Iowa Code §§535.3 and 668.13 set the general noncontract judgment rate at the one-year Treasury constant maturity selected from Federal Reserve H.15, plus 2 percentage points. State Court Administration publishes the applicable selection in a monthly table; it is not the federal court system’s weekly-average rate. The rate is selected as of judgment and interest is computed daily. A qualifying contract rate, workers’ compensation award, support obligation, or structured judgment can follow a different rule.
How Iowa post-judgment interest works
Which rate applies
The headline applies to the general noncontract path under §§535.3(1)(a) and 668.13. If a contract fixes a lawful rate, §668.13(2) uses that rate subject to the §535.2 cap. Section 535.3 separately addresses workers’ compensation and child, spousal, and medical-support obligations.
When interest accrues
Section 668.13 generally allows interest from commencement of the action, with future damages beginning only when judgment is entered. After entry, the rate selected as of the judgment continues while the amount remains unpaid. Section 625.21 also supplies a verdict-to-final-entry rule outside chapter 668.
Compounding and rate lock
Section 668.13(5) requires interest to be computed daily to payment, and Iowa authority treats the ordinary path as simple interest. The statute does not itself state the annual day-count denominator or every partial-payment rule, so the calculator remains withheld.
Official history coverage
The dataset contains 303 exact Judicial Branch table selections from March 2001 through August 10, 2026, including the current 6.06% selection. The official 1982–2000 scan is linked but not digitized because damaged and handwritten rows need a second manual check. If the live table is temporarily blocked, automation retains the last verified court history instead of substituting an estimate.
