Assuming the Minimal Standard Model (MSM) Higgs sector the present electroweak data concerning their sensitivity to the Higgs-boson mass are analyzed. Already the LEP data alone show a sensitivity to the Higgs-boson mass. Together with all other electroweak data from the SLC, the {bar p}-colliders, the {nu}N-experiments and in particular the CDF top-quark mass determination it is possible to give an upper 95% CL limit (corresponding to an increase of 2.7 in {chi}{sup 2}) of 490 GeV for the Higgs-boson mass. Extrapolating the current experiments to 1995 one finds that the LEP data alone even in the most optimistic case will not give a useful upper limit on m{sub H}. The measurement of the W-boson mass at LEP200 will also not significantly improve the sensitivity to m{sub H}. However in combination with all other electroweak data in 1995 an interesting upper limit on M{sub H} could be reached. If the Higgs-boson is not discovered at LEP200 the significance of the data will not be strong enough to exclude the MSM.
