Parenting time and child support for 3 children
New Hampshire's guidelines don't adjust for parenting time; courts may deviate. New Hampshire has no parenting-time formula. With approximately equal parenting time, substantially similar incomes and costs shared equally, the law presumes no support is owed; otherwise the parenting schedule is a reason the court may adjust the amount.

How the number of children changes the amount in New Hampshire
With Parent A earning $60,000 and Parent B $40,000, the guideline amount for 3 children is $1,389 a month, about 1.67 times the $833 for one child. Support rises with each child, but by less than the first child's amount, because the guidelines reflect how households share costs among children.
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.
