Gaming calculators

Quick calculators for the numbers gamers actually care about — your K/D and KDA, converting mouse sensitivity between games so your aim carries over, your win rate and what it takes to climb, weapon DPS with time-to-kill, and the real odds behind those brutal loot drops. Type in the stats and skip the spreadsheet.
Calculate weapon DPS from damage per hit and fire rate, plus time-to-kill against a target's health pool to compare guns and builds.
Convert your mouse sensitivity between FPS games so your cm/360 stays identical, with presets for popular titles and a custom counts constant.
Work out your kill-to-death ratio from kills and deaths, plus optional kills per game, with a clean result when you finish deathless.
Calculate your KDA — kills plus assists divided by deaths — the standard performance score in MOBAs, with a clean result for deathless games.
Find your real odds of getting at least one drop across many attempts from a per-try drop rate, plus the tries needed for 50%, 90%, and 99% chances.
Calculate your win rate from wins and total games, and find how many games in a row you'd need to win to reach a target win percentage.
Frequently asked questions
Do these work for any game?
The math is the same everywhere. K/D, KDA, win rate, and DPS don't care which title you play — only the numbers change. The sensitivity converter has presets for a few popular shooters plus a custom option for anything else.
Why is my 1% loot drop taking forever?
Because each pull is independent. A 1% rate doesn't guarantee a drop in 100 tries — it works out to about a 63% chance. The loot drop calculator shows exactly how many attempts you'd need for 50%, 90%, or 99% odds.
Is a higher K/D always better?
Roughly, but it isn't the whole story. K/D above 1.0 means more kills than deaths, but in objective or team modes assists and win rate can matter more. That's why we split out KDA for MOBA-style games.
