50 TH/s: a quarter of a recent ASIC, 1 kW around the clock, and a real heat problem.
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, 50 TH/s draw 1,000 W, 24 kWh a day. A kilowatt dissipated inside a home is a space heater that never turns off, noise included. In an apartment this stops being a profitability question and becomes a question about your neighbours.
Fifty terahash produce a daily fraction of bitcoin that reads in dollars, not tens of dollars: the entire margin is decided by the price of a kWh.
Remember the threshold: $0.0750/kWh. That is the highest electricity price at which 50 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 = (50 TH/s ÷ network hashrate) × 450 BTC per day × bitcoin price. Power = 50 × 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.
This is the tier where you understand why miners chase cheap power: at a residential rate, 50 TH/s often work for the utility rather than for you.

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.
