Calculate your actual running cost
Running this fridge freezer for 8 hours a day, 7 days a week uses about 36.4 kWh each month.
Quick answer
How much does a fridge freezer cost to run?
A 150 W fridge freezer used for 8 hours a day, 7 days a week, consumes about 36.4 kWh per month. At $0.30 per kWh, that is approximately $10.92 per month. Replace these example figures with the wattage and electricity rate from your appliance and bill.
What changes the real running cost?
A fridge is connected all day but its compressor cycles. Effective daily runtime is therefore much lower than 24 hours and varies with room temperature and door openings.
If the energy label gives annual kWh, divide that figure by 365 and use the calculator's energy result as a comparison.
Example fridge freezer costs
These examples use 150 W for 8 hours a day and 7 days per week.
| Electricity rate | Per hour | Per month | Per year |
|---|---|---|---|
| $0.15 / kWh | $0.02 | $5.46 | $65.52 |
| $0.25 / kWh | $0.04 | $9.10 | $109.20 |
| $0.35 / kWh | $0.05 | $12.74 | $152.88 |
Ways to reduce the cost
Start with changes that reduce active runtime without compromising safety or the job the appliance needs to do.
- Leave ventilation space around the appliance.
- Check that door seals close firmly.
- Keep the temperature at the recommended setting.
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.
