Electric Usage Calculator

How much does this cost on my utility bill?

Use this Energy Usage Calculator to see just how much a specific appliance or device costs to operate. If you are unsure, look for the examples of average watt requirements below the calculator.

To find wattage the formula is

amps (A) x volts (V) = watts (W)

Energy Usage Calculator

Multi-Item Electric Usage Calculator

The multi-item calculator uses average wattage for all the items listed. Variables like brand, manufacture year, style, etc. can affect the actual amount of watts for your specific device. For more specific usage analysis, please use the one-time calculator above.

Wattage varies for HVAC items like furnaces and air-conditioners. We have chosen to use “running watts” for the calculation. This is the amount of watts a system uses when running. Not when it initially turns on (which tends to be more for a brief period).
