CAGR Calculator

What This Calculator Estimates

Compound Annual Growth Rate (CAGR) smooths out an investment's returns over a period into a single annualized growth rate, useful for comparing the performance of different investments over time even if their year-to-year returns were volatile. This calculator computes CAGR using your beginning value, ending value, and number of years, giving a single representative growth rate figure for that period.

How to Use This Calculator

  1. Enter the starting value.
  2. Enter the ending value.
  3. Enter the number of years.
  4. Click Estimate CAGR.
  5. Review the annualized growth estimate.

Frequently Asked Questions

What does CAGR actually represent?

CAGR represents the constant annual growth rate that would take an investment from its beginning value to its ending value over the specified period, smoothing out any year-to-year volatility into a single figure.

Why is CAGR useful for comparing investments?

Since CAGR provides a single annualized figure, it makes comparing investments with different volatility patterns or time periods more straightforward than looking at raw total returns or year-by-year figures.

Does CAGR reflect actual year-to-year volatility?

No, CAGR is a smoothed average — an investment could have had very volatile individual years yet still show a steady-looking CAGR over the full period, so it doesn't capture risk or volatility on its own.

Is CAGR the same as average annual return?

Not exactly — CAGR is a compound (geometric) growth rate, while simple average annual return is an arithmetic mean of yearly returns, and these can differ meaningfully, especially with volatile returns.

Can CAGR be negative?

Yes, if the ending value is lower than the beginning value, CAGR will be negative, reflecting an overall decline in value over the period despite it being an annualized calculation.
