Your refrigerator runs 24 hours a day, 365 days a year.
But does that mean it’s one of the biggest electricity users in your home?
Let’s calculate the real monthly and annual cost of running a refrigerator.
Quick Answer
Modern refrigerators use:
• 300–800 kWh per year
• 25–65 kWh per month
At $0.16 per kWh:
👉 Monthly cost: $4 – $11
👉 Annual cost: $50 – $130
Average Electricity Cost per kWh by State (2026 U.S. Data)
Refrigerator Electricity Cost by Type
| Refrigerator Type | kWh per Year | Cost per Year |
|---|---|---|
| Energy Star (modern) | 300–400 | $50–$65 |
| Standard modern | 400–600 | $65–$95 |
| Older fridge (10+ years) | 600–800 | $95–$130 |
Newer models are dramatically more efficient.
Monthly Cost Breakdown
Example:
500 kWh per year ÷ 12 ≈ 42 kWh per month
42 × $0.16 = $6.72 per month
Most households spend less than $10 monthly on refrigeration.
Is a Refrigerator Expensive to Run?
Compared to:
• Air conditioners
• Electric dryers
• Space heaters
A refrigerator is moderate, not extreme.

Cooling systems consume far more energy seasonally.
Does Size Matter?
Yes.
Large French-door refrigerators consume more energy than compact models.
Garage refrigerators often cost more because:
• Higher ambient temperatures
• Lower efficiency in extreme heat
What About Freezers?
Standalone freezers typically add:
150–400 kWh per year
Cost: $25–$65 annually.
How Much Does It Cost to Run a Freezer?
FAQ
Does a refrigerator use a lot of electricity?
It runs continuously, but modern models are efficient.
How much does it cost per day?
Typically $0.15 – $0.30 per day.
Is it cheaper to unplug a second fridge?
Yes. Older spare fridges can cost $100+ per year.
Are Energy Star refrigerators worth it?
Yes. They reduce annual electricity use significantly.
Final Thoughts
Refrigerators are essential and relatively affordable to operate.
Replacing an old unit can cut electricity costs by 30–50%.
Understanding real usage numbers helps identify where true energy savings are possible.
