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.

Frequently Asked Questions
- How is Bitcoin mining profitability calculated?
- The calculator divides your miner's hashrate by the current Bitcoin network hashrate to estimate your share of block rewards. Network hashrate is derived from current difficulty using the formula: hashrate = difficulty × 2³² ÷ 600 seconds. Your estimated BTC per day = (your hashrate ÷ network hashrate) × 144 blocks/day × 3.125 BTC/block.
- What electricity rate does this calculator use?
- The Southeast Texas hosting location uses an all-in rate of $0.07 per kWh, which covers electricity, facility costs, and management. This is the fixed rate in our hosting contract. There are no hidden fees.
- Does this calculator guarantee profit?
- No. All results are estimates based on the BTC price and network difficulty at the moment of calculation. Both change continuously — sometimes dramatically within a single day. The calculator assumes 24/7 uptime with no downtime, hardware failure, or pool variance. Actual results will vary.
- Why does the M73 (hydro-cooled) show higher electricity cost than the M70?
- The M73 draws 7,200W compared to 3,500W for the M70/M70S. Hydro cooling enables the M73 to run at far higher total hashrate (470 to 526 TH/s vs. 242 TH/s), but it is less energy-efficient per terahash: 14.5 J/TH vs. 13.5 J/TH for the M70S. Higher hashrate means higher electricity cost per unit.
- How often does the BTC price update?
- The price is fetched from CoinGecko (Binance as fallback) each time you load or refresh the page. Use the Refresh button to pull the latest price at any time. The timestamp next to the price shows when it was last fetched.
- How much revenue does 1 TH/s generate per day?
- Revenue per TH/s depends on BTC price and network difficulty, so it changes daily. As an illustration: at a BTC price of $105,000 and network difficulty of ~139 T (approximately June 2026 levels), 1 TH/s earns roughly $0.047 per day in gross revenue ($12.25/day for a 258 TH/s M70S). At $0.07/kWh and 13.5 J/TH efficiency, electricity costs roughly $0.023 per TH/s per day, leaving net revenue near $0.024 per TH/s. Use the calculator above for current figures.
- What is the break-even BTC price for my miner?
- The break-even BTC price is the minimum price at which your daily gross revenue equals your daily electricity cost. Formula: Break-even price = (power draw in kW × 24 × electricity rate) ÷ (daily BTC mined). For a Whatsminer M70S hosted at $0.07/kWh with network difficulty around 139 T, the break-even BTC price is approximately $50,400. If BTC trades above that, the miner is cash-flow positive. Below it, electricity costs exceed revenue. Rising network difficulty raises the break-even price; falling difficulty lowers it.
- How do I estimate the payback period for a bitcoin miner?
- Payback period = total upfront cost ÷ daily net revenue. Total upfront cost includes the hardware price plus any one-time fees (at Fathom Labs, a $1,020 per-machine onboarding fee covers installation, insurance, and shipping). Daily net revenue is gross revenue minus electricity cost. For example: a Whatsminer M70 at $4,980 plus $1,020 onboarding = $6,000 total. At a daily net of ~$5.61 (using $105,000 BTC and 139 T difficulty at $0.07/kWh), the estimated payback is about 35 months. Payback shortens when BTC price rises or difficulty falls, and lengthens when either moves the other way. It is not guaranteed.
