Interest accrues automatically, but the rate changes yearly
The New Hampshire Supreme Court has held that statutory interest accrues on child-support arrearages and is not optional for the trial court.
RSA 336:1(II) sets a simple judgment rate from the 26-week Treasury-bill rate plus two points. The State Treasurer resets it for each calendar year.
A multi-year balance therefore needs each missed installment, every payment, and each applicable annual rate. The calculator leaves the numeric rate blank until the current official rate notice is confirmed.
Use the year-by-year official ledger
A single rate applied to one principal would misstate a multi-year balance. Obtain the calendar-year rates, installment history, payments, and any BCSS adjustment.
