Refrigerator: the short answer
Running a typical 150 W refrigerator about
24 hours a day costs roughly
$0.61 a day, $18.61 a month, and
$223.38 a year at the $0.17/kWh US average — about 3.6 kWh a day.
A refrigerator runs around the clock but cycles its compressor, so it's modeled as an effective average of about 150 W over 24 hours rather than its peak draw.

These are indicative figures, not a bill. Your real cost depends on the
unit's actual wattage, how long you run it, and your local rate. Enter your own watts and
the $/kWh from your bill in the calculator above for an accurate estimate.
Cycling appliances don't run at full power continuously.
Indicative: typical 150 W × 24 h/day at the $0.17/kWh US
average, as of 2026-06. Use your bill for accuracy.
