How Bitcoin Mining Profitability Is Calculated
Every ~10 minutes, the Bitcoin network awards 3.125 BTC (post-April 2024 halving) to the miner who solves a block. Your share of those rewards is proportional to your share of total network hashrate. The calculator uses this standard formula:
BTC per day = (your hashrate / network hashrate) × 144 blocks/day × 3.125 BTC/block
Network hashrate is not broadcast by the protocol directly — it is derived from network difficulty:
network hashrate = difficulty × 2³² ÷ 600 seconds
Gross revenue equals daily BTC mined multiplied by the spot BTC price. Net revenue subtracts your daily electricity cost (power draw in kW × 24 × $/kWh).
The Five Inputs That Drive the Calculation
- Hashrate (TH/s)
- How much hashing work your miner performs per second. More hashrate earns a larger share of block rewards. The M70 delivers 214–242 TH/s; the M70S delivers 226–258 TH/s; the hydro-cooled M73 delivers 470–526 TH/s.
- Efficiency (J/TH)
- Joules of electricity consumed per terahash of work. Lower is better — it means more mining per dollar of power. The Whatsminer M70S at 13.5 J/TH is the most efficient air-cooled model in the M70 series; the M70 and M73 both run at 14.5 J/TH. Efficiency is fixed by the hardware at the time of purchase.
- Electricity Rate ($/kWh)
- The all-in cost per kilowatt-hour of electricity consumed. This is the most controllable variable in mining economics. Fathom Labs' Southeast Texas facility charges $0.07/kWh all-in — covering electricity, cooling, racking, networking, and monitoring with no separate fees. US residential electricity averages $0.13–$0.16/kWh, making at-home mining substantially less competitive per unit of hashrate.
- Network Difficulty
- Bitcoin's self-adjusting parameter that determines how hard it is to win a block. It recalibrates every ~2,016 blocks (roughly two weeks). Rising difficulty means each miner earns a smaller share; falling difficulty raises earnings proportionally. In 2026, difficulty declined approximately 10.7% across six downward adjustments as compute migrated toward AI and HPC workloads.
- BTC Price (USD)
- The spot price of bitcoin scales gross revenue linearly. A 10% BTC price increase lifts gross revenue by 10%, holding everything else constant. The calculator fetches a live price from CoinGecko (Binance as fallback) each time the page loads. Use the Refresh button to update without reloading.
Worked Example: One M70S at Fathom Labs ($0.07/kWh)
The following uses an illustrative BTC price of $105,000 and network difficulty of 139 T (approximately early-June 2026 levels). Use the live calculator above for current estimates.
| Inputs | |
| Miner | Whatsminer M70S |
| Hashrate | 258 TH/s |
| Power draw | 3,500 W (3.5 kW) |
| Efficiency | 13.5 J/TH |
| Hosting location | Southeast Texas, Fathom Labs |
| Electricity rate | $0.07/kWh (all-in) |
| BTC price (example) | $105,000 |
| Network difficulty (example) | 139 T |
| Estimated Results (per miner) | |
| Daily electricity cost | $5.88 |
| Daily BTC mined | 0.0001167 BTC |
| Daily gross revenue | $12.25 |
| Daily net revenue | $6.37 |
| Monthly BTC mined | 0.003501 BTC |
| Monthly gross revenue | $367.50 |
| Monthly electricity cost | $176.40 |
| Monthly net revenue | $191.10 |
| Break-even BTC price | ~$50,400 |
Break-even BTC price = daily electricity cost ÷ daily BTC mined. Above ~$50,400 this miner is cash-flow positive at $0.07/kWh under these network conditions. Figures assume continuous 24/7 operation at rated hashrate; actual results vary.

常見問題
- 比特幣挖礦收益如何計算？
- 計算器將您礦機的算力除以當前比特幣網絡算力，以估算您在區塊獎勵中的份額。網絡算力根據當前難度使用以下公式推算：算力 = 難度 × 2³² ÷ 600秒。您的估計每日比特幣產量 = （您的算力 ÷ 網絡算力）× 每日144個區塊 × 每塊3.125 BTC。
- 此計算器使用什麼電費費率？
- 德州東南部託管地點採用每度電全包費率 $0.07 美元，涵蓋電力、設施費用和管理費。這是我們託管合約中的固定費率，無任何隱藏費用。
- 此計算器是否保證獲利？
- 不。所有結果均為基於計算當下比特幣價格和網絡難度的估算。兩者均持續變動，有時在同一天內劇烈波動。計算器假設全天候正常運行，不含停機、硬體故障或礦池差異。實際結果會有所不同。
- 為何 M73（液冷）顯示的電費高於 M70？
- M73 功耗為 7,200W，而 M70/M70S 為 3,500W。液冷使 M73 能以更高的總算力運行（470 至 526 TH/s 對比 242 TH/s），但每算力能耗效率較低：14.5 J/TH 對比 M70S 的 13.5 J/TH。更高的算力意味著每台礦機更高的電費成本。
- 比特幣價格多久更新一次？
- 每次載入或重新整理頁面時，價格都會從 CoinGecko（備用：Binance）獲取。隨時點擊「重新整理」按鈕取得最新價格。價格旁邊的時間戳顯示最後獲取時間。
- 每 TH/s 每日可產生多少收益？
- 每 TH/s 的收益取決於比特幣價格和網路難度，每日都會變動。以示範為例：在比特幣價格 $105,000 美元、網路難度約 139 T（約 2026 年 6 月水準）的情況下，每 TH/s 每日毛收益約 $0.047 美元（258 TH/s 的 M70S 每日約 $12.25）。以 $0.07/kWh 電費及 13.5 J/TH 能效計算，每 TH/s 每日電費約 $0.023 美元，淨收益約 $0.024 美元。請使用上方計算機查詢最新數據。
- 礦機的損益兩平比特幣價格如何計算？
- 損益兩平比特幣價格是每日毛收益恰好等於每日電費時的最低比特幣價格。計算公式：損益兩平價格 = （功耗 kW × 24 × 電費費率）÷ 每日挖得比特幣數量。以 $0.07/kWh 託管的 Whatsminer M70S 在網路難度約 139 T 的情況下，損益兩平價格約為 $50,400 美元。比特幣交易價格高於此時，礦機現金流為正；低於此時，電費成本超過收益。網路難度上升會提高損益兩平價格；難度下降則降低損益兩平價格。
- 如何估算比特幣礦機的回本期？
- 回本期 = 總前期成本 ÷ 每日淨收益。總前期成本包含硬體售價加上任何一次性費用（Fathom Labs 每台礦機 $1,020 美元上架費，涵蓋安裝、保險及運輸）。每日淨收益為毛收益扣除電費。舉例：Whatsminer M70 售價 $4,980 加上 $1,020 上架費 = 總計 $6,000。若每日淨收益約 $5.61（以比特幣 $105,000、難度 139 T、電費 $0.07/kWh 計算），估計回本期約 35 個月。比特幣價格上漲或難度下降會縮短回本期，反之則延長。回本期不受保證。
