here is how i calculate:

are you sure they’re calculating buy rate MF? also, how does the $1790 due at signing breakdown?

it doesn’t show up the breakdown, but it should be first month pay, acqusition fee, doc fee and etc.
the MF in my lease calculator is I found in edmunds forum, dealer doesn’t show up their MF anyway

Get an actual quote from the dealer instead of just taking their ad at face value. Many times they will not quote the price they advertise. It is just wasting time unless you have a formal offer
