We describe a criterion for a natural Euler characteristic that takes values in a relative algebraic $K_0$-group to be additive in distinguished triangles. As preliminary steps we prove several results about determinant functors, in particular concerning the comparison of the determinant of a complex to the determinant of its cohomology.
