To understand the financial impact of your refrigerator’s energy consumption, you need to know your local electricity rate. Most utility companies charge per kilowatt-hour (kWh), and by following this simple formula, you can estimate your monthly cost:
Monthly Energy Cost = (Average Monthly kWh Consumption) x (Electricity Rate per kWh)
Let’s say your refrigerator consumes approximately 50 kWh per month, and your electricity rate is $0.12 per kWh. Your estimated monthly energy costs for your refrigerator would be:
50 kWh x $0.12/kWh = $6.00
This example illustrates just how manageable the cost can be, yet it varies based on the mentioned factors.
