Quick Answer

A refrigerator draws roughly 100 to 400 watts while the compressor is actually running — but it doesn’t run all the time, so the number that matters is not watts. It’s kilowatt-hours per day: typically 1 to 2 kWh/day for a modern full-size fridge, 2 to 3 or more for older or oversized units. Because the compressor cycles, a fridge’s “watts” change minute to minute and no single reading predicts a bill. The meaningful measurement is cumulative energy — from a $15-30 plug-in meter, or a free one from many public libraries.
