The complete fermionic two-loop contributions to the prediction for the W-boson mass from muon decay in the electroweak Standard Model are evaluated exactly, i.e. no expansion in the top-quark and the Higgs-boson mass is made.The result for the W-boson mass is compared with the previous result of an expansion up to next-toleading order in the top-quark mass.The predictions are found to agree with each other within about 5 MeV.A simple parametrization of the new result is presented, approximating the full result to better than 0.4 MeV for M H ≤ 1 TeV.
