About this calculator
The Monthly Refrigerator Consumption Calculator is a practical tool to estimate the monthly electricity consumption of your refrigerator. It uses the formula P * 24 * 30 / 1000, where P is the refrigerator's power in watts, 24 is the number of hours in a day, and 30 is the number of days in a month. The result is the monthly consumption in kWh.
This calculator works based on the refrigerator's power, usually indicated on the appliance's energy efficiency label. Keep in mind that actual consumption may vary according to daily use and appliance efficiency.
When to use this calculator? It's useful for those who want to estimate the impact of refrigerator consumption on their electricity bill, plan their household budget, or compare the efficiency of different refrigerator models.
Remember that energy consumption also depends on other factors, such as ambient temperature, door opening frequency, and stored food quantity. Therefore, use the calculator as an estimate, not an exact value.
