Frequently asked questions
Everything you need to know about mining profitability and how our calculator produces its numbers.
It estimates your profit from your share of the network hashrate: (your hashrate ÷ network hashrate) × blocks per day × block reward, multiplied by the live coin price, minus pool fees and electricity cost.
Prices are live and network parameters are current, but real profits depend on rising difficulty, pool luck, your uptime and your actual electricity rate. Treat the numbers as a well-informed estimate, not a guarantee.
Use your real $/kWh from your utility bill. It is the biggest factor in profitability: a rig that profits at $0.05/kWh can lose money at $0.15/kWh.
Mining pools typically charge 0.5%–3% of your rewards. Enter your pool's fee so the calculator subtracts it for a net figure.
Enter your hardware cost. The calculator divides it by your daily net profit to show how many days until the rig pays for itself.

Network hashrate, block reward and block time are refreshed from public chain explorers and mining statistics sites, and each figure in our configuration carries the date it was taken. Prices come from CoinGecko and update every minute while the calculator is open.
