A fridge is not a big spike. It is a quiet all-day load. The compressor cycles, the door gets opened, and the coil behind it slowly loads with dust. That is why a refrigerator can rival a “sometimes” appliance on the monthly total even though it never sounds dramatic.
Modern household refrigerators often draw a few hundred watts when the compressor is actually running, but they are not running every minute. Over a day the useful number is average watts × 24 hours. An older or poorly sealed unit spends more of the day at that higher draw.
Door time, a packed freezer section that cannot circulate, and a dirty condenser coil all stretch runtime. A mini-fridge in a dorm is a different card in Whatt — smaller box, often a less efficient compressor, still 24/7.
Whatt treats a refrigerator as an always-on appliance with a typical household wattage you can change. The estimate is energy for the box, not the grocery bill and not ice-maker water (that is a separate water card).
At 18.8¢ per kWh, a fridge that averages about 50 watts over the whole day uses about 1.2 kWh — roughly 0.23 a day, or about 6.80 in a 30-day month. If your unit is older and averages closer to 100 watts, that monthly usage line roughly doubles.
The sticker
Energy Guide on the door jamb is yearly kWh. Divide by 365 for a daily kWh guess, then Fine-tune in Whatt. Mini-fridges and beverage fridges are other cards — smaller box, often worse watts per cubic foot.
What people mix up
Ice-maker water is not this card. The freezer drawer inside a kitchen fridge is already in this estimate. A garage chest freezer is Freezer.
