce a result that looks more certain than it is.
- Comparing across roles. An entry player’s deaths buy space for the whole team; an anchor’s kills come from fights the entry started. Comparing their ratios as if the jobs were identical misreads both.

//- 06 - GOOD TO KNOW
GOOD TO KNOW
This calculator is only ever as accurate as the two numbers you type into it. It does not connect to your Ubisoft account and it cannot fetch your stats for you — everything comes from your own match history and scoreboards, entered by hand. If a total was guessed, rounded or taken from a different set of matches than the other one, the ratio will quietly be wrong, so it is worth taking ten seconds to pull the real figures before you run the calculation.

//- 07 - FREQUENTLY ASKED QUESTIONS
Straight answers
Using the Calculator
Does the calculator pull my stats from Ubisoft automatically?
No. Nothing is fetched from your account or from any live feed — you enter your kills and deaths yourself, and the tool simply does the division on the numbers you gave it.
Where do I find my kills and deaths?
Your end-of-match scoreboards are the most reliable source, backed up by whatever totals your own records keep. The two figures have to come from the same set of matches — kills from one sample and deaths from another produce a ratio that describes neither.
Should I count one match or a whole season?
Either works, but they answer different questions. One session tells you how tonight went; a season’s worth of matches gives you the stable figure. The more matches behind the numbers, the less one bad game can distort the result.
What if my deaths happen to be zero?
Enter your numbers exactly as they stand — don’t invent a death to make the maths tidier. Just remember what a zero-death sample really is: a very small one. A flawless evening is a good story, but it is not a ratio you can plan around until far more matches sit behind it.
Can I use this for one game mode only?
Yes, and that is often the cleaner read. Enter only your ranked totals, or only your casual totals, and the ratio describes that mode instead of blending two very different kinds of matches into a figure that matches neither.
Reading Your Ratio
What K/D counts as good in Siege?
There is no official benchmark, and it depends heavily on your role. A K/D above 1.00 means you win more fights than you lose over that sample; an entry player and a hard support are doing very different jobs, so compare your ratio against your own past numbers rather than anyone else’s.
Why is my ratio here different from the one shown in game?
Almost always because the two figures are counting different things — a different mode, a different period, or a different set of matches. The calculator works on exactly the totals you typed in; the moment the sample behind it matches the sample in game, the figures line up.
Does a high K/D mean I am playing well?
It means you are winning more gunfights than you lose across that sample — nothing more. It says nothing about plants, defuses, droning, callouts or the support work that wins rounds without a kill. Read it alongside your win rate, not instead of it.
How often should I recalculate my K/D?
Whenever a decent block of new matches has piled up — the end of a session for a snapshot, or after a few weeks when you want the steadier picture. Recalculating after every match mostly measures noise, because a single game can swing a small sample wildly.
Can I compare my K/D with a teammate's?
You can put the two numbers side by side, but read them with the jobs in mind. An entry player’s deaths buy space for the team; an anchor’s kills come from fights the entry started. Similar samples, same mode, and roles acknowledged — then the comparison says something. Without those, it mostly measures who plays the riskier role.
