The impact of the uncertainty of nuclear mass predictions on -decay half-lives is investigated based on the gross theory. It is found that the gross theory can better describe the nuclear -decay half-lives of nuclei with larger -decay energies, which even reproduces the experimental half-lives within about 1.6 times for the nuclei with -decay energies greater than 15 MeV. Based on the nuclear mass predictions from various models, an approximately monotonic relationship is found between the accuracies of the nuclear mass and -decay half-life predictions when the accuracies of the mass models are better than 1 MeV. It is also found that the uncertainties of -decay half-lives from nuclear mass predictions are relatively large for the heavy nuclei and the nuclei near the neutron-drip line.
