Using this calculator you can get the average cost to upgrade your Mythic weapon to a target level. The values this script uses are based on a simulation of 100,000 crate pulls.
The displayed values can be slightly higher (about 5%) in reality.

I have released the simulator this calculator is based on on Github. Feel free to do whatever you want with it.
