How It Works
Understanding Key Metrics
J/TH (Joules per Terahash)
This is the most important efficiency metric for mining hardware. It measures how many Joules of energy are consumed per Terahash of computation. Lower is better. Modern miners like the Antminer S21 XP achieve ~13.5 J/TH, while older models may exceed 30 J/TH. This metric directly correlates with your electricity cost per BTC mined.
Break-Even Electricity Price
This is the maximum electricity rate (per kWh) at which your mining operation generates zero profit — revenue exactly covers electricity costs. If your actual rate is below this number, you're profitable. Many profitable miners operate at $0.03-$0.06/kWh.
Network Difficulty
Bitcoin's protocol adjusts mining difficulty every 2,016 blocks (~2 weeks) to maintain a 10-minute average block time. As total network hash rate grows, difficulty increases, reducing each miner's share of rewards. Historically, difficulty has grown at roughly 3-5% per month during bull markets.
Frequently Asked Questions
How much electricity does it cost to mine 1 Bitcoin?
The electricity cost to mine 1 BTC varies greatly based on your hash rate, hardware efficiency, and local electricity price. With a modern ASIC miner (e.g., Antminer S21 XP at 270 TH/s, 3645W) and $0.10/kWh electricity, it costs approximately $70,000-$80,000 in electricity per BTC. Use this calculator with your specific setup for an accurate estimate.
Is Bitcoin mining still profitable in 2026?
Bitcoin mining profitability depends on several factors: your electricity cost, hardware efficiency (J/TH), the current BTC price, network difficulty, and pool fees. After the April 2024 halving (block reward reduced to 3.125 BTC), miners need efficient hardware and cheap electricity (ideally below $0.06/kWh) to remain profitable. This calculator helps you determine your specific profitability.
What is the break-even electricity price for Bitcoin mining?
The break-even electricity price is the maximum you can pay per kWh while still covering your mining revenue. It depends on your hash rate, hardware efficiency, BTC price, and network difficulty. This calculator computes your specific break-even electricity price based on your inputs.
How does network difficulty affect mining profitability?
As more miners join the Bitcoin network, the mining difficulty increases, meaning each miner earns a smaller share of block rewards. Historically, difficulty has grown at roughly 2-5% per month. This calculator includes a difficulty adjustment parameter so you can project how your profitability may change over the next 12 months.
What is J/TH and why does it matter?
J/TH (Joules per Terahash) measures hardware energy efficiency — how much electricity a miner uses per unit of hash power. Lower J/TH means better efficiency. Modern miners like the Antminer S21 XP achieve ~13.5 J/TH, while older models may exceed 30 J/TH. This metric directly impacts your electricity cost per BTC mined.
Mining Assumptions
- Block Reward: 3.125 BTC per block (post-April 2024 halving). Next halving expected around April 2028.
- Blocks Per Day: 144 blocks (one block every ~10 minutes on average).
- Network Hash Rate: ~1,050 EH/s (as of early 2026). This is used to estimate your share of mining rewards.
- Pool Fee: Default 1%. Most major mining pools charge 1-2%.
- Difficulty: Adjusts every 2,016 blocks. Monthly growth rate is customizable in this calculator.
