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.
