The smallest tier that means anything: 1 TH/s, one millionth of an exahash per second.
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.
You do not buy 1 TH/s in a box. It is the share you get by splitting an ASIC, or by buying a slice of hosted hashrate. At 20 W/TH this tier draws 0.48 kWh a day, less than a fridge. That is exactly the problem: the revenue is smaller than the rounding on your power bill.
Against the whole network, 1 TH/s is a rounding error: daily output is counted in satoshis, not dollars.
Remember the threshold: $0.0750/kWh. That is the highest electricity price at which 1 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 = (1 TH/s ÷ network hashrate) × 450 BTC per day × bitcoin price. Power = 1 × 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 this level electricity forgives nothing. One cent of difference per kWh wipes out the entire output. 1 TH/s only makes sense if the kWh is billed at a professional rate.

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.
