Real-World Example: Assessing Bond Portfolio Risk

Scenario

An investor holds a bond portfolio and wants to understand how a 1% increase in interest rates will affect its value. The portfolio's initial price is $1,000,000. If rates rise, the price is expected to be $950,000, and if they fall, $1,050,000.

Outcome

The calculator shows an effective duration of 5 years, meaning the portfolio's value is expected to decrease by approximately 5% for every 1% increase in interest rates, helping the investor quantify their risk exposure.
