We calculate the electroweak and finite width corrections to the decay of an unpolarized top quark into a bottom quark and a W-gauge boson where the helicities of the W are specified as longitudinal, transverse plus and transverse minus. Together with the $O({\ensuremath{\alpha}}_{s})$ corrections these corrections may become relevant for the determination of the mass of the top quark through angular decay measurements.
