“The definition of usury is: the illegal action or practice of lending money at unreasonably high rates of interest. Most states have usury laws or regulations.
To avoid predatory lending practices, usury laws set limits on the amounts interest that certain lenders or companies can charge. While not every lender is required to follow usury laws, it can help people identify high interest rates.
For example, in Illinois, interest rates can’t exceed 9% in a written contract, although numerous exceptions exist. Consumers can also agree to rates above the usury law, which happens more often than you’d think.
