WebIn the market, bond prices are quoted as a percent of the bond’s face value. The easiest way to understand bond prices is to add a zero to the price quoted in the market. For example, if a bond is quoted at 99 in the market, the price is $990 for every $1,000 of face value and the bond is said to be trading at a discount.
