Payback period calculator
Compare total cost per hash — hardware plus energy at your kWh rate — across a 1–36 month horizon. Switch to flat-rate mode for a fixed monthly fee; set a Monero price for daily revenue and profit.
Electricity cost & payback
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.
Prefilled with the live CoinGecko price — change it to model other scenarios.
Revenue uses the live P2Pool average payout of 0.0645 XMR per MH/s per day — the long-term fair share before luck and difficulty swings even out.
