Break-even calculator

Find your break-even

Cheap hardware wins when power is nearly free; efficient hardware wins when you pay per kilowatt-hour. Plug in your electricity price to see when that flips — switch to flat-rate mode if you pay a fixed monthly fee, and adjust the prefilled Monero price to see daily revenue and profit at the current P2Pool payout per hash.

Electricity cost & break-even

Enter what you pay for power and what your outlet can actually deliver. The table re-ranks every build by total cost per kilohash — hardware plus electricity over your time horizon — and shows when efficient hardware pays for itself.

Revenue uses the live P2Pool average payout of 0.0718 XMR per MH/s per day — the long-term fair share before luck and difficulty swings even out.

When does efficiency pay off?

Electricity above ~$0.48/kWh: the AMD Ryzen 9 5950X becomes cheaper per kilohash than the Dual Intel Xeon E5-2699 v3 (LGA 2011-3) within 12 months. Below that, the cheaper rig wins.
