Mining Economics and Profitability

Calculating Profitability

Essential formulas:

1. Daily revenue = (Your hashrate ÷ Network hashrate) × Block reward × Blocks per day × Coin price

2. Daily electricity cost = Power consumption (kW) × 24 hours × Electricity rate ($/kWh)

3. Daily profit = Daily revenue - Daily electricity cost

4. Break-even timeframe = Hardware cost ÷ Daily profit

Profitability calculators:

• CryptoCompare
• NiceHash Calculator
• Mining pool calculators

Understanding Mining Difficulty

Mining difficulty automatically adjusts to maintain consistent block times:

• Increasing network hashrate leads to rising difficulty
• Higher difficulty reduces revenue per unit of hashrate
• Historical difficulty trends help project future profitability
• Difficulty adjustments occur at different intervals depending on the cryptocurrency

Building a Mining Business Plan

For serious miners, creating a business plan helps evaluate viability:
