Hey Guys,

This may seem like a dumb question but honestly, I am stuck on this and finding various answers from all over, however, I am not finding what I need.

I need the formula for calculating bitcoin mining profitability based on block difficulty and hash rate, power costs and equipt costs will obviously be subtracted.

Few more questions, does the formula change with different coins?

I'm looking at a model like this, however, I also found out that it could change based on what payout scheme the pool is using, whether its PPLNS or PPS.

Reward = ((hashrate * block_reward) / current_difficulty) * (1 - pool_fee) * 3600

I have found tons of profitability calculators, however, I can't find the actual base formula or model they are using to calculate it.

What I need is basically the profit per Terahash given the current difficulty.

Thanks!
