How the chest freezer estimate works
The calculator converts watts to kilowatts, multiplies by effective runtime, and then applies the electricity price. With the starting inputs, this chest freezer uses about 24.0 kWh per month.
Garage heat, age, size, thermostat setting, frost, and lid openings can shift annual kWh.
How runtime changes the estimate
These scenarios assume the device draws the full starting wattage for the entire runtime. Cycling and variable-speed equipment should use effective runtime or measured kWh.
How much does it cost to run a chest freezer?
A chest freezer is plugged in all day but its compressor cycles. The EnergyGuide annual kWh estimate or a multi-day plug-in meter reading is more accurate than multiplying compressor wattage by 24 hours.
Garage temperature, freezer age, size, frost, gasket condition, temperature setting, and lid openings can make the same model use more or less electricity across the year.
Chest freezer operating-cost scenarios
These scenarios convert compressor wattage into equivalent daily runtime. They are examples, not efficiency ratings for a specific freezer. Costs use the latest 2026-05 U.S. residential average of 18.44¢/kWh.
Use annual kWh for the best freezer estimate
Divide the EnergyGuide annual kWh figure by 12 for a monthly average, then multiply by your electricity price. A meter reading over warm and cool periods is stronger when the freezer sits in an unconditioned garage.
Before replacing a working freezer, compare measured annual cost with the purchase price and rated energy of a replacement. Gasket repair, defrosting, and ventilation may correct avoidable runtime first.

Practical ways to reduce cost
- Keep the gasket clean and sealing.
- Defrost excessive ice buildup.
- Use the EnergyGuide annual kWh value when available.

Frequently asked questions
How much electricity does a chest freezer use?
Using a 100-watt starting input for 8 hours per day and 30 days per month produces an estimate of 24.0 kWh per month. Actual use can differ because equipment may cycle or change power.
How much does it cost to run a chest freezer each month?
At the latest 2026-05 U.S. residential average price of 18.44 cents per kWh, the starting estimate is $4.43 per month. Replace the inputs with your own numbers for a personal estimate.
What number should I use for the electricity price?
Divide the total electric charges on your latest bill by the total kWh used for an all-in price. State averages are useful for comparison but are not utility-specific rates.
