When you need to evaluate the average annualized return of an investment over multiple years, a Compound Annual Growth Rate (CAGR) calculator eliminates the noise of annual volatility to provide a smoothed growth trend analysis. This tool uses the formula CAGR = (FV/PV)(1/n) - 1 to calculate the average annual compound growth rate of an asset from its present value (PV) to its future value (FV) over n years, outputting the annualized return as a percentage.
Q: Can the initial or final value be zero?
A: The initial value must be greater than zero. The final value can be zero (indicating a total loss), but a zero initial value will cause a divide-by-zero error.
Q: What is the difference between CAGR and the simple average growth rate?
A: CAGR uses a geometric mean, accounting for the compounding effect. A simple average uses an arithmetic mean, which can overstate actual returns. For example, if a 10,000 investment grows by 50% in year one (15,000) and drops by 33% in year two (back to 10,000), the simple average shows an 8.5% return, but the CAGR is 0%, which accurately reflects the true outcome.
The initial value must be a positive number, and the number of years should be an integer ≥ 1. The result only reflects a theoretical average growth rate; actual annual returns may fluctuate. Please ensure browser privacy and security when handling sensitive financial data.
For non-integer investment periods, you can convert months into years (e.g., 30 months = 2.5 years). A typical example: an initial investment of 10,000 grows to 16,105 over 5 years, corresponding to a CAGR of 10%. When comparing investments with different time horizons, it is recommended to use CAGR rather than total return. For instance, an 80% return over 3 years (CAGR = 21.64%) is actually better than a 100% return over 5 years (CAGR = 14.87%).
