Building on previous answers, I've come to this solution to make it work for PostgreSQL:

from django.db.models import Func

class Round2(Func):
    function = "ROUND"
    template = "%(function)s(%(expressions)s::numeric, 2)"

# Then use it as ,e.g.:
# queryset.annotate(ag_roi=Round2("roi"))

# qs.aggregate(ag_sold_pct=Round2(Sum("sold_uts") / (1.0 * Sum("total_uts"))) * 100
