Calculate your actual running cost
Running this freezer for 8 hours a day, 7 days a week uses about 29.1 kWh each month.
Quick answer
How much does a freezer cost to run?
A 120 W freezer used for 8 hours a day, 7 days a week, consumes about 29.1 kWh per month. At $0.30 per kWh, that is approximately $8.74 per month. Replace these example figures with the wattage and electricity rate from your appliance and bill.
What changes the real running cost?
A freezer is plugged in all day, but the compressor cycles on and off. Room temperature, door openings, frost build-up, seal condition, and set temperature all affect its daily kWh.
If the energy label gives annual kWh, divide it by 365 for daily kWh. Otherwise, estimate effective compressor hours rather than entering 24 hours at full rated watts.
Assumptions used in this example
This page starts with 120 watts, 8 hours of use per day, and 7 days per week. Those defaults are only a practical starting point. Replace them with the number on your product label, energy label, smart plug, or electricity bill.
Example freezer costs
These examples use 120 W for 8 hours a day and 7 days per week.
| Electricity rate | Per hour | Per month | Per year |
|---|---|---|---|
| $0.15 / kWh | $0.02 | $4.37 | $52.42 |
| $0.25 / kWh | $0.03 | $7.28 | $87.36 |
| $0.35 / kWh | $0.04 | $10.19 | $122.30 |
Ways to reduce the cost
Start with changes that reduce active runtime without compromising safety or the job the appliance needs to do.
- Keep door seals clean and tight.
- Defrost manual-defrost models before ice build-up gets heavy.
- Leave ventilation space around the freezer.
Estimate only. Actual consumption varies by model, setting, condition, temperature, duty cycle, and tariff. Use a plug-in meter or energy-label figure when accuracy matters.
FAQ
Freezer running cost questions
How do I calculate freezer running cost?
Divide the watts by 1,000 to get kilowatts, multiply by the hours used, then multiply by your electricity price per kWh. This page pre-fills 120 W, 8 hours per day, and 7 days per week as a starting example.
How much does a freezer cost per hour?
At 120 W and $0.30 per kWh, the example cost is about $0.04 per hour while it is actively using that power. Change the rate field to match your own bill.
Why might my real freezer cost be different?
If the energy label gives annual kWh, divide it by 365 for daily kWh. Otherwise, estimate effective compressor hours rather than entering 24 hours at full rated watts.
Should I use rated watts or measured watts?
Rated watts are useful for a quick estimate, but measured wall power or an energy-label kWh figure is usually more accurate because many appliances cycle on and off or change power during use.
Does the calculator include standing charges, taxes, or demand charges?
No. The calculator estimates usage cost from kWh only. If your bill includes standing charges, taxes, delivery fees, or demand charges, add those separately.
Can I share my result?
Yes. Use the share or copy button after entering your wattage, hours, days, rate, and currency. The page stores those inputs in the URL so you can revisit the same estimate.
