We have made a very accurate calculation of the relic density of neutralino dark matter in the minimal supergravity framework. This calculation includes all so-called coannihilations and it uses the DarkSUSY package. In agreement with earlier analyses, we find that coannihilations have a huge effect on the density and this extends the interval of neutralino masses which are cosmologically favoured. We quantify the effect of coannihilations and the neutralino mass bounds.
