The amount of American goulash per person depends on the size of your group.  Generally, a single serving is about 1 to 1 ½ cups, so if you are feeding four people, then plan to make 6 to 9 cups total.  If you are feeding more than four people, you may need to double or triple the recipe to accommodate everyone. It's important to make sure that there is enough for everyone and that no one goes hungry!
