We present the results of our investigation on the geometrical and physical parameters of the W UMa-type binary V546 And from analyzed CCD (BVRI) light curves and radial velocity data. The photometric data were obtained in 2010 and 2011 at Ankara University Observatory (AUO) and the spectroscopic observations were made in 2010 at TUBITAK National Observatory (TUG). Light and radial velocity observations were analyzed simultaneously by using the Wilson-Devinney (2013 revision) code to obtain absolute and geometrical parameters. The system was determined to be a W-type W UMa system. Combining our photometric solution with the spectroscopic data we derived masses and radii of the eclipsing system to be M-1 = 0.275 M-circle dot, M-2 = 1.083 M-circle dot, R-1 = 0.661 R-circle dot and R-2 = 1.229 R-circle dot. We finally discuss the evolutionary status of the system.
