Apartment-size refrigerators—compact units designed for small kitchens, studios, and renters—use less electricity than full-size models simply because they hold less and cool a smaller volume. But efficiency still varies widely. An old or inefficient apartment fridge can cost more to run per cubic foot than a new ENERGY STAR model, and in a building where you pay your own electric bill, those differences add up. This guide covers how much energy apartment refrigerators typically use, how to read the EnergyGuide label, ways to cut costs without replacing the unit, and when upgrading to a more efficient model pays off.
Why Apartment Refrigerator Energy Use Matters
In many apartments, the tenant pays electricity. Refrigerators run 24/7, so they are one of the few appliances that contribute to your bill every day. According to the U.S. Energy Information Administration, refrigeration accounts for a meaningful share of residential electricity use. A compact or apartment-size refrigerator uses less energy in absolute terms than a full-size unit, but older or poorly maintained small fridges can still use 400 kWh or more per year. At 15 cents per kWh, that is $60 or more per year. A newer ENERGY STAR apartment-size model might use 200 to 280 kWh per year, cutting that cost roughly in half. Over a few years, the savings can offset part of the cost of a new unit, and you get better cooling and reliability.
Landlords who include utilities sometimes provide the oldest, cheapest refrigerator in the building. If you have no control over the appliance, you can still use the tips in this guide to reduce how hard it works. If you are allowed to replace it or are shopping for your first apartment fridge, choosing an efficient model and the right size will keep your energy use and bills lower.
Typical Energy Use for Apartment-Size Refrigerators
Apartment refrigerators are generally under 18 cubic feet and often in the 10- to 14-cubic-foot range. The U.S. Department of Energy and the Environmental Protection Agency set efficiency standards and certify models that meet strict criteria. ENERGY STAR-qualified compact refrigerators (under 7.75 cu ft) and small refrigerators (7.75 to 18 cu ft) must use no more than a certain amount of energy per year, based on size and configuration. Those limits are updated periodically; current criteria are published on the ENERGY STAR website.
As a rough guide, a modern apartment-size refrigerator with a top or bottom freezer might use 200 to 350 kWh per year depending on size, age, and efficiency. Mini fridges and very small units (under 8 cu ft) often use 200 to 280 kWh per year when they are ENERGY STAR certified. Older units from the 1990s or early 2000s can use 400 to 600 kWh or more. The only way to know for your specific model is to check the EnergyGuide label (if you still have it), look up the model in the DOE database, or use a plug-in energy monitor for a few days and extrapolate.
Reading the EnergyGuide Label
New refrigerators sold in the United States carry a yellow EnergyGuide label. It shows estimated yearly electricity consumption in kilowatt-hours and compares the model to others in the same category (e.g. compact refrigerators, top-freezer). The label also shows the estimated yearly operating cost at a sample electricity rate—often around 12 cents per kWh. Your actual cost depends on your local rate; in high-cost areas you might pay 25 to 40 cents per kWh, so the real cost can be two or three times the label number.
Use the EnergyGuide label to compare models before you buy. A lower kWh number means lower energy use and lower bills. ENERGY STAR certification means the model meets the EPA’s efficiency requirements for its size class. When you compare apartment refrigerators at Fridge.com, you can filter by ENERGY STAR and see capacity and dimensions alongside so you choose a unit that fits your space and your budget.
What Affects Apartment Refrigerator Energy Use
Size is the biggest factor: a larger refrigerator has more interior volume to cool and more surface area through which heat enters, so it uses more energy. Configuration matters too. Top-freezer models tend to be more efficient than side-by-side or French door units of the same size because the freezer is in a single block and there are fewer seals and less cold air loss when you open the door. Defrost type also affects efficiency: manual defrost uses the least energy but requires you to defrost periodically; automatic defrost is more convenient but uses more energy.
Condition and placement matter. A dirty condenser coil, a worn door gasket, or a unit placed in a hot spot (next to the stove, in direct sunlight, or in a poorly ventilated alcove) will use more electricity. Keeping the coil clean, the seal tight, and the fridge away from heat sources and with adequate clearance at the back helps it run efficiently. Setting the thermostat too cold also increases use; the refrigerator compartment should be 37–40°F and the freezer 0°F for food safety and efficiency.
How to Reduce Energy Use Without Replacing the Fridge
If you are stuck with an existing apartment refrigerator, you can still trim its energy use. Keep the condenser coil clean. On most models the coil is on the back or underneath; pull the fridge out carefully (or ask maintenance to do it) and vacuum or brush the coil every few months. A dirty coil makes the compressor work harder and use more electricity.
Check the door gasket. If the seal is cracked, loose, or cold to the touch when the door is closed, cold air is escaping. Close the door on a dollar bill in several spots; if the bill slides out easily, the seal may need replacing. Some landlords will replace the gasket; if not, you can order one by model number. A good seal reduces run time and energy use.
Do not overfill the fridge. Packed shelves block airflow and make the compressor run longer. Leave some space so cold air can circulate. Similarly, do not put hot food directly in the refrigerator; let it cool to room temperature first so the fridge does not have to work to remove that heat. Keep the door closed as much as possible and avoid opening it unnecessarily.
Set the temperature correctly. Use a thermometer in the refrigerator and freezer compartments and adjust the dial or digital control so the fridge stays at 37–40°F and the freezer at 0°F. Colder than that wastes energy; warmer risks food safety. If the unit is in a very hot room, it will run more; improving ventilation or moving it away from the stove or sun can help.
When to Replace an Old Apartment Refrigerator
If the refrigerator is 15 years old or more, is noisy, does not hold temperature well, or has repeated repairs, replacing it with an ENERGY STAR model usually pays off within a few years through lower electric bills and fewer service calls. Use the Energy Cost Calculator at Fridge.com to estimate annual cost for your local electricity rate and compare it to the estimated use of a new model. If you are a renter, check your lease and building policy; some landlords will replace an aging refrigerator if you ask, or allow you to install your own and take it when you leave.
When you replace, choose the smallest size that meets your needs. A 10-cubic-foot refrigerator uses less energy than a 14-cubic-foot unit. If you live alone or with one other person and do not stockpile food, a compact or small apartment-size model is usually enough and will cost less to run than a full-size fridge.
ENERGY STAR for Compact and Small Refrigerators
ENERGY STAR sets separate criteria for compact refrigerators (under 7.75 cu ft) and for small refrigerators (7.75 to 18 cu ft). The limits are maximum annual energy consumption in kWh; models that meet or beat the limit qualify for the label. The criteria are updated every few years to reflect improved technology, so a unit that qualified in 2020 may not qualify under 2024 criteria. When you shop, look for the current ENERGY STAR logo and, if possible, the exact kWh on the EnergyGuide label so you can compare.
ENERGY STAR does not guarantee the lowest possible energy use—there may be non-certified models that use less—but it is a reliable way to filter for efficient options. In many states and localities, utility rebates or incentives are available for purchasing ENERGY STAR refrigerators; check your utility’s website or the ENERGY STAR rebate finder.
Estimating Your Apartment Refrigerator’s Cost to Run
To estimate annual cost, you need the refrigerator’s yearly energy use in kWh and your electricity rate in dollars per kWh. Your rate is on your electric bill, often listed as “price per kWh” or in the rate schedule. Multiply yearly kWh by the rate: for example, 300 kWh × $0.15/kWh = $45 per year. If you do not know the kWh, you can use a plug-in energy monitor for a week and multiply the weekly average by 52 to get a rough yearly figure. New models have the number on the EnergyGuide label.
Rates vary widely. The EIA reports average residential rates by state; some states average under 10 cents per kWh, others over 25 cents. If you are in a high-rate area, even a small refrigerator can cost $80 or more per year to run if it is old or inefficient. That makes the payback for a new ENERGY STAR unit shorter.
Renter Considerations
If you do not own the refrigerator, you may not be able to replace it. Focus on maintenance: clean the coil, check the gasket, set temperatures correctly, and avoid overfilling or blocking airflow. If the fridge is clearly inefficient or broken, document the issue and ask the landlord or management to repair or replace it. In some jurisdictions, a working refrigerator is required for habitability; an old unit that barely cools or runs constantly may not meet that standard.
If you are allowed to provide your own refrigerator, choose an ENERGY STAR apartment-size model that fits your space. When you move, you can take it with you or sell it. Keep the manual and EnergyGuide information so you can prove efficiency and capacity to the next tenant or buyer.
Summary
Apartment refrigerators use less energy than full-size units but efficiency still varies. New ENERGY STAR compact and small refrigerators typically use 200 to 350 kWh per year; older units can use 400 kWh or more. Read the EnergyGuide label to compare energy use and estimated cost. You can cut use by cleaning the coil, checking the door seal, setting the right temperature, and keeping the fridge away from heat. When it makes sense to replace, choose the smallest size that meets your needs and look for ENERGY STAR. Use the Energy Cost Calculator at Fridge.com to estimate annual cost for your rate and compare apartment refrigerators by efficiency and size.
