**Introduction:** The Compound Annual Growth Rate (CAGR) is a crucial metric for assessing the annual growth rate of an investment over a specified period. This calculator provides a simple way to calculate CAGR over a 3-year duration.

**Formula:** The formula for calculating CAGR is `(Final Value / Initial Value)^(1 / Number of Years) - 1`

. This formula represents the geometric progression between the initial and final values.

**How to Use:**

- Enter the initial value of the investment.
- Enter the final value of the investment.
- Enter the number of years for the investment period (in this case, 3 years).
- Click the “Calculate CAGR” button to get the result.

**Example:** Suppose the initial value is $10,000, the final value is $13,000, and the investment period is 3 years. The calculator would output “Compound Annual Growth Rate (CAGR): 8.48%.”

**FAQs:**

**Q: Can I use this calculator for periods other than 3 years?**A: Yes, you can enter the desired number of years to calculate CAGR for different periods.**Q: How is CAGR different from simple annual growth rate?**A: CAGR considers the compounding effect, providing a more accurate representation of annual growth over a period.**Q: What does a negative CAGR indicate?**A: A negative CAGR implies a negative growth rate or a decline in the investment value over the specified period.**Q: Is CAGR suitable for all types of investments?**A: CAGR is particularly useful for assessing the growth of investments with varying annual returns.**Q: Can CAGR be used for non-financial metrics?**A: Yes, CAGR can be applied to any metric that experiences growth over time, not just financial investments.

Understanding CAGR is valuable for investors and businesses to assess the true annual growth rate and make informed decisions based on historical performance.
