Home Bitcoin mining profitability in 2026 depends on one number: your electricity rate. Here's the exact math for the Antminer Home Series, Canaan Avalon Nano, and BitAxe — including daily profit tables, break-even calculations, and when mining beats just buying Bitcoin.
Bitcoin home mining profitability comes down to one number: your electricity rate in cents per kilowatt-hour. If you pay more than $0.12/kWh, most home miners are break-even at best. If you pay less than $0.08/kWh, home mining generates real income. Everything else — hashrate, difficulty, Bitcoin price — matters too, but electricity rate is the only variable you actually control.
This guide walks through the exact math for the three most popular home mining setups in 2026: the Antminer Home Series, the Canaan Avalon Nano, and the BitAxe Gamma. You'll know exactly what each machine earns per day at different electricity rates, what Bitcoin price you need to break even, and when home mining makes sense versus just buying Bitcoin directly.
Every mining profitability calculation starts here:
Daily revenue = (your hashrate in TH/s ÷ network hashrate in TH/s) × 144 blocks × 3.125 BTC × BTC price
Daily electricity cost = (power in watts ÷ 1,000) × 24 hours × electricity rate
Daily profit = Daily revenue − Daily electricity cost
At current network difficulty (around 108 trillion in early 2026) and Bitcoin near $95,000, the network earns roughly $0.000092 per TH/s per day in revenue.
So a 200 TH/s miner earns about $18.40/day in revenue before electricity.
Bitmain's home-focused Antminer Home Series produces 200 TH/s at 3,500 watts. It's designed to run quieter than industrial units but still requires good ventilation.
| Electricity Rate | Daily Cost | Daily Revenue | Daily Profit |
|---|---|---|---|
| $0.06/kWh | $5.04 | $18.40 | +$13.36 |
| $0.08/kWh | $6.72 | $18.40 | +$11.68 |
| $0.10/kWh | $8.40 | $18.40 | +$10.00 |
| $0.12/kWh | $10.08 | $18.40 | +$8.32 |
| $0.15/kWh | $12.60 | $18.40 | +$5.80 |
| $0.20/kWh | $16.80 | $18.40 | +$1.60 |
| $0.25/kWh | $21.00 | $18.40 | −$2.60 |
Break-even electricity rate: ~$0.22/kWh at current BTC prices. Monthly profit at $0.10/kWh: ~$300.
The Canaan Avalon Nano is the quietest miner in the directory — a desktop device that plugs into a standard outlet. It won't make you rich, but it's genuinely silent and cheap to run.
| Electricity Rate | Daily Cost | Daily Revenue | Daily Profit |
|---|---|---|---|
| $0.06/kWh | $0.20 | $0.37 | +$0.17 |
| $0.10/kWh | $0.34 | $0.37 | +$0.03 |
| $0.12/kWh | $0.40 | $0.37 | −$0.03 |
| $0.15/kWh | $0.50 | $0.37 | −$0.13 |
Break-even: ~$0.11/kWh. The Avalon Nano is a hobby miner — best for people who want to participate in mining without upfront cost or noise concerns.
The BitAxe Gamma is open-source, runs on a single ASIC chip, and draws almost no power.
At $0.10/kWh: Revenue $0.11/day, Electricity $0.04/day, Profit +$0.07/day (~$2/month)
The BitAxe won't pay your bills, but it's educational, open-source, and nearly free to operate. The BitAxe Ultra pushes to ~2 TH/s for slightly more output.
At $0.12/kWh, the Antminer Home Series costs $10.08/day in electricity. To cover that, you need:
Revenue = (200 ÷ 108,000,000) × 450 BTC/day × BTC price = $10.08
This solves to BTC price ≥ $24,300.
At current prices (~$95,000), you have a $70,700 safety margin before electricity costs exceed revenue. That cushion shrinks fast if difficulty doubles or BTC drops to $30k — both of which have happened in previous cycles.
The Antminer Home Series retails for $1,800-$2,500. At $300/month profit ($0.10/kWh), you break even on hardware in 6-8 months — before accounting for difficulty increases that reduce revenue over time.
A 3,500W miner generates 12,000 BTU/hour of heat. In summer, your AC works harder (adds to your effective electricity cost). In winter, it heats a room for free. This is why "heat mining" is increasingly popular.
Products like the Ember One Heater (an Antminer S21 Hydro in a heating enclosure), BitChimney, and BitHeater are purpose-built heat miners — you're paying for heat anyway, so the Bitcoin is a bonus.
Bitcoin difficulty adjusts every 2,016 blocks (~2 weeks) to maintain a 10-minute block time. As more hashrate joins the network, difficulty rises and your share of rewards shrinks. From 2024 to 2026, difficulty roughly doubled. Your $300/month profit today could be $150/month in a year if hashrate doubles again without a BTC price increase.
Upgrading to Braiins OS+ Firmware on compatible Antminer units reduces pool fees from 1-2% to 0% and enables autotuning — the firmware finds the optimal frequency for your specific chips, typically improving efficiency by 5-15%. On a miner earning $300/month, that's $15-45/month in free gains.
Good situation: Cheap electricity ($0.06-$0.10/kWh), cold climate where heat mining offsets costs, you own your home (noise isn't a problem), and you're committed to stacking sats over a 3-5 year horizon.
Bad situation: You pay $0.20+/kWh, live in an apartment, or expect mining to fund your lifestyle starting month one.
The honest comparison: At $0.12/kWh, 200 TH/s earns ~$8/day profit, or $2,920/year. The same $2,000 in Bitcoin, held for one year, earns $2,000 if BTC rises 10% — with zero effort, zero noise, and zero electricity cost. Mining beats buying when you have electricity cheap enough that the economics work independently of price appreciation.
| Use Case | Best Miner | Why |

Is home Bitcoin mining profitable in 2026? Yes, if your electricity is under $0.15/kWh. At $0.12/kWh with an Antminer Home Series, you net roughly $250-$300/month at current Bitcoin prices near $95,000.
What's the most important factor in mining profitability? Electricity rate. A miner with cheap power ($0.06/kWh) is profitable even if BTC drops 30%. A miner paying $0.22/kWh is unprofitable even at all-time highs.
How do I calculate my break-even electricity rate? Divide your daily revenue by your daily kWh consumption. If your miner earns $18/day and uses 84 kWh/day, your break-even rate is $0.214/kWh.
Do I need a mining pool? Yes. Solo mining at 200 TH/s means you'd find a block roughly once every 4,000 years. Join a pool (Braiins, Foundry USA, or AntPool) to receive small, regular payouts proportional to your hashrate. See our best Bitcoin mining pools guide.
What's the cheapest way to start home mining? The BitAxe Gamma costs around $80 and draws 15W. It won't earn much, but it's the lowest-risk entry point. For serious mining, check our best home Bitcoin miners guide.
