To a first approximation 10% of all incoming net traffic is malware/abuse/junk related, so if you are a residential ISP presumably 10% of outgoing bandwidth is swallowed up this way. So there are savings to be made, of course the economies work against it, as it is generally cheaper to by bandwidth in bulk, than deal with individual cases. However most big residential ISPs must be getting to the point where 10% bandwidth saving would justify buying in third party solutions for containing malware sources. I assume residential ISPs must be worse than 10%, as I hope businesses do slightly better on average. On the upside, over here, the migration to ADSL, means that "containing" an infected host via a third party can be as simple as changing the ADSL settings so they connect to a third party walled garden rather than the host ISP (effectively transferring them to a different ISP, just one who exists solely for cleaning up infected systems).
