40 watts / 1,000 × 12 hours × $.15/kWh = $.072 This electricity cost calculator works out how much electricity a particular electrical appliance will use and how much it will cost. This calculator is a great way of cutting back on your energy use and saving on your electricity bills
Check the nameplate on the appliance to determine the actual wattage required. * Appliances and tools with induction motors (marked * in tables) may require from 3 to 7 times the listed wattage when starting. The start-up load of the appliance or tool determines whether an inverter has the capability to power it.
To calculate the kWh used per day, start by finding the power consumption of the appliance in watts. This could be marked on the device, in the owner's manual, or in the technical specifications. Next, multiply the power in watts by the hours used per day, then divide by 1,000 to get the kilowatt-hours used.
Note: the average price of electricity is about 14 cents per kWh. Homes these days are equipped with many electrical appliances, and we use dozens, if not hundreds, of other devices, making it difficult to predict overall energy usage.
