How to use: Determine cryptocurrency mining profitability after electricity costs. Enter Hash Rate in TH/s (terahashes per second - mining rig computing power), Power Consumption in watts (typical ASIC miners use 3000-3500W), Electricity Cost per kWh (US average $0.12, varies by location), and Pool Fee percentage (typically 1-2%). Results show: Daily Revenue estimate, Monthly Cost for electricity, and net Monthly Profit. Mining profitability fluctuates with crypto prices, network difficulty, and halving events. Break-even requires positive monthly profit. Consider hardware costs and cooling needs.
