Cloud Mining vs Mining at Home — Full Cost Comparison (2026)

Methodology — What We Counted, What We Didn't

This model is a buyer's 12-month total cost of ownership (TCO) — not an earnings forecast. We price every dollar that leaves your pocket to hash at 200 TH/s from your spare room, then price every dollar that leaves your pocket to rent a comparable fleet slice on NoxHash for 12 months. Revenue is identical on both sides (same global difficulty, same BTC price), so it cancels out. What remains is cost — and cost is where the decision is actually made.

A fair note on hashrate parity: a single S21 produces 200 TH/s; the Pro Miner rental delivers 350 TH/s. The cloud plan therefore gives you more hashrate per dollar than the home rig. If you downsize the comparison to a Standard Miner (150 TH/s, $50/mo, $510 for 12 months at 15% off), cloud still wins on TCO everywhere except sub-$0.06/kWh — the math just shifts the margin.

Home Mining — Every Line Item for 12 Months

Below is the complete cost stack for running one Antminer S21 at home for a full year. Hardware pricing reflects April 2026 retail data: new units run about $1,700 on direct-from-reseller channels like CryptoMinerBros, with used units on Compass Mining's marketplace clearing around $750-800. We'll use $1,900 as a blended mid-point that includes PSU and shipping.

Everything above except electricity is regionally stable. The electricity row is what turns a $4,900 year into a $6,900 year — or, in a few lucky spots, a $3,000 year. We'll vary it across three regions in the side-by-side section below.

Cloud Mining — The Entire Cost Stack

The cloud side of the ledger is shorter by design — that's the whole product. NoxHash absorbs hardware, power, HVAC, network, pool fees, and parts into one monthly rental. You pay once; they operate. Here is the full 12-month stack for a Pro Miner (350 TH/s) on a 12-month term, which carries a 15% discount off the $100/month list price.

One row, one number. The operator's margin is buried inside that $1,020 — they pay $0.035/kWh industrial, you pay nothing per kWh, and they keep the spread. That's a fair trade when residential power in your region sits above $0.08/kWh, because you'd pay the spread plus the capex out of pocket anyway.

12-Month TCO Side-by-Side — Three Electricity Regions

Here is the full side-by-side across three representative residential rates: US $0.12/kWh (below the national EIA average of ~$0.18 to favor the home-miner case), EU $0.28/kWh (Eurostat first-half 2025 average), and Vietnam $0.10/kWh (upper residential tier). The cloud column stays at $1,040 in every row because data-center power is already baked in.

The punchline: at US residential $0.12/kWh, a home S21 costs 5.4× more than the cloud rental over 12 months. At EU $0.28/kWh, it's 10.7× more. Even at Vietnam's relatively cheap $0.10/kWh, home still costs 4.7× more than cloud. You would need an electricity rate well under $0.06/kWh for the home column to drop below the cloud column — which is exactly what we'll test next.

Break-Even Analysis — At What kWh Does Home Win?

Hold everything fixed except the electricity rate. The non-power home costs come out to about $1,440 over 12 months (hardware $1,900 + HVAC-proportional + internet $60 + pool $50 + maintenance $80 + noise box $200 − resale $850). Cloud is $1,040. That leaves $400 of power-cost headroom before home mining exceeds cloud cost.

Divide $400 by 2,520 kWh/month × 12 months = 30,240 annual kWh → $0.013 per kWh of headroom. But we also need to back out the 15% HVAC multiplier (~1.15× mining load), which means the residential rate itself needs to stay under about $0.011/kWh for pure cost parity — essentially impossible at retail.

That's the strict break-even. In practice, most home miners ignore the noise box, accept higher-cost cooling, or have a partner who will absorb some of the indirect cost. Relax the model — drop resale depreciation, ignore HVAC, skip the sound enclosure — and the break-even rate stretches up to ~$0.06/kWh. That's the number most honest miners quote, and it aligns with the hydro regions (Washington, Québec, Paraguay, parts of Iceland) where home mining actually makes economic sense today.

Important caveat: the "toss-up" at $0.06/kWh is only a toss-up because the cloud plan gives you 350 TH/s while the home rig gives 200 TH/s. Normalize to the same hashrate and the true cost-of-hash parity is closer to $0.05/kWh. Below that, buy the ASIC; above it, rent.

Hidden Costs Most Spreadsheets Miss

Standard mining calculators stop at "electricity + hardware". Real-world TCO keeps going. These are the quiet line items that push a home-mining project from "slightly positive" into "net loss" without the builder noticing until month six.

The Cambridge CBECI energy-consumption index tracks global mining power use, and the Cambridge Bitcoin Electricity Consumption Index confirms the broad residential-vs-industrial spread: professional operators consistently run at one-third to one-fifth the power cost of a home miner. That delta is not marketing — it's a structural input to the math above.
