GPU Electricity Cost Calculator
Estimate how much a GPU costs to run by wattage, hours per day, electricity rate, and monthly usage days.
Calculator inputs
Estimated running cost
Daily cost$0.75
Monthly cost$22.46
Yearly cost$273.31
Energy per year1,518.4 kWh
Assumes 520 W average load, 8 hours per day,30 days per month, and $0.18 per kWh.
Estimated peak765 W
Recommended PSU1,000 W
Method and assumptions
Electricity use is calculated as watts divided by 1000, multiplied by hours per day. Cost is energy multiplied by the electricity price per kWh. Real power draw varies by game, workload, undervolting, frame cap, cooling, and PSU efficiency.
