Macaulay duration is a time measure with units in years, and really makes sense only for an instrument with fixed cash flows. For a standard bond the Macaulay duration will be between 0 and the maturity of the bond. It is equal to the maturity if and only if the bond is a zero-coupon bond.
Duration is determined by calculating the present value of the principal and each coupon and then multiplying each result by the period of time before payment is to occur. The concept of duration is used to relate the sensitivity of bond price changes to changes in interest rates. Also called mean term.
