# Energy Cost Calculator

Add the required inputs to this energy cost calculator and calculate the cost in seconds.

Typical appliance

Power consumption

Hours of use per day

h/day

1 kilowatt-hour (kWh) cost

### Solution:

First, we will calculate the daily energy consumption:

Daily Energy Consumption = Power Consumption (in watts) Ã— Daily Usage (in hours) Daily

Energy Consumption = 150 W Ã— 12 hr = 1800 watt-hours (Wh) or 1.8 kilowatt-hours (kWh)

Now monthly energy consumption:

Monthly Energy Consumption = Daily energy consumption (kWh) Ã— Number of days

used per month= 1.8 kWh Ã— 30 days = 54 kWh

Now perform power cost calculations:

Cost = Monthly Energy Consumption (kWh) Ã— Cost per kWh

Cost = 54 kWh Ã— $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.

## How Does Our Energy Cost Calculator Work?

With this energy cost estimator, you can easily find the cost of running an electric appliance for a specific duration. Letâ€™s see how it works:

What Do You Need to Enter?

• Typical Appliance: The specific appliances for which you want to know the energy cost
• Power Consumption: Amount of energy that the selected appliance consumes
• Hours of Use Per Day: The total hours the appliance runs in a day
• 1 Kilowatt-Hour (kWh) Cost: The cost of energy in your country

This is What You Will Get!

• Energy Cost Per Day: The daily cost of running the appliance
• Energy Cost Per Month: The cost that you will have to pay after running it for a month
• Cost of Energy Per Year: This is the annual cost of energy that your appliance is consuming in a year

Through this power cost calculator, you can calculate the energy consumed by the appliances of your home, offices, or any commercial unit and can make the right decision regarding the use of energy.
