The new prescription is based on results of detailed spectral analyses of WC and WO stars, and improves the often applied Nugis & Lamers (2000) relation. We find that the mass-loss rates of WC and WO stars (with $X=0$ and $Y < 0.98$) can be expressed as $\\log{\\dot{M}} = -9.20 + 0.85\\log{(L/L_{\\odot})} + 0.44\\log{Y} + 0.25\\log{(Z_{\\mathrm{Fe}}/Z_{\\mathrm{Fe}, \\odot})}$.
