Bitcoin Mining Profitability Calculator
Estimate daily, monthly and annual Bitcoin mining profit from your rig's hashrate, power draw, your electricity cost per kWh, and current network conditions. The calculator pre-fills the live BTC spot price (from Binance) and the live Bitcoin network hashrate (from mempool.space, cached for 1 hour), so you only have to plug in the hardware spec and your power tariff.
The key output most mining ROI calculators don't show is the break-even BTC price — the spot price at which your daily revenue exactly covers your daily electricity cost. Above that, the rig prints money. Below that, the rig burns money and you're better off turning it off (or running curtailment in regions where power prices are time-of-use).
Block reward 3.125 BTC post-2024 halving · 144 blocks/day. Live BTC price $62,618 pre-filled.

How it's calculated
Expected daily BTC ≈ (your hashrate ÷ network hashrate) × 3.125 BTC × 144 blocks/day. Daily revenue = that × BTC price × (1 − pool fee %). Daily power cost = (watts ÷ 1000) × 24 × $/kWh. Profit = revenue − power cost. Block reward is the post-2024-halving value of 3.125 BTC and shifts to 1.5625 BTC at the 2028 halving.
Network difficulty re-targets every 2,016 blocks (~2 weeks). When difficulty rises, your hash share drops proportionally and so does your daily BTC. The calculator uses the most recently published hashrate to estimate this; for budgeting purposes assume modest difficulty growth across the year.
Worked example
An Antminer S21 (200 TH/s, 3,500 W) at $0.07/kWh, with network hashrate around 600 EH/s and BTC at $60,000: hash share ≈ 0.000033%. Daily BTC ≈ 0.000150, daily revenue ≈ $9.00 after a 2% pool fee. Power cost ≈ $5.88/day. Daily profit ≈ $3.12 — about $94/month. Break-even BTC price ≈ $39,200 — below that and the rig burns money.
Flip one variable to see the sensitivity. Same rig at $0.04/kWh (e.g. an off-grid solar setup): power cost drops to $3.36/day, profit rises to $5.64/day, and break-even BTC falls below $30,000 — meaningful headroom against another major drawdown. At $0.15/kWh (typical residential US): power cost is $12.60/day, profit is −$3.60, and break-even sits above $84,000 — the rig is unprofitable at today's BTC price.
Mining Profitability Calculator — what changes the answer most
Three variables dominate mining profitability: electricity cost per kWh, BTC spot price, and network difficulty. Hardware efficiency (J/TH) feeds into the first via power draw. A common mistake on free mining calculators is treating BTC price as the variable to flex; in practice your electricity contract is the variable that determines whether the rig is profitable at all. Mining at $0.04/kWh is profitable at almost any modern BTC price; mining at $0.15/kWh is unprofitable at almost any modern BTC price. That's why industrial miners chase stranded hydro, flared gas, and curtailment programmes — the spread between $0.02 and $0.05 is bigger than the spread between $40k and $80k BTC.
BTC Mining Calculator: comparing rigs
To compare two Antminer or Whatsminer models head-to-head, run the calculator twice and compare the profit row. Newer hardware usually has a higher hashrate (good) AND a higher power draw (bad); efficiency in J/TH is what nets out. An S21 Pro at 234 TH/s and 3,510 W (~15 J/TH) is fundamentally more profitable per BTC mined than an older S19 Pro at 110 TH/s and 3,250 W (~29.5 J/TH), even though both pull similar wall power — the newer rig mines roughly 2.1× as much BTC for the same electricity cost. The calculator surfaces this directly: same kWh column, very different daily BTC and daily profit columns.
Ethereum mining calculator and other coins
We're building a dedicated Ethereum mining calculator as part of the next tools batch — proof-of-stake means ETH itself isn't mineable in the traditional ASIC sense anymore, but coins running similar Ethash forks (ETC, etc.) and other GPU-mineable assets still use the same profitability framework. Until that page ships, you can model GPU mining here by setting hashrate in MH/s and treating block reward and network hashrate as the relevant coin's. The formula doesn't care which coin you're mining; it cares about reward × your share of total network.
FAQ
How is mining profitability calculated?
Profit = mining rewards earned minus electricity and pool costs. It depends on your hashrate, the network difficulty, the coin price, your power consumption and your electricity rate. The calculator combines these into an estimated daily, monthly and yearly profit.
What inputs do I need?
Your hardware's hashrate, its power draw in watts, your electricity cost per kWh, and any pool fee. The calculator supplies current network difficulty and coin price.
Why does electricity cost matter so much?
Power is usually the largest ongoing mining expense. A small change in your cost per kWh can flip a rig from profitable to loss-making, so it's the most important variable to get right.
Are these estimates guaranteed?
No. Difficulty, coin price and rewards change constantly, so real results will vary. Treat the output as an estimate based on current conditions, not a guarantee.
