Bitcoin Mining Profitability Calculator
Calculate BTC mining profit from hash rate, electricity cost, pool fees, and difficulty. Enter values for instant results with step-by-step formulas.
Formula
Daily BTC = (Hash Rate × 86,400 × Block Reward) / (Difficulty × 2^32)
Bitcoin mining revenue is calculated by dividing your hash rate's contribution by the total network difficulty. Multiply your hash rate (in hashes per second) by 86,400 seconds per day and the block reward (3.125 BTC). Divide by the network difficulty multiplied by 2^32. Daily profit equals daily revenue minus daily electricity cost, where electricity cost = power (kW) × 24 hours × rate per kWh.
Worked Examples
Example 1: Antminer S21 XP Profitability
Problem: Calculate daily profitability for an Antminer S21 XP (270 TH/s, 3,645W) with electricity at $0.08/kWh and BTC at $60,000 (difficulty: 80T).
Solution: Daily BTC = (270 × 10^12 × 86400 × 3.125) / (80 × 10^12 × 2^32)\n= 0.00021226 BTC\nDaily Revenue = 0.00021226 × $60,000 = $12.74\nDaily Electricity = (3.645 kW) × 24h × $0.08 = $7.00\nDaily Profit = $12.74 - $7.00 = $5.74
Result: Daily BTC: 0.00021226 | Revenue: $12.74 | Cost: $7.00 | Profit: $5.74
Example 2: Break-Even Analysis
Problem: At what electricity price does the same Antminer S21 XP break even with BTC at $60,000?
Solution: Daily Revenue = $12.74\nDaily kWh = 3.645 × 24 = 87.48 kWh\nBreak-Even Price = $12.74 / 87.48 kWh = $0.1456/kWh\nAny electricity cost above $0.1456/kWh makes mining unprofitable
Result: Break-Even Electricity: $0.1456/kWh
Frequently Asked Questions
How is Bitcoin mining profitability calculated?
Bitcoin mining profitability is determined by comparing mining revenue against operating costs. Revenue is calculated using the formula: Daily BTC = (Hash Rate × 86400 × Block Reward) / (Difficulty × 2^32). The hash rate represents your mining hardware's computing power in terahashes per second (TH/s). The block reward is currently 3.125 BTC after the April 2024 halving. Network difficulty adjusts every 2,016 blocks (approximately every two weeks) to maintain a 10-minute average block time. Operating costs primarily consist of electricity consumption. Your daily electricity cost equals power consumption in kilowatts multiplied by 24 hours multiplied by your electricity rate per kWh.
What is the current Bitcoin block reward and when is the next halving?
The current Bitcoin block reward is 3.125 BTC per block, which took effect after the fourth halving in April 2024. Bitcoin halvings occur approximately every 210,000 blocks (roughly every four years), reducing the block reward by 50%. The next halving is expected around 2028, which will reduce the reward to 1.5625 BTC. Previous halvings occurred in 2012 (50 to 25 BTC), 2016 (25 to 12.5 BTC), and 2020 (12.5 to 6.25 BTC). Halvings are significant for mining profitability because they immediately cut revenue in half, forcing less efficient miners out of the network. This reduction in supply issuance is also a key factor in Bitcoin's scarcity-driven value proposition.
What hash rate do I need to mine 1 Bitcoin per day?
Mining 1 BTC per day requires an extraordinarily high hash rate that is beyond the reach of individual miners. With the current network difficulty around 80 trillion and a block reward of 3.125 BTC, you would need approximately 460 PH/s (petahashes per second) or 460,000 TH/s to mine 1 BTC daily on average. For perspective, the most powerful consumer ASIC miner (such as the Antminer S21 XP) produces about 270 TH/s, meaning you would need roughly 1,700 of these machines. This would consume approximately 5.5 megawatts of power and cost millions in hardware alone. Individual miners typically earn fractions of a bitcoin and join mining pools for more consistent payouts.
What is the most efficient Bitcoin mining hardware in 2025?
The most efficient Bitcoin ASIC miners in 2025 achieve power efficiency below 20 joules per terahash (J/TH). Leading models include the Antminer S21 XP (270 TH/s at 3,645W, ~13.5 J/TH), the MicroBT Whatsminer M66S (298 TH/s at 5,365W, ~18 J/TH), and the Canaan Avalon A1566 (185 TH/s at 3,420W, ~18.5 J/TH). Efficiency is the most critical factor in mining profitability because it determines how much electricity you consume per unit of hash power. A miner with 15 J/TH efficiency will use half the electricity of a 30 J/TH miner for the same hash rate. When evaluating hardware, consider both upfront cost and long-term operating efficiency, as electricity is typically the largest ongoing expense.
How does Bitcoin mining difficulty affect profitability?
Bitcoin mining difficulty directly impacts how much BTC you can mine with a given hash rate. Difficulty adjusts every 2,016 blocks to ensure an average block time of 10 minutes. When more miners join the network (increasing total hash rate), difficulty increases, reducing each miner's share of rewards. When miners leave, difficulty decreases, making mining more profitable for remaining participants. Over Bitcoin's history, difficulty has generally trended upward as more powerful hardware is deployed. Between 2020 and 2024, difficulty increased by over 300%. Rising difficulty means miners must continuously upgrade to more efficient hardware to maintain profitability. During bear markets, some miners shut down unprofitable operations, causing difficulty to drop and creating opportunities for remaining miners with low electricity costs.
How does cryptocurrency mining work?
Mining uses computing power to solve cryptographic puzzles and validate transactions. Miners earn block rewards and transaction fees. Proof-of-Work mining requires specialized hardware (ASICs or GPUs) and consumes significant electricity.
