Every dollar of mining profit survives a gauntlet of costs. This guide breaks down electricity, cooling, maintenance and hardware — and how they shape your real ROI.
To understand mining ROI, you have to understand mining costs. Electricity dominates, but cooling, maintenance and hardware depreciation all take a bite. This guide breaks each one down and shows how hosting with OneMiners compresses them into a single, low, fixed rate.
Key takeaways
- ✓ Electricity is the dominant ongoing cost — often 60–80% of the total.
- ✓ Cooling drives efficiency and hardware longevity; it isn't optional.
- ✓ ROI = net profit ÷ total cost; cheap fixed power improves both terms.
The cost stack
| Cost | Share (typical) | Notes |
|---|---|---|
| Electricity | 60–80% | The decisive variable |
| Cooling | Part of power / capex | Hydro/immersion boosts efficiency |
| Maintenance | Ongoing | Repairs, parts, labor |
| Hardware | Upfront capex | Depreciates over ~5–7 yrs |
How the electricity rate drives ROI
| Rate | Power cost | Net profit |
|---|---|---|
| $0.0364 (hosted) | $149 | $690 |
| $0.0455 (hosted US) | $186 | $653 |
| $0.08 (low home) | $327 | $512 |
| $0.12 (home) | $490 | $348 |
Improving your ROI
Two levers move ROI most: a lower electricity rate and better efficiency (which cooling enables). Hosting delivers both — fixed power from $0.0364/kWh and hydro/immersion cooling — while folding maintenance into the package.

Frequently asked questions
What is the biggest cost in Bitcoin mining?
Electricity — typically 60–80% of ongoing costs, which is why the rate dominates ROI.
Does cooling really matter for cost?
Yes — good cooling sustains efficiency and hardware life, protecting both revenue and capex.
How is mining ROI calculated?
Net profit divided by total cost (hardware plus operating costs); break-even is hardware price divided by monthly net.
How does hosting lower costs?
It compresses electricity, cooling and maintenance into one low fixed rate from $0.0364/kWh.
