Operating economics
Mining revenue is not hardware payback: inspect the electricity scenario
A device can produce revenue and still lose money after electricity. It can also have a small positive operating surplus while leaving almost all of its purchase cost unrecovered. The operating scenario keeps those outcomes separate.
Use measured wall power and an explicit revenue assumption
The current calculator does not derive yield from a network, coin or device name. Gross revenue per full-uptime day is an input supplied by you. Retain its source and date, and keep optimistic, base and adverse cases distinct.
At 3,000 watts and full uptime, running energy is 3 kW × 24 hours, or 72 kWh per day. At an entered 0.10 per kWh, the electricity bill is 7.20 before other costs. Cooling, time tariffs and standby power can make a real installation different.
Follow the default scenario through daily rounding
The illustrative defaults use gross revenue of USD 8 at full uptime, 95% uptime, a 2% revenue fee, 3,000 W, USD 0.10 per kWh and USD 0.50 other daily cost. Net revenue is rounded to USD 7.45 per calendar day. Running energy is 68.4 kWh, costing USD 6.84.
Daily operating surplus is therefore USD 0.11. Over 365 flat-assumption days, that is USD 40.15. Subtracting a USD 3,000 equipment outlay leaves a scenario cash shortfall of USD 2,959.85. A positive operating line is not evidence that the hardware was a profitable investment.
Understand what the recovery number assumes
The reported flat-scenario recovery divides equipment outlay by a positive daily operating surplus. If surplus is zero or negative, it reports no recovery at those assumptions. A very long result is not a forecast that the machine will remain useful until that date.
Network difficulty, rewards, token price, fees, availability, repairs, electricity contracts, tax and resale can change. Uptime scales running electricity and revenue together in this simplified model; actual payout and power behavior may differ.
Stress-test before treating a number as a decision
Try a lower gross-revenue input, a higher energy price and a no-resale case. Record fixed costs and qualified site-work quotes separately. Do not treat a device specification, manufacturer marketing example or old network observation as current realized cash income.
The tool is an editable arithmetic scenario. It is not a network-yield feed, investment recommendation, electrical design or promise of profit.
