**Introduction:** The Lighting Cost Calculator is a handy tool to determine the electricity cost of your lighting setup. Whether you’re managing a household or a business, understanding the financial impact of your lighting choices is essential for budgeting and energy efficiency.

**Formula:** To calculate the electricity cost, we use the formula: Cost ($) = (Wattage (W) x Hours of Usage (hrs) x Electricity Rate ($/kWh)) / 1000

**How to Use:**

- Enter the wattage of your lighting source in watts (W).
- Input the number of hours you intend to use the lighting.
- Specify your electricity rate in dollars per kilowatt-hour ($/kWh).
- Click the “Calculate” button.

The calculator will instantly provide you with the estimated electricity cost.

**Example:** Suppose you have a 60-watt light bulb, plan to use it for 5 hours a day, and your electricity rate is $0.12/kWh. By using the calculator, you’ll find that the electricity cost is $0.36 for one day of usage.

**FAQs:**
