What Compound Annual Growth Rate Tells Investors: CAGR Meaning, Formula and Calculation

Compound Annual Growth Rate (CAGR) is an important indicator of an investment’s performance over a given time. Therefore, when evaluating investments with compound returns, experts consider this metric vital for predicting future growth. 

In this blog, let us know more about CAGR meaning, how this component works in the real world and how to calculate CAGR. 

Quick Summary

• CAGR gives the average annual investment growth over a given time frame.
• Formula to calculate CAGR: (Final value/ starting value)^(1/number of years) -1
• Investors use CAGR to rebalance their portfolios and manage variable returns.
• For well-informed investments, CAGR is useful but consider other return metrics too.

What is CAGR?

The Compound Annual Growth Rate (full form of CAGR) depicts the average yearly growth rate of a particular investment for a time frame (normally more than 1 year). If you are analysing individual assets, you can largely rely on this metric. 

Additionally, it can help you rebalance investment portfolios and manage assets that give variable returns over time. For a better understanding, take a look at this example. 

Suppose, you put ₹5,000 in a particular mutual fund for over 7 years and experience an overall CAGR of 8%. It indicates that on average your investment grew by 8%. However, in reality, the growth rate varied every year. For instance, it can be a 10% growth in the first year, 5% growth in the second year and so on. 

Once you understand the CAGR definition and its concept, it will be much easier to evaluate investment returns and pick instruments that can effortlessly match your financial goals. 

How Does CAGR Work?

To understand how CAGR works, we can jump into a more detailed illustration. 

As discussed, CAGR takes into account compounding while evaluating the yearly average growth rate. 

To understand this better let us take an example.

Let's assume the initial investment amount is ₹1 lakh. Suppose, this figure became ₹1.55 lakh at the end of 11 years. 

To calculate the CAGR manually, you can implement the formula:

Compound Annual Growth Rate = (Ending Amount/ Initial Amount)^(1/Total Number of Years) - 1

After calculating, you will see the CAGR as 4.48%. 

It says that in the above scenario, the investment grew at an average rate of 4.48% every year over the entire tenure. 

How to Calculate Compound Annual Growth Rate?

You can follow the steps given here to find the CAGR of an investment online:

Step 1: Now, that you already know what a CAGR return means, you can easily determine the initial value of your investment and its ending value (after a desired time frame).

Step 2: Take into account the total number of years for the investment. 

Step 3: Use the CAGR formula: CAGR = (Final value/starting value)^(1/number of years) -1 or use an online calculator. 

Step 4: Multiply the CAGR value by 100 to express the outcome as a percentage. 

To prevent mistakes and ensure accuracy, it is recommended to use an online CAGR calculator.

Is There Any Other Way to Determine Returns? 

The average annual return for the Nifty 50 index over the last 15 years is about 10.75% CAGR. While it is great that the CAGR states the optimistic market segment, however, basing investment decisions solely on one metric is unwise.

Therefore, you need to understand more than just CAGR meaning to predict possible fluctuations and make smarter investment decisions.

Some alternative ways of determining returns include:

• Internal Rate of Return (IRR): IRR takes into account when and how much cash flows occur, giving a true picture of what an investor actually experiences throughout the tenure. For example, if you invest ₹50,000 today and another ₹50,000 a year later, the IRR will consider both of those investments and their timing.
• Return on Investment (ROI): When you talk about measuring the percentage gain or loss compared to the initial investment, you are actually looking at the return on investment (ROI). For example, if you put in ₹1 lakh and it grows to ₹1.2 lakh, you can calculate the ROI like this: (1.2 - 1) / 1 × 100 = 20%.
• Time-Weighted Returns: This approach eliminates the influence of cash flows, allowing one to concentrate purely on how well the investment is performing. It is particularly useful for comparing the performance of mutual funds or portfolio managers.

These strategies give investors a chance to look at returns from various perspectives. Whether the returns are absolute, annualised or risk-adjusted, these methods can help you make smarter investment choices.

What is Considered a Good CAGR Percentage?

When it comes to mutual funds, a solid CAGR usually falls between 8-12% for equity funds over the long haul, indicating a healthy and sustainable growth trajectory. In India, large-cap funds might aim for a CAGR of 12-15%, while small-cap funds can deliver higher returns, however with more volatility. 

What Investors Need to Know About CAGR? 

To apply CAGR meaning in mutual funds and other assets deriving compound growth, go through the pointers below:

• CAGR is Not an Indication of Overall Sales: Under no means, does CAGR reflect the sale taking place from the first year till the ending year. A specific period typically accounts for the bulk of sales. 
• Two Investments Can Reflect the Same CAGR: It can happen if the growth occurs faster initially for one investment while the second investment shows growth in the later stage. 
• CAGRs are Usually Calculated for Investment Periods up to 7 Years: CAGRs are calculated for prolonged periods like 7 years or 10 years and thus they may hide some sub-trends in between. 
• CAGR and YoY are Two Different Metrics: Year-over-year growth and compound annual growth rate are often mistakenly used synonymously, but they are in fact different.

Final Words 

Although other metrics consider market fluctuations, they tend to overlook the compounding factor, which often leads to overestimation. Therefore, if you understand the CAGR meaning and how to calculate it, you can compare different funds more accurately. This allows you to invest directly in funds from the best fund houses across India.
