Let $X$ be a smooth projective toric variety and let $\widetilde{X}$ be the blow-up manifold of $X$ at finitely many distinct tours invariants points of $X$. In this paper, we give an explicit combinatorial formula of the Chow weight of $\widetilde{X}$ in terms of the base toric manifold $X$ and the symplectic cuts of the Delzant polytope. We then apply this blow-up formula to the projective plane and see the difference of Chow stability between the toric blow-up manifolds and the manifolds of blow-ups at general points. Finally, we detect the blow-up formula of the Futaki-Ono invariant which is an obstruction for asymptotic Chow semistability of a polarized toric manifold.
