How Much Electricity Does Your Home Really Use? A Simple Guide
Date: August 3, 2025
Have you ever looked at your electric bill and wondered where all that energy went? You're not alone. Many homeowners don’t actually know how much electricity their appliances use—or which ones are silently racking up costs.
Understanding Kilowatt-Hours (kWh)
Electricity is measured in kilowatt-hours (kWh). If an appliance uses 1,000 watts (1 kilowatt) for one hour, it consumes 1 kWh of electricity. Your utility company charges you based on the total kWh you use each month.
How to Calculate Appliance Usage
Here’s a simple formula:
Wattage × Hours used per day ÷ 1,000 = Daily kWh
Multiply the result by 30 to get a monthly estimate.
Example:
A 1500W space heater used 5 hours/day:
- 1500 × 5 ÷ 1000 = 7.5 kWh/day
- 7.5 × 30 = 225 kWh/month
Common Household Appliance Costs
- Air Conditioner (2,000W): ~60 kWh/month (moderate use)
- Refrigerator (150W): ~36 kWh/month
- Washing Machine (500W): ~10–15 kWh/month
- Television (100W): ~10–20 kWh/month
- Wi-Fi Router (10W): ~7 kWh/month
Why This Matters
When you understand usage, you can make better choices. For example, unplugging devices that use standby power (like TVs or game consoles), or replacing old appliances with energy-efficient models, can make a noticeable impact.
How to Monitor Your Electricity Usage
- Smart Plugs: These plug between your wall socket and appliance and give you real-time usage stats via an app.
- Home Energy Monitors: Devices like Sense or Emporia track your whole house usage.
- Manual Method: Record your meter readings at the same time daily to calculate usage changes.
