The average effective maturity is the weighted average of the maturities of all the bonds in a portfolio. The weighting is based on the size of each bond's market value. The average effective maturity is used to measure the sensitivity of a bond portfolio's value to changes in interest rates.

##### What is the difference between duration and effective duration?

Duration is a measure of the sensitivity of the price of a bond to changes in interest rates. It is used as a measure of the price risk of a bond. Effective duration is a measure of the sensitivity of the price of a bond to changes in interest rates that takes into account the effect of interest rate changes on the cash flows of the bond.

What is the difference between average maturity and duration? These two terms are often used interchangeably, but there is a subtle difference. Average maturity is the weighted average of the maturity dates of all the bonds in a portfolio. Duration is a measure of a bond's sensitivity to changes in interest rates. It is a weighted average of the time to each cash flow, with the weights being the present value of the cash flow divided by the total present value.

#### How do you calculate effective maturity?

To calculate effective maturity, first identify the maturity date of the bond and the frequency of coupon payments. Then, using a discount rate, calculate the present value of all future cash flows. The effective maturity is the length of time it would take for the bond's price to return to its par value, given the current yield. What is the difference between average maturity and modified duration? Average maturity is a measure of the weighted average time to maturity of all the bonds in a portfolio. Modified duration is a measure of a bond's price sensitivity to changes in interest rates.

##### How do you calculate bond maturity?

Bond maturity is the date on which the issuer of a bond must repay the principal amount of the loan to the bondholder. The maturity date is typically stated in the bond contract.

To calculate the maturity date, first determine the issue date of the bond. This is the date on which the bond was issued and is typically stated in the bond contract. Next, add the term of the bond to the issue date. The term is the length of time until the bond matures, and is typically stated in years. For example, if a bond has a term of 10 years and was issued on January 1, 2020, the maturity date would be January 1, 2030.

If interest payments are made semi-annually, then the maturity date will be six months after the last interest payment is made. For example, if a bond has a term of 10 years and was issued on January 1, 2020, the maturity date would be July 1, 2030.
