This question illustrates what somewhat unscrupulous lender. You want to borrow $29,000 for one year. The interest rate is 19.5 percent. You lender agree that the interest on the loan will be .195x $29,000 $5,655. So, the lender deducts this interest amount from the loan up front and gives you $23,345. In this case, we say that the discount is known as discount interest. Imagine you are discussing a loan with $5.655.
