MicroBT's answer to the S21: 186 TH/s, 3441 W, 18.5 J/TH, with the power supply built into the chassis. The manual gives a 170-186 TH/s range depending on the batch, so a unit can arrive below the headline figure.

Same network, same day, same formula: only the efficiency in joules per terahash changes the bill. Sorted from the most to the least efficient.
Slightly less efficient than an S21 and usually cheaper to buy. On electricity alone the two land within a few percent of each other, which is the honest way to read the marketing: at this generation, one joule of difference barely moves the daily result.
Keep this number: $0.0803/kWh. Above it, one Whatsminer M60S burns more electricity than the bitcoin it produces, at the current network hashrate. Compare it with your real tariff, taxes and delivery included.
Gross output = (186 TH/s ÷ network hashrate) × 450 BTC a day × bitcoin price. Power = 3441 W × 24 h. Nothing else: no promised BTC rise, no hidden yield. The network mines 144 blocks a day at 3.125 BTC since April 2024.
Two things this cannot predict: difficulty keeps rising (same machine, less output every month) and the BTC price can fall. A worn unit also hashes below its rated figure.
Buying a machine is the visible cost, but the tariff decides the outcome. The alternative is to have the machine run where the kWh is billed at a professional rate: no room, no noise, no upfront hardware.
Referral code to enter by hand before any purchase: CALCULMINAGE, terms and method on the bonus page.
The calculator accepts any hashrate, any efficiency in W/TH and any tariff. The hashrate tiers answer the same question by power level, and 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.
