The formula for the duration is a measure of a bond’s sensitivity to changes in the interest rate, and it is calculated by dividing the sum product of discounted future cash inflow of the bond and a corresponding number of years by a sum of the discounted future cash inflow.

Why do we calculate duration of a bond?
Bond duration is a way of measuring how much bond prices are likely to change if and when interest rates move. In more technical terms, bond duration is measurement of interest rate risk. Understanding bond duration can help investors determine how bonds fit in to a broader investment portfolio.

Duration and Risk
Table 1 below compares measures of duration for bonds with maturities varying from 1 year to 30 years. Duration is based on 8% par fixed-coupon bonds. We observe that duration is increasing with maturity: the duration of a 5-year note is 4.0 years, and that of a 30-year bond is 11.3 years.
What is the duration of a 10 year Treasury bond?
The 10-year Treasury note is a debt obligation issued by the United States government with a maturity of 10 years upon initial issuance. A 10-year Treasury note pays interest at a fixed rate once every six months and pays the face value to the holder at maturity.
How do you calculate duration of a bond portfolio?
There are two methods for calculating the duration of a bond portfolio: the weighted average of time to receipt of the aggregate cash flows; and. the weighted average of the individual bond durations comprising the portfolio.
The bond portfolio’s modified duration is closest to:
- 6.55.
- 7.54.
- 7.88.
How do you approximate duration?
duration = dollar duration/price = -p'(y) /p(y) ≈ – percent change in price for 100 bp change in bond yield. This gives the similar formulas as before, except that the security’s yield replaces the zero rates. Yield duration gives the percent change in price for a 100 bp change in the bond’s yield.
How does hp12c calculate bond duration?
It is important to note that these equations work only on an interest payment date.
How to Calculate Duration and Convexity of a Bond on the HP 12C.

How do you calculate duration and modified duration?
To find the modified duration, all an investor needs to do is take the Macaulay duration and divide it by 1 + (yield-to-maturity / number of coupon periods per year). In this example that calculation would be 2.753 / (1.05 / 1), or 2.62%.
How do you calculate duration of a bond portfolio in Excel?

How do you calculate duration in physics?
To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
What is the duration of a coupon bond?
The duration of a zero-coupon bond equals time to maturity. Holding maturity constant, a bond’s duration is lower when the coupon rate is higher, because of the impact of early higher coupon payments. Holding the coupon rate constant, a bond’s duration generally increases with time to maturity.
How is duration calculated in project management?
If everyone worked eight hours per day on your project, and was absolutely 100% productive for all eight hours, you could easily calculate duration by taking the number of effort hours, divided by the number of resources, divided by the number of hours they work per day.

What is the duration of a 5-year bond?
