A standalone freezer can be a smart investment for bulk shopping and long-term food storage.
But since it runs 24/7, how much does it actually add to your electricity bill?
Let’s break down the real monthly and annual cost of running a freezer in 2026.
Quick Answer
Most modern freezers use:
• 150–400 kWh per year
At $0.16 per kWh:
👉 Annual cost: $24 – $65
👉 Monthly cost: $2 – $6
Average Electricity Cost per kWh by State (2026 U.S. Data)
Freezers are generally cheaper to run than refrigerators.
Freezer Cost by Type
| Freezer Type | kWh per Year | Cost per Year |
|---|---|---|
| Small chest (5–7 cu ft) | 150–250 | $24–$40 |
| Medium upright | 250–350 | $40–$55 |
| Large upright | 350–450 | $55–$72 |
| Old freezer (10+ yrs) | 500+ | $80+ |
Chest freezers are typically more energy efficient than upright models.
Why Chest Freezers Cost Less
Cold air sinks.
When you open a chest freezer, less cold air escapes compared to upright models.
That means:
• Less compressor cycling
• Lower energy use
• Better efficiency overall
Physics quietly saving you money.
Monthly Cost Example
Example:
300 kWh per year ÷ 12 ≈ 25 kWh per month
25 × $0.16 = $4 per month
That’s cheaper than most streaming subscriptions.
Freezer vs Refrigerator Cost
| Appliance | Annual Cost |
|---|---|
| Refrigerator | $50–$130 |
| Freezer | $25–$65 |
How Much Does It Cost to Run a Refrigerator Per Month?
Refrigerators cycle more frequently and often have automatic defrost systems that increase consumption.
Garage Freezer Warning
If your freezer sits in a hot garage:
• High ambient temperature
• More compressor work
• Increased electricity use
Energy consumption can increase 10–25% in extreme heat.
Is an Old Freezer Expensive?
Yes.
Freezers older than 10–15 years can use 2x the electricity of modern Energy Star models.
Replacing an inefficient unit can save $40–$80 per year.
FAQ
Does a freezer use a lot of electricity?
No. Modern freezers are relatively efficient.
How much does it cost per day?
Typically $0.07 – $0.18 per day.
Is it expensive to run a freezer in a garage?
It can be if temperatures are extreme.
Is a chest freezer cheaper than upright?
Yes. Chest freezers are generally more energy efficient.
Final Thoughts
Freezers are one of the more affordable 24/7 appliances in your home.
When energy-efficient and properly placed, they add only a small amount to your monthly bill.
Understanding real consumption numbers helps you decide whether keeping a second freezer is worth it.
