1. What is Compound Annual Growth Rate (CAGR)?
Any investment that offers you the benefit of compounding can help you double your investment and build wealth. CAGR shows how much a person’s investment grew over a specific period of time. In other words, it is the average returns an investor has earned on the investments after a given interval say one year. The bank or the financial institution calculates this rate in terms of percentage.
A single stock or a mutual fund cannot provide you a constant rate of return every year. The rate may change from year to year. Furthermore, if you make repeated investments, you need to know the return earned on all the investments together. For instance, say you have invested in ELSS with a five-year tenure. CAGR tells you how much return a fund earned you every year during this period. However, this is applicable only if you re-invest your gains every year.
2. How to calculate Compound Annual Growth Rate?
Most of the investors rely on absolute returns to ascertain performance of their investments. But it does not consider time value of money. On the other hand, CAGR takes into the account the period for which you stayed invested in the given avenue. It gives you an approximate rate at which your investment would grow if there is no volatility involved.
In fact, it is a good way to smooth out the fluctuations experienced by the given asset over a specific time period. Then, you may easily interpret how did it perform over the particular horizon. It is one of the great means to gauge how a given investment fared as compared to its price.
You may calculate CAGR in 3 easy steps. You must know these three numbers.
a. The investment made in the initial year (the first year of investment)
b. Value of investment at the end of the year and
c. Tenure of investment.
You can calculate CAGR using our CAGR calculator as well. Apart from that let’s have a look at the following example to make the process clearer:
The formula for CAGR is:
For example, you bought a stock for ₹100 in 2015. It appreciated by 25% to ₹125 in the year 2016 and further appreciated to ₹150 in the year 2017. Therefore, the appreciation in the rate from 2015 to 2017 was 50%.
If you want to know the growth rate of your investments for the complete period of time, use CAGR. If we put the above values in the formula, Compound Annual Growth Rate for your investment between 2015 and 2017 will be 22.47%.
3. Compound Annual Growth Rate & Mutual Fund Returns
In case of an investment avenue like mutual funds, you need to ascertain whether it’s a worth investing or not. For that you require means to measure it’s performance over a given period. Mutual fund fact sheet would give growth rates across different time horizons for the fund. But then it might seem confusing to judge the fund performance based on multiple rates. Instead, if you could know how it has grown annually, then things may get simpler.
This is where CAGR will help by providing you a single annual growth rate. Apart from this, it also puts the concept of compound interest into picture. Most of the investment avenues including mutual funds use compound interest to compute returns. So, CAGR would be an apt way to measure fund performance.
4. What Investors should know about CAGR?
a. The CAGR is not an indicator of sales that happened from the starting year to the last year. In some cases, all the growth may be concentrated only in the initial year or in the end year.
b. Sometimes, two investments may reflect the same CAGR, with one being more lucrative than the other. This could be because the growth was faster in the initial year for one, while the growth happened in the last year for the other.
c. They usually employ CAGR for investment periods ranging from 3 to 7 years. If the tenure is more than, say, 10 years, then the CAGR may camouflage the sub-trends in between.
d. Remember, Compound Annual Growth Rate is different from year-on-year (eg: return on 21 March 2017 vs that on 21 March 2018) growth rate
5. What are the other ways to determine returns?
There are other types of returns, besides CAGR, that are useful in analyzing the performance of mutual funds.
a. Annualized returns
It is the geometric average amount of funds that an investment creates every year for a fixed period of time. Annualized returns signify the return rate an investor earns for a given period, considering the annual compounding of returns. This gives clarity on how the investment would perform without focusing on the market volatility of markets.
b. Trailing returns
This is useful for calculating the historical performance of your funds on daily, weekly, monthly or annual basis. Trailing returns method is perfect for one-time investment. If you invest an amount on 17th April 2017, the 1-month trailing return period will range from 17th April 2017 to 17th May 2017.
c. Return since launch
In a nutshell, in spite of other methods, CAGR is far more reliable to track the growth of an investment. This is mainly because the annual return rate doesn’t take the compounding factor into consideration, leading to overestimation. Thus it is useful to understand how a mutual fund grows in terms of CAGR and use it to compare different funds. If such in-depth research is not for you, then you can invest in our hand-picked mutual funds from the country’s top fund houses.
