Investing is all about growing your money over time. But how do you measure the true annual return on an investment that has fluctuated year by year? The answer lies in CAGR—the Compound Annual Growth Rate.
Our CAGR Return Calculator allows you to determine how much an investment has grown each year, on average, over a specific time period. This is crucial for comparing investment opportunities, evaluating past performance, or making data-driven decisions for future growth.
CAGR Return Calculator
💡 What is CAGR?
CAGR (Compound Annual Growth Rate) represents the smoothed annual rate of return for an investment over a defined time period. Unlike arithmetic averages, CAGR takes compounding into account, which means it reflects the actual return if the investment had grown at a steady rate.
Why CAGR is Important:
- Measures true investment performance over time
- Helps compare volatile investments with varying returns
- Shows how fast an investment grows annually on average
- Useful for stocks, mutual funds, real estate, and business revenue
🛠️ How to Use the CAGR Return Calculator
To calculate the CAGR, you’ll need just three key inputs:
- Initial Value (Beginning Investment)
The value of the investment at the start of the period. - Final Value (Ending Investment)
The value of the investment at the end of the period. - Time Period (Years)
The total number of years the investment was held.
Once these values are entered, the calculator instantly shows the CAGR as a percentage.
📐 CAGR Formula (Plain Text)
The formula used by the calculator is:
CAGR = ((Final Value / Initial Value) ^ (1 / Number of Years)) – 1
To express CAGR as a percentage, multiply the result by 100.
📚 Example Calculation
Let’s say you invested $10,000 in a stock and after 5 years, it grew to $16,105.
Initial Value: 10,000
Final Value: 16,105
Years: 5
Using the CAGR formula:
CAGR = ((16,105 / 10,000) ^ (1 / 5)) – 1
CAGR = (1.6105 ^ 0.2) – 1
CAGR ≈ 0.10 or 10%
➡️ The average annual growth rate of your investment was 10%.

🧾 CAGR vs Other Metrics
| Metric | Description | Includes Compounding? |
|---|---|---|
| CAGR | Average compounded annual growth | ✅ Yes |
| Arithmetic Average | Simple average of yearly returns | ❌ No |
| IRR | Internal Rate of Return with cash flows | ✅ Yes (complex) |
| ROI | Total percentage return | ❌ No |
➡️ CAGR strikes a balance between simplicity and accuracy.
🔍 Limitations of CAGR
While CAGR is useful, it has a few limitations:
- Doesn’t show volatility – CAGR smooths out fluctuations and hides risk
- Ignores interim cash flows – Like dividends or contributions
- Only accurate for lump sum investments
For more complex investment scenarios, consider metrics like IRR or XIRR.
🔁 CAGR in Reverse: Finding Future Value
You can rearrange the formula to project future value if you know the CAGR and initial investment:
Future Value = Initial Value × (1 + CAGR)^Years
Example:
$5,000 growing at 8% CAGR over 10 years:
FV = 5000 × (1.08)^10 = $10,794
📋 20 Frequently Asked Questions (FAQs)
1. What is a CAGR calculator used for?
To calculate the average annual growth rate of an investment over a period.
2. Is CAGR the same as average annual return?
Not exactly. CAGR considers compounding, while average return is a simple mean.
3. Can CAGR be negative?
Yes. If the investment loses value, the CAGR will be negative.
4. What is a good CAGR for investment?
This depends on the asset. Stocks may aim for 7–10%, while savings accounts may be 1–3%.
5. Does CAGR consider risk?
No. It’s purely a performance metric and doesn’t account for volatility.
6. How is CAGR different from ROI?
ROI shows total return, while CAGR shows annualized growth with compounding.
7. Can I use CAGR for business growth?
Yes. It’s great for tracking revenue, profit, or customer base growth.
8. Does CAGR include dividends?
Only if dividends are reinvested and reflected in the final value.
9. Is CAGR affected by inflation?
Not directly. You need to adjust for inflation separately to get real CAGR.
10. Can CAGR be used for multiple cash flows?
No. Use IRR or XIRR for multiple cash flow scenarios.
11. What’s the difference between CAGR and IRR?
CAGR is simpler and for lump sums; IRR handles multiple cash flows and timing.
12. How many decimal places should I use for CAGR?
Usually 1–2 decimal places are sufficient for most use cases.
13. Does a higher CAGR mean a better investment?
Not always. It must be considered alongside volatility and risk.
14. What is the CAGR if the investment stays the same?
0%, because there is no growth.
15. Can I compare CAGR between two different time frames?
Yes, but keep in mind the shorter time frames may be skewed by short-term events.
16. Is CAGR the same as annual return?
No. Annual return can vary yearly; CAGR averages them into one steady rate.
17. What are typical CAGR values for the S&P 500?
Historically, 7–10% CAGR over long periods, depending on time frame.
18. How do I use CAGR to project growth?
Rearrange the formula: Final Value = Initial Value × (1 + CAGR)^Years
19. Can CAGR be used monthly?
Yes, but convert the time period to years (e.g., 6 months = 0.5 years).
20. Is the CAGR Return Calculator free to use?
Yes, it’s 100% free and works on all devices with internet access.
