there is no cost for replacing any routers.
That depends on your router. In the case of a company I happen to have
some familiarity with, some of the products we have that switch traffic
in hardware require a change of card (not the entire router, unless it
is old enough that it is no longer supported). The new card is
IPv4+IPv6 and has a 64 or 128 bit wide word width and may have a larger
TCAM where the old was IPv4 only and had a 32 bit word width. Even a
software router may require additional memory to hold a larger program
and parallel RIBs and FIBs.
A new memory stick is a cost, and sending someone out to inventory the
equipment and see if one might be needed (and testing the software
before basing one's business on it) is a cost.
