It is known that a necessary condition for the existence of K\"ahler-Riccisolitons is the vanishing of the modified Futaki invariant introduced byTian-Zhu. In a recent work of Berman-Nystr\"om, it was generalized for(singular) Fano varieties and the notion of algebro-geometric stability of thepair $(M,V)$ of a Fano manifold $M$ and a holomorphic vector field $V$ wasintroduced. In this paper, we propose a method of computing the modified Futakiinvariant for Fano complete intersections in projective spaces.
