BITMAIN

BITMAIN is a China‑based technology company that makes specialized computers for cryptocurrency mining, best known for its ANTMINER machines used to mine Bitcoin.

Unlike a normal PC, a Bitmain miner uses ASIC chips—chips built for one job: solving the calculations that secure Bitcoin and other proof‑of‑work networks. Bitmain sells these miners to home users, hosting companies, and large mining farms worldwide.

Bitcoin Profit Calculator

A Bitcoin profit calculator estimates how much a Bitcoin miner could earn after electricity, pool, hosting, and other operating costs. Results change constantly with Bitcoin’s price, mining difficulty, and network hash rate.

What you enter

• Miner model or hash rate in TH/s

• Power use in watts

• Electricity price per kWh

• Pool fee percentage

• Hosting, cooling, and maintenance costs

• Hardware purchase price, if you want ROI/payback time 

Simple formula

Mining revenue is driven by your miner’s hash rate, Bitcoin price, network difficulty, and block reward.

Quick example

An Antminer S21 Pro rated at 234 TH/s and 3,510 W uses about 84 kWh per day. At $0.06/kWh, one recent estimate put it around $7.70/day in gross revenue and roughly $2.70/day net before pool fees; at $0.10/kWh, it ran at a small daily loss.

What matters most

• Electricity rate: Usually the biggest cost; newer ASICs may break even near $0.09–$0.11/kWh under certain network conditions, while older machines need much cheaper power.

• ASIC efficiency: Lower joules per terahash (J/TH) means less electricity for the same mining output. 

• Bitcoin price and difficulty: A higher BTC price raises revenue; higher difficulty lowers the BTC earned per machine.

• Full ROI: Include the machine purchase, shipping, electrical work, hosting, downtime, repairs, depreciation, and taxes—not only daily power costs.

A calculator gives an estimate, not a guaranteed profit. Use current values immediately before making a mining decision.

antminer

Antminer is Bitmain’s brand of specialized crypto‑mining machines. Most Antminers are ASICs—computers designed to run one mining algorithm extremely efficiently, rather than functioning like a normal PC.

What an antminer does

For Bitcoin, an Antminer repeatedly performs SHA‑256 hashes to compete for the right to add a transaction block to the Bitcoin blockchain. Most owners join a mining pool, which distributes Bitcoin rewards according to each miner’s contributed work.

Bitcoin’s current block subsidy is 3.125 BTC plus transaction fees, but an individual Antminer generally earns only a small pooled share—not a whole block reward.

Main types of antminers

An Antminer’s algorithm is fixed. For example, a Z15K cannot mine Bitcoin because it was made for Equihash rather than Bitcoin’s SHA‑256 algorithm.

Specs that matter

• Hash rate: Mining speed, commonly measured in TH/s for Bitcoin miners; more hash rate means a larger share of pool rewards. 

• Power draw: Electricity use, measured in watts. Many full-size units draw roughly 1–6 kW continuously.

• Efficiency: Usually measured in J/TH for Bitcoin miners; lower is better because it uses less electricity per unit of work. 

• Cooling and noise: Air-cooled units use high-speed fans and can be very loud; hydro-cooled models need an external coolant loop and heat exchanger.

Current examples

• S21 Pro: About 234 TH/s, 15 J/TH; a widely used air-cooled Bitcoin-mining option.

• S21 XP: About 270 TH/s, 13.5 J/TH, with roughly 3,645 W wall draw. bitcoinfoundation+1

• S23 Hyd: Around 580 TH/s, 9.5 J/TH, but it is hydro-cooled and intended for industrial infrastructure. bitcoinfoundation+1

• L9: Roughly 15–17 GH/s at about 3.3 kW for Litecoin/Dogecoin Scrypt mining.
