Abstract The mass of 40Ti has been determined by using the isobaric multiplet mass equation method. The experimental data of 40Ti β-decay were used to determine the level of the isospin analog state of 40Sc. The ground-state mass excess and the QEC value for 40Ti were determined to be -9060±12keV and 11466±13keV, respectively.
