Freezer Electricity Cost Calculator
Find out what your chest or upright freezer costs to run, using realistic compressor cycling.
Quick answer
A 120 W chest freezer whose compressor runs about 35% of the time uses roughly 1 kWh a day, 368 kWh a year — about $63 a year at $0.17/kWh. A hot garage pushes that up. Check your fridge too with the refrigerator calculator.

About the Freezer Electricity Cost calculator
A freezer runs 24 hours a day but its compressor only runs part of the time. Modern chest freezers commonly draw around 80–150 W while running and cycle on roughly a third of the time in a cool room — more in a hot garage or when the lid is opened often.
If your energy label gives kWh per year, that is the most reliable figure: divide by 365 for kWh per day. Chest freezers generally use less than upright models of the same size, because cold air stays in when the lid opens.
How to use it
- Enter the running wattage from the label.
- Keep 24 hours a day.
- Use about 35% average load in a cool room, 50% or more in a hot garage.
- Enter your price per kWh.
The formula
Yearly cost = Watts × 24 × Load ÷ 1000 × 365 × Price
- Or simply: label kWh per year × price per kWh.
Worked example
A 120 W chest freezer
- 120 W × 24 h × 35% = 1.0 kWh per day.
- About 368 kWh per year.
- At $0.17/kWh: about $62.54 a year.
Frequently asked questions
Does a full freezer use less electricity?
A well-filled freezer holds its temperature better when opened, so the compressor runs less. Fill gaps with bottles of water if it is half-empty.
Is a freezer in the garage more expensive to run?
In a hot garage, yes — the compressor works harder. Very cold garages can also cause problems for some models; check the manual’s temperature range.
Should I replace an old freezer?
Freezers over 15–20 years old can use far more energy than a new efficient model. Compare its measured kWh with the label of a new one.
