How much does it cost to run most efficient refrigerators?

Among 861 certified models in this data, most efficient refrigerators cost $19 to $101 a year to run at the U.S. average electricity rate (18.3¢/kWh) — a median of $66.

Do most efficient refrigerators cost more or less than the average refrigerator?

The median model here runs $66 a year, 5% more than the $63 median across all certified refrigerators.

What's the cheapest model among most efficient refrigerators?

The DOMETIC C40S1 costs about $19 a year at the U.S. average rate (106 kWh/yr) — the lowest certified figure in this group.

What does the certified annual-kWh figure assume for refrigerators?

The certified annual kWh comes from the DOE test procedure, which measures continuous 24/7 operation at standardized temperatures — refrigerators never get a day off.
