Disclosed are a refrigerator and a home appliance. The refrigerator includes a compressor, an input current detector (A) configured to detect input current of alternating current (AC) power input to the refrigerator, a converter configured to convert the input AC power into direct current (DC) power, a capacitor (c) configured to store the converted DC power, an inverter (420) configured to output AC power using the converted DC power for driving of the compressor, a DC terminal voltage detector (B) configured to detect voltage at two terminals of the capacitor (c), and a compressor microcomputer configured to control the inverter and to calculate refrigerator power consumption based on the detected input current and the detected DC terminal voltage. The refrigerator enables simplified power consumption calculation.
