Frequently Asked Questions
Watts ÷ 1000 × hours used = kWh consumed. Multiply kWh by your electricity rate ($/kWh) to get the cost for that period.
Many appliances (refrigerators, AC units) don't draw full power continuously — a compressor might only run 30-50% of the time even when the appliance is "on". Duty cycle adjusts for this so the estimate isn't inflated.
About $0.16-0.17 per kWh nationally as of recent EIA data, though rates vary significantly by state and utility — check your own bill for an exact figure.
