While I don't know of any specific calculators. All you need to know is past variables, which are all available, and just plug them into a regular calculator. I just hope you are not trying to use this to gauge the future as it will be completely inaccurate.
No, I'm trying to make a legitimate claim for more Bitcoin against Cloudhashing. How the hell can I calculate this easily? No mining calculator that I know of accepts external data , you can just provide an entry point and from there they "estimate" the future. I don't want an estimation, I want a calculation of the past
