How Much Does It Cost to Run a Refrigerator? (2026)
A refrigerator is plugged in all day, but the compressor only runs about a third of the time. The wattage figures here are the compressor draw, and the hours figure reflects typical compressor run time, not 24 hours.
A typical refrigerator (150 W) costs $0.028 per hour, or about $6.60 per month at 8 hours a day in the US. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 100 W | $0.018 | $0.15 | $4.40 | $53.55 |
| Typical 150 W | $0.028 | $0.22 | $6.60 | $80.33 |
| High 250 W | $0.046 | $0.37 | $11.00 | $133.88 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 8 h/day ≈ 438 kWh per year.
One hour of a refrigerator (0.15 kWh) is the same electricity as
- 3.3hours of a laptop
- 10phone charges
- 15hours of Wi-Fi
- 17hours of an LED bulb

How to lower the cost of running a refrigerator
- Set the fridge to 37 to 40 F (3 to 4 C) and the freezer to 0 F (-18 C). Colder settings waste power.
- Vacuum the coils at the back or underneath once a year. Dust makes the compressor work harder.
- Leave a gap for airflow behind and above the unit.
- A fridge from before 2000 can use twice the electricity of a new one. Replacement often pays for itself within a few years.
Is an efficient refrigerator worth it?
10 to 15 year old fridge-freezer (EU class F, or pre-2010 US model): about 650 kWh a year. Current A-rated or ENERGY STAR fridge-freezer: about 220 kWh. The difference is worth $78.86 a year in the US.
- Replacing one that still works pays back in 11.4 years.
- When yours needs replacing anyway, the extra cost of the efficient model pays back in 2.5 years.
Usage assumed: always on; the figures depend on the model, not on how you use it. Typical prices: $900.00 for the efficient model, $200.00 more than a basic one. Work it out with your own prices
Frequently asked questions
How many watts does a refrigerator use?
Most modern household fridges draw 100 to 250 watts while the compressor runs, averaging 1 to 2 kWh per day.
Does an empty fridge use more electricity?
Slightly. Food and drinks hold cold, so a full fridge recovers faster after the door opens.
Should I unplug my fridge when on vacation?
Only for trips longer than a month, and only if you empty and clean it first.
