93 views

Effective duration can be calculated using the formula: Effective Duration = (Price if Yield Falls - Price if Yield Rises) / (2 Initial Price Change in Yield). This measures a bond's price sensitivity to changes in interest rates. Calculate price changes if yields rise or fall, then use the initial price and yield change to determine effective duration.
