Standby-power estimator

List the devices left on standby, with watts from their labels, and see what they cost a year. Context: EnergySage (Aug 2026) puts standby power at 5–10% of residential electricity use, up to about $183 a year in the US. Your own total below uses your watts and your rate — that is the figure that matters.

Estimate — verify on your bill. Check watts on the device label; do not guess.

Country — choose first. Rates differ by country; a US rate on a UK bill is a wrong number.

Your unit rate — from your bill, in $ per kWhUS average stored: 18.19 cents/kWh, Jan–Jul 2026 (US EIA). UK, Canada and Australia: no verified average stored — enter your own rate.
