Chest Freezer Running Cost Calculator
Chest freezers retain cold air well, but ambient temperature and insulation still matter.
Direct answer: The editable 120 W preset at 30% compressor duty uses 0.86 kWh per day and costs about $4.78 per 30-day month or $58.15 per year. Use exact-model annual kWh when available.

kW × effective runtime × rate. Effective runtime = hours/day × duty cycle.
Baseline vs scenario
Compare two annual energy-use estimates.
Old vs new appliance payback
Use annual kWh for both models. Leave rebate at $0 unless you have a confirmed amount.
Simple payback = net upfront cost ÷ annual electricity-cost savings. Excludes financing, maintenance, rate changes and time value of money.

Use the label, then account for placement
A chest freezer cycles its compressor rather than drawing nameplate watts continuously. EnergyGuide annual kWh is the clearest starting point for the exact model; runtime mode is an editable fallback.
What changes freezer electricity use
- Capacity and insulation vary by model and size.
- High garage or utility-room temperatures can increase compressor duty cycle.
- Lid openings, gasket condition, frost, and ventilation affect runtime.
- Seasonal ambient temperature can make one annual duty estimate imperfect.
Enter annual kWh for a label-based monthly and yearly estimate, or adjust watts and duty cycle for measured seasonal scenarios.
Chest freezer cost quick answers
How much does a chest freezer cost per month?
The current runtime preset is about $4.78 per 30-day month at the U.S. average rate.
How much does a chest freezer cost per year?
The current preset is about $58.15 per year. Exact-model annual kWh multiplied by your rate is preferable.
Should I use annual kWh or wattage?
Use EnergyGuide annual kWh when available because compressor cycling is already represented. Wattage plus duty cycle is a fallback.
Does garage placement matter?
Yes. Ambient temperature can change compressor runtime, and not every model is designed for the same garage temperature range.

Make the estimate more accurate
- Use EnergyGuide annual kWh when available.
- Keep the lid gasket clean.
- Adjust duty cycle by season for garage placement.
Presets are estimates. Use your model label, an EnergyGuide annual-kWh figure or a safe meter reading when available. Compare old and new appliance payback.
