How to define interest expense. Interest is the fee that we pay to a lender, for the use of his money, over a period of time. Let's say we borrow a hundred thousand dollars, to buy a machine, and the quoted interest rate is prime, or prime plus one. Five, six, seven percent, whatever the number might be in a given situation, and we pay that interest rate for the time that we use the money. Let us say one year, seven percent, the interest expense is seven thousand dollars, for the use of one hundred thousand dollars, for one year.
