Payback is how long the bitcoin a device earns takes to add up to its price. It leaves out electricity, which buys the heat: compare earnings per kWh with your electricity price to see whether mining alone covers it. It uses the average of the last 3 months, to 12 Nov 2026: bitcoin at $79,558, 969 EH/s on the network and 3.15 BTC a block, less a 2% pool fee, for the unit the best price buys, running all day. It cuts the block subsidy in half at each halving, the next around Apr 2028, and otherwise assumes those carry on unchanged, which they won't. Income at today's difficulty and price is about 17% below that average. Hashrate usually rises, though miners that stop paying after a halving may switch off, which leaves more for the rest. How we work it out. Earnings per kWh is what it earns for each kWh it uses, on the same averages and fee, before paying for the electricity and until the next halving.

Light grey marks aren't on sale at any store we checked. Turn this off to colour them all.
Higher is better for earnings per kWh and further left is better for payback, so the best devices sit towards the top-left corner. A log scale gives every ×10 the same space, so small and large devices both fit.
Circles are space heaters, diamonds water heaters, hexagons air filters, squares home miners, down triangles Bitaxe miners and up triangles industrial miners. Hover, tap or tab to a mark to see the device; click it, tap it again or press Enter to open it.

How loud is it?
68 devices with a published noise figure, placed next to everyday sounds.
Further left is quieter. Every 10 dB more sounds about twice as loud, and 3 dB is barely noticeable. The green zone is quiet enough for most bedrooms at night (35 dB or less; the WHO's night-time guide is 30 dB).
Each mark uses the loudest figure the maker or a seller gives. They rarely say how far away they measured or in which power mode, so treat these as rough. Light grey marks aren't on sale at any store we checked. Everyday sounds from the American Academy of Audiology's noise chart.
Prices are the cheapest offer we found for each device, converted to your currency at ECB rates. Stores are checked on different days, most recently 12 Nov 2026. Prices change often, so always check the store. Heat and noise figures come from makers and sellers. See how we compare.
