Because of its simplicity the CMSSM is one of the best studied and most popular supersymmetric models. The non-observation of convincing hints of new physics at the LHC, however, becomes challenging for this model once constraints from low energy observables are taken into account. While this is well known, it has so far been an open question what that means quantitatively for the validity of the model. We will present the first systematic investigation of this question, using global toy fits to calculate p-values for the CMSSM. We combine constraints from low-energy and astrophysical observables, Higgs boson mass and rate measurements as well as the non-observation of new physics in searches for supersymmetry at the LHC. Using the framework Fittino, we perform global fits of the CMSSM to the toy data.
