Question: how much child support do fathers pay?
Answer: Depending on the state where he lives, a father must pay 15 percent to 20 percent of his pretax income (20 percent to 25 percent, or more, after-tax) as child support for one child. This usually goes to 25 percent to 35 percent pretax (30 percent to 40 percent, or more, after-tax) because there is more than one child.
