How Much Does It Cost to Run a Refrigerator in California? (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 $0.052 per hour, or about $12.60 per month at 8 hours a day in California. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (100 W) | $0.035 | $0.28 | $8.40 | $102.20 |
| Typical (150 W) | $0.052 | $0.42 | $12.60 | $153.30 |
| High (250 W) | $0.087 | $0.70 | $21.00 | $255.50 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 8 h/day ≈ 438 kWh per year.
In California, with electricity at $0.35 per kWh (source: EIA Table 5.6.A, 2026-06), a typical refrigerator costs $0.052 per hour and about $153.30 per year at 8 hours a day. That is about 94% more than the US national average of $6.48 per month, because electricity in California costs $0.35 per kWh against $0.18 nationally. Each $1.00 of electricity buys roughly 19.0 hours of use.
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.
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.
