Bitcoin (BTC) Mining Calculator
Bitcoin is mined using the SHA-256 proof-of-work algorithm, which requires dedicated ASIC hardware. Following the April 2024 halving, the block reward dropped to 3.125 BTC per block found approximately every 10 minutes. With network hashrate running between 700–900+ EH/s in 2026, profitability is tightly linked to your hardware's efficiency ratio (joules per terahash) and your electricity cost.

Best Hardware for Bitcoin Mining
Current-generation Bitcoin ASICs (2025–2026): Antminer S21 Pro (234 TH/s, 3510W, ~15 J/TH) — top-tier efficiency for industrial deployments; Whatsminer M66S+ (~280 TH/s, ~20 J/TH) — high raw hashrate, slightly less efficient; Antminer S21 XP Hyd (473 TH/s, hydro-cooled) — highest hashrate per unit, requires liquid cooling infrastructure. For air-cooled home or small-scale setups, the Antminer S19k Pro (136 TH/s, 2760W, ~20 J/TH) remains a cost-effective entry point. The efficiency threshold for profitability at US residential rates ($0.10–$0.13/kWh) is approximately 20–22 J/TH at current BTC prices.
About Bitcoin Mining
The single most important metric for any Bitcoin miner in 2026 is <strong>joules per terahash (J/TH)</strong>. The lower your ratio, the more Bitcoin you earn per dollar of electricity spent. First-generation ASICs like the Antminer S9 (90+ J/TH) are permanently unprofitable at any commercially available electricity rate. Current top-tier machines like the Antminer S21 Pro (~15 J/TH) cut electricity cost per TH by over 80% compared to S9-era hardware, which is why the 2024 halving accelerated generational hardware turnover rather than killing the industry.
Use this calculator to estimate your daily, weekly, and monthly Bitcoin earnings based on your specific hardware and electricity situation. The results update automatically as network difficulty and BTC price change — recalculate before making any hardware purchase decision.
