We have reached a new era of particle physics in which the properties of the Higgs boson, in particular its mass, turned into precision observables. Therefore, it is necessary to have accurate predictions of these properties in models for new physics. I give an overview of available tools for supersymmetric and non-supersymmetric models which are publically available. Afterwards, the main idea behind generic tools to study a large variety of models is summarised. Also some remarks about the validity of checks for perturbative unitarity, which are often applied for non-supersymmetric models, are given.
