Effective Duration Calculator
Calculate your bond portfolio’s sensitivity to yield curve shifts with our Effective Duration Calculator.
What is the Effective Duration Calculator & How does it work?
Effective duration is a measure used in finance to determine the price sensitivity of a bond or a portfolio of bonds to changes in interest rates. It quantifies how much the bond’s price will change for a given change in yield, providing insight into the bond’s risk exposure.
The formula for effective duration is derived from Macaulay duration and takes into account the convexity of the bond. Convexity measures the curvature in the relationship between bond prices and yields, which means that the price change due to a yield shift is not linear but curved.
The formula for effective duration is derived from Macaulay duration and takes into account the convexity of the bond. Convexity measures the curvature in the relationship between bond prices and yields, which means that the price change due to a yield shift is not linear but curved.
Effective Duration = frac{P_- – P_+}{2 times P_0 times Delta y}
P_- = Price of bond with yield decreased by Ξy
P_+ = Price of bond with yield increased by Ξy
P_0 = Current price of the bond
Ξy = Change in yield
P_+ = Price of bond with yield increased by Ξy
P_0 = Current price of the bond
Ξy = Change in yield

Frequently Asked Questions
What is effective duration in finance?
Effective duration measures how much a bond's price will change for a given change in yield, considering both Macaulay duration and convexity.
How does effective duration differ from Macaulay duration?
Effective duration accounts for convexity, which means it provides a more accurate measure of price sensitivity to interest rate changes compared to Macaulay duration.
Why is convexity important in calculating effective duration?
Convexity measures the curvature in the bond's price-yield relationship, providing insight into how the bond's price will change beyond what linear duration suggests.
Can I use this calculator for a portfolio of bonds?
Yes, you can input multiple bonds to calculate the effective duration of an entire portfolio.
How do changes in interest rates affect bond prices using effective duration?
A higher effective duration indicates greater sensitivity to interest rate changes; a 1% increase in yield will result in a larger price decrease for bonds with higher durations.
Is there a limit to the number of bonds I can include in the calculator?
The calculator supports up to 20 individual bonds for portfolio analysis.
What is the formula used for effective duration?
Effective duration = Macaulay Duration + (Convexity * Yield^2) / (1 + Yield)
