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.
Bitcoin Mining Economics After the 2024 Halving
The April 2024 halving cut issuance to 3.125 BTC per block, structurally shifting miner revenue toward transaction fees over the long run. During bursts of on-chain activity (Ordinals, Runes) fees can briefly rival the subsidy, but on average they remain a single-digit percentage of block revenue — so the BTC price and your hardware's joules-per-terahash still dominate your margin.
Network difficulty trends upward as efficient machines deploy, meaning the BTC earned per TH/s falls over time even at a constant price. Model your breakeven with a buffer for several percent of quarterly difficulty growth, and treat the ASIC itself as a depreciating asset to amortize over 12–24 months.
Hosted vs Home Bitcoin Mining
At US residential rates of $0.10–$0.15/kWh, a single modern ASIC often produces thin or negative margins once difficulty growth and 75–85 dB noise are accounted for. This is why serious miners colocate in hosting facilities at $0.06–$0.08/kWh all-in, or self-mine behind cheap and curtailed energy such as flared gas, hydro, or solar-plus-storage.
If you mine at home, the realistic path to profit is heat reuse (workshop or garage heating in winter) or running only when spot power is cheapest. Use the electricity field above to test several rates — the gap between $0.12 and $0.06/kWh frequently flips a machine from loss to profit.
