Nevada statutory interest, cited to the source.

The two regimes

Before July 1, 1987 the statutory rate was a flat percentage that did not reset and stayed fixed for the life of an obligation by its arising date. The 1987 Legislature replaced it with the resetting prime + 2% formula, which - by its own terms - applies only to causes of action arising on or after July 1, 1987. An obligation that arose earlier keeps its flat rate for life.

Governing authority

NRS 99.040(1)Interest on money owed absent an express contract

Sets the base rate: since July 1, 1987, the prime rate at Nevada's largest bank as ascertained by the Commissioner of Financial Institutions on the preceding January 1 or July 1, plus 2%, adjusted each January 1 and July 1.

NRS 17.130(2)Interest on judgments

Carries the same prime + 2% rate for judgments, from the time of service of the summons and complaint. Moved in lockstep with NRS 99.040 through every amendment.

NRS 125B.140(2)(c)(1)Interest on child-support arrearages

Each unpaid support installment carries interest at the NRS 99.040 rate from the time it became due. Each installment becomes a judgment by operation of law on its due date (NRS 125B.140(1)(a)).
