How to Calculate Your Appliance Energy Usage
Understanding how to calculate electricity usage helps you identify the biggest opportunities for savings.
Step-by-Step Calculation Method
- Find the Wattage: Check the appliance label or manual
- Calculate Daily Usage: Watts × Hours Used ÷ 1,000 = Daily kWh
- Calculate Monthly Usage: Daily kWh × 30 = Monthly kWh
- Calculate Cost: Monthly kWh × Your Electricity Rate = Monthly Cost
Example Calculation
For a 1,500-watt space heater used 6 hours daily:
- Daily Usage: 1,500W × 6 hours ÷ 1,000 = 9 kWh
- Monthly Usage: 9 kWh × 30 = 270 kWh
- Monthly Cost: 270 kWh × $0.17 = $45.90
