Compounding is an important concept in finance because it shows the role of reinvestments in building a substantial corpus. Compound interest is the interest calculated on the principal and previously accumulated interest.

This can be understood best with the 'snowball effect'. When a small snowball rolls down a slope, it accumulates more snow and ultimately becomes a large snowball. Similarly, compound interest leads to an exponential growth of your investment by accruing interest upon principal plus interest.

While you can calculate compound interest using complex formulas, it’s better to use our compound interest calculator. Simply enter the respective values here to get the result.

#### How Is Compound Interest Calculated?

As stated above, compound interest is simply interest on accumulated interest. It is calculated by multiplying your initial investment by the annual interest rate plus one raised to the number of years of investment.

You can find out the compound interest by subtracting the principal amount of your investment from its maturity amount. The formula to calculate the amount on maturity is as follows:

A = P(1 + r/n)^nt

Here,

P = Principal amount

A = Maturity Amount

r= Rate of interest

n = Number of times interest gets compounded annually

t = Number of years till maturity

This formula will give the total amount received after maturity.

Now, you can use the following formula to find out compound interest:

Compound interest (CI) = maturity amount – principal amount

Suppose you have invested ₹60,000 in a bond at an annual interest rate of 10% for 5 years. Returns generated by the investment in the first year will be ₹6000. For the second year, the interest will get calculated on (60,000 + 6000), i.e. ₹66,000 and it will accrue an interest amount of ₹6,600. Thus the cycle will continue.

Manual calculations are lengthy and time-consuming. Our compound interest calculator makes the task much easier.

#### What Factors Influence Compound Interest Returns?

Check the factors influencing compound interest returns:

• Time: Investments need time to grow. So, with a longer investment tenure, the possibility of earning massive profits becomes higher.
• Rate of Interest: A high-interest rate will help you to create a large corpus. Even a small increase in the interest rate can result in substantial profits over time due to the effects of compounding.
• Frequency: If the interest is compounded more frequently, it will lead to more returns. For instance, if the compounding is on a quarterly basis, the interest will be much higher than for annual compounding.
• Starting Capital: While it is true that compounding adds interest upon interest, it is also true that the larger your initial investment, the higher will be the returns. In other words, if you invest a huge sum of money, you will benefit more from compounding.

But you can get the same effect by investing smaller sums regularly.

#### Benefits of Power of Compounding

Here are the benefits of compounding on your investments:

• Multiplies the Principal Amount: With the help of compounding, you can multiply the principal amount by a huge margin across the tenure.
• Improves Return Potential: It increases the return potential in the next cycle, thereby improving your chances to earn higher returns.
• Requires Less Time to Build a Corpus: Investment options offering the benefit of the power of compounding help you to grow your corpus in much less time when compared with investment options with simple interest.
• Specialised Knowledge Not Required: An important benefit is that you don't need specialised knowledge to get its benefit. You can execute the power of compounding to maximise returns from any investment in financial instruments.

#### How Long Should You Remain Invested to Earn Compounding Benefits?

It is not possible to state the exact time frame a person should remain invested in to maximise their returns. This is because people have different financial goals. Moreover, a person's ability to invest will not match that of another person. Thus, financial objectives and choice of investment should determine tenure.

Other than the above-mentioned factors, the longer one stays invested, the higher will be the returns. Experts recommend starting investments as soon as possible because it will give ample time to grow a substantial corpus.

An example will help to understand this better. Suppose, Amit invests ₹2,00,000 every year in an investment option which offers compound interest of 10% per annum. Let us see how much he will have at the end of 3 years.

This table will illustrate how the power of compounding increases the corpus across a timeframe:

Year Opening Balance Investment 10% Interest Rate (per annum) Closing Balance
1st Year Nil ₹2,00,000 ₹20,000 ₹2,20,000
2nd Year ₹2,20,000 ₹2,00,000 ₹42,000 ₹4,62,000
3rd Year ₹4,62,000 ₹2,00,000 ₹66,200 ₹7,28,200

As we can see, Amit makes a total investment of ₹6,00,000. At the end of the 3rd year, its value increases to ₹7,28,200. The total amount of interest that he has earned stands at ₹1,28,200. As we can see, the longer he stays invested, the larger his profits become.

#### Differences between Compound Interest and Simple Interest

The table below shows the basic differences between compound interest and simple interest:

Simple Interest Compound Interest
Simple interest is earned on the principal amount only. Compound interest is earned on the principal as well as previously accrued interest.
The total amount of interest earned is small. The growth of wealth is not so substantial. The total amount of interest earned is higher. Over time, the wealth accumulated can become substantial.
Investors earn lower returns on principal compared to compound interest. Due to the benefit of compounding, people earn higher returns over simple interest.
Principal does not change and remains the same during the entire tenure. Principal increases because interest gets compounded and added to the principal.
It is not dependent upon the frequency of accumulation of interest. Compound interest depends on the frequency of interest accumulation. When the frequency increases, the amount increases.

#### Tips to Make the Power of Compounding Work for You

Here are some useful tips to help you reap the benefits of the power of compounding on your investments:

• Begin Early
When you start your investment journey early, you have a longer timeframe to you’re your wealth. Long investment tenure helps to earn higher returns. It’s alright to start with a small amount. Starting at a young age is what matters the most.
• Consider Equity Investments
Equities and other market-related investment options offer the possibility to earn inflation-beating returns. With the benefit of compounding, you can increase your wealth considerably.
• Avoid Premature Withdrawals
Compound interests will yield maximum benefits when you don’t make premature withdrawals. But if you withdraw your money before it can compound, it disturbs the flow of wealth accumulation.
• Track Investment Performance
It is important to periodically check the performance of your investments with that of the underlying index. If the investment is consistently underperforming when compared to the underlying benchmark index, the power of compounding will not generate many benefits.
