For Bond 1, the duration formula entered in cell B19 is: =DURATION(B2,B3,B5,B6,B9,B10) We then copied this formula to C19 to find the duration of Bond 2. When the bond reaches maturity, its investor receives its face value. For example, if the duration of a bond is 3, … Now let's jump forward. To account for the fact that bond prices are negative … Effective Duration is a measure of the interest rate sensitivity of the price of the instrument to small changes in the interests. If a bond is continuously compounded, the Modified duration of the bond equals the Macaulay duration. So, it essentially shows that if the interest rate in the market moves by 1%, then the bond price would move by the value of modified duration in the opposite direction. In reality, interest rate vary with maturity i.e. As a simple example, let’s say you have a bond with a duration of five years. Therefore, in our example above, if interest rates were to fall by 1%, the 10-year bond with a duration of just under 9 years would rise in value by approximately 9%. The modified duration alone underestimates the gain to be 2.45%. A zero-coupon bond is a bond bought at a price lower than its face value, with the face value repaid at the time of maturity. A bond’s price and duration have an inverse relationship. Using a financial calculator to calculate yield is easy. Bond duration is a way of measuring how much bond prices are likely to change if and when interest rates move. A pension scheme holds a large position in a 6.5% annual coupon payment government bond that matures on 10th March 2034. Therefore, if a bond has a duration of 5 years, it signifies that fo 1 r every 1% increase in the interest rate, the price of the bond will fall by 5% and vice-a-versa. Bond Present Value Calculator Bond Yield to Maturity Calculator Zero Coupon Bond Value Calculator Zero-coupon bonds are popular (in exams) due to their computational convenience. Further, we will set (note that since the calculator requires i to be in percent, you will need to multiply this by 100) . Security specification. So if the modified duration of a bond is 10 years and interest rates go down by 1%, then the bond price will increase by 10%. Thus, any coupon bond can be treated as a zero-coupon bond, with the maturity and hence duration of the zero-coupon bond being equal to the coupon bond’s duration. So, for example, a 5-year, zero-coupon bond has a 4-year key rate duration of −0.1633 years; if the 4-year par rate increases by 1%, the price of the bond will increase by approximately 0.1633%. In this exercise, you will calculate the approximate duration of a bond with $100 par value, 10% coupon rate, 20 years to maturity, 10% yield to maturity, and a 1% expected change in yield. Use this calculator to compute the convexity, Macaulay duration and current price of a bond. The Duration of a zero-coupon bond is the number of years until maturity. In the example shown, we want to calculate the duration of a bond with an annual coupon rate of 5% and semi-annual payments. For instance the duration of a floating rate bond with a spread of 1% over ie libor is equivalent to the duration of any fixed cashflows (ie ones on or before the refix date like you have mentioned) plus the duration of a fixed coupon bond with coupon 1% going out to maturity. You would enter: "1,000" as the face value "8" as the annual coupon rate "5" as the years to maturity "2" as the coupon payments per year, and "900" as the current bond price. For example, a bond with 10 years till maturity and a 7% coupon trading at par to yield 7% has a duration of 7.355 years. If interest rates somehow increase by 2%, the same bond’s price would decrease by 10%. the sum of the present values of all of the cash flows) is a number between 0 and 1 which sum to 1.
