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 Q_EC value for ⁴⁰Ti were determined to be -9060±12keV and 11466±13keV, respectively.
