For example, if your refrigerator is rated at 200 watts:
Daily Consumption = 200 watts × 24 hours × 0.80 = 3,840 watt-hours, or 3.84 kWh
Step 3: Monthly Consumption
To get your monthly consumption, multiply the daily consumption by the number of days in a month:
Monthly Consumption = Daily Consumption × 30
Continuing from our previous example:
Monthly Consumption = 3.84 kWh × 30 = 115.2 kWh
Step 4: Cost Calculation
To calculate your cost, multiply your monthly cost by the price per kWh from your electricity bill. For instance, if your electricity rate is $0.12 per kWh:
Monthly Cost = Monthly Consumption × Cost per kWh
Monthly Cost = 115.2 kWh × $0.12 = $13.84
