Title XIII (Commerce), Subtitle 3 (Money and Credit), Chapter 535 regulates the rates of interest in the state of Iowa. Section 535.2 prescribes that the rate of interest as five percent per year i.e., five cents on the hundred by the year. The maximum lawful rate of interest that parties can agree upon in writing shall be two percentage points above the monthly average ten-year constant maturity interest rate of United States government notes and bonds as published by the board of governors of the federal reserve system.
Section 535.4 prescribes that no person shall charge a greater rate of interest than actually prescribed in the Chapter. By the authority of Section 535.5, a person who has paid an increased interest amount may have judgment only for principal sum remaining unpaid without interest or costs; forfeiture of eight percent by the year upon the amount of the principal remaining unpaid at time of judgment.
Interest on judgment is fixed pursuant to Section 535.3 as ten percent per annum. Section 668.13 of Iowa Code prescribes rate of interest on judgment or decree, which is based on a contract, as the rate expressed in the contract. But this rate shall not exceed the maximum rate prescribed otherwise by law.
Certain exceptions to the usury penalty are:
- Loans for acquiring real property or refinancing a contract for deed,
- Loans more than $25,000, excluding interest, for improvement on real property, or
- Loans more than $25,000 for business or agricultural or household purposes
