Legal Rate of Interest


The Legal Rate of Interest, also known as the statutory interest rate, refers to the maximum interest rate set by law that a lender can charge a borrower. The rate can vary from state to state or country to country. Asset types and purposes of the loan might also impact the applicable legal interest rate.


‘Legal Rate of Interest’ in phonetics is: /ˈliːɡəl reɪt ɒv ˈɪntrəst/

Key Takeaways

  1. Legal rate of interest is legislated: The legal rate of interest, also referred to as the statutory interest rate, is established by law. It varies by country and in the U.S., by state as well. These interest rates are generally set to regulate the amount of interest that can be charged on loans or other financial obligations.
  2. It serves to prevent usury: The legal rate of interest is a tool used to prevent usury, which is the practice of lending money at unreasonably high interest rates. It acts as a benchmark above which charges could be considered usurious, therefore providing protection to borrowers.
  3. It applies in the absence of an agreement: The legal rate of interest often applies in situations where there’s been no formally agreed upon interest rate between a borrower and lender, or in some cases, when a debt becomes overdue. The statutory rate then acts as the default interest rate.


The term “Legal Rate of Interest” is significant in business and finance because it sets the highest permissible interest rate that can be charged on loans or other types of financial arrangements. This rate is typically set by state law and is designed to protect consumers and businesses from excessively high interest rates that might be considered usurious or predatory. It serves as a regulatory measure to maintain fairness and stability in the financial market. Understanding the legal rate of interest is crucial when structuring financial agreements to ensure compliance with the law, thereby avoiding potential legal consequences. Lenders who exceed the legal rate of interest may be subject to penalties, fines, and lawsuits.


The Legal Rate of Interest is a critical tool used by governing bodies and financial institutions to control and regulate the lending practices within their jurisdiction. The primary purpose of this rate is to ensure a fair and equitable financial environment by stipulating the maximum amount of interest that can be levied on a loan or other forms of credit. Essentially, it operates as a safeguard against predatory lending practices, providing comprehensive protection to borrowers. Should a lender charge an interest rate beyond the legally established upper limit, they are likely to face severe legal repercussions. Additionally, the Legal Rate of Interest serves a broader economic role by indirectly influencing the pace of a region’s economic activities. Though not directly controlling market interest rates, it does establish a ceiling that can influence lenders’ behaviour and general market expectations. This often impacts the availability and cost of credit, which in turn can influence individual and business investment decisions, and ultimately, economic growth. In essence, the Legal Rate of Interest is not only a vital concept to maintain law and order in the financial market but also has broader macroeconomic consequences.


1. Credit Card APRs: In the United States, the legal rate of interest is determined by each state for their residents and dictates the maximum annual percentage rate (APR) that credit card companies can charge for late payments. If a credit card company charges more than the state’s established legal rate of interest, they may face penalties or legal actions. 2. Payday Loans: Payday loan vendors are often regulated by the legal rate of interest. For example, in the state of Florida, the maximum legal interest rate allowed for a payday loan is 304% per annum, whereas in states like Wisconsin, there is no limit. 3. Auto Loans: For auto loans or vehicle financing, the legal rate of interest applies. In Texas, for example, the maximum legal rate of interest is 18%. However, if the rate exceeds this limit, the creditor could potentially face charges of usury, or the illegal action or practice of lending money at unreasonably high rates of interest.
