New Hampshire Child Support Calculator – Accurate & Easy to Use

What Is the New Hampshire Child Support Calculator?

The New Hampshire Child Support Calculator is an online tool that estimates the monthly child support obligation between two parents. It considers each parent’s income, number of children, and specific costs such as childcare and health insurance.

The calculator uses data directly aligned with New Hampshire’s Child Support Guidelines, ensuring your estimate reflects state rules as closely as possible.

Key Purpose:

• Help parents understand potential payments before going to court.
• Give a realistic estimate of what support might look like under standard conditions.
• Provide transparency about how incomes and expenses affect the outcome.

How the Calculator Works

At its core, the calculator compares both parents’ monthly adjusted net incomes, determines their combined financial responsibility, and divides it based on each parent’s income share.

Here’s what it uses:

1. Parent A Net Income – The monthly income after taxes and allowable deductions.
2. Parent B Net Income – Same as above, for the other parent.
3. Number of Children – The total number of children covered by the support order.
4. Overnights with Non-Primary Parent – The number of nights per year the non-custodial parent has the children.
5. Children’s Health Insurance Premium – Monthly cost of health coverage for the children.
6. Work-Related Child Care Costs – Monthly childcare expenses related to employment.

When you click “Calculate”, the script runs through New Hampshire’s income schedule—a table that determines how much total child support should be paid based on combined income and number of children.

It then splits that total between the two parents according to their income percentages.

The result?
A clear “Estimated Monthly Payment”, showing which parent is expected to pay and roughly how much.

Example Calculation (Simplified)

Let’s say:

• Parent A Net Income: $4,000
• Parent B Net Income: $2,500
• Number of Children: 2
• Overnights with Non-Primary Parent: 100
• Health Insurance: $100
• Child Care: $200

The calculator:

1. Combines incomes ($6,500).
2. Finds the base support from the state’s schedule for two children.
3. Adds the extra costs (health + childcare).
4. Divides the total based on each parent’s income share.

If Parent A earns more, they might be responsible for a larger percentage. But if the overnights are more evenly split, the obligation may adjust accordingly.

Why Overnights Matter

In New Hampshire, parenting time plays a major role in determining support.

• If one parent has the child more than half the time (more than 182 overnights), they’re considered the primary parent.
• The parent with fewer overnights typically becomes the obligor (payer).

The calculator reflects this by automatically switching which parent pays based on overnight entries.

Factors That Affect Child Support in New Hampshire

While this calculator gives a solid estimate, real-life child support orders can differ based on:

1. Parenting Schedule Adjustments – Courts can modify support if parenting time changes significantly.
2. Special Needs or Education Costs – If a child has medical or educational needs, payments can increase.
3. Extraordinary Income Situations – For very high or very low incomes, judges may deviate from the guideline.
4. Shared or Split Custody – Each case is different, and exact obligations depend on how time and expenses are divided.

Important Disclaimer

The calculator provides an estimate only.
It’s based on New Hampshire’s Child Support Guidelines and common assumptions, but it’s not a legal determination.

Final child support amounts are decided by the court and may vary depending on parenting arrangements, other income sources, and unique case details.

If you need specific legal advice, consult a family law attorney familiar with New Hampshire regulations.
