## simple interest - Investment & Finance Definition

Interest that is paid only on the original principal or on the amount originally borrowed. Interest earned or interest charges are not included in future calculations. Because of this, the amount of interest earned, or owed, in the case of a loan, will be less than with a calculation that uses compound interest. See also compound interest.
