  We compute the quantum gravitational contributions to the standard model
effective potential and analyze their effects on the Higgs vacuum stability in
the framework of effective field theory. Non-renormalizability of Einstein
gravity induces higher dimension $\phi^{6}$ and $\phi^{8}$ operators at the
one-loop level with novel couplings $\eta_{1/2}$. The beta functions of these
couplings are established and the impact of the gravity induced contributions
on electroweak vacuum stability is studied. We find that the true minimum of
the standard model effective potential now lies below the Planck scale for
almost the entire parameter space ($\eta_{1/2}(m_\text{t})> 0.01$). In addition
quantum gravity is shown to contribute to the minimal value of the standard
model NLO effective potential at the percent level. The quantum gravity induced
contributions yield a metastable vacuum for a large fraction of the parameter
space in the flowing couplings $\eta_{1/2}$.
