100 TH/s: the reference tier of this site, the one used on the country pages.
Machine efficiency assumption: 20 W/TH (recent ASICs: 17 to 25 W/TH). BTC price and network hashrate pulled live.
Collected 21/10/2026. Sources: Binance (BTCUSDT), mempool.space (hashrate, difficulty), EIA Monthly Energy Review table 9.8 for the US residential rate.
At 20 W/TH, 100 TH/s draw 2 kW continuously, 48 kWh a day, the consumption of a whole household. It is the output of a mid-range recent ASIC, and the most common tier for a private buyer still hesitating.
At a hundred terahash the question is no longer "does it pay?" but "at what price per kWh does it pay?".
Remember the threshold: $0.0750/kWh. That is the highest electricity price at which 100 TH/s still break even at the current network level. Compare it with what you actually pay, taxes and delivery included, not the advertised rate.
Gross output = (100 TH/s ÷ network hashrate) × 450 BTC per day × bitcoin price. Power = 100 × 20 W × 24 h. No other variable: no promise of a rising BTC, no hidden yield. The network mines 144 blocks a day at 3.125 BTC since April 2024; the next halving cuts that reward in half.
Two things this calculation cannot predict: difficulty rises (same hashrate, less output every month) and the BTC price can fall. A pool or a hosting provider also takes a fee, not deducted here. The figure above is therefore an optimistic ceiling.
At the US residential average ($0.1816/kWh) the result is structurally negative: the electricity costs more than the bitcoin produced. The same machine plugged into $0.05/kWh, the rate a hosting site pays, turns positive. That gap, not the firmware settings, is the whole difference.

Figures collected 21/10/2026, 20 W/TH assumption. Details on the hashrate tiers page.
The calculator accepts any hashrate, any efficiency in W/TH and any electricity price: it recomputes with the live BTC price and difficulty. The country pages compare residential rates across Europe.
Nothing here is investment advice. Mining is an asset, not a guaranteed yield: difficulty rises, the BTC price can fall, hardware wears out. Commit only what you can lose entirely.
