Off-stoichiometric Ni$_2$MnIn Heusler alloys have drawn recent attention dueto their large magnetocaloric entropy change associated with the first-ordermagneto-structural transition. Here we present crystal structural, calorimetricand magnetic studies of three compositions. Temperature-dependent X-raydiffraction shows clear structural transition from a 6M modulated monoclinic toa L2$_1$ cubic. A significant enhancement of relative cooling power (RCP) wasachieved by tuning the magnetic and structural stability through minorcompositional changes, with the measured results quantitatively close to theprediction as a function of the ratio between the martensitic transition($T_m$) temperature and austenite Curie temperature ($T_C$) although themaximal magnetic induced entropy change ($\Delta S_{max}$) reduction isobserved in the same time. The results provided an evaluation guideline of RCPsas well as magnetic-induced entropy change in designing practical activematerials.
