  Rates of stellar tidal disruption events (TDEs) around supermassive black
holes (SMBHs) have been extensively calculated using the loss cone theory,
while theoretical work on TDE rates around intermediate-mass black holes
(IMBHs) has been lacking. In this work, we aim to accurately calculate the IMBH
TDE rates based on their black hole masses and the stellar profiles of their
host galaxies obtained from the latest observations. We find that IMBH TDEs
from the center of small galaxies have an overall rate comparable to SMBH TDEs,
while off-nuclei IMBH TDEs from globular clusters have a much lower rate. Very
interestingly, we show that the rate of IMBH TDE per galaxy generally increases
with the black hole mass, which is opposite to the trend seen in SMBH TDEs.
Furthermore, we report that IMBH TDEs typically occur in the pinhole regime,
which means that deeply plunging events are more likely for IMBH TDEs compared
to SMBH TDEs. We also calculate the volumetric TDE rates for IMBH and SMBH TDEs
and compare with observed rates.
