ASIC Hosting Calculator
Turn watts and a $/kWh rate into a real margin: power cost, host fees, uptime and the payback of the machine itself.

If you own the miner, hosting is a power rate plus fees. Enter your machine (or pick a preset), the host's $/kWh, fees and uptime - get the true net margin, the break-even coin price and a payback estimate that includes rising difficulty.
Advanced assumptions
Results recalculate as you type. Power is billed around the clock even when the rig is offline.

Power is the whole game
Newer ASICs win on efficiency (J/TH): at a fixed power rate, a 13.5 J/TH machine (Antminer S21 XP) leaves a much bigger margin than a 21 J/TH one. Most hosting contracts bill per kWh with a minimum consumption, so an idle machine still costs money - which is why uptime applies to revenue only in the math. Before signing, check the uptime SLA and what happens when the rig becomes unprofitable - the honest hosts let you power it down. Scrypt miners earn LTC and DOGE together (merged mining); pick the Scrypt coin to model both.
Questions about hosting maths
Why does uptime matter so much?
Power is billed around the clock while revenue follows uptime. A host with 90% uptime removes a tenth of the income without removing the power bill, so the margin collapses faster than the headline rate suggests.
Is a cheap electricity rate always better?
No. Curtailment rules, minimum terms and retrieval terms decide whether you still get the machine back. The rate is only one line of the contract.
How is payback calculated?
By simulating the term month by month with growing difficulty, so a machine that only pays back under a flat difficulty model shows as never paying back.
