Is Maine judgment interest simple or compound, and when does it start?
The rate is selected by the calendar year in which post-judgment interest begins. Section 1602-C does not specify the calculator-grade compounding, day-count, or partial-payment mechanics, so StatuteRates does not publish a Maine payoff calculator yet. Interest accrues from and after entry of judgment and includes the appeal period. A continuance longer than 30 days obtained at the prevailing party’s request suspends interest for that period, and the court may fully or partially waive interest for good cause on the nonprevailing party’s petition.
