Ethereum Mining Profitability Guide
Ethereum moved away from proof-of-work mining, so this calculator is best used for historical studies, legacy planning, or Ethash-style comparison projects. It still helps users understand how mining economics worked. It also helps compare hardware, electricity rates, and pool deductions.
Why Profit Changes
Mining profit depends on many moving values. Hashrate shows your share of total network power. Block reward shows expected coin creation. Coin price turns that coin amount into revenue. Power draw and energy price turn hardware use into a daily cost. Pool fees and maintenance reduce the final amount.
A small rate change can matter. High electricity cost can erase strong hashrate gains. A higher coin price can improve returns. A larger network hashrate can lower your expected share. That is why realistic inputs are important.
Important Inputs
Start with miner hashrate. Use the unit selector carefully. Then enter power draw from the wall, not only card power. Add your electricity price per kilowatt hour. Include pool fee, uptime, and maintenance. Use hardware cost when you want payback estimates.
Network values are also important. The calculator uses network hashrate, block reward, and average block time. These values create expected coins per day. They do not promise exact payouts. Real mining results can vary because blocks, pool luck, downtime, and fees change.
Reading the Result
The result shows estimated coin output first. It then shows gross revenue, electricity cost, pool fee, maintenance, and net profit. Daily, monthly, and period totals make comparison easier. Payback time is shown only when daily profit is positive. Return on investment compares period profit against hardware cost.
Use the export buttons for records. CSV is useful for spreadsheets. PDF is useful for client notes or project files.
Practical Advice
Run several scenarios before buying equipment. Test low, normal, and high coin prices. Compare different electricity rates. Try lower uptime if cooling or outages are uncertain. Add maintenance when fans, risers, cables, or repairs are expected.
This tool is an estimator. It should not replace live network data, tax advice, or financial planning. It is most useful when inputs are reviewed often. Keep assumptions conservative, and compare results with actual meter readings. Save every export for later audit checks too.
