An additive manufacturing apparatus manufactures a shaped object by stacking a bead that is a solidified product of a filler metal caused to be melted. The additive manufacturing apparatus includes: a feeding unit that feeds the filler metal to a workpiece; a beam source that outputs a beam for melting the filler metal that is fed; and a position calculation unit that calculates a tip position of the filler metal, the tip position being a position where a temperature reaches a melting point of the filler metal by irradiation with the beam, on the basis of a feeding speed of the filler metal to be fed to the workpiece and beam power from the beam source.
