Electricity Cost Calculator

October 1st, 2011

Using this tool, you can calculate the approximate cost of running an appliance from its amp or wattage requirement. Below, specify one of the following:

Amps and Volts (volts is typically 120 in North America, and 240 elsewhere.. See this).
Watts (Setting this value will reset amps and volts)

After this, enter your daily use for this item in hours, and the cost per kWh (in the Cost/kWh box). This page will calculate the kWh and the Cost/Day value.

Please note the provided value on this page ($0.1013) is the current Chicagoland electricity rate/kWh. This is in addition to any service charges and fees, and should be used as an estimation tool only.

Calculate that data!
