In Finance

Duration, in the context of fixed income investing, refers to the measure of how long it takes for an investor to be repaid a bond's price by the bond's total cash flows. It also indicates the sensitivity of a bond's or fixed income portfolio's price to changes in interest rates. Duration is a crucial metric that helps investors understand the impact of interest rate changes on bond prices. It is not to be confused with a bond's term or time to maturity, as duration is nonlinear and accelerates as the time to maturity lessens. Essentially, duration quantifies the interest rate risk associated with a bond or fixed income security.
