Household prices per Eurostat, 2. Halbjahr 2025, including all taxes and levies. Your own tariff may differ considerably; cheap switching offers often sit ten cents below. Just type yours in.
The break-even electricity price is the price per kilowatt-hour at which earnings exactly cover the power bill. Below it the machine earns, above it the machine burns money. In central Europe that is the number almost everything turns on.
Not included: connection, cooling, power-supply losses, downtime and maintenance. Water cooling adds the loop itself, hosting adds the slot fee. Network difficulty rises over the long run, which lowers earnings at the same hashrate; the payback figure uses today's values and is therefore on the optimistic side.
Canaan's Avalon Nano 3S delivers 6.0 TH/s at 140 watts, so 23.3 J/TH, which puts it in the bottom third: rank 79 of 85. At 140 watts it runs off an ordinary socket, which sets it apart from almost everything here. It is still loud. Its closest neighbours are the Antminer S19k Pro at 23.0 J/TH above and the WhatsMiner M50S+ at 24.0 J/TH below. The gap upwards is 0.3 J/TH; whether the premium for it is worth paying depends entirely on your electricity price. We hold no market reference for this model, so the price field above stays empty. Enter your own quote and payback appears beside it. Net per day and break-even do not need a price anyway.

If you do not like the numbers, you are not alone: at household prices almost none of these machines pay off in central Europe. If you still want to understand how mining works economically, you can play it through in the Coinovo app, with the same models and the same formulas, but without hardware and without a power bill.
