How to Use This Calculator

Enter the power consumption per rig in watts and the number of rigs.
Set your electricity rate in $/kWh.
Input hours running per day and cooling overhead percentage.
Review daily, monthly, and annual electricity cost and monthly cost per rig.
Use the monthly cost to determine minimum daily coin revenue needed for profitability.

How the result changes with Power per rig (W)

Power per rig (W)	Daily cost ($)	Monthly cost ($)
10,000	$27.60	$828.00
35,000	$96.60	$2,898.00
65,000	$179.40	$5,382.00
90,000	$248.40	$7,452.00

What each input means

Power per rig (W): Total wattage drawn by one mining rig at the wall (e.g., Antminer S19 Pro = 3250W).
Number of rigs: How many identical mining rigs you operate.
Electricity rate ($/kWh): Your cost per kilowatt-hour. US average is ~$0.10; industrial rates can be $0.04-$0.07.
Hours running per day: Hours per day the rigs are running. Most miners run 24/7.
Cooling overhead (%): Additional power for cooling (fans, AC). Typical data center PUE overhead is 10-20%.

What each result means

Total power draw (kW): Combined power draw of all rigs plus cooling, in kilowatts.
Daily energy (kWh): Total kilowatt-hours consumed per day.
Monthly energy (kWh): Total kilowatt-hours consumed per 30-day month.
Daily cost ($): Electricity cost per day.
Monthly cost ($): Electricity cost per 30-day month.
Annual cost ($): Projected electricity cost over 365 days.
Monthly cost per rig ($): Monthly electricity cost attributed to each rig.

How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
Power per rig (W) = 3250, Number of rigs = 1, Electricity rate ($/kWh) = 0.1, Hours running per day = 24 = 5 input(s) provided
Calculate Daily cost
Daily cost = dailyKwh * electricityRate
8.97 = $8.97
Calculate Monthly cost
Monthly cost = monthlyKwh * electricityRate
269.1 = $269.1
Calculate Total power draw
Total power draw = totalWattsAll / 1000
3.737 = 3.737
Calculate Daily energy
Daily energy = kW * hoursPerDay
89.7 = 89.7
