How to calculate appliance standby energy cost
This calculator estimates the annual cost of standby (phantom) power draw — electricity consumed by devices even when turned off or in standby mode — by multiplying standby wattage by an annual cost-per-watt figure.
How the calculation works
Annual standby cost = Standby watts × Annual cost per watt.
Example
5 watts of standby draw at an annual cost of $1.31 per watt (based on continuous use at a typical electricity rate): Annual cost = 5 × 1.31 = $6.57 per device.

Pro Tips for Appliance Standby Energy Cost
- Standby power draw varies significantly by device — game consoles, cable boxes, and older electronics often draw more standby power than newer, more efficient devices.
- A smart power strip that cuts power to standby devices when not in use can eliminate this cost entirely for devices you don't need always-on.
Common Appliance Standby Energy Cost Mistakes to Avoid
- Assuming all electronics have negligible standby draw — some devices (older cable boxes, certain game consoles) draw enough standby power to add up meaningfully over a year.
