Arizona does not have one safely reusable prejudgment percentage. A.R.S. §44-1201(A) addresses qualifying medical debt, obligations, and written agreements; subsection (B) supplies the default prime-plus-one rate for nonmedical judgments; subsection (C) addresses condemnation; subsection (D) bars specified prejudgment categories; and subsection (F) directs an awarded prejudgment rate to subsection (A) or (B). The governing branch must be identified before selecting a rate.
When Arizona prejudgment interest applies
A.R.S. §44-1201(D) bars prejudgment interest on unliquidated damages and on future, punitive, or exemplary damages found by the trier of fact. When an award is permitted, subsection (F) directs the rate to subsection (A) or (B), while condemnation follows subsection (C).
When it starts accruing
A qualifying liquidated obligation generally requires a definite amount and legally relevant due date, but this page does not assign one start date to every subsection or claim. Confirm the instrument, demand, due date, and controlling authority.
Simple or compound
No universal prejudgment compounding method is stated for every §44-1201 branch. Confirm the governing agreement and authority before calculating.
How the rate is set
Subsection (F) points an allowed prejudgment award to subsection (A) or (B). Select the rate only after identifying the applicable medical-debt, obligation, written-agreement, default nonmedical-judgment, or condemnation branch.
