If you invest, you would naturally want to know the returns they make over the years. We use something called compound annual growth rate or CAGR to calculate the rate of growth over time. The process involves complex calculations. So, it is always wise to take the help of an online CAGR calculator.

What is compounding?
While investing, it’s necessary to understand how compounding works. Although a CAGR calculator saves you the hassle, it is useful to know. Let’s say you have invested Rs 10,000 in a fixed deposit at an interest rate of 10 per cent for three years.
Calculate Compound Annual Growth Rate without using a CAGR calculator:
Initial capital = Rs 10,000
Capital at the end of year one = [10,000 + (10,000 x 10 per cent)] = 11,000
Capital at the end of year two = [11,000 + (11,000 x 10 per cent)] = 12,100
Capital at the end of year two = [12100 + (12,100 x 10 per cent)] = 13,310
The formula for calculating compound growth is as follows:
C = P x (1+r)n
C = Compounded value of the amount
P = Initial amount
R = Interest rate
N = Length or time of investment
In the above example, the compound growth rate would be 21 per cent.
What is CAGR?
Calculating CAGR is easy if returns are constant like those in the case of a fixed deposit. However, things become complicated when returns vary from one year to another. For example, when you invest in equity, you may earn returns of five per cent a year, 30 per cent the next year, and zero in another year. In such situations, the CAGR calculator comes in handy.
Why would you need a CAGR calculator?
If returns vary, you will want to know how your investments fared each year on an average. It is helpful as you can use this particular calculator to find out how returns on different types of investment options compare and use it to reshuffle portfolios. For instance, if the CAGR on your mid-cap mutual funds for three years is 20 per cent and that on large-cap funds is only 10 per cent, you may want to put more of your money in mid-cap funds and divest some of your large-cap funds.
There is a formula for calculating the compound annual growth rate. You don’t need to know it and can rely on a calculator. However, it is interesting to see how the entire thing works. When you doubt the results given by the CAGR calculator online, you can do the math yourself.
Here’s the formula:
CAGR(t0, tn) = [V(tn)/V(t0)]1/tn-to – 1
V(t0) = Original value
V(tn) = End value
tn-t0 = Number of years
Let’s say you have invested Rs 10,000 in stocks whose value has become Rs 25,000 at the end of five years. So, what’s the CAGR?
CAGR = (25000/10000)1/5 – 1 = 0.2, or 20 per cent.That looks difficult! It’s, therefore, better to stick to a compound growth calculator!
Here’s a word of warning before you fall back upon CAGR calculators. It’s just an average of annual growth rates over time. In a volatile situation, it may not give you an accurate picture of the worth of your investment. If you make 0 per cent returns in one year and 50 per cent in the next, the average will be 25 per cent! An online CAGR calculator is a tool among many to help you make sound investments. Don’t rely on them entirely!
While using a CAGR return calculator, you have to enter the following details; the value of the investment at the start, the end value, and the number of years.
At times, people get concerned over a good CAGR. Are you worried too? Generally, there is no hard and fast rule for a good compound annual growth rate. However, if you have invested either in stocks or mutual funds, and the online CAGR calculator shows anything between 18 to 25 per cent, you are doing well.
Frequently Asked Questions
How do you convert CAGR to annual growth?
CAGR depicts average growth rate over the years on an investment or loan when it is compounding. It smooths out fluctuations and let you get an idea of how your money will perform during the tenure. It is a ratio of the final value and the beginning value of the investment, calculated over a period.
Average Annual Growth Rate is a linear averaging formula and doesn’t take into account the effects of compounding.
What is a good CAGR percentage?
The value of a good CAGR percentage will vary with the kind of investment you have made. For equities, if your portfolio is growing at a CAGR of 18-25 percent, you are doing well. Similarly, for other types of investments, you can calculate different CAGR. However, remember, that CAGR is only average growth percentage, the actual growth value of your investment can be more or less than CAGR.
To avoid the trouble of complex calculation, use an online compound interest calculator.
Why is CAGR important?
Compounded annual growth rate (CAGR) represents the average rate at which an investment grows year on year. If an asset is said to have grown at 10 percent CAGR, it means the average appreciation was 10 percent. CAGR smooths out interim volatility and presents a steady rate of growth.
What does 5-year CAGR mean?
CAGR is a good measure to compare the performance of different investments over time. Suppose you want to invest in company XYZ, calculating 5-year CAGR of sales will help you decide if the company will grow with time.
To calculate 5-year CAGR, you can take help of a CAGR return calculator.
Can you use CAGR for months?
Yes, you can. Like CAGR, which computes average annual growth rate, CMGR calculates average monthly growth.
The formula of calculating CMGR is the same; you need to replace the number of years with months, that is 12.
CMGR= (end value/beginning value)^(1/n) – 1
Here n = investment period, while calculated monthly growth n represents the number of months in the year.
You can use an online CAGR calculator to calculate the growth rate, but calculators often give you annual value. Select a calculate that allows you to adjust the duration to months.
What is a promising CAGR for a company?
CAGR isn’t a fixed value. It varies by industry, company size, and more. However, as a rule of thumb, 5-10 percent annual growth in sales is considered decent for large-cap companies. For small and medium-cap companies, 10 percent growth rate is achievable.
If you want to calculate company growth before investing, use a CAGR return calculator that is available online.
Why is CAGR better than average?
Whether you should calculate CAGR or AAGR (annual average growth rate) depends on your purpose. However, in most cases, calculating CAGR is more viable. AAGR is a linear measure which doesn’t take into account the effects of compounding, can be misleading at times. But CAGR smooths out the impact of market volatility on periodic return.
What is market CAGR?
CAGR is a method to calculate how much a sector or a company will grow over a time period. The market CAGR refers to an estimated rate of growth of a sector. Suppose analysts said that the retail market would grow by 8 percent, it means that in the coming each year the industry will grow at an average rate of 8 percent from the previous year.
