# User:Chee/Droprates

Well hello! This page is all about figuring out your chances of receiving an item by a specific killcount. There are instructions below on how to determine this.

The chance of receiving any one item in particular by a certain killcount can be determined as:

${\displaystyle 100\left(1-\left({\frac {droprate-1}{droprate}}\right)^{killcount}\right)}$

For example, the chance of receiving a Dragon Warhammer from a single drop is ${\displaystyle {\frac {1}{5000}}}$, meaning 5000 will be used as the droprate

${\displaystyle 100\left(1-\left({\frac {4999}{5000}}\right)^{killcount}\right)}$

This table shows the chance of receiving a ${\displaystyle {\frac {1}{5000}}}$ drop by a certain killcount:
