How much electricity does a refrigerator use? Cost breakdown by type

Reviewed.com pegs the typical fridge at $111 a year using $0.18/kWh as the rate. That number is a useful midpoint, but it hides the spread. A modern 18 cubic foot top-freezer ENERGY STAR model uses roughly 400 kWh per year, or $72 at the national average. A 25 cubic foot French door with through-the-door ice and water can pull 600 to 700 kWh, or $108 to $126. A 20-year-old side-by-side that has never had its coils cleaned can hit 1,200 kWh, or $217 annually. Same appliance category, three times the cost.

The fridge is the only major household appliance that runs every minute of every day for its entire service life. That makes it the appliance where small efficiency differences compound into real money. A 100 kWh per year gap between two models means $18 a year at the national average, or $54 in California, or $41 in Connecticut. Multiplied across a 15-year service life, that gap is $270 to $810 before any rate increases.

A refrigerator is a heat pump running in reverse. The compressor pulls heat out of the insulated cabinet and dumps it through condenser coils on the back or underneath. Modern compressors draw 100 to 250 watts when running, but they don't run continuously. They cycle on and off based on the thermostat, with a duty cycle of roughly 30 to 50% in normal household conditions. A 200-watt compressor running 40% of the time averages 80 watts of continuous draw, or about 700 kWh annually.

The compressor isn't the only load. The defrost heater, typically 400 to 600 watts, kicks on for about 20 minutes every 8 to 12 hours to clear frost from the freezer evaporator. That adds 30 to 60 kWh per year. The interior LED lights and control board add another 10 to 20 kWh. An automatic ice maker and water dispenser add 75 to 100 kWh, which is why French door models with these features run consistently higher than plain top-freezers of the same capacity.

Federal efficiency standards have tightened five times since 1990. A 1990 fridge used roughly 1,500 kWh per year. A 2001-standard model dropped to about 700 kWh. The 2014 standard cut another 25%. Current ENERGY STAR certified models run 400 to 500 kWh for standard sizes. The math: a 1990 fridge costs $271 a year at 18.05¢/kWh; the equivalent 2026 model costs $81. The difference is $190 a year, every year.

For replacement decisions, the rough rule is that any refrigerator older than 15 years is worth pricing out a new one against. A new ENERGY STAR top-freezer runs $700 to $1,200. At a $190 annual electricity savings, the payback period is 4 to 6 years before counting rebates. The DOE's ENERGY STAR program lists qualifying models and current rebates on the ENERGY STAR refrigerator finder. If the old fridge is in a garage or basement as a beer fridge, the payback math gets worse, because that fridge runs harder in temperature extremes and the food load is low.

A top-freezer is the cheapest format to run, period. Less surface area for heat to leak through, simpler door seals, fewer features drawing parasitic loads. A standard 18 cubic foot top-freezer uses about 400 kWh annually. The same capacity in a side-by-side runs roughly 500 to 550 kWh because of the larger door perimeter and the typical inclusion of an ice and water dispenser.

French door models, the dominant new-fridge category, land between 500 and 700 kWh per year. The bigger interior, the through-the-door dispenser, and the more complex sealing all add load. A counter-depth French door pulls slightly less because the cabinet is smaller. A built-in or column-style refrigerator runs the highest of any residential format, often 700 to 900 kWh, partly because of the size and partly because the heat-rejection path through cabinetry is less efficient than a freestanding unit.

A mini-fridge or compact runs 200 to 350 kWh per year despite being a fraction of the interior size. Compact compressors are less efficient per cubic foot, and many older mini fridges in dorms and offices predate ENERGY STAR rules entirely. A second mini-fridge in the garage as a beer fridge is one of the most common stealth costs in a home, contributing $40 to $80 a year that most people never attribute to it.

The same fridge using 500 kWh per year costs dramatically different amounts depending on where the house sits. State residential rates in 2026 range from 11.9¢/kWh in Louisiana to 41.2¢/kWh in Hawaii. At 500 kWh per year, that's $60 in Louisiana, $74 in Texas at 14.8¢, $90 at the national average, $144 in Connecticut at 28.7¢, and $206 in Hawaii.

Reviewed.com's $111 figure assumes 18¢/kWh, close to the national average. In reality, fewer than half of US households pay within a nickel of that rate. Hawaii pays double. Louisiana pays a third less. The whole point of running the math at your actual rate, not the national average, is that the answer can shift by $100 a year or more depending on where you live. Look up your state on the state rate pages to see what your number actually is.

Most efficiency levers for an existing refrigerator come back to two things: reducing how hard the compressor has to work, and keeping the heat-rejection path clear. Neither requires buying a new appliance.

• Vacuum the condenser coils every six months.Dust on the coils acts as insulation and forces the compressor to run longer to reject heat. The DOE estimates this single maintenance task restores 10 to 15% of efficiency on fridges over three years old. On a 600 kWh fridge at the national rate, that's $11 to $16 a year.
• Set the fridge to 37 to 40°F and the freezer to 0°F.Every degree colder than necessary adds 2 to 4% to the energy use. A fridge running at 33°F instead of 38°F can use 15 to 20% more electricity to maintain a temperature that doesn't preserve food any longer.
• Check the door gasket. A failing magnetic gasket lets warm air leak in continuously. The dollar bill test works: close the door on a bill, and if it pulls out without resistance, the gasket needs replacing. A new gasket costs $50 to $100 and can cut energy use 5 to 10% on a fridge with a worn seal.
• Move the fridge away from heat sources. A fridge next to an oven, in direct afternoon sun, or jammed against a wall with no ventilation has to fight a warmer environment. Even a few inches of clearance behind and above the unit measurably reduces compressor runtime.
• Unplug the second fridge.The garage beer fridge, the basement extra, the dorm-era mini in the home office: each one of these is adding $40 to $150 a year depending on age and size. If it's holding six beverages and a frozen pizza, the cost-per-item is absurd.

Wattage varies by model. Duty cycle varies by household and ambient temperature. State rates vary fivefold. The combination is why a generic annual estimate is only directional. Plug in your specifics below to see what your fridge actually costs at your rate.
