Same network, same bitcoin, same formula. What changes from one tier to the next is power draw, heat, and the break-even price in dollars per kWh. Collected 21/10/2026.
| Tier | Power | kWh / day | Gross / day | Net at $0.10/kWh |
|---|---|---|---|---|
| 1 TH/s | 0.02 kW | 0.5 kWh | $0.04 | -$0.01 |
| 10 TH/s | 0.20 kW | 4.8 kWh | $0.36 | -$0.12 |
| 50 TH/s | 1.00 kW | 24.0 kWh | $1.80 | -$0.60 |
| 100 TH/s | 2.00 kW | 48.0 kWh | $3.60 | -$1.20 |
| 500 TH/s | 10.00 kW | 240.0 kWh | $18.00 | -$6.00 |
Assumption: 20 W/TH, 144 blocks a day at 3.125 BTC, BTC price and hashrate collected 21/10/2026.
The break-even price does not depend on the tier: at 20 W/TH it is $0.0750/kWh for all five, because output and consumption scale in the same proportion. Changing tier changes the scale and the physical constraints, not the profitability per terahash.
Every tier shares the same output per terahash: it depends only on global hashrate and the bitcoin price. What differs is what each terahash costs to run. The break-even column sums it up: above it, you pay more for electricity than you produce in value; below it, the gap is your margin.
The US residential average was $0.1816/kWh in the first half of 2026 (EIA). Compare it with the break-even column: that gap alone explains why home mining rarely pays in the US, whatever the tier.
The smallest tier that means anything: 1 TH/s, one millionth of an exahash per second.
Gross output: $0.04/day · power draw: 0.5 kWh/day · break-even: $0.0750/kWh.
10 TH/s: a small hosting slot, or one twentieth of a recent ASIC.
Gross output: $0.36/day · power draw: 4.8 kWh/day · break-even: $0.0750/kWh.
50 TH/s: a quarter of a recent ASIC, 1 kW around the clock, and a real heat problem.
Gross output: $1.80/day · power draw: 24.0 kWh/day · break-even: $0.0750/kWh.
100 TH/s: the reference tier of this site, the one used on the country pages.
Gross output: $3.60/day · power draw: 48.0 kWh/day · break-even: $0.0750/kWh.
500 TH/s: 10 kW, a technical room, and a power bill that decides everything.
Gross output: $18.00/day · power draw: 240.0 kWh/day · break-even: $0.0750/kWh.
These pages cover the common tiers, but the calculator accepts any hashrate, any efficiency (W/TH) and any rate, with live network data.
