Your calculations are a solid start, but there are a few things that might affect your profitability. Mining pools usually charge fees (1-2%), which reduce earnings, and network difficulty increases over time, so the 0.01 BTC/day estimate might drop. Don't forget about maintenance costs or potential downtime either, as they can impact your profits.

I've been using ASICprofit to get a clearer picture of mining profitability. It accounts for difficulty adjustments and hidden costs, making it easier to plan ROI accurately. You can also try tools like Whattomine or Minerstat for real-time updates and comparisons.

Double check all your inputs and factor in every cost to make sure the numbers hold up. Good luck!
