I need to figure out how to calculate expected payouts from the difficulty + price + hashrate + timeframe. I know there is a online calculator, but I need the actual formula so I can do it myself.

Here you go: Here's the current bitcoin difficulty: http://blockexplorer.com/q/getdifficulty. I reduced the formula down to: average BTC per Day = (megahashes per second / difficulty) * 1005.82838 so: 100 megahashes/s at 1379223.4296725 difficulty = ( 100 / 1379223.4296725 ) * 1005.82838 = .07292715 BTC per day Add ~1% in transaction fee wins (if paid by pool), subtract downtime, connectivity issues, and rejected block overhead, and subtract pool fees. If you join a large pool that solves several blocks a day your results will be very close to this. If you are solo mining with a GPU, it is more like a lottery  although stats say it would average eight months to win 50 BTC at current difficulty with a good ATI GPU, you might win it tomorrow or you might never win in your lifetime.

You know where he is getting 1005.82838 from?

You know where he is getting 1005.82838 from? Yes I do, because he is me! From the probability of finding a block solution with a single hash and the formula that relates that to difficulty, with lots of algebra carrying the units.

I need to do weekly payouts to investors based on 100/mh per share rate. The online calculators don't seem to be very accurate. There should be a relatively simple method to figuring it out each week..

Now I can cut my spreadsheet formulas down.

Unless you factor in the block halving this year.
