What It Costs to Run a Refrigerator in 2026, by Size and Style

A median full-size French door refrigerator in our catalog draws 633 kilowatt-hours a year. At the current EIA national average residential rate of 16.65 cents per kWh (March 2026), that's about $105.39 a year to keep your food cold. A median top freezer at 362 kWh costs about $60.27. The layout you pick is a bigger lever on operating cost than the brand you pick.

We're going to walk through the numbers by layout, by size, and by feature flag, all calculated from spec sheets that ship with the federal ENERGY STAR certification on every model. No fabricated case studies. No "experts say." Just the kWh times the rate.

Annual cost by layout

The pattern: the simpler the layout, the lower the draw. Top freezer is the cheapest per cubic foot to run because the freezer sits where cold air naturally settles, and the doors lose less cold per opening than the wide doors on French and side-by-side models.

The pattern with one wrinkle: built-in models are surprisingly efficient. They draw a median of 530 kWh against the French door median of 633. They're shallower, so they have less interior volume to keep cold, and they're built to fit tight cabinet cavities with extra insulation requirements.

How size moves the number

Bigger fridge, more energy. The slope is gentler than people expect.

A 15 cu. ft. bottom freezer in our catalog typically draws around 380 to 420 kWh a year. A 25 cu. ft. bottom freezer of the same brand draws 480 to 540. That's roughly 50 percent more energy for 67 percent more food space, so kWh per cubic foot actually drops as the box gets bigger.

This is why "right-sizing" is more efficient than buying small. A household that overfills a 15 cu. ft. unit and crams the door full of condiments will run the compressor harder than a household that uses 70 percent of a 22 cu. ft. unit. The half-empty bigger box wins on annual cost.

The exception is the compact under-counter category. A 4 cu. ft. compact fridge draws around 258 kWh on the median, which is bad per cubic foot (68 kWh/cu. ft.) but small in absolute terms. Fisher & Paykel RS2435SB 5 cu. ft. Compact is a typical specimen at $1,300.

What features actually cost in kWh

Two questions come up constantly: does Wi-Fi raise energy use, and does the ice maker raise energy use.

Wi-Fi connectivity adds essentially nothing measurable. The module is on a low-voltage standby loop that draws around 1-2 watts. Over a year that's 9 to 18 kWh, or $1.50 to $3 at the EIA rate. Less than a single takeout meal.

Ice makers are different. A built-in automatic ice maker pulls 200 to 400 watt-hours per ice cycle and runs the cycle two to four times a day. That's 40 to 100 watt-hours per day, or 15 to 36 kWh a year, or $2.50 to $6 in extra energy. Plus the cost of the cold water you're freezing. Not large, but real.

Through-door water dispensers cost more than the ice maker if the dispenser includes a heater (a few premium models warm the water on demand). For the dispenser-only models, the cost is negligible.

The big feature that hurts efficiency is the dual-cooling system in some premium French doors. Two compressors, two evaporators, separate temperature control per compartment. They keep food fresher. They also draw 50 to 100 kWh more per year than single-cooling equivalents.

Where it goes wrong

Three habits inflate the bill.

The first is letting the seals fail. A leaky door gasket can double the compressor's workload. The fix is a $40 gasket strip and an hour with a hair dryer. People wait years.

The second is putting the fridge next to the dishwasher or oven and not vacuuming the back coils. Coil dust is the most overlooked maintenance item in the appliance category. A dusty coil makes the compressor work 10 to 20 percent harder. Pull the fridge out twice a year and vacuum.

The third is keeping it too cold. The right fresh-food temperature is 37°F (3°C); the right freezer temp is 0°F (-18°C). Most fridges ship with the dial in the middle, which is colder than necessary on roughly half the models in our catalog. Drop the fridge a degree and you'll save another 20 to 30 kWh a year.

What a really efficient model looks like

The most efficient full-size model in our catalog is Electrolux EI33AR80W 19 cu. ft. Bottom Freezer, a 19 cu. ft. bottom freezer that pulls 218 kWh a year. That's about $8 cents per cubic foot per year, against a class median of 27 cents.

At 16.65 cents per kWh, that 218 kWh model costs $36 a year. The least efficient bottom freezer at the same capacity pulls 880 kWh and costs $146 a year. Over ten years, the efficient model saves $1,100. The purchase-price premium for the efficient model is typically under $400, so it pays back in three to four years.

For a French door, Samsung RF27CG5010 26 cu. ft. French Door is the value pick: 26 cu. ft., 656 kWh/year, $2,550, ENERGY STAR Most Efficient candidate (depending on year). At the median rate, that's $109 a year to run.

Bottom line

If you're cost-sensitive on the bill, not the purchase price, get a top freezer; you'll pay around $60 a year. If you want the French door layout, the spread between models is large enough to matter; the efficient ones cost $100 a year and the inefficient ones cost $150. The ten-year operating cost is rarely the headline number people shop on, but it's the second-largest line item after purchase price in the full cost of owning a fridge. Worth two minutes of arithmetic.
