How much does it cost to run a mini fridge?

Data checked October 2026

Short answer

The average new mini fridge uses 257 kWh a year — about $46.75 a year or $3.90 a month at the U.S. average of 18.19¢/kWh.

That's the average of 1,769 ENERGY STAR certified compact / mini fridge models: 0.7 kWh and $0.13 a day, an average draw of about 29 W as the compressor cycles.
Its EnergyGuide label would say $35.98 a year — it prices electricity at 14¢/kWh, not today's 18.19¢.
It uses 109 kWh a year less than an average full-size top-freezer refrigerator.
In North Dakota it costs $32.02 a year; in Hawaii $119.
An older unit can use much more than these new-model averages — a plug-in meter left on for 2–3 days tells you exactly.

How to cut it

Measure an old fridge with a plug-in meter (a Kill A Watt handles up to 15 A) before deciding to replace it.
Keep door gaskets clean and sealing, and vacuum the condenser coils if they're exposed.
A garage fridge works harder in summer heat; one you don't need is pure cost.

Mini fridge: yearly running cost in the cheapest and priciest states

Hawaii	46.41	$9.94	$119

How this was worked out

257 kWh × 18.19¢ = $46.75 a year; ÷ 12 = $3.90 a month. The kWh figure comes from the federal test behind the EnergyGuide label, so it already includes the compressor cycling on and off.
