This comparison covers the full cost picture for both approaches. It is a cost analysis, not a profit projection. Mining revenue depends on BTC price and network difficulty, which neither approach controls.
How Much Does It Cost to Run a Bitcoin Miner at Home vs. Hosted?#
Running one bitcoin miner at home costs about $460 a month in electricity for a typical 3.5 kW ASIC running 24/7 at the US residential average of 18.3 cents per kWh (EIA, July 2026). Hosted at Fathom Labs' $0.07/kWh all in rate, the same machine costs about $176. Home mining also adds cooling, a dedicated 20A circuit, and noise.
| Cost Factor | Home Mining | Hosted at Fathom Labs |
|---|---|---|
| Electricity rate | ~$0.18/kWh (US residential avg, EIA, July 2026) | $0.07/kWh all in |
| Monthly elec. cost (3,500W, 24/7) | ~$461 | ~$176 |
| Cooling overhead | Significant, ventilation, A/C | Included in rate |
| Noise (~75 to 85 dB) | Loud in residential space | Professional facility, not your concern |
| Electrical infrastructure | Dedicated 20A circuit required; possible panel upgrade | Included in facility |
| Hardware insurance | Separate policy needed | Separate policy needed (not included in the installation fee) |
| Monitoring/operations | Your time | 24/7 NOC included |
| One time setup cost | Electrical work (varies) | $30 installation fee |
Monthly electricity figures: (3.5 kW × 720 h) × rate. Home rate = $0.183/kWh, the US residential average for July 2026 (EIA Electric Power Monthly), which varies widely by state; hosted rate = $0.07/kWh for miners bought from Fathom Labs ($0.08/kWh, minimum 10 units per order, for miners you already own). These are electricity cost estimates only, not profit projections.
When Home Mining Can Make Sense#
Home mining is viable when you have access to electricity at or below approximately $0.06 to $0.07/kWh, through off grid solar, a very cheap rural utility rate, or negotiated industrial power. It also works for small scale experimentation where physical access to the machine is part of the goal. For the majority of residential miners, these conditions do not apply, and the electricity rate differential, combined with the hidden costs above, makes professional hosting the more cost effective path.
