How to Use the Second Fridge Electricity Cost Calculator
A second refrigerator or standalone freezer kept in a garage, basement, or utility room runs year-round, and its impact on your electric bill is often bigger than people expect. This calculator takes the unit's capacity, the season or location it sits in, and your electricity rate to estimate its average monthly energy use and cost.
Older or standalone units placed in a garage work harder in summer, since they have to overcome warmer ambient air to keep the interior cold — pushing energy use up 20-30% or more compared to spring or fall. In winter, cooler surrounding temperatures reduce the compressor's workload, so usage estimates are adjusted down accordingly.
Actual power draw varies by model and age, so the most accurate figure comes from the unit's EnergyGuide label, which lists estimated annual kWh — divide by 12 and multiply by your rate for a precise monthly cost. This calculator's result is an average estimate based on capacity alone.
Frequently Asked Questions
A second fridge or freezer kept in a garage or unheated space has to work harder to maintain its internal temperature when the surrounding air is hot. Running cost can increase 20-30% or more during summer months.
The most accurate method is to check the appliance's EnergyGuide label for its estimated annual kWh and multiply by your local electricity rate. This calculator gives an average estimate based on capacity.
