How to Use the Watt Cost Calculator

Using the Watt Cost Calculator is simple and straightforward. Follow these steps to get accurate energy cost estimations:

Enter Device Wattage: Input the wattage of the device you want to calculate. You can find this value on the device label or user manual.
Specify Daily Usage Hours: Enter how many hours per day the device is used. This can be a fractional number like 1.5 hours.
Set Electricity Rate: Input your local electricity rate per kWh. The default is often around $0.13 per kWh, but you should use the exact rate from your electricity bill.
Select Days Per Week: Choose how many days per week the device is used. This allows for accurate weekly and monthly calculations.
Enter Number of Devices: If you have multiple devices with the same wattage, enter the total quantity.
Choose Device Efficiency Mode: Select Standard, Eco/Energy Saving, High Performance, or Standby mode. The efficiency mode adjusts the actual wattage automatically.
Calculate: Click the Calculate button to see your device’s energy consumption and estimated costs.
Reset (Optional): Use the Reset button to clear all values and start a new calculation.

Example Calculation

Let’s say you want to calculate the cost of running three 60W LED lights daily for 5 hours with an electricity rate of $0.15 per kWh in eco mode.

Device Wattage: 60W
Usage Hours: 5 hours/day
Electricity Rate: $0.15/kWh
Days Per Week: 7
Device Quantity: 3
Efficiency Mode: Eco

The calculator will provide:

Actual Wattage: 135 W (60W × 0.75 × 3 devices)
Daily Energy Consumption: 0.675 kWh
Weekly Energy Consumption: 4.725 kWh
Monthly Energy Consumption: 20.475 kWh
Daily Cost: $0.10
Weekly Cost: $0.71
Monthly Cost: $3.07
Annual Cost: $36.84

This shows how much running your lights costs over different timeframes, helping you plan and save money effectively.
