How Much Does It Cost to Run a Refrigerator in Maine? (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 $0.045 per hour, or about $10.80 per month at 8 hours a day in Maine. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (100 W) | $0.030 | $0.24 | $7.20 | $87.60 |
| Typical (150 W) | $0.045 | $0.36 | $10.80 | $131.40 |
| High (250 W) | $0.075 | $0.60 | $18.00 | $219.00 |
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
In Maine, with electricity at $0.30 per kWh (source: EIA Table 5.6.A, 2026-06), a typical refrigerator costs $0.045 per hour and about $131.40 per year at 8 hours a day. That is about 67% more than the national average for the US ($6.48 per month), because electricity in Maine costs $0.30 per kWh against $0.18 nationally. Each $1.00 of electricity buys roughly 22.2 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.
Would switching to a new efficient refrigerator pay for itself?

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.
