How much energy do your appliances use?
This calculator estimates the cost to run your appliances each month, we hope it offers insight into where you can save. Some appliances use more watts hourly, but if not used often, the cost can be relatively low compared to lower watt appliances that run longer. Give it a go.
Appliance icons shown from highest to lowest watt usage per hour.

Appliances are typically labeled with hourly watt usage. Locate the information and calculate the monthly energy cost below.
Some appliances are labled by Amps (A), Milliamps (mA, 1mA=0.001A) or BTU's instead of wattage. Use the formulas below to calculate the appliance Watts.
Amps x Volts = Watts
BTU x 0.293 = Watts
Beware of Energy Vampires
Many appliances -- TV's, computers and device chargers in particular -- are continually sucking power from the grid, even when they are turned off. The average U.S. home spends $100-200 per year to power devices while they are off (or in standby mode). One way to slay a "vampire" load is to use a power strip as a central turn-off point for multiple appliances. Use a power strip for your computer and peripheral equipment and another for your home electronics (TV, DVD, stereo, gaming). Unplug your chargers: they are drawing energy even when they aren't charging. Slay the energy vampires in your home!
