01 What is CAGR?

CAGR, or Compound Annual Growth Rate, is a financial metric used to measure the average annual growth rate of an investment over a specific period. The Compound Annual Growth Rate (CAGR) is a more precise way to measure an investment's performance than just looking at the total return. This is due to the fact that CAGR is a consistent rate of return that considers the reinvestment of an investment's profits year after year.

The CAGR calculator is a useful tool for any trader who wants to easily estimate the gains and growth rate of their investments over some time.

02 Calculating the CAGR

To calculate CAGR, the following variables are required: the beginning value (or present value), the ending value, and the number of years (N). The following CAGR formula is used to calculate the values:

CAGR = (Ending Value /Beginning Value)^1/N - 1

For example, let's say the initial value of your investment is $10,000, and the ending value is $21,000 in four years (N=4 years). Next up, we will use the mathematical formula to calculate the CAGR.

CAGR = ( 21000 / 10000 )^1/4 - 1 = 16.93%

Compound Growth Matters

Now that we have showed you how to calculate the compound annual growth rate, let's explore what happens if there are different financial parameters in play. For the sake of the next example, let's assume you have invested $15,000, five years ago and you want to know what the CAGR (investment performance) was each year.

Initial value	Final value	No. of years	CAGR
$10,000	$12,000	5	3.714%
$10,000	$14,000	5	6.961%
$10,000	$16,000	5	9.856%
$10,000	$18,000	5	12.475%
$10,000	$20,000	5	14.870%

Next, let's calculate how the CAGR of your initial investment of $15,000 would change over different periods of time. For the sake of our example, we'll use the period of 2,4,8 & 10 years to calculate the future value.

Initial value	Final value	No. of years	CAGR
$10,000	$20,000	2	3.714%
$10,000	$20,000	5	6.961%
$10,000	$20,000	8	9.856%
$10,000	$20,000	10	12.475%

What are the benefits of using CAGR?

Some of the benefits of using a CAGR calculator include:

Accuracy

CAGR offers a precise measurement of an investment's performance by considering the compounded annual growth rate. This is in contrast to simpler methods that might only look at the total return, which can be misleading due to volatility and varying time periods. CAGR accounts for the time value of money and provides a more realistic picture of how an investment has grown on an annualized basis.

Consistency

Investment returns can fluctuate significantly from year to year due to market conditions, economic changes, and other factors. CAGR smooths out these variations by providing a consistent, average rate of return over the investment period. This allows for a more stable and reliable assessment of performance, making it easier to compare investments with different return patterns.

Comparability

CAGR allows for straightforward comparison of different investments' performance over the same time period. This is because it standardizes the returns into an annualized growth rate, regardless of the actual investment duration or the timing of cash flows. This makes it easier to evaluate and choose between various investment options, as it provides a common benchmark for comparison.

What are the Limitations of CAGR?

Some of the limitations of using a CAGR calculator include:

Volatility

CAGR smooths average growth but ignores price fluctuations during the period. Two investments with the same CAGR could have vastly different risk levels. This matters for risk-averse investors who need to understand the ride, not just the destination.

Past Performance

CAGR relies entirely on historical data. It does not predict future performance, which is influenced by shifting markets, economic changes, or company events. It’s a rear-view mirror, not a forecast.

Simplicity

While easy to understand, CAGR doesn't account for taxes, fees, dividends, or inflation. These factors can significantly change your real-world returns and aren’t reflected in the raw CAGR number.

External Factors

CAGR doesn't include impacts from geopolitical tensions, interest rate shifts, or recessions. It assumes a controlled world, which is rarely the case for long-term investments.

Distribution Timing

CAGR assumes steady compounding, but real returns may be front- or back-loaded. This skews the perceived growth and doesn’t reflect how timing affects final investment value.

Comparison Issues

CAGR helps compare investments but not always fairly. Different asset classes, risk profiles, or strategies can’t be fully judged by CAGR alone — it oversimplifies complex performance landscapes.
