💡 About This Tool

Stop guessing about your electricity bill. Whether you’re curious about a high-end gaming PC or comparing a space heater to central AC, this tool helps you master your energy consumption. We’ve included presets for common household devices so you can start identifying potential savings immediately.

📘 Pro Tips

  • Use Presets: Select items like "Air Conditioner" or "Hair Dryer" from the dropdown to automatically fill in typical wattage.
  • Toggle Units: Most small electronics use Watts (W), while heavy appliances use Kilowatts (kW). You can switch between them with one click.
  • Input Your Local Rate: For the most accurate results, check your latest utility bill for your specific "Rate per kWh."
  • Calculate 24/7 Impact: For "always-on" devices like routers or refrigerators, set daily usage to 24 hours to see their total annual cost.

🧐 Frequently Asked Questions

Does this match my utility bill exactly? This tool estimates consumption based on your inputs. Your actual bill includes fixed base fees, taxes, and potential tiered pricing (where rates increase as you use more power).

Where can I find the wattage of my device? Look for a sticker on the back or bottom of the appliance labeled "Rated Power" or "Input." It is usually measured in Watts (W).

Why does my refrigerator cost seem high? Refrigerators don't run at full power 24/7; they cycle on and off. Our "24h average" preset accounts for this cycle, but your actual costs will vary based on your kitchen's temperature and how often the door is opened.

📚 Power vs. Energy: W vs. Wh

Understanding the difference between Watts (W) and Watt-hours (Wh) is key to managing your bill: - Watts measure power (the rate of energy use at this exact moment). - Watt-hours measure energy (the total power used over time).

Your utility company charges you for Kilowatt-hours (kWh)—that’s 1,000 Watts used for one hour. Switching to LED bulbs (9W vs. 60W for incandescent) is one of the fastest ways to slash your kWh usage and lower your bill.
