Post-judgment interest in Arizona
An unpaid Arizona money judgment earns 8% a year unless the judgment or a contract says otherwise. On a $5,000.00 judgment that is $400.00 in the first year, about $1.10 a day.
How the rate is set
The lesser of 10% or one percentage point above the prime rate as published in the Federal Reserve's H.15 release. The judgment states its rate at entry and that rate does not change afterward. No Arizona office posts the figure; it is computed here from H.15.

Arizona is prefilled at 8%. Enter the amount and the date the judgment was entered. The calculator uses simple interest; that is how this rate accrues.
How Arizona's rate is set, and where it comes from
Uses simple interest at the rate you enter — pre-filled with each state's standard statutory rate, editable since some states publish a new rate quarterly or annually. Some states apply a different rate to specific debt types (noted above where it applies) or when a contract specifies its own rate. Informational only, not legal advice; confirm the current rate and any exceptions with your court clerk before relying on this figure.
The formula, worked
Last reviewed: October 2026
Interest = principal × rate × days ÷ 365. For $5,000.00 at 8%: $5,000.00 × 0.08000 × 365 ÷ 365 = $400.00 after one year, and $1.10 for each further day.
What this page does not know
- The rate written on your judgment. If the court stated a rate, that one applies, whatever the default is today.
- Partial payments. Interest accrues only on what is still unpaid.
- Nothing about older judgments: Arizona fixes the rate when the judgment is entered, so a judgment from an earlier period keeps that period's rate, not the one shown.
Informational only, not legal advice. Every figure is cited to the statute or the office that publishes it; confirm the current rate with the court clerk before relying on it.
