We provide an estimate for the essential norm of a weighted compositionoperator $W_{\psi,\varphi}\colon f\mapsto \psi(f\circ\varphi)$ acting on thespace $BMOA$ in terms of the weight function $\psi$ and the $n$-th power$\varphi^n$ of the analytic self-map $\varphi$ of the open unit disc$\mathbb{D}$. We also provide a new estimate for the norm of the weightedcomposition operator on $BMOA$.
