We present a complete analysis of the individual components of the ABC visual triple system HIP 32475. AB pair was discovered during the Hipparcos mission, with a separation of 412 mas. Later, in 2015, a third component was added to the system by discovering it at a small angular distance from B. In our analysis, we follow Al-Wardat's method for analyzing binary and multiple stellar systems, which is a computational spectrophotometric method. Using estimated parameters, the components' positions on the H-R diagram, evolutionary tracks, and isochrones are defined. Depending on the analysis, we estimate the age of the system as 1.259 Gyr with a metallicity of Z=0.019. The results show that component A started to evolve from the main sequence to the sub-giants stage, while components B and C are still in the main sequence stage.
