Duration is a linear measure of how the price of a bond changes in response to interest rate changes. It is approximately equal to the percentage change in price for a given change in yield, and may be thought of as the elasticity of the bond's price with respect to discount rates. For example, for small interest rate changes, the duration is ...

Duration is a linear measure of how the price of a bond changes in response to interest rate changes. As interest rates change, the price does not change linearly, but rather is a convex function of interest rates. Convexity is a measure of the curvature of how the price of a bond changes as the interest rate changes.
The standard broker valuation formula (incorporated in the Price function in Excel or any financial calculator, such as the HP10bII) confirms this; the main term calculates the actual (dirty price), which is the total cash exchanged, less a second term which represents the amount of accrued interest.
The more curved the price function of the bond is, the more inaccurate duration is as a measure of the interest rate sensitivity. [2] Convexity is a measure of the curvature or 2nd derivative of how the price of a bond varies with interest rate, i.e. how the duration of a bond changes as the interest rate changes. [3]
Bond and Bond Price Basics Bonds have a set term; usually, a bond’s term ranges from one to 30 years. Within this time frame, there are short-term bonds (1-3 years), medium-term bonds (4-10 ...
The current yield, interest yield, income yield, flat yield, market yield, mark to market yield or running yield is a financial term used in reference to bonds and other fixed-interest securities such as gilts. It is the ratio of the annual interest payment and the bond's price:
The bond price quoted to investors is $980 plus the accrued interest. Brokers quote the dirty price, found by adding the clean price and accrued interest since that day. If the bond's last coupon payment was made on 1 June, on 1 September, the dirty price is: Clean Price + Accrued Interest (where accrued interest is the interest accumulated ...
