Higher-order results for electroweak precision observable in the Standard Model and the MSSM are discussed in view of the present and prospective future experimental accuracy at LEP2 and the Tevatron, the LHC, and a future linear collider. In the Higgs sector of the MSSM, recent diagrammatic two-loop results are compared with previous results based on renormalization group methods. The impact of the new results on the analysis of the LEP2 data is investigated. The upper bound on the mass of the lightest CP-even Higgs boson is analysed within the unconstrained MSSM as well as in the M-SUGRA and the GMSB scenario.
