Frequently Asked Questions
How is monthly kWh calculated?
kWh = (Watts × Hours per Day × Days per Month × Quantity) / 1000. This gives the total kilowatt-hours consumed in a month.
Where do I find the cost per kWh?
Your electricity bill shows the rate per kWh, often listed as the energy charge. In the United States, the average is around $0.13 per kWh, but rates vary by location and provider.
Can I use this for an entire home?
Yes. Add all major appliances and electronics to get a comprehensive estimate of your household electricity usage and cost.
Why does my actual bill differ?
Actual bills include taxes, fees, tiered pricing, and seasonal rate changes. This calculator estimates the energy portion only.
