A numerical controller includes: a model holding unit that holds a machine model, the machine model being a model that simulates deformation of a mechanical structure accompanying motion of the mechanical structure in axial directions and representing an error amount as an amount of displacement of a tool; a machining error estimation unit that estimates an error direction and the error amount in the error direction on the basis of axis data that is data on drive of a drive mechanism and the machine model, the error direction being a direction in which displacement of the tool occurs among the axial directions; and a correction amount arithmetic unit that selects one or more of the axes subject to correction, and performs arithmetic to find a correction amount used for correction of a command to be output to the drive mechanism for the axis selected.
