The quoted price of a bond. Adding accrued interest to the quoted price gives the so-called dirty price. The dirty price is the cash price of a bond.

For example, if accrued interest on a corporate bond is US$30, and the quoted bond price was US$ 950, then, the clean price is said to be US$950, while the dirty price is the sum of US$950 and US$ 30, which is US$ 980.
