my grandmothers was about 7k in 2007 BUT plot and gravestone and burial were paid for by the govt since she was burined at a national cemetary (my grandfather was in the army) my mom's cremation was about 3200$ my dad was donated to science and ashes returned about 4 wks later at a cost of 190$ out of pocket that does not include his "going away dinner" which was about 700$ including bounce house for the kids..

Although my mom did tell me that if we want to go ahead and pay for our plots at the family cemetery before we die, since they secured the plots before 1985, we can pay $500 (I think) and be set forever. That includes opening and closing and all upkeep forever for our two plots.
It's probably just a story to keep the kids from using the fields around the cemetery for making out or drinking, but I kind of like the idea of getting to be buried in a haunted cemetery!)
