Bitcoin (BTC) Mining Calculator

As of Jul 7, 21:12 UTC, the top-ranked Bitcoin miner on CoinWarz is the Antminer U3S23H 1160TH/s (1160 TH/s, 11,020 W), earning about $0.000719 per watt per day and $7.92 net daily profit at $0.10/kWh electricity. Rankings are recalculated with live network difficulty and BTC price, so the leader can change as conditions move.

Electricity is the largest ongoing cost in Bitcoin mining. Daily power cost = (watts ÷ 1,000) × 24 hours × your USD/kWh rate. Example: a 11,020 W ASIC costs $26.45/day at $0.10/kWh but $13.22/day at $0.05/kWh - that difference often decides whether a machine is profitable at all. CoinWarz defaults to $0.10/kWh; enter your actual rate for accurate results.

Profit per Watt is net daily mining profit in USD divided by the miner's power draw in watts (USD/W/day). Most mining operations are constrained by available electrical capacity, not by how many machines they can buy - a 200 A residential panel or a fixed megawatt allocation caps total watts. Ranking hardware by Profit per Watt shows which ASIC earns the most from a fixed power budget, which makes it more actionable than raw hashrate or J/TH efficiency alone. CoinWarz uses it as the headline metric on every calculator and ranking page.

The calculator uses live inputs: Bitcoin network difficulty is recorded per block from a synced full node, and the BTC price is refreshed from the CoinGecko API every 10 minutes. Results are point-in-time estimates that hold current difficulty and price constant - they do not model future difficulty adjustments (roughly every two weeks), pool luck, orphan rates, transaction-fee variance, or hardware downtime. CoinWarz has published mining profitability data since 2013.

BTC mined per day = block reward × blocks per day × (your hashrate ÷ estimated network hashrate). Network hashrate is derived from on-chain difficulty (difficulty × 2³² ÷ block time for SHA-256). Bitcoin averages 144 blocks per day (10-minute target) with a 3.125 BTC subsidy. Example: the calculator's default top ASIC against the current ~958 EH/s network earns about 0.00054473 BTC per day of pooled hashrate.

Days to mine 1 BTC = 1 ÷ BTC mined per day. With a mining pool you earn a steady fraction of each block reward proportional to your hashrate share, so this is an accumulation time, not a lottery wait. At current difficulty, a single top-ranked ASIC accumulates 1 BTC in roughly 1,836 days (about 5 years); ten of the same machines would take one-tenth as long.

The current Bitcoin block subsidy is 3.125 BTC per block, plus transaction fees. At the 10-minute target block time the network produces about 144 blocks per day, or roughly 450 new BTC daily. The subsidy halves every 210,000 blocks (about four years); the next halving is expected in 2028, when it drops to 1.5625 BTC.

Yes - for miners with efficient hardware and competitive electricity. Profitability depends on three inputs you control (hardware efficiency, power rate, uptime) and three you don't (BTC price, network difficulty, block reward). At $0.10/kWh, the current top-ranked ASIC (Antminer U3S23H 1160TH/s) nets about $7.92 per day. Older or less efficient hardware can be unprofitable at the same rate - check your exact setup in the calculator.
