We present the possibility of calculating the quark flavor changing neutral current decays $B_{s}^0\to \ell \bar \ell$ and $B_{d}^0\to \ell \bar \ell$ for a large variety of supersymmetric models. For this purpose, the complete one-loop calculation has been implemented in a generic form in the {\tt Mathematica} package {\tt SARAH}. This information is used by {\tt SARAH} to generate {\tt Fortran} source code for {\tt SPheno} for a numerical evaluation of these processes in a given model. We comment also on the possibility to use this setup for non-supersymmetric models.
