Disclosed herein is an automatic baby formula mixing apparatus. A formula-dispensing unit is configured such that when a transfer tip is extracted from a formula container by a transferring means, powdered formula falls into a feeding bottle. A water-supplying unit includes a water reservoir and a hot water tank provided with a heating means. A sensor unit includes a temperature sensor and a flow sensor. A pump unit pumps water from either the water reservoir or the hot water tank into the other. A control unit controls the number of times of extraction of the transfer tip depending on a preset amount of powdered formula, controls the heating means, and controls the pump unit such that a preset amount of water is supplied from the hot water tank into the feeding bottle and then a predetermined amount of water is reversely pumped from the hot water tank into the water reservoir.
