What Is a Legal Rate of Interest?

A legal rate of interest is the highest rate of interest that can be legally charged on any type of debt, for which a lender must adhere to. The legal rate of interest applies to all types of debt, although certain types of debt may carry a higher legal rate than another – for instance, the legal limit on a payday lender may be higher than the legal limit on a student loan. The limit is set to prevent lenders from charging borrowers excessive interest rates.

The Legal Rate of Interest Explained

An interest rate that exceeds the legal rate of interest is classified as usury. There are usually stiff penalties for usury in most states, such as fines or even the forfeiture of principal and/or interest. The legal rate of interest can also be classified as the highest rate that lenders can charge for any legal claim that can be enforced in a court of law.

In the United States, individual states are responsible for setting their own interest rate laws. Though this type of financial activity could fall under the Constitution's commerce clause, Congress has not traditionally focused on usury. The government does consider the collection of interest payments through violent means a federal offense.

Key Takeaways

  • The legal rate of interest is the highest amount of interest a lender can charge a borrower on a debt.
  • The legal rate of interest will differ based on jurisdiction – in the U.S. each state defines its own legal interest rate.
  • The legal rate of interest is related to the practice of usury and usury laws.

How the Legal Rate of Interest Is Applied in Different Jurisdictions

Each state may set a legal rate of interest through their respective laws. For example, New York set its legal rate of interest at 9%. Delaware’s legal rate of interest is 5% above the Federal Reserve rate, which makes it subject to fluctuations.

In addition to these limits, each state typically sets separate general usury limits that may be higher. New York’s limit is 16% for civil usury and 25% for criminal usury. Banks and other providers of financing who do business in a state could be subject to that jurisdiction’s legal rate of interest.

There are certain exceptions and circumstances that may let lenders charge rates in excess of a jurisdiction’s legal rate of interest. Customers can choose to waive this protection when they apply for financing. Many lenders and financiers may require such an agreement to be signed by their customers in order to receive any financing.

The language that grants the company the right to charge higher interest rates may be included in the terms of service. Agreeing to receive financing at the interest rate assigned by the lender could override the protections that a legal rate of interest offer, whether or not the customer later attests to fully understanding her rights.

Circumventing the Legal Rate of Interest

Lenders might be able to bypass a legal rate of interest through similar methods used to circumvent usury laws. For instance, credit card providers are allowed to charge interest rates based on the state where the company is incorporated rather than the states where their customers live. The lender might choose to incorporate in a state such as Delaware that offers more relaxed usury laws than other states typically offer.

Credit card companies typically have the benefit of being able to charge interest rates that are allowed by the state where the company was incorporated rather than follow the usury laws that apply in the states where borrowers live. Nationally chartered banks similarly can apply the highest interested allowed by the state where the institution was incorporated. By incorporating in states such as Delaware or South Dakota, such lenders have historically benefited from greater leeway allowed by those states’ relaxed usury laws.
