Practical Example of Using the Calculator

Let’s say you want to calculate the cost of using a 60W LED lamp that runs 5 hours per day, every day of the month, with an electricity rate of $0.15 per kWh.

  1. Device wattage: 60
  2. Hours per day: 5
  3. Days per month: 30
  4. Rate per kWh: 0.15

Calculation: kWh per month=60×5×301000=9 kWh\text{kWh per month} = \frac{60 \times 5 \times 30}{1000} = 9 \text{ kWh}kWh per month=100060×5×30​=9 kWh Monthly cost=9×0.15=1.35 USD\text{Monthly cost} = 9 \times 0.15 = 1.35 \text{ USD}Monthly cost=9×0.15=1.35 USD Yearly cost=1.35×12=16.20 USD\text{Yearly cost} = 1.35 \times 12 = 16.20 \text{ USD}Yearly cost=1.35×12=16.20 USD

The calculator instantly shows that this lamp costs $1.35 per month or $16.20 per year to run, helping you make informed decisions about energy consumption.
