Is there some sort of calculator to estimate how many coins I can mine in a day or a week?
Here I made this for you quickly for an educated guess. (y/z)(2222222/(((x+2600)/9)^2)) You can enter the formula at wolframalpha.com and change the numbers
X = the current difficulty
Y = Your hashrate
Z = Total network hashrate
Example given in khash/sec below (you can use ghash/sec as long as you keep Y and Z in the same measure)
(50000/6210000)(2222222/(((224+2600)/9)^2)) = 0.1817 approx
In this example, the current network hashrate is 6.21 Ghash (right now that's what it's at) , you are hashing at 50 mhash (or 0.05 ghash to keep the same measure) and the network difficulty is 224. That gives you 0.1817 DRK per block. There's 24 blocks per hour which gives 4.3608 DRK/hour or 104.6592 DRK/day
Hope that helped and hope I'm right also.
edit : also I'm no expert with pools, so I'm not sure if being in a larger or smaller pool affects this calculation.
edit 2 : just checked in the official pool and my calculation seem to be right on the money ( the 50k being khash and the 100 something being drk/day)
