New Hampshire Child Support and Parenting Time Totals
In New Hampshire, the amount of child support is figured based on a percentage of both parents' combined income, and parenting time doesn't factor into the formula.
New Hampshire uses a basic child support formula that uses both parents' combined income to determine the amount of payment. Accurate parenting time numbers can affect your child support, whether you pay or receive. You can use the calculator above to estimate your child support amount.
Most parenting time totals are estimates (and thus incorrect)
New Hampshire lawyers and judges often rely on parenting time estimates, even if they are incorrect, because counting parenting time is tedious and time consuming. Divorcing parents often rely on these estimates as well.
Using estimates means your parenting time totals are wrong when compared to your actual parenting time schedule. Keep your parenting time fair and exact with accurate records.
How to calculate parenting time instead of relying on estimates
To calculate parenting time, the easiest and most accurate way is to use software. Without software, you're forced to add up hours for a whole year, which is error-prone when you include alternating holidays, summer break, and any changes to the schedule throughout the year.
Using software, you can also tweak your schedule to see how even little changes affect your total parenting time, and you can see how your parenting time changes each year due to holidays and other events.
You can also track what actually happens, and show how much parenting time you've actually received for any period of time. Historical information is a powerful tool when you request a child support modification or when you request more parenting time.
Fast facts about New Hampshire child support
In a New Hampshire physical custody case, the family court may designate a primary physical custodian. The residential parent hosts the children the majority of the time. The nonresidential parent has visitation time.
A New Hampshire family court awards joint decision-making to most cases, except where the children's best interests or a parent's health or safety are an issue.
New Hampshire family courts must comply with the child support guidelines as specified in the statute, but a court has the right to deviate. According to New Hampshire law, 458-C:5, a deviation is allowed in the case of "ongoing extraordinary medical, dental or education expenses, including expenses related to the special needs of a child."
New Hampshire child support formula and parenting time totals
In New Hampshire, the child support formula starts with both parents' combined net income, then considers the number of children to support. For example, if the parents' combined net income is over $125,000 a year:
| Number of children | % of combined income |
|---|---|
| 1 | 19% |
| 2 | 26% |
| 3 | 31% |
| 4 | 33.5% |
This amount will be divided between the parents in proportion to their incomes. The parent with less parenting time pays the other.
If you have similar incomes or similar parenting time
Beginning in 2025, New Hampshire considers your parenting time split. This makes it important to write a parenting schedule.
| Parenting time | Substantially similar incomes | Incomes differ by more than 10% |
|---|---|---|
| Equal or near-equal | Court presumes: No child support order | May deviate from guidelines. Will consider if both parents can financially meet the child's needs in "similar or approximately equal style." |
| "Substantially shared" | Court presumes: Deviate from guidelines | Same as above |
| Unequal | — | Court presumes: Use guidelines to calculate |
These court presumptions are rebuttable, meaning you can argue for why they should not apply to you. The court can also make adjustments in the best interests of the children.
Why accurate parenting time percentages are important in New Hampshire
Accurate parenting time percentages are important because New Hampshire law, 458-C:5, allows for certain exceptions to be made in the child support amount if you can show you qualify for special consideration.
The law states that the court may deviate from the standard child support guidelines when it finds "reasonable expenses incurred by the obligor parent in exercising parental rights and responsibilities." This could include instances where the nonresidential parent hosts the children for overnights that far exceed a standard parenting time schedule.
While this scenario is rare, at least you can present the court with accurate parenting time numbers.
Other factors in the New Hampshire child support formula
New Hampshire's child support formula uses the following information to calculate your monthly amounts for joint custody child support:
- The number of children who are under 18 or still in high school.
- Certain deduction amounts, such as the cost of health insurance premiums for the children or the cost of child care.
- A pre-existing child support or alimony obligation by either parent.
How accurate child support helps your children
Paying accurate child support helps your children in several ways, primarily because it ensures their financial needs are met.
More reasons why accurate overnight numbers help you, the other parent and your children:
- It provides a fair way to determine your child support amounts.
- It guarantees the child support amount reflects each parent's responsibilities.
- It allows for modifications if your actual time and scheduled time are different.
- It is compliant with New Hampshire law.
Your financial obligations to your children don't end with divorce, so whether you are paying or receiving child support, you owe it to your children to pay or receive the proper amount.
