Frequently Asked Questions

Check your utility bill — it shows the rate per kWh. In the US, the average is about $0.12/kWh, but it varies by state from $0.08 to $0.30+. Some areas have tiered or time-of-use rates.

Check the label on the appliance (usually on the back or bottom), the product manual, or search the model number online. Wattage may also be listed as "W" on the specifications.

This calculator assumes constant wattage and usage. Real appliances may cycle on/off (like refrigerators), have varying power draws, or be affected by tiered/time-of-use pricing.
