What Is CAGR and How to Use It to Evaluate Stocks
A complete Bullrun guide to CAGR for Indian investors, explaining CAGR formula, revenue CAGR, profit CAGR, EPS CAGR, mistakes, sector interpretation and how to use CAGR without getting misled.
What Is CAGR?
CAGR stands for Compound Annual Growth Rate. It shows the annualized rate at which a number grows over a period of time, assuming it grew at a steady compounded rate. In stock analysis, investors use CAGR to understand revenue growth, profit growth, EPS growth, book value growth and share price returns.
CAGR = (Ending Value / Beginning Value) ^ (1 / Number of Years) minus 1
If a company’s revenue grows from ₹1,000 crore to ₹2,000 crore in five years, it did not necessarily grow at the same rate every year. CAGR converts that total growth into one clean annual growth number. It helps investors compare companies with different starting points and different growth periods.
Why CAGR Is Useful in Stock Analysis
Indian investors often get distracted by one-year growth. One good year can come from low base effect, commodity cycle recovery, price hikes, acquisition or one-time demand. CAGR forces you to look at a longer period. It smooths the noise and reveals the underlying compounding rate.
A company growing revenue at 18% CAGR for ten years is usually more interesting than a company growing 60% in one year after four weak years. Consistency matters because valuation depends on future durability, not past excitement.
CAGR is a powerful tool, but it can mislead when the starting year or ending year is unusual. Always inspect the yearly numbers behind the CAGR.
Simple CAGR Example
Assume a company’s revenue was ₹500 crore five years ago and is ₹1,250 crore today. The total growth is 150%, but the CAGR is around 20%. That means the company compounded revenue at roughly 20% annually over five years.
| Year | Revenue | Observation |
|---|---|---|
| Year 1 | ₹500 Cr | Starting base |
| Year 2 | ₹590 Cr | Growth year |
| Year 3 | ₹720 Cr | Momentum improves |
| Year 4 | ₹860 Cr | Scale builds |
| Year 5 | ₹1,020 Cr | Operating expansion |
| Year 6 | ₹1,250 Cr | Ending value |
The CAGR is cleaner than simply saying revenue more than doubled. It allows comparison with other companies, sector growth and valuation expectations.
Different Types of CAGR Investors Should Track
One CAGR number is not enough. A company can grow sales but not profit. It can grow profit but dilute equity. It can grow EPS but generate poor cash flow. Serious investors track multiple CAGR numbers together.
| CAGR Type | What It Shows | Investor Reading |
|---|---|---|
| Revenue CAGR | Growth in business scale | Shows demand and market expansion |
| EBITDA CAGR | Growth in operating earnings | Shows operating leverage and margin discipline |
| PAT CAGR | Growth in final profit | Shows shareholder earnings before dilution check |
| EPS CAGR | Growth in profit per share | Shows real growth for each shareholder |
| Book Value CAGR | Growth in net worth | Useful for banks, NBFCs and capital-heavy companies |
| Free Cash Flow CAGR | Growth in surplus cash | Best quality check for mature businesses |
Revenue CAGR vs Profit CAGR
Revenue CAGR tells you whether the business is growing. Profit CAGR tells you whether that growth is economically useful. If revenue CAGR is 20% but profit CAGR is 5%, margins are shrinking or costs are rising. If revenue CAGR is 12% but profit CAGR is 25%, operating leverage may be improving.
The best companies usually show revenue growth, margin stability, profit growth and cash flow growth together. When one number grows and the others do not, investors must investigate the reason.
What Is a Good CAGR for Indian Stocks?
A good CAGR depends on company size, sector and valuation. Large companies growing revenue at 10% to 12% with high ROCE can still create wealth. Midcaps growing earnings at 15% to 25% can be attractive if valuation is reasonable. Smallcaps can grow faster, but the quality and durability of growth must be tested harder.
| Company Type | Good Revenue CAGR | Good EPS CAGR | Investor Interpretation |
|---|---|---|---|
| Large cap compounder | 8% to 12% | 10% to 15% | Quality and durability matter |
| Mid cap growth company | 12% to 20% | 15% to 25% | Attractive if cash flow supports growth |
| Small cap emerging business | 18% plus | 20% plus | High potential but higher execution risk |
| Cyclical company | Varies | Use through-cycle CAGR | Do not use peak-year CAGR |
| Turnaround company | Can look very high | Check low base effect | Do not overpay for recovery |
CAGR Mistakes Investors Make
- Using one-year growth and calling it compounding.
- Choosing a depressed starting year to make CAGR look impressive.
- Using a peak ending year in cyclical companies.
- Ignoring share dilution while studying profit CAGR.
- Trusting revenue CAGR without checking margins and cash flow.
- Comparing CAGR across unrelated sectors.
- Paying any valuation just because historical CAGR is high.
How to Use CAGR with Valuation
CAGR should never be used alone. A company growing EPS at 18% CAGR may be attractive at 25 P/E but risky at 90 P/E. Growth has value only when the price paid leaves room for disappointment. The higher the valuation, the more perfect the future must be.
A practical framework is to compare EPS CAGR with P/E, ROCE and cash flow. If a company has 18% EPS CAGR, ROCE above 20%, low debt and strong operating cash flow, it deserves attention. If the same EPS CAGR comes with weak cash conversion and high debt, it deserves caution.
Common Investor Questions
What is CAGR in stocks?
CAGR in stocks means the annualized growth rate of a financial number or stock price over a period of time. Investors use it to study revenue, profit, EPS, book value and returns.
Is higher CAGR always better?
No. Higher CAGR is useful only if it is sustainable, cash-backed and not caused by a low base or one-time event. Quality of growth matters more than the number alone.
Which CAGR is most important for investors?
EPS CAGR and free cash flow CAGR are usually more important than revenue CAGR because they show what shareholders actually receive and whether profit converts into cash.
CAGR Shows Speed, Not Quality
CAGR helps investors measure growth, but it does not judge the quality of that growth. Always combine CAGR with margins, ROCE, debt, cash flow and valuation. The best stocks are not just fast growers. They are durable compounders bought at sensible prices.
