Mining Rig Calculation Spreadsheet

[Ophion]

Hey Everyone

The last couple of days ive spend some time to make a nice spreadsheet.
I made it so i could calculate the profit i would make/day and time till return of investment.
Since i didnt want to keep it for my self:

Greetz & HF Mining,

You show the current revenue as "the important part", but the most important part is future revenue. Your "Time till return of investment" is only valid if it is less than 10 or so days. You need a model that predicts future difficulty values so that you can come up with a reasonable result.

While i thought of the idea of implementing that,
i feel most coins are currently to unstable to unleash a single mathematical
function over all of them and predict the future profit.

Im planning on getting this up on a website and taking educated guesses based
on the currency and difficulty fluctuations of the past few weeks, this would
also include an integrated version of the coin prices etc(and maybe even actual
part prices). But this is not easely achieved in a spreadsheet (or i dont know how).

For now i just wanted to share the spreadsheet,
u can however, if u predict the currency will go up, put a slightly higher number
in the Coin Profit part (around B51). I know its a bit of a crappy workaround,
but still...

Well, i hope everyone has fun with the spreadsheet for now
