Garage refrigerator: electricity cost calculator
Quick answer: a typical garage refrigerator costs about $11/month while in use at the U.S. average electricity price (18.44¢/kWh) — about $135 per year. Your number depends on wattage, runtime and your state — calculate it below.
Second refrigerators are typically 10–20 years old and sit in unconditioned garages, where summer heat forces long compressor runtimes. Many cost more to run per year than a new unit costs to buy over its life.

Methodology & sources
Cost = watts ÷ 1,000 × hours × price per kWh. Electricity prices are average residential prices by state from the EIA Electric Power Monthly, Table 5.6.A (May 2026). EIA averages include delivery charges and taxes but are not any specific utility tariff — for an exact figure, use the rate from your own bill. Wattage presets reflect common product ranges; check your appliance's nameplate or a plug-in power meter for its true draw.
