We present the currently most precise W boson mass (M-W) prediction in the Minimal Supersymmetric Standard Model (MSSM) and discuss how it is affected by recent results from the LHC. The evaluation includes the full one-loop result and all known higher order corrections of SM and SUSY type. We show the MSSM prediction in the M-W-m(t) plane, taking into account constraints from Higgs and SUSY searches. We point out that even if stops and sbottoms are heavy, relatively large SUSY contributions to M-W are possible if either charginos, neutralinos or sleptons are light. In particular we analyze the effect on the M-W prediction of the Higgs signal at about 125.6 GeV, which within the MSSM can in principle be interpreted as the light or the heavy CP-even Higgs boson. For both interpretations the predicted MSSM region for M-W is in good agreement with the experimental measurement. We furthermore discuss the impact of possible future LHC results in the stop sector on the M-W prediction, considering both the cases of improved limits and of the detection of a scalar top quark.
