  We calculate the orbifold Euler characteristics of all the degree d fine
universal compactified Jacobians (defined by Pagani and Tommasi) over the
moduli space of stable curves of genus g with n marked points. We show that
this orbifold Euler characteristic agrees with the Euler characteristic of the
moduli space of stable, genus 0 curves with 2g+n markings up to a combinatorial
factor, and in particular, is independent of the degree d and the choice of
degree d universal fine compactified Jacobian. As a special case, we see that
the universal fine compactified Jacobians defined by Kass and Pagani, depending
on a universal polarization, have orbifold Euler characteristic independent of
this choice of polarization.
