Today, I am going to cover a very basic, fundamental and important concept. We have heard this word multiple times - Compounding. People talk about the Power of Compounding and its enormous potential. 



But what exactly is Compounding? How does Compounding work? Is Compounding really advantageous? If yes, how does it make THE DIFFERENCE?



Back in the old, golden school days, we were introduced to the concept of Interest in Mathematics. Interest is a predefined percentage of our Principal which is given back to us along with Principal when we keep our money in a Financial Instrument for a specified amount of time.

When we park our money in a Bank, we will get some interest for our Principal amount. Let us try to understand Simple Interest first.

Note:
Keep a notebook & pen ready to follow the calculations.
A calculator will also be handy.

Let's say that, on the first of every month, we deposit Rs 1000 in a Savings Bank account. We continue to deposit this monthly amount for a period of 120 months (10 years). Let us consider that the Bank provides us 8% Annual simple interest for the amount. So, now, let us see what happens to our money.

Now, since Annual Simple Interest Rate is 8%, the Monthly Simple Interest Rate would be:

8% divided by 12 months = 8/(100x12) = 8/1200

For Month 1:
Amount deposited - Rs 1000
Interest earned for that month - 1000 x 8/1200 = Rs 6.66

For Month 2:
Amount already present - Rs 1000
Amount deposited - Rs 1000
Interest earned for that month - 2000 x 8/1200 = Rs 13.33

For Month 3:
Amount already present - Rs 2000
Amount deposited - Rs 1000
Interest earned for that month - 3000 x 8/1200 = Rs 20

.
.
.

For Month 120:
Amount already present - Rs 119000
Amount deposited - Rs 1000
Interest earned for that month - 120000 x 8/1200 = Rs 800

At the end of 120 months, when we withdraw the amount, we will get our Principal (120 months x 1000) plus the Total Interest (Sum of Interests for each month -> 48400) = 
Rs 168400

As you can see, in this case, the Total Interest is added to the Final Principal amount.

Compounding:
Compounding is the process of getting Interest on Interest. In Compounding, your Interest gets added to the Principal (either Monthly, Quarterly, Half Yearly or Yearly) and the next Interest is calculated based on the Principal + Accumulated Interest. Confused?? Let's take the same example as an approach.

Monthly Compounding - Interest computed Monthly and added to Principal

Let's say that, on the first of every month, we deposit Rs 1000 in a Compounding account (Recurring Deposit). We continue to deposit this monthly amount for a period of 120 months (10 years). Let us consider that the Bank provides us 8% Annual Interest for the amount. Let us assume that Interest is Compounded Monthly.

So, now, let us see what happens to our money.

Now, since Annual Compounding Interest Rate is 8%, the Monthly Compounding Interest Rate would be:

8% divided by 12 months = 8/(100x12) = 8/1200

For Month 1:
Amount deposited - Rs 1000
Interest earned for that month - 1000 x 8/1200 = Rs 6.66

For Month 2:
Amount already present - Rs 1000 + Rs 6.66 = Rs 1006.66
Amount deposited - Rs 1000
Interest earned for that month - 2006.66 x 8/1200 = Rs 13.37

For Month 3:
Amount already present - Rs 2006.66 + Rs 13.37 = Rs 2020.044
Amount deposited - Rs 1000
Interest earned for that month - 3020.044 x 8/1200 = Rs 20.13

.
.
.

For Month 120:
Amount already present - Rs 181946
Amount deposited - Rs 1000
Interest earned for that month - 182946 x 8/1200 = Rs 1219.64

At the end of 120 months, when we withdraw the amount, we will get our Compounded Amount = Rs 184165.7 

We can see a clear difference here of Rs 184165 - 168400 = Rs 15765


Quarterly Compounding - Interest computed Quarterly and added to Principal

In this case, as the name suggests, Interest is added to the Principal Quarterly instead of Monthly (in the previous case) 

For Month 1:
Amount deposited - Rs 1000
Interest earned for that month - 1000 x 8/1200 = Rs 6.66

For Month 2:
Amount already present - Rs 1000
Amount deposited - Rs 1000
Interest earned for that month - 2000 x 8/1200 = Rs 13.33

For Month 3:
Amount already present - Rs 2000
Amount deposited - Rs 1000
Interest earned for that month - 3000 x 8/1200 = Rs 20

Interest earned for the quarter = Rs 6.66 + Rs 13.33 + Rs 20 = Rs 40

For Month 4:
Amount already present - Rs 3000 + Rs 40 (Quarterly Interest) = Rs 3040
Amount deposited - Rs 1000
Interest earned for that month - 4040 x 8/1200 = Rs 26.93

For Month 5:
Amount already present - Rs 4040
Amount deposited - Rs 1000
Interest earned for that month - 5040 x 8/1200 = Rs 33.6

For Month 6:
Amount already present - Rs 5040
Amount deposited - Rs 1000
Interest earned for that month - 6040 x 8/1200 = Rs 40.26

Interest earned for the quarter = Rs 26.93 + Rs 33.6 + Rs 40.26 = Rs 100.8

At the end of 120 months, when we withdraw the amount, we will get our Compounded Amount = Rs 183622

As you can clearly see, the Amount we get by Monthly Compounding is greater than the Amount we receive after Quarterly Compounding. But Compounding fetches far greater returns than just Simple Interest.

Half Yearly Compounding - Interest computed Half Yearly and added to Principal

In this case, as the name clearly suggests, Interests are added every 6 months and added to the Principal.

Yearly Compounding - Interest computed Half Yearly and added to Principal

In this case, as the name clearly suggests, Interests are added every 12 months and added to the Principal.

As the periodicity of compounding decreases (Monthly -> Yearly), the returns also decrease appropriately.

As you can clearly see, Compound Interest works for you if the following discipline is followed:

1) Systematic investment - A certain amount needs to be invested periodically, preferably every month in a Compounding plan (Recurring Deposit, Mutual Funds or Equity) without fail. Of course, RD (Recurring Deposit) is the safest since the Principal is guaranteed. But, the Rate of Compound Interest provided by Banks for RD will be very less. Hence, people try to invest in Mutual Funds or Equity in solid companies which can provide a better Compounding Interest over long term. If the bright company manages to grow at a rate of above 15% every year, the money gets compounded at the same pace.

2) Start early - Saving is a habit which needs to be cultivated at an early stage of life. A person who invests Rs 1000 in a RD with 8% Compound Interest for a period of 30 years will get Rs 1484262 on Maturity. The earlier you start the better.

3) Stay invested for a longer period of time - Compounding works only as the Principal + Accumulated Interest grows. The longer you are in the plan, the Interest starts working for you. The real power of Compounding can be seen when we continue this discipline for decades. You can retire rich.

So, with discipline, homework and long term vision, enormous wealth can be created with the amazing power of compounding. Its no wonder that the investors who created enormous wealth, are those, who stayed invested for a long long time.

Tap the Power of Compounding.. Don't underestimate its Wealth Creating Ability.

Note:
- We have tried to explain this concept in a simple layman term. Try to understand the fundamentals and then explore on your own.
- Ideally, when we calculate the monthly interest, I have taken 12 months for easy understanding. The more accurate method would be to calculate based on the number of days in the month. But, for understanding, this is good enough
- If there are any doubts or suggestions, please feel free to leave a comment below so that we can add/correct our thoughts. After all, we are all learning.

Basically if you are looking for 8% annual interest, it will be 8/100 divided by 12 and hence 8/1200.. We are dividing by 12 to get the monthly interest since we have 12 months in a year. I have explained in the article itself. Request you to have a closer look my friend.. Let me know in case you need any more clarifications..
