How to Calculate CAGR in Excel: Complete Guide (2024)
Compound Annual Growth Rate (CAGR) is the most accurate way to calculate and compare the growth rates of investments over multiple time periods. Whether you’re analyzing stock performance, business revenue growth, or personal investment returns, CAGR provides a standardized metric that accounts for compounding effects.
Why CAGR Matters
- Eliminates volatility effects from year-to-year fluctuations
- Provides a single, comparable growth rate
- Essential for financial modeling and investment analysis
- Used by professionals in equity research, corporate finance, and portfolio management
CAGR Formula
The fundamental CAGR formula is:
CAGR = (EV/BV)(1/n) – 1
Where:
EV = Ending Value
BV = Beginning Value
n = Number of years
Step-by-Step: Calculating CAGR in Excel
- Organize Your Data
Create a simple table with three columns: Period, Beginning Value, and Ending Value. For example:
Period Beginning Value Ending Value 2019-2024 $10,000 $25,000 - Use the RRI Function (Recommended Method)
Excel’s RRI (Rate of Return for Irregular Intervals) function is perfect for CAGR calculations:
=RRI(nper, pv, fv)
Where:
nper = number of periods (years)
pv = present value (initial investment)
fv = future value (final amount)Example for 5-year growth from $10,000 to $25,000:
=RRI(5, 10000, 25000)
Result: 20.09% (formatted as percentage)
- Alternative Power Formula
For versions before Excel 2013 (which lack RRI), use this power formula:
=(25000/10000)^(1/5)-1
Format the cell as Percentage to see 20.09%
- XIRR for Irregular Cash Flows
When dealing with multiple contributions/withdrawals, use XIRR:
Date Amount 1/1/2019 -$10,000 1/1/2020 -$2,000 1/1/2024 $25,000 =XIRR(B2:B4, A2:A4)
Advanced CAGR Applications in Excel
Comparing Investments
Use CAGR to compare different investments regardless of their time horizons:
| Investment | Initial | Final | Years | CAGR |
|---|---|---|---|---|
| S&P 500 | $10,000 | $18,500 | 5 | 12.87% |
| Tech Stocks | $10,000 | $25,000 | 5 | 20.09% |
| Real Estate | $50,000 | $75,000 | 7 | 7.18% |
Projecting Future Values
Combine CAGR with Excel’s FV function to forecast growth:
=FV(rate, nper, pmt, [pv], [type])
Example: Project $10,000 growing at 15% CAGR for 10 years:
=FV(15%, 10, 0, -10000)
Result: $40,456.55
Common CAGR Mistakes to Avoid
- Ignoring Time Units
Always ensure your time period is in years. For months/days, convert to years (e.g., 18 months = 1.5 years)
- Negative Values
CAGR requires positive values. For negative returns, use XIRR instead
- Arithmetic Mean vs CAGR
Never average annual returns arithmetically. CAGR accounts for compounding effects that simple averages miss
- Formatting Errors
Always format CAGR results as percentages (Right-click → Format Cells → Percentage)
Real-World CAGR Examples
| Company | Period | Initial Value | Final Value | CAGR | Industry Benchmark |
|---|---|---|---|---|---|
| Apple (AAPL) | 2012-2022 | $54.52 | $149.18 | 19.2% | Tech: 15.8% |
| Tesla (TSLA) | 2017-2022 | $34.70 | $228.32 | 62.4% | Auto: 8.2% |
| Amazon (AMZN) | 2010-2020 | $125.57 | $3,256.93 | 58.7% | E-comm: 22.1% |
| S&P 500 Index | 1990-2020 | $100 | $1,020.43 | 10.7% | Market Avg: 10.5% |
Academic Research on CAGR
Financial economists have extensively studied CAGR’s applications in investment analysis. Key findings include:
- SEC’s guidance on CAGR usage in performance marketing (U.S. Securities and Exchange Commission)
- CFI’s comprehensive CAGR analysis (Corporate Finance Institute)
- NYU Stern’s historical CAGR data (New York University)

| A2 | Final Value | Input ending amount |
| A3 | Years | Input time period |
| A4 | =RRI(A3, A1, A2) | Calculates CAGR |
| A5 | =A2/A1-1 | Total growth rate |
| A6 | =A4*A3 | Total growth percentage |
CAGR vs Other Financial Metrics
| Metric | Formula | Best For | Limitations |
|---|---|---|---|
| CAGR | (EV/BV)^(1/n)-1 | Comparing investments over time | Ignores volatility, assumes smooth growth |
| XIRR | Excel XIRR function | Irregular cash flows | Sensitive to timing of cash flows |
| ROI | (Net Profit/Cost)*100 | Simple profitability | Ignores time value of money |
| Sharpe Ratio | (Return-RF)/StdDev | Risk-adjusted returns | Requires benchmark data |
Frequently Asked Questions
Can CAGR be negative?
Yes, if the final value is less than the initial value. This indicates a loss over the period.
How is CAGR different from annual return?
Annual return shows year-by-year performance, while CAGR smooths returns over the entire period.
What’s a good CAGR?
Depends on the asset class:
- Stocks: 7-10% (long-term average)
- Venture Capital: 20-30%
- Bonds: 3-5%
- Real Estate: 8-12%
Can I use CAGR for personal finance?
Absolutely. Use it to:
- Track retirement account growth
- Compare savings strategies
- Evaluate education fund performance
- Analyze salary growth over time
