Use the energy cost calculator to estimate the electricity cost of running different appliances in no time.
E(kWh/day) = P(W) × t(h/day) / 1000(W/kW)
Cost($/day) = E(kWh/day) × Cost(cent/kWh) / 100(cent/$)
The most convenient and reliable way to calculate the energy cost is the power cost calculator. Because it just requires a few inputs and provides you with the precise cost of electricity.
Follow the below-mentioned steps to calculate the energy cost:
Let's go through an example of energy cost calculation for a household appliance, such as a refrigerator. Use the following information:
First, we will calculate the daily energy consumption:
Daily Energy Consumption = Power Consumption (in watts) × Daily Usage (in hours)
Daily Energy Consumption = 150 W × 12 hr = 1800 watt-hours (Wh) or 1.8 kilowatt-hours (kWh)
Now monthly energy consumption:
Monthly Energy Consumption = Daily energy consumption (kWh) × Number of days used per month= 1.8 kWh × 30 days = 54 kWh
Now perform power cost calculations:
Cost = Monthly Energy Consumption (kWh) × Cost per kWh
Cost = 54 kWh × $0.12/kWh = $6.48
Running a refrigerator that consumes 150 watts continuously for 12 hours a day for 30 days will cost you approximately $6.48 per month. If you don't want to perform the manual energy calculation, then simply use an energy consumption calculator. It will perform the calculation in a matter of seconds.
With this energy cost estimator, you can easily find the cost of running an electric appliance for a specific duration. Let’s see how it works:
