How the number of children changes the amount in New Hampshire

For one child, the guideline amount ranges from $50 a month when Parent A earns $20,000 to $2,851 a month at $250,000, with Parent B earning $40,000.

New Hampshire applies a percentage to the parents' combined net income: from 25.6% down to 19% for one child as income rises, and from 45% down to 33.5% for four or more children. The state's table builds the net income in, so you enter gross income. Each parent is responsible for their share of the table amount, and the parent the children don't live with pays theirs.
