Profitability & ROI calculator • 2026 edition
\( \text{Daily Profit} = \left(\frac{\text{Hash Rate} \times 86400}{\text{Network Hash Rate}} \times \text{Block Reward}\right) \times \text{BTC Price} - \text{Daily Energy Cost} \)
Where:
This formula calculates net daily profit after accounting for electricity costs.
Example: With 100 TH/s, 300 EH/s network, $50,000 BTC price, 3.5kW power at $0.10/kWh:
Daily revenue: (100 × 86400 / 300,000,000) × 6.25 × 50,000 ≈ $90.00
Daily cost: 3.5 × 24 × 0.10 = $8.40
Net profit: $90.00 - $8.40 = $81.60 per day
Bitcoin mining is the process of validating transactions and adding them to the blockchain ledger. Miners compete to solve cryptographic puzzles using computational power, earning Bitcoin rewards for successful blocks.
Daily Profit = (Revenue from Mining) - (Energy Costs)
Where Revenue = (Hash Rate / Network Hash Rate) × Blocks per Day × Block Reward × BTC Price
Bitcoin mining profitability depends on several key factors:
Profitability = (Reward - Cost) where Cost = Energy Cost + Pool Fees + Maintenance
Blocks per day: 144 (24 hours × 60 minutes / 10 minutes per block)
Your share of network: Hash Rate / Network Hash Rate
Daily revenue: (Your Share × Blocks per Day × Block Reward) × BTC Price
Energy cost: Power (kW) × Hours × Electricity Rate
Net profit: Daily Revenue - Energy Cost - Pool Fees
Mining efficiency is measured in joules per terahash (J/TH):
Lower values indicate more efficient hardware. Modern ASICs achieve 30-60 J/TH.
Which factor has the greatest impact on Bitcoin mining profitability?
The answer is B) Electricity cost. For most miners, electricity costs represent 60-80% of total operational expenses. Even with efficient hardware, high electricity costs can make mining unprofitable regardless of Bitcoin price.
While Bitcoin price and network hash rate affect revenue, electricity cost directly impacts the bottom line. A miner in a location with $0.05/kWh electricity can be profitable when the same setup in a $0.25/kWh location would be losing money. This is why miners seek locations with cheap renewable energy.
Energy Efficiency: Power consumed per unit of computational work
Operational Expenses: Recurring costs of running mining operations
Profit Margin: Difference between revenue and costs
• Electricity cost is the largest expense for most miners
• Location significantly impacts profitability
• Efficiency improvements directly increase profits
• Look for electricity rates below $0.10/kWh for profitability
• Consider seasonal variations in electricity pricing
• Underestimating electricity costs
• Ignoring cooling and maintenance expenses
A mining rig costs $10,000, has a hash rate of 100 TH/s, consumes 3.5kW, and electricity costs $0.10/kWh. If the daily profit is $50, calculate the ROI and payback period.
Payback Period = Initial Investment / Daily Profit
Payback Period = $10,000 / $50 = 200 days
Annual Profit = $50 × 365 = $18,250
ROI = (Annual Profit / Initial Investment) × 100
ROI = ($18,250 / $10,000) × 100 = 182.5%
After 200 days, the investment is recovered. After one year, the return is 182.5%.
This calculation shows the importance of daily profitability in determining investment returns. The payback period indicates how quickly the initial investment is recovered. ROI measures the return relative to the investment. In this example, the mining operation generates significant returns, but these calculations assume constant conditions which rarely occur in mining.
Return on Investment (ROI): Percentage return relative to investment cost
Payback Period: Time to recover initial investment
Net Present Value: Current value of future cash flows
• Consider changing market conditions
• Account for equipment depreciation
• Include maintenance and operational costs
• Use conservative estimates for Bitcoin price
• Factor in rising difficulty over time
• Ignoring changing network difficulty
• Overestimating Bitcoin price stability
Q: How does mining difficulty affect profitability?
A: Mining difficulty adjusts every 2,016 blocks (approximately every 2 weeks) to maintain a 10-minute block time. As more miners join the network, difficulty increases, making it harder to mine blocks.
Mathematically, if difficulty doubles, your chance of finding a block halves (assuming constant hash rate). The relationship is:
Probability of Finding Block = Your Hash Rate / Network Hash Rate
Higher difficulty means higher network hash rate, reducing your share of the total network and thus your expected rewards.
Q: What are the main risks in Bitcoin mining investments?
A: Bitcoin mining involves several key risks:
Successful mining operations require careful risk management and diversification strategies.
