I live in Iowa my son father make 15 hr how would he have to pay a month for child support

First, its not a good idea to piggyback your question on another thread. To avoid confusion I moved your question to its own thread.

There are many factors involved but this site can help you get an estimate:

How many hours does he work, how much time is he with father, do you work, what is your income. Does he have other children he pays support for ?

Well because if his girlfriend he don't want to have anything to do with him. Am not sure how many hour he work. But from my understand more than 40 hr a week

Probably around 20 percent of net (income after taxes, FICA and SS are taken out) but you need him to be ordered to pay. This estimate assumes he has no other children and he is established as the father. He doesn't make much, so they may let him pay less.
