KD Ratio Calculator
This calculator turns kills, deaths and assists into a K/D ratio, a KDA ratio and a per match line, and tells you what share of your fights you came out of alive. The second mode is the one worth having: give it a target K/D and the rate you are actually playing at now, and it solves for the deaths and kills it will take to get there, using d = (T x D - K) / (F - T). It is honest about the two cases people trip over, a target you have already passed and a target above the rate you are playing at, which never arrives at all. Assists count as full kills in the KDA, which is the usual convention but not every game's.
