Step-by-Step Instructions: How to Use the Power Use Calculator

Follow these steps to calculate your monthly electricity usage and cost:

Step 1: Enter Device Wattage

Locate the power rating of your device (in watts). Most appliances have this listed on a label or in the manual. Input this number in the “Device Wattage (W)” field.

Step 2: Enter Daily Usage Hours

Estimate how many hours the device runs per day. Enter this value in “Hours Used Per Day”. For example, a TV used 4 hours daily would enter 4.

Step 3: Enter Days Used Per Month

Determine how many days per month you use the device and enter it in “Days Used Per Month”. If you use the appliance every day, type 30.

Step 4: Enter Electricity Cost

Input your local electricity cost per kWh in the “Electricity Cost ($/kWh)” field. This can be found on your electricity bill.

Step 5: Calculate Usage

Click the “Calculate Usage” button. A progress bar will animate as the calculation completes. Once done, the tool displays:

• Monthly Usage (kWh)
• Monthly Cost ($)

Step 6: Copy or Share Results

You can copy the results for personal records or share them directly via social media using the Copy and Share buttons.

Practical Example

Suppose you want to calculate the monthly cost of running a 1500W heater:

• Device Wattage: 1500 W
• Hours Used Per Day: 5
• Days Used Per Month: 30
• Electricity Cost: $0.12 per kWh

Calculation:

1. Monthly energy usage = 1500×5×301000=225 kWh\frac{1500 \times 5 \times 30}{1000} = 225 \text{ kWh}10001500×5×30​=225 kWh
2. Monthly cost = 225×0.12=$27.00225 \times 0.12 = \$27.00225×0.12=$27.00

Your result: 225 kWh per month, costing $27.00.

This simple calculation can help you compare devices and manage energy more efficiently.
