Though I would agree with Derek that that is the clean thing to do ATM,
there is support for formulas in the expressions right now; they are
defined in scheme in src/scm/fin.scm.

One outstanding bug is to better represent the formula containing the
variable being bound at since-last-run time to make that adjustment
process easier [knowing that the 'adj' var you are binding is going to
'adj'ust the default value of $125, or whatever].

WRT having an external table or external data-source lookup for a datum of
the function/formula ... this is something that very-advanced-budgeting
might want as well [lookup regional/national fuel costs, for instance,
to predict current/upcoming expenses] ... but that's pretty far out of
scope for 1.8.  Though a table represented in a scheme expression for
very simple lookups could easily be created.
