Interest income is a term commonly used to describe the earnings generated from the interest on deposit accounts, bonds, or other fixed-income investments. However, there are several different terms that can be used interchangeably to describe interest income. These include "income yield," "interest revenue," "interest earnings," "interest profit," and "interest returns." Regardless of the terminology used, interest income has the potential to be a valuable source of income for investors and individuals with savings accounts. With the right investment strategy, interest income can help individuals build savings, supplement retirement income, or earn passive income on their savings.
