Drop Rate Calculator

The percentile tells you what fraction of players would have received at least one drop by your kill count. A 90th percentile means 90% of players would have the drop — you're in the unlucky 10%.

The chance of 0 drops is the raw probability of going your entire kill count without a single drop. The math is (1 - 1/rate)^kills.

The median is the 50th percentile — the kill count where half of players would have the drop. For a 1/512 drop, the median is about 355 kills (not 512, because of how probability compounds).
