Common questions
How do I calculate my electricity cost?
Multiply the device's wattage by hours of use, then divide by 1,000 to get kWh. Multiply by your electricity rate. For example, a 100W bulb for 10 hours = 1 kWh; at $0.12/kWh = $0.12.
How much does it cost to run an air conditioner?
A typical window AC uses 500–1,500 watts. At 1,000W running 8 hours/day at $0.12/kWh, that is about $0.96/day or ~$29/month. Central AC costs vary widely by unit size and climate.
