Using CAGR to Identify Long-Term Investment Opportunities

Chris Carreck, March 15, 2025January 31, 2025

Learn How to Use CAGR to Identify Long-Term Investment Opportunities in the Stock Market. When evaluating a company’s growth potential, investors need a reliable metric that smooths out short-term fluctuations and provides a clear picture of long-term performance. One of the most effective tools for this purpose is the Compound Annual Growth Rate (CAGR). Whether you’re analyzing revenue, earnings, or stock price growth, CAGR can help you make informed investment decisions.

In this article, we’ll break down what CAGR is, how to calculate it, why it matters, and how to use it effectively when assessing stocks for long-term investment.

What is CAGR?

CAGR (Compound Annual Growth Rate) represents the smoothed annualized growth rate of an investment or financial metric over a specified period. Unlike simple average growth rates, which can be skewed by short-term volatility, CAGR provides a more accurate representation of steady growth.

CAGR is commonly used to analyze:
✔ Revenue growth (how fast a company is increasing sales)
✔ Earnings per share (EPS) growth (how well profits are expanding)
✔ Stock price growth (how well an investment has performed over time)

For long-term investors, CAGR helps compare companies across different industries and timeframes, making it a valuable metric for stock selection.

How to Calculate CAGR

The CAGR formula is:

CAGR=(EVBV)1n−1CAGR = \left( \frac{EV}{BV} \right)^{\frac{1}{n}} – 1CAGR=(BVEV​)n1​−1

Where:

  • EV = Ending Value (e.g., revenue or stock price at the end of the period)
  • BV = Beginning Value (e.g., revenue or stock price at the start of the period)
  • n = Number of years

Example Calculation: Apple (AAPL) Revenue Growth

Let’s say Apple’s revenue in 2018 was $265.6 billion, and in 2023, it was $394.3 billion. We calculate the CAGR as follows:

CAGR=(394.3265.6)15−1CAGR = \left( \frac{394.3}{265.6} \right)^{\frac{1}{5}} – 1CAGR=(265.6394.3​)51​−1 CAGR=(1.485)0.2−1CAGR = (1.485)^{0.2} – 1CAGR=(1.485)0.2−1 CAGR≈8.2%CAGR \approx 8.2\%CAGR≈8.2%

This means Apple’s revenue grew at an average annual rate of 8.2% over the five-year period.

Why CAGR is Important for Investors

1. It Provides a Realistic Growth Picture

Unlike simple growth rates, which may be distorted by short-term market fluctuations, CAGR smooths out volatility, making it ideal for assessing long-term trends.

2. It Helps Compare Companies Accurately

CAGR allows investors to compare growth rates between different companies and industries. For example, if Amazon (AMZN) has a revenue CAGR of 20% while Walmart (WMT) has a CAGR of 5%, it indicates Amazon is expanding much faster than Walmart.

3. It Highlights Consistency

A steadily increasing CAGR suggests a strong, well-managed company with a sustainable growth strategy. Conversely, declining CAGR may signal slowing demand or competitive pressures.

What is a Good CAGR?

The ideal CAGR depends on the industry:

Industry Typical CAGR Range
Tech & Software (e.g., Microsoft – MSFT) 10-30%
E-Commerce (e.g., Amazon – AMZN) 15-40%
Consumer Goods (e.g., Coca-Cola – KO) 3-8%
Healthcare (e.g., Johnson & Johnson – JNJ) 5-12%
Utilities (e.g., Duke Energy – DUK) 2-6%

Higher CAGRs are more common in growth sectors like technology, while lower CAGRs are typical in mature industries such as utilities and consumer staples.

Comparing Companies Using CAGR

To illustrate how CAGR helps in stock selection, let’s compare two companies in the electric vehicle (EV) sector: Tesla (TSLA) and Ford (F).

Company Revenue in 2018 Revenue in 2023 CAGR (2018-2023)
Tesla (TSLA) $21.5B $96.8B 35.3%
Ford (F) $160.3B $174.2B 1.7%

Tesla’s high CAGR (35.3%) suggests rapid expansion, whereas Ford’s low CAGR (1.7%) indicates slower growth. Investors seeking high growth may prefer Tesla, while those valuing stability may favor Ford.

CAGR in Investment Decision-Making

While CAGR is a powerful metric, it should be used alongside other financial indicators:

  1. Profitability Metrics: High CAGR is meaningless if a company isn’t profitable. Check net income and profit margins.
  2. Debt Levels: A company growing via excessive debt may struggle in downturns.
  3. Competitive Moat: Does the company have a sustainable competitive advantage (e.g., Apple’s ecosystem or Google’s search dominance)?
  4. Valuation: A high CAGR stock may be overvalued, so compare the Price-to-Earnings (P/E) ratio with peers.

Limitations of CAGR

1. Assumes Constant Growth

CAGR assumes a steady growth rate, which rarely happens in real life due to economic downturns, market cycles, and industry disruptions.

2. Can Be Misleading for Volatile Stocks

For highly volatile stocks, CAGR might not reflect the actual investment experience. For example, Meta (META) had a strong CAGR before facing regulatory and competitive challenges.

3. Ignores External Factors

CAGR does not consider:

  • Inflation (which impacts real purchasing power)
  • Market cycles (recessions and booms)
  • Competitive threats (new entrants disrupting an industry)

How to Calculate CAGR Easily

Instead of manual calculations, you can use:
🔹 Online CAGR calculators (available on financial websites)
🔹 Spreadsheet formulas (Excel & Google Sheets: =((EV/BV)^(1/n))-1)
🔹 Stock research platforms (Yahoo Finance, Bloomberg, Morningstar)

Final Thoughts Why the Compound Annual Growth Rate is Valuable

CAGR is a valuable tool for assessing a company’s growth potential, helping investors identify strong, long-term investment opportunities. However, it should not be used in isolation. A company’s financial health, competitive advantages, and market conditions should also be considered before making an investment decision.

By incorporating CAGR into your analysis, you can make more informed, data-driven investment choices—whether you’re looking for high-growth tech stocks like Amazon (AMZN) or stable dividend payers like Johnson & Johnson (JNJ).

Happy Investing!
