Predict your energy expense. Calculate how much your appliances cost to run by day, month, and year.
An electricity cost calculator determines exactly how much an appliance affects your power bill over time. Everything plugged into your wall consumes watts. By taking that wattage, applying your estimated daily usage, and multiplying it by what your power company charges for a unified block of energy (the Kilowatt-hour), you can see the real financial impact of every device.
A Kilowatt (kW) is 1,000 Watts. Therefore, a Kilowatt-hour (kWh) simply means you have consumed 1,000 Watts of power continuously for exactly one hour. Your utility company charges you a flat fee for each block you use.
