Refrigerator & Freezer Energy Cost Calculator

How to calculate refrigerator energy costs?

Costs depend on the total kWh consumed annually multiplied by the local price per kilowatt-hour.

Annual Cost = (Annual kWh) × (Rate per kWh)

Using the energy calculator: an example

Consider a 21 cu. ft. side-by-side refrigerator that uses 650 kWh per year.

Step-by-step calculation:

1. Identify annual kWh from the EnergyGuide label (e.g., 650 kWh).
2. Check your utility bill for the rate (e.g., $0.15/kWh).
3. Multiply 650 by 0.15 to get $97.50 per year.

Frequently Asked Questions

How much does an old refrigerator cost to run?

Older units built before 2000 can use 2-4 times more energy than modern Energy Star models, often costing over $200 per year.

Where can I find my energy consumption?

Look for the bright yellow EnergyGuide sticker inside or on the back of the appliance, which lists the estimated yearly electricity use in kWh.

Does the temperature setting affect cost?

Yes, setting your refrigerator below 37°F or freezer below 0°F forces the compressor to run more frequently, increasing energy use by up to 10%.
