We study SUSY models in the context of LHC searches and LHC exclusion bounds and explore models in the parameter range that are accessible at the future runs of the LHC and at a future Linear Collider. We study the impact of precision measurements of masses, cross sections and further observables, for instance as forward-backward asymmetries, to determine the fundamental SUSY parameters for dark matter predictions. We perform our dark matter predictions from the model-independent parameter determination at full one-loop order corrections and study which experimental observables are most powerful with regard to the dark matter constraints. Different SUSY models, MSSM, NMSSM etc. have been investigated and we also include challenging scenarios, as for instance light higgsino-like scenarios, in our study. The expected prospects at a high luminosity LHC as well as at a future ILC are discussed.
