How Much Electricity Does a Refrigerator Use Per Month?
Refrigerators run throughout the day, but their compressor does not necessarily operate continuously. Monthly electricity use therefore depends on the refrigerator’s design, efficiency, age, temperature settings, room temperature, and condition.
Why refrigerator wattage can be misleading
A refrigerator may have a rated electrical input that is useful for understanding its peak or operating demand, but it cycles. Multiplying that wattage by 24 hours can therefore overestimate actual monthly consumption.
A better source: annual energy use
If the refrigerator has an energy label or manufacturer specification showing annual kWh consumption, that figure can be more useful for estimating typical yearly energy use. Divide annual kWh by 12 for a rough monthly estimate.
Example
Suppose a refrigerator is rated at 500 kWh per year. A simple average would be:
500 ÷ 12 = about 41.7 kWh per month.
At $0.16 per kWh, the energy portion would be approximately:
41.7 × $0.16 = about $6.67 per month.
This does not represent every household because actual usage varies.
What increases refrigerator energy use?
- High surrounding temperatures.
- Frequent door opening.
- Very low temperature settings.
- Poor door seals.
- Blocked airflow around the appliance.
- Older or less efficient designs.
How to measure actual use
If you want a measurement rather than an estimate, a suitable plug-in electricity meter can record energy consumption over a representative period. Follow the meter manufacturer’s safety instructions and do not use unsuitable meters for high-load appliances.
Estimate the cost
Once you know monthly kWh, multiply that number by your electricity rate. For more general appliance calculations, use our Electricity Cost Calculator.
Bottom line
For refrigerators, annual or measured kWh is generally more informative than assuming the compressor runs at its rated wattage for all 24 hours. Use the appliance’s energy information whenever it is available.
