About Compound Annual Growth Rate (CAGR)

CAGR represents the mean annual growth rate of an investment over a specified time period longer than one year. It is particularly useful when comparing investments or analyzing growth patterns over inconsistent time periods.

Key Features of CAGR
  • Smooths volatility: CAGR gives a single growth rate that would achieve the same final value, even if actual annual returns fluctuated.
  • Considers compounding: Unlike simple growth rate, CAGR accounts for the effect of compounding over time.
  • Time independent: CAGR allows for easy comparison between investments of different durations.
  • Widely used: Financial analysts, investors, and businesses use CAGR to evaluate performance of investments, sales growth, market returns, etc.
Limitations of CAGR
  • Hides volatility: CAGR doesn't show year-to-year fluctuations that might be important for risk assessment.
  • Assumes steady growth: The real-world growth path may vary significantly from the smooth curve CAGR suggests.
  • Past performance: CAGR of historical data doesn't predict future performance.
  • No consideration of additions/withdrawals: Standard CAGR doesn't account for cash flows during the investment period.
Common Uses
  • Evaluating investment performance across different time periods
  • Comparing different investments or mutual funds
  • Analyzing company revenue or earnings growth
  • Projecting future values based on historical growth rates
  • Assessing market or industry growth over time

Formula Used

CAGR = (Final Value / Initial Value)1 / Time Period - 1

Frequently Asked Questions

What is CAGR in simple terms?

CAGR is the consistent annual return rate that would turn your initial investment into the final amount over a set period. It smooths out any fluctuations that occurred along the way.

Can I use this to calculate final investment value?

Yes. Switch the calculation type to "Final Value," input your initial value, CAGR percentage, and time period, and the tool will estimate the ending amount.

How is this different from a simple interest calculator?

A simple interest calculator assumes linear growth. The CAGR Calculator uses the compound interest formula, making it more accurate for long-term investment analysis.

Does this account for additional contributions?

No, the calculator assumes no additional cash flows. It's best used when no deposits or withdrawals are made during the investment period.
