FAQ
Frequently asked about the ROI calculator
How is mining profitability calculated?
Revenue comes from your rig's share of the network: (your hashrate / total network hashrate) × block reward × coin price × blocks per day. Subtract electricity cost (watts × hours × $/kWh ÷ 1000) and pool fees to get net profit. This calculator does the math in real time using live network data from MiningBoard's multi-source consensus engine.
What's a good payback period for a mining rig?
Under 12 months is solid. Under 6 months is excellent — you'll double your investment in the first year. Anything over 18 months carries significant risk because network difficulty and coin prices can shift. Use the sliders above to model different scenarios before committing capital.
How much does electricity cost matter?
It's the single biggest variable. At $0.05/kWh, most modern ASICs are highly profitable. At $0.15/kWh, only the most efficient machines break even. A $0.03 difference in your electricity rate can shift a rig's annual profit by $500–$2,000. If you're paying over $0.12/kWh, focus on the most efficient hardware.
Should I factor in difficulty increases?
Yes. Bitcoin's mining difficulty has historically grown 30–50% per year as new hardware enters the network. This means today's profit will gradually shrink unless coin prices rise to compensate. Use the difficulty growth slider to stress-test your investment against realistic scenarios.
