  We perform an analysis of the soft supersymmetry-breaking terms arising in
Calabi-Yau compactifications. The sigma-model contribution and the instanton
correction to the K\"ahler potential are included in the computation. The
existence of off-diagonal moduli and matter metrics gives rise to specific
features as the possibility of having scalars heavier than gauginos or the
presence of tachyons. Although non-universal soft terms is a natural situation,
we point out that there is an interesting limit where universality is achieved.
Finally, we compare these results with those of orbifold compactifications.
Although they are qualitatively similar some features indeed change. For
example, sum rules found in orbifold models which imply that on average the
scalars are lighter than gauginos can be violated in Calabi-Yau manifolds.
