One-child base rate at New Hampshire's median income
19% of $88,465, the Census ACS 2022 median household income for New Hampshire, divided across twelve months, 47% above the median state. An index for comparing states, not a case estimate: guidelines apply to the obligor's income, or to combined parental income under the Income Shares model, and a court sets the actual order.

Smaller Title IV-D caseload
28,629 active cases put New Hampshire in the lightest third by OCSE P-52 volume (#48).
New Hampshire carries 28,629 Title IV-D cases - a light-third book on OCSE P-52 volume. The Income Shares schedule (43 jurisdictions on this model) opens higher than most peers before deviations. Unlike capped states, the formula applies to full reported income before deductions. Nearest one-child rate peer: Colorado at 19% (Δ 0.0 pts). New Hampshire also builds a parenting-time credit into the guideline - relevant when a dense order book meets substantial overnight time.

New Hampshire uses the Income Shares model. Both parents' incomes are combined, the total obligation is looked up from a schedule, then split proportionally based on each parent's income share. Its one-child base rate is in line with the national middle range. That higher-third starting rate is the schedule's open before deviations.
