Understanding Your Appliance's Energy Use

Every appliance in your home contributes to your electricity bill. The amount of energy an appliance uses is measured in watts (W). The higher the wattage, the more power it requires. Our Power Consumption Calculator helps you translate this wattage into a real-world cost.

By understanding which devices are the most power-hungry, you can make informed decisions to reduce your energy usage and save money. This is particularly important with rising energy prices in the UK. Tools like this one from Calculator Site make it easy to see the financial impact of your daily habits.

Pro Tip: Check for Standby Power

Many modern electronics consume power even when they're turned off. This is known as "vampire" or "phantom" load. While usually only a few watts, this can add up to £50-£80 a year across all your devices. Unplugging chargers and devices when not in use is a simple way to save.

Common Appliance Wattages

To help you get started, here are some typical wattage ratings for common household appliances. Check your specific device for an accurate figure.

  • Kettle: 2200-3000W
  • Tumble Dryer: 2000-3000W
  • Washing Machine: 1800-2300W
  • Microwave: 800-1200W
  • Fridge/Freezer: 100-200W
  • 60" LED TV: 80-150W
  • Laptop Charger: 45-90W
  • Broadband Router: 7-10W
  • LED Light Bulb: 5-10W

As you can see, heating elements (like in kettles and dryers) use significantly more power than electronics. You can compare the running costs of different heating methods with our Gas Cost Calculator.
