  Mass outflow rates and loading factors are typically used to infer the
quenching potential of galactic-scale outflows. However, these generally rely
on observations of a single gas phase which can severely underestimate the
total ejected gas mass. To address this, we use observations of high mass
($\geqslant$10$^{10}$ M$_{\odot}$), normal star-forming galaxies at $z\sim$0
from the MaNGA, xCOLD GASS, xGASS and ALFALFA surveys and a stacking of NaD,
H$\alpha$, CO(1-0) and HI 21cm tracers with the aim of placing constraints on
an average, total mass outflow rate and loading factor. We find detections of
outflows in both neutral and ionised gas tracers, with no detections in stacks
of molecular or atomic gas emission. Modelling of the outflow components
reveals velocities of $|$v$_{\text{NaD}}|$=131 km s$^{-1}$ and
$|$v$_{\text{H}\alpha}|$=439 km s$^{-1}$ and outflow rates of
$\dot{M}_{\text{NaD}}$=7.55 M$_{\odot}$yr$^{-1}$ and
$\dot{M}_{\text{H}\alpha}$=0.10 M$_{\odot}$yr$^{-1}$ for neutral and ionised
gas, respectively. Assuming a molecular/atomic outflow velocity of 200 km
s$^{-1}$, we derive upper limits of $\dot{M}_{\text{CO}}<$19.43
M$_{\odot}$yr$^{-1}$ and $\dot{M}_{\text{HI}}<$26.72 M$_{\odot}$yr$^{-1}$ for
the molecular and atomic gas, respectively. Combining the detections and upper
limits, we find average total outflow rates of $\dot{M}_{\text{tot}}\lesssim$27
M$_{\odot}$yr$^{-1}$ and a loading factor of $\eta_{\text{tot}}\lesssim$6.39,
with molecular gas likely contributing $\lesssim$72% of the total mass outflow
rate, and neutral and ionised gas contributing $\sim$28% and $<$1%,
respectively. Our results suggest that, to first order, a degree of quenching
via ejective feedback could occur in normal galaxies when considering all gas
phases, even in the absence of an AGN.
