I am dealing with this same dilemma at this very moment. I would have thought Appdx D would come into play for APR calculation, but it doesn't appear to.
When I produce a note/Reg Z for a closed end LOC [and yes, our system calls it exactly that] it calculates an APR with an (e), a Finance charge which is in the neighborhood of 1/2 of what the full balance would be plus fee. It does not disclose an estimated monthly interest payment, it just says [blank] number of payments [blank] amount of payments [when due] interest on the amount of credit outstanding will be paid monthly.
And 1 payment of the full principal plus a little more than one month's interest. I can't quickly come up with how this was final payment was calculated . Of course everything in the FED box except the amount financed does contain (e).
Does this sound remotely right?
