Here is a little info from Admin regarding installment loans:
I have to check more but there is a limited # of simulations related to Installment Loans - one of them is the simulate "Refinance your mortgage". But if you don't have a mortgage, this simulation will not appear. Same goes with "Pay down your student loans". I'll see what else I can dig up.
Neither of these appear in my simulator, since I don't have a mortgage or student loan.
