Compound Annual Growth Rate (CAGR) Calculator
Use this calculator to find the annualized growth rate of an investment, business metric, or portfolio over a specific time period.
Tip: CAGR smooths out volatility and gives you one consistent annual return number.
What is CAGR?
CAGR stands for Compound Annual Growth Rate. It tells you the average annual rate at which something grows over time, assuming growth compounds year after year.
Investors use CAGR to evaluate portfolio performance, compare funds, and benchmark long-term results. Business owners use it to track revenue growth, customer growth, or profit trends over multiple years.
Why CAGR is useful
- It summarizes multi-year performance in one clean annual percentage.
- It makes apples-to-apples comparison easier between different investments.
- It reduces noise from year-to-year ups and downs.
- It helps with planning and forecasting by using annualized return assumptions.
How to use this CAGR rate calculator
- Enter the beginning value (starting amount).
- Enter the ending value (final amount).
- Enter the number of years between the two values.
- Click Calculate CAGR.
You will instantly see your CAGR percentage, total return, and a few extra insights like growth multiple.
Example calculation
Suppose you invested $10,000 and it grew to $18,000 over 5 years.
- Beginning Value = 10,000
- Ending Value = 18,000
- Years = 5
The CAGR is approximately 12.47% per year.
| Metric | Value |
|---|---|
| Beginning Value | $10,000 |
| Ending Value | $18,000 |
| Time Period | 5 years |
| Growth Multiple | 1.8x |
| Compound Annual Growth Rate | 12.47% |
CAGR vs average annual return
These are not always the same:
- Average annual return is a simple arithmetic mean of yearly returns.
- CAGR is the geometric mean and reflects compounding.
When returns are volatile, CAGR is usually the better measure of long-term growth because it captures the real compounding path from start to finish.
What CAGR does not tell you
CAGR is powerful, but it has limitations:
- It hides volatility (big drawdowns may be masked).
- It does not show sequence risk.
- It does not adjust for inflation unless you do it separately.
- It ignores contributions and withdrawals unless modeled explicitly.
When to use CAGR
Great use cases
- Comparing two mutual funds over the same date range.
- Measuring long-term stock or ETF performance.
- Estimating annualized growth in business revenue over several years.
- Planning financial goals with a realistic annual growth assumption.
Less ideal use cases
- Short time windows (under 1 year).
- Assets with significant interim cash flows not captured in start/end values.
- Highly irregular investment patterns.
FAQ: CAGR calculator
Can CAGR be negative?
Yes. If your ending value is lower than your beginning value, CAGR will be negative, indicating annualized decline.
Is CAGR the same as APY?
Not exactly. APY is typically used for deposit products and includes compounding over a year. CAGR is a broader annualized growth metric across multi-year periods.
Should I use nominal or inflation-adjusted values?
For purchasing power analysis, adjust values for inflation first. That gives you a real CAGR instead of nominal CAGR.
What is a “good” CAGR?
It depends on risk, asset class, and time horizon. A “good” CAGR in a conservative bond portfolio is very different from a growth-stock portfolio.
Bottom line
A CAGR rate calculator is one of the quickest ways to evaluate long-term performance. Enter your start value, end value, and years, and you get a clean annualized return number that is easy to interpret and compare. Use CAGR alongside risk and volatility metrics for smarter financial decisions.
