Simple Child Support Calculator
For a simple and easy calculation of child support in New Hampshire, we suggest trying the DIY Divorce Review calculator. New Hampshire appears to lack an official, government calculator that is easy to use.
The DIY Divorce Review calculator is quite simple and easy to use. But note that the estimator may not always be accurate and up to date for 2023. For a more reliable assessment, you can try the official version.
In the state of New Hampshire, the result of an online calculation should be interpreted carefully. You should treat the estimate as just a preliminary indication of the child support amount you could receive or be required to pay.
New Hampshire Parenting Time Calculator
While New Hampshire child support guidelines focus on which parent is the "custodial parent", parenting time shares have the potential to affect child support. Actual parenting time percentages could influence the order a judge makes or how much parents agree to.
Use this overnights calculator to work out your parenting time percentage. Most states measure parenting time based on overnight stays.

How Child Support is Calculated in New Hampshire
Child support payments in New Hampshire are calculated using the income shares only method. Payments depend on the combined income of the parents as well as the number of children eligible for support. A bigger combined income or extra children typically means higher payments.
The amounts transferred also depend on each parent’s income share or income percentage. New Hampshirites paying the most support are non-custodial parents with high incomes. The biggest receivers are low-income parents with primary physical custody and a high-earning payer.
We refer to the method as "income shares only" since New Hampshire lacks a well-defined way of adjusting payments for the exact amount of parenting time each parent contributes. A parent’s share of care time is not a detailed part of the guidelines, as is usually the case with income sharing models.
In New Hampshire, the Child Support Guideline calculation is presumed to be the appropriate amount, subject to a parent’s ability to argue for a support adjustment. The adjustment can be upward or downward based on the "special circumstances" of the case.
The Child Support Worksheet form is used to calculate child support. The income information is taken from the financial affidavits. Use the child support guideline worksheet available at the Superior Court or Family Division Clerk’s Office to calculate the correct support amount.New Hampshire Legal Aid
