1. What is CAGR?

CAGR (Compound Annual Growth Rate) is the mean annual growth rate of an investment over a specified period of time longer than one year. It represents one of the most accurate ways to calculate and determine returns for anything that can rise or fall in value over time.

2. How Does the Calculator Work?

The calculator uses the CAGR formula:

\[ CAGR = \left( \left( \frac{\text{End Value}}{\text{Start Value}} \right)^{\frac{1}{n}} - 1 \right) \times 100 \]

Where:

\( \text{End Value} \) — Final value of the investment
\( \text{Start Value} \) — Initial value of the investment
\( n \) — Number of years

Explanation: The formula calculates the constant rate of return that would be required for an investment to grow from its beginning balance to its ending balance, assuming profits were reinvested at the end of each period.

3. Importance of CAGR Calculation

Details: CAGR is widely used to compare the historical returns of different investments, assess business growth rates, and make investment decisions. It smooths out the volatility of periodic returns to provide a clearer picture of long-term performance.

4. Using the Calculator

Tips: Enter the starting value and ending value in any currency, and specify the number of years. All values must be positive numbers (start value > 0, end value > 0, years ≥ 1).

5. Frequently Asked Questions (FAQ)

Q1: What is a good CAGR percentage?
A: A "good" CAGR depends on the investment type and market conditions. Generally, 7-10% is considered good for stock investments, while higher percentages indicate exceptional growth.

Q2: How is CAGR different from average annual return?
A: CAGR accounts for compounding effect, while average annual return simply averages the yearly returns. CAGR provides a more accurate representation of investment growth.

Q3: Can CAGR be negative?
A: Yes, if the investment loses value over the period, CAGR will be negative, indicating an annualized loss.

Q4: What are the limitations of CAGR?
A: CAGR assumes smooth, consistent growth and doesn't account for volatility or the timing of cash flows. It may not reflect the actual year-to-year performance.

Q5: How can I use CAGR for investment planning?
A: CAGR helps project future investment values and compare different investment opportunities to make informed financial decisions.
