To be more accurate with this, you might want to consider what portion
of every part of the overall network is attributed to the costs your
customer burdens you with. This isn't necessarily easy to do, but is
more accurate than thinking of only the box the customer physically
connects to.

You will spend differently in different parts of the network, e.g.,
peering, core, edge, services, e.t.c.

How much of that goes back to (or is caused by) your customers?
