The cluster-multipole (CMP) expansion for magnetic structures provides a scheme to systematically generate candidate magnetic structures specifically including noncollinear magnetic configurations adapted to the crystal symmetry of a given material. A comparison with the experimental data collected on MAGNDATA shows that the most stable magnetic configurations in nature are linear combinations of only few CMPs. Furthermore, a high-throughput calculation for all candidate magnetic structures is performed in the framework of spin-density functional theory (SDFT). We benchmark the predictive power of $\mathrm{CMP}+\mathrm{SDFT}$with 2935 calculations, which show that (i) the CMP expansion administers an exhaustive list of candidate magnetic structures, (ii) $\mathrm{CMP}+\mathrm{SDFT}$can narrow down the possible magnetic configurations to a handful of computed configurations, and (iii) SDFT reproduces the experimental magnetic configurations with an accuracy of$\pm 0.5{\mu }_B$. For a subset the impact of on-site Coulomb repulsion $U$is investigated by means of 1545 $\mathrm{CMP}+\mathrm{SDFT}+U$calculations revealing no further improvement on the predictive power.
