In this paper we show the existence of $\varphi$ satisfying the estimate $$ \|\varphi-\operatorname{id}\|_{C^{r+1,\alpha}} \leq C\|g\|_{C^{r+1,\alpha}}\|f-g\|_{C^{r,\alpha}} $$ together with the Jacobian equation $$ g\circ \varphi \det\nabla \varphi=f. $$ We, moreover, prove that the previous estimate is sharp.
