Compound Annual Growth Rate (CAGR)

Compound Annual Growth Rate (CAGR) is the annualized rate at which an investment, revenue stream, earnings figure, or other financial value would have grown if it increased at a constant compounded rate from its beginning value to its ending value.

CAGR smooths a multi-year result into a single annual growth rate.

It is commonly used to measure:

• Investment growth
• Revenue growth
• Earnings growth
• Free cash flow growth
• Dividend growth
• Portfolio performance
• Business expansion over time

CAGR does not show the actual year-by-year path. It shows the constant annual rate that would connect the starting value to the ending value.

Why CAGR Matters

CAGR helps investors answer:

“At what compounded annual rate did this value grow over the period?”

That makes it useful for comparing companies, investments, and financial metrics measured over different time spans.

For example, suppose revenue grows from $500 million to $800 million over five years.

Rather than simply saying revenue increased 60%, CAGR converts that growth into an annualized compounded rate.

This makes comparisons easier.

CAGR Formula

The standard formula is:

CAGR =
(Ending Value ÷ Beginning Value)^(1 ÷ Number of Years)
- 1

Where:

• Ending Value = value at the end of the period
• Beginning Value = value at the start
• Number of Years = length of the measurement period

The result is expressed as a percentage.

CAGR Example

Suppose an investment grows from $10,000 to $16,105 over five years.

Beginning Value = $10,000
Ending Value = $16,105
Years = 5

CAGR is:

CAGR =
($16,105 ÷ $10,000)^(1 ÷ 5)
- 1

Which is approximately:

10%

That means the investment grew at the equivalent of 10% compounded annually over the five-year period.

CAGR in Fundamental Investing

CAGR is especially useful in fundamental analysis because investors frequently evaluate how quickly important business metrics have grown over time.

Common examples include:

• Revenue CAGR
• Earnings per share CAGR
• Free cash flow CAGR
• Book value CAGR
• Dividend CAGR
• Operating income CAGR

A company that compounds these metrics at attractive rates may increase intrinsic value over time.

However, growth quality matters.

High CAGR alone does not prove that a business is attractive.

Investors should also examine:

• Profitability
• Return on invested capital
• Capital intensity
• Leverage
• Share dilution
• Valuation

Revenue CAGR

Revenue CAGR measures the compounded annual growth rate of sales.

For example:

Revenue Year 1: $1 Billion
Revenue Year 5: $1.464 Billion

Over four years:

CAGR =
($1.464B ÷ $1.0B)^(1 ÷ 4)
- 1

≈ 10%

Revenue CAGR can help identify whether a company is expanding consistently over time.

But investors should also determine whether growth came from:

• Organic demand
• Acquisitions
• Price increases
• New products
• Market expansion

Earnings CAGR

Earnings CAGR measures the compounded annual growth rate of profits, commonly net income or earnings per share.

Suppose EPS grows from:

$2.00
to
$4.00
over 5 years

CAGR would be:

($4.00 ÷ $2.00)^(1 ÷ 5)
- 1

≈ 14.9%

That indicates earnings compounded at approximately 14.9% annually.

However, earnings growth should be examined for quality.

Accounting changes, buybacks, leverage, and unusual items can affect reported growth.

Free Cash Flow CAGR

Free cash flow CAGR can be particularly useful for fundamental investors because it tracks growth in cash generated after operating and capital-investment requirements.

A company with strong free cash flow CAGR may have greater capacity to:

• Reinvest
• Pay dividends
• Repurchase shares
• Reduce debt
• Make acquisitions

But the starting and ending values should be normalized when unusual years distort the comparison.

Dividend CAGR

Dividend CAGR measures the compounded annual growth rate of dividend payments.

Suppose an annual dividend grows from $1.00 to $1.61 over five years.

Dividend CAGR
≈ 10%

Dividend-growth investors often use this metric to compare the pace at which shareholder income has increased.

However, dividend CAGR should be considered alongside payout ratio and free cash flow.

Rapid dividend growth may be unsustainable if the company is distributing an increasing share of earnings.

CAGR vs. Annualized Return

CAGR and annualized return are often mathematically identical when evaluating a beginning value, ending value, and time period with no external cash flows.

Both use:

(Ending Value ÷ Beginning Value)^(1 ÷ Years) - 1

The difference is often contextual.

CAGR is frequently used for growth in:

• Revenue
• Earnings
• Dividends
• Business metrics

Annualized return is more commonly used for:

• Investment performance
• Portfolio returns
• Fund performance

In many situations, the underlying mathematics is the same.

CAGR vs. Average Growth Rate

CAGR should not be confused with a simple arithmetic average.

Suppose a company’s revenue changes by:

Year 1: +20%
Year 2: -10%
Year 3: +30%

The arithmetic average growth rate is:

(20% - 10% + 30%) ÷ 3
= 13.3%

But that does not necessarily equal the compounded growth rate.

CAGR uses the actual beginning and ending values, which makes it more appropriate for measuring multi-year compounding.

CAGR and Compounding

CAGR is fundamentally a compounding metric.

Suppose $100 grows at 8% annually.

Year 1: $108
Year 2: $116.64
Year 3: $125.97

Each year’s growth builds on the previous year’s larger base.

This compounding effect is why CAGR is different from simply dividing total growth by the number of years.

CAGR and Total Return

Total return measures the complete gain over the entire period.

CAGR converts that total gain into a compounded annual rate.

For example:

Beginning Value: $100
Ending Value: $150
Holding Period: 5 Years

Total return:

($150 - $100)
÷ $100

= 50%

CAGR:

($150 ÷ $100)^(1 ÷ 5)
- 1

≈ 8.45%

The investment gained 50% in total, equivalent to approximately 8.45% compounded annually.

CAGR and Volatility

One major limitation of CAGR is that it hides volatility.

Two investments can have the same CAGR while experiencing very different paths.

For example:

Investment A:
Steady Growth Each Year

Investment B:
Large Gains and Large Losses

Both can end at the same final value and therefore have the same CAGR.

CAGR does not tell investors which path was smoother or riskier.

CAGR and Maximum Drawdown

CAGR should often be evaluated alongside maximum drawdown.

Suppose two portfolios both have:

CAGR = 10%

But:

Portfolio A Maximum Drawdown = 15%

Portfolio B Maximum Drawdown = 50%

Their long-term growth rates are identical, but the risk experience was dramatically different.

CAGR measures growth.

Maximum drawdown provides downside context.

CAGR and the Sharpe Ratio

The Sharpe Ratio adds risk information that CAGR does not provide.

Conceptually:

CAGR
→ Measures Compounded Growth Rate

Sharpe Ratio
→ Measures Excess Return Relative to Volatility

A strategy can have a strong CAGR but a weak Sharpe Ratio if that return came with extreme volatility.

CAGR and Business Quality

For fundamental investors, a high CAGR is more valuable when the growth is economically attractive.

For example, revenue growth that requires massive amounts of new capital may be less valuable than similar growth generated with high returns on invested capital.

A useful framework is:

Growth Rate
+
Return on Capital
+
Cash Conversion
=
Higher-Quality Growth

Growth should create value rather than merely increase company size.

CAGR and Return on Invested Capital

CAGR and ROIC can be especially powerful when evaluated together.

A company may grow rapidly, but if its return on invested capital is poor, that growth can destroy shareholder value.

Conversely, a company that reinvests at high ROIC while growing steadily may compound intrinsic value at attractive rates.

Fundamental investors should therefore avoid analyzing CAGR in isolation.

CAGR and Share Dilution

Company-level growth does not always translate into shareholder growth.

Suppose net income grows at 10% CAGR, but the company also issues substantial new shares.

Earnings per share may grow much more slowly.

Investors should therefore distinguish between:

• Revenue CAGR
• Net income CAGR
• EPS CAGR
• Free cash flow per share CAGR

Per-share growth is often more relevant to existing shareholders.

CAGR and Acquisitions

Acquisitions can increase reported revenue and earnings CAGR.

But acquisition-driven growth may require:

• Debt
• Equity issuance
• Integration costs
• Premium purchase prices

Investors should determine whether CAGR reflects genuine organic growth or purchased growth.

High headline growth can be misleading when acquisitions destroy value.

CAGR and Inflation

Nominal CAGR does not account for inflation.

Suppose an investment grows at:

Nominal CAGR: 8%
Inflation: 3%

Approximate real CAGR is around:

5%

A more precise real-growth calculation accounts for compounding.

For long-term wealth building, real CAGR can be more informative than nominal CAGR.

CAGR and Time Period Selection

CAGR can vary substantially depending on the starting and ending years selected.

A business may appear to have very high growth if the starting year was temporarily depressed.

Similarly, using a peak year as the starting point may understate long-term growth.

Investors should consider:

• Business cycles
• Recessions
• Acquisitions
• One-time events
• Normalized earnings

Using multiple periods can provide better context.

3-Year vs. 5-Year vs. 10-Year CAGR

Different periods can reveal different trends.

For example:

3-Year Revenue CAGR: 18%
5-Year Revenue CAGR: 12%
10-Year Revenue CAGR: 7%

This may indicate that growth has accelerated recently.

The opposite pattern could suggest deceleration.

Comparing several time horizons can help investors understand whether growth is improving, stable, or slowing.

CAGR With Negative Values

CAGR becomes problematic when the beginning or ending value is negative.

For example, a company moving from a $100 million loss to a $50 million profit does not produce a meaningful standard CAGR.

In these situations, investors may need to use:

• Absolute changes
• Margin improvement
• Multi-year normalized figures
• Other growth measures

CAGR works best with positive beginning and ending values.

CAGR With External Cash Flows

The standard CAGR formula does not account properly for contributions or withdrawals made during an investment period.

For portfolios with external cash flows, investors may need:

• Time-weighted return
• Money-weighted return
• Internal rate of return

CAGR is most appropriate when measuring the growth of a single beginning value into a single ending value.

What Is a Good CAGR?

There is no universally good CAGR.

A strong growth rate depends on:

• Industry
• Company maturity
• Capital requirements
• Profitability
• Valuation
• Competitive position

A 20% CAGR may be impressive for a mature business but weak if it required unsustainable leverage or heavy dilution.

A lower CAGR can be more valuable when it is durable, highly profitable, and capital efficient.

Limitations of CAGR

CAGR has several important limitations.

It:

• Smooths year-to-year variation
• Hides volatility
• Does not show drawdowns
• Can be distorted by unusual starting or ending years
• Does not explain the source of growth
• Does not account for capital intensity
• Does not measure risk
• Becomes problematic with negative values
• Does not handle external cash flows well

CAGR should therefore be combined with broader fundamental and portfolio analysis.

Common CAGR Mistakes

Common mistakes include:

• Dividing total growth by the number of years
• Confusing CAGR with arithmetic average growth
• Ignoring volatility
• Ignoring maximum drawdown
• Using distorted starting or ending values
• Ignoring inflation
• Ignoring share dilution
• Ignoring acquisition-driven growth
• Ignoring capital intensity
• Treating historical CAGR as a forecast
• Using CAGR when values are negative
• Comparing periods of different lengths without context

CAGR is most useful when it measures durable, economically valuable compounding.
