New Hampshire Child Support Calculator
Estimate a monthly child support payment in New Hampshire using a national approximation.
⚠️ This is a rough educational estimate only, not legal advice. Actual child support amounts vary significantly by state guideline, court, and case specifics — consult a licensed family law attorney or New Hampshire's official child support guidelines.
How child support is calculated in New Hampshire
New Hampshire uses a Income Shares approach to its official child support guidelines. This calculator uses a simplified national approximation of the widely-used Income Shares Model (combining both parents' incomes, applying a percentage based on number of children, and splitting the obligation proportionally) regardless of which specific model your state uses, since fully replicating every state's exact worksheet is beyond the scope of a quick estimate tool.
Why this is a national approximation, not New Hampshire's exact worksheet
Since New Hampshire itself uses the Income Shares approach, this tool's underlying model is directionally consistent with your state's system — but the exact percentage tables, income caps, and additional adjustments (childcare, health insurance, extraordinary expenses) still differ from New Hampshire's official schedule.
This is a rough educational estimate only, not legal advice. For an accurate number, use New Hampshire's official child support calculator or worksheet, or consult a licensed family law attorney.
Frequently Asked Questions
What child support guideline model does New Hampshire use?
New Hampshire officially uses a Income Shares model for its child support guidelines. This calculator uses a simplified national Income Shares approximation regardless of the exact model, so treat the result as a ballpark estimate rather than the official state figure.
Is this the exact amount a New Hampshire court will order?
No. This is a rough educational estimate, not legal advice. For an accurate number, use New Hampshire's official child support worksheet or calculator, or consult a licensed family law attorney.
How does parenting time affect child support in New Hampshire?
In most states, including many using this general model, the paying parent's obligation typically decreases as their share of overnights increases above a baseline (often around 20%). This calculator applies a simplified reduction above 20% parenting time.
Does this include childcare or health insurance costs in New Hampshire?
No, this simplified calculator only estimates the base obligation from income and number of children. Many real orders in New Hampshire add separate amounts for childcare, health insurance, and extraordinary expenses on top of the base figure.
Can child support amounts be modified later in New Hampshire?
Yes, most states — including New Hampshire — allow modification when there's a significant change in either parent's income, the child's needs, or the parenting time arrangement.
Is child support based on gross or net income in New Hampshire?
Most states use gross income (before taxes) as the starting point, though some make specific deductions. This calculator treats your entries as gross monthly income.
