Bitcoin Mining Calculator
Estimate what a fleet of ASIC miners earns and spends per day, month and year. Network difficulty, block reward and BTC price load live from mempool.space, and every value can be changed.

$83.87 / MWh = $0.084 / kWh
Load: 35.0 kW for 2.00 PH/s, which about 8 mcf/d of natural gas could power.

Expected BTC = hashrate × time × block reward ÷ (difficulty × 2³²), less the pool fee. Revenue is that BTC at the price entered; power cost is the miners' draw × 24 hours × your electricity price.
- Block reward: the 3.125 BTC subsidy plus the average transaction fees over the last 144 blocks (about one day).
- Break-even power price: the electricity price at which revenue equals power cost. It shows whether a gas or power asset suits mining.
- Hardware break-even: price of the miners ÷ daily profit, at today's difficulty and price.
- Power draw: the machines' rated wall power. Site overhead such as cooling and transformers adds to it, often 3–10%.
Difficulty rises over time, the 2028 halving cuts the subsidy to 1.5625 BTC, and the BTC price moves daily, so real results will differ. Treat the result as a snapshot, not a forecast.
Frequently asked questions
- How much does one bitcoin miner earn per day?
- An S21-class machine (200 TH/s, 3,500 W) mines about 0.00009 BTC a day at network values from 2026-10-28, worth about $7.05 before power. At $0.05/kWh its power costs $4.20 a day.
- What electricity price makes bitcoin mining profitable?
- Mining is profitable after power costs while your electricity costs less than the break-even price: the revenue each kWh earns. For a 17.5 J/TH machine that was about $0.084 per kWh at network values from 2026-10-28. More efficient machines tolerate higher power prices.
- Can flared or stranded gas power bitcoin mining?
- Yes. A gas generator on site turns gas that would be flared into power for the miners. 1 MMscf/d runs roughly 4.4 MW, enough for about 1,260 S21-class machines, and containerized miners need no grid connection, so they can be deployed quickly.
- Why does the result change from day to day?
- Difficulty adjusts about every two weeks, fees vary from block to block and the BTC price moves constantly. The calculator loads the latest values each time you open it.
