How Much Does a Garage Refrigerator Cost to Run? Is a Second Fridge Worth It?
That old refrigerator in your garage may seem almost free to keep.
After all, you already own it.
But a second refrigerator runs day and night, and an older model can quietly add to your electricity bill year after year.
The real question is not simply how much a garage refrigerator costs to run.
It is whether you should keep it, replace it with a more efficient refrigerator, or remove it completely.
The calculator below compares all three choices over five and 10 years.
A garage refrigerator can add a meaningful recurring expense because it operates continuously. ENERGY STAR says refrigerators more than 15 years old could cost about $95 per year to run and specifically recommends considering replacement or recycling of an old second refrigerator. Your actual cost depends on the refrigerator's annual kWh use and your electricity rate.
Garage Refrigerator Cost Calculator
For the most accurate result, find the refrigerator's annual energy consumption on its EnergyGuide label, product specifications, or manufacturer information.
If you are considering a replacement, enter the new refrigerator's annual kWh rating and purchase cost as well.

How Much Does a Garage Refrigerator Cost to Run?
The basic calculation is straightforward:
Annual Electricity Cost = Annual kWh × Electricity Rate
For example, suppose an older second refrigerator uses 600 kWh per year and electricity costs 18.44 cents per kWh.
The calculation would be:
600 × $0.1844 = $110.64 per year
Over five years, that becomes approximately:
$553.20
Over 10 years:
$1,106.40
That is before considering repairs or changes in electricity prices.
Why an Old Second Refrigerator Can Be Expensive
The problem with an old garage refrigerator is easy to overlook because there is no new purchase payment.
You already own the appliance, so keeping it feels free.
But electricity is a recurring cost.
ENERGY STAR advises consumers to consider replacing an old refrigerator and recycling an old second refrigerator. It notes that refrigerators more than 15 years old could cost about $95 per year to run.
If the appliance is used only for occasional drinks, overflow food, parties or holidays, the better financial question may be whether you need a second refrigerator running year-round at all.
Keep, Replace or Remove?
There are really three choices.
Option 1: Keep the Old Refrigerator
This avoids a new purchase today.
But you continue paying the old refrigerator's electricity cost every year.
Keeping it can make sense when the appliance is reasonably efficient, still reliable and genuinely useful.
Option 2: Replace It
A newer refrigerator may use less electricity, but energy savings alone do not automatically justify buying a new appliance.
You need to recover:
Purchase Price + Delivery + Installation − Rebates
through lower operating costs.
That is why the calculator shows a simple replacement payback period.
Option 3: Remove It
If you do not actually need a second refrigerator, removing it usually produces the largest direct electricity savings because future refrigerator electricity consumption falls to zero.
That does not mean removal is always practical.
A second refrigerator can provide valuable storage capacity for a large family, entertaining, bulk shopping or seasonal needs.
The calculator measures financial cost. You still need to decide how much that extra storage is worth to your household.
Old Garage Refrigerator vs. New Refrigerator
Suppose your current refrigerator uses 600 kWh per year while a potential replacement uses 400 kWh.
At 18.44 cents per kWh:
| Example | Annual Energy | Annual Electricity Cost | 10-Year Electricity Cost |
|---|---|---|---|
| Older Garage Refrigerator | 600 kWh | $110.64 | $1,106.40 |
| More Efficient Replacement | 400 kWh | $73.76 | $737.60 |
The annual electricity savings would be approximately:
$36.88
Over 10 years, before considering changes in electricity prices:
$368.80
If the replacement refrigerator costs $900 after delivery and rebates, electricity savings alone would not recover that purchase price within 10 years in this example.
This is why replacing a working refrigerator solely to save electricity does not always produce the lowest total cost.
What ENERGY STAR Data Tells Us
Annual energy consumption varies substantially among refrigerator designs, sizes and features.
ENERGY STAR's Product Finder publishes an Annual Energy Use figure in kWh/year for certified models.
For example, current certified side-by-side refrigerator listings include models around 420 kWh/year, while other certified side-by-side models are listed above 600 kWh/year.
That difference demonstrates why using an actual model's annual kWh figure is better than assuming that every new refrigerator has the same operating cost.
Where Can I Find My Refrigerator's Annual kWh?
Look for:
- the EnergyGuide label
- manufacturer specifications
- the appliance's model information
- ENERGY STAR Product Finder for certified products
If you know the model number, use the actual model data whenever possible.
Do not assume that age alone tells you exactly how much electricity your refrigerator consumes.
Does a Garage Refrigerator Use More Electricity in Summer?
A refrigerator moves heat from inside the cabinet to the surrounding environment.
The conditions around the appliance therefore matter.
A hot garage can make the refrigerator work harder to maintain its internal temperature than it would under milder conditions.
The actual effect depends on the refrigerator, ambient temperature, ventilation, door openings, food load and installation conditions.
For that reason, an annual kWh figure from a standardized test should be treated as a useful comparison value rather than a guarantee of your exact garage electricity consumption.
What About a Refrigerator in a Very Cold Garage?
Extreme cold can create a different problem.
A refrigerator designed for normal indoor conditions may not necessarily be intended to operate across the full temperature range found in an unconditioned garage.
If your garage becomes very hot in summer or very cold in winter, check the manufacturer's specified ambient operating range before purchasing or relocating a refrigerator.
This is especially important when evaluating products marketed for garage use.
What Does “Garage-Ready” Mean?
“Garage-ready” is generally used by manufacturers to describe appliances designed to operate across a wider range of ambient temperatures than a typical indoor refrigerator.
It should not be treated as a universal technical specification.
The supported temperature range varies by product.
Always check the manufacturer's actual operating-temperature specifications for the model you are considering.
Is a Second Refrigerator Worth It?
That depends on how much you use the additional storage.
A second refrigerator may make practical sense for households that regularly need extra refrigerated and frozen-food capacity.
But consider the utilization rate.
If a large second refrigerator runs 365 days a year primarily to hold a few drinks, the convenience may carry a surprisingly high cost per item stored.
A useful way to think about the decision is:
Annual Operating Cost ÷ Months of Meaningful Use
If the refrigerator is useful only during summer or holidays, year-round operation may not be necessary, assuming the appliance can be safely emptied, cleaned and stored according to manufacturer guidance.
Should You Unplug a Garage Refrigerator?
If you no longer need the refrigerator, unplugging and properly retiring or recycling it eliminates its future electricity consumption.
If you intend to use it only seasonally, follow the manufacturer's instructions for shutdown and storage.
Do not simply unplug a refrigerator containing food.
When storing an unused refrigerator, proper cleaning, drying and safe door management are also important.
Garage Refrigerator vs. Chest Freezer
If most of your extra storage is frozen food, a second full-size refrigerator may not be the only option.
A chest freezer can provide dedicated frozen-food storage with a very different capacity and energy-use profile.
The correct comparison is not simply which appliance uses less electricity.
Compare:
- the type of food you actually store
- required refrigerator versus freezer capacity
- annual kWh
- purchase price
- available garage space
- ambient operating-temperature requirements
If you primarily need frozen-food storage, compare the long-term cost of chest and upright freezers before automatically replacing an old garage refrigerator with another full-size refrigerator.
When Keeping the Old Garage Fridge Can Make Sense
Keeping the existing refrigerator can make financial sense when:
- its measured or rated energy use is reasonable
- it is reliable and in good condition
- you regularly use the extra storage
- a replacement would be expensive
- the electricity savings from a new refrigerator would take many years to recover the purchase cost
When Replacement Can Make Sense
Replacement becomes more attractive when:
- the old refrigerator consumes substantially more electricity
- the existing appliance is unreliable
- repairs are becoming frequent
- you need the second refrigerator year-round
- a suitable efficient replacement is available at a reasonable net price
- your local electricity rate is high
When Removal Is the Best Financial Choice
If you do not need the additional storage, removal is usually the lowest direct-cost option.
There is no new refrigerator purchase and no future electricity expense for the second unit.
This is also why ENERGY STAR specifically encourages consumers to consider recycling old second refrigerators rather than moving an inefficient primary refrigerator into the garage indefinitely.
Quick Decision Guide
| Situation | First Option to Evaluate | Why |
|---|---|---|
| Second fridge is rarely used | REMOVE | Eliminates recurring electricity use |
| Old fridge is efficient and heavily used | KEEP | Avoids unnecessary replacement cost |
| Old fridge uses much more energy and storage is necessary | REPLACE | Lower operating cost may offset purchase cost over time |
| Mostly storing frozen food | COMPARE FREEZERS | A dedicated freezer may better match the actual storage need |
| Garage has extreme temperatures | CHECK OPERATING RANGE | Not every refrigerator is designed for the same ambient conditions |
Frequently Asked Questions
How much does a garage refrigerator cost to run per month?
Divide its estimated annual electricity cost by 12. For example, a refrigerator using 600 kWh per year at 18.44 cents per kWh costs about $110.64 per year, or approximately $9.22 per month.
How much does a second refrigerator cost per year?
Multiply annual kWh consumption by your electricity rate. A 600 kWh refrigerator at 18.44 cents per kWh costs approximately $110.64 per year.
Does an old refrigerator use more electricity?
It can. ENERGY STAR specifically notes that refrigerators more than 15 years old could cost about $95 per year to operate and recommends considering replacement and recycling of an old second refrigerator.
Is it worth replacing an old garage refrigerator?
Not automatically. Divide the net replacement cost by the annual electricity savings. If the payback period is longer than you expect to own the replacement, energy savings alone may not justify the purchase.
Is it cheaper to unplug a second refrigerator?
If you do not need the extra storage, removing the refrigerator eliminates its future electricity consumption and is normally cheaper than operating or replacing it.
Does a refrigerator cost more to run in a hot garage?
Hot ambient conditions can increase the cooling work required. The exact effect depends on the appliance, garage temperature, installation and usage.
Can any refrigerator be used in a garage?
Do not assume so. Check the manufacturer's specified ambient operating-temperature range, particularly for an unconditioned garage that becomes very hot or cold.
Should I buy a garage-ready refrigerator?
If your garage experiences temperatures outside the operating range of a conventional refrigerator, a model specifically designed for the relevant conditions may be worth evaluating. Compare the actual manufacturer temperature specifications rather than relying on the marketing term alone.
Is a chest freezer cheaper than keeping a second refrigerator?
It depends on the actual models, annual kWh consumption, purchase price and whether you need refrigerated or frozen storage. If most of your extra storage is frozen food, compare dedicated freezer options before replacing a second refrigerator.
Methodology
CostCandid calculates current refrigerator annual electricity cost as:
Annual kWh × Electricity Rate × Months Used ÷ 12
The cost of keeping the refrigerator is:
Annual Electricity Cost × Ownership Period
Replacement cost is:
Purchase Price + Delivery / Installation − Rebate + New Refrigerator Electricity Cost
Simple replacement payback is:
Net Replacement Cost ÷ Annual Electricity Savings
The REMOVE scenario assumes no future electricity consumption from the second refrigerator.
The calculator does not assign a dollar value to lost storage capacity and does not include repair costs, financing, taxes, disposal costs, future electricity-price changes or the time value of money.
