Cost of Electricity (TC): The calculator returns the cost in U.S. dollars. However, this can be automatically converted to other currency units via the pull-down menu.
The Cost of Electricity calculator uses the average power usage, duration of usage and cost per power unit to compute the cost of electricity. The formula for the Cost of Electricity is:
`TC = P * T * UC`
where:
This calculator answers questions like the following:
Note: The currency conversions in vCalc are updated every five minutes. Using this, you can enter the power rates in the local currency, and see what that costs in your currency (e.g. electricity costs X per kilowatt hour in Great Britain Pounds (GBP), but what does that power cost equate to in Japanese Yen.)
Utility cost vary by provider and location. Check your monthly power bill to see the rate that applies to you. A recent survey indicated that the average rate for a kiloWatt-hour in the United States was 11.88 cent per kWh (2012)
The Don Rowe website provides an estimated power (watts) level for different appliances, tools, pumps and air conditioners HERE.
