Albert Einstein once said: Compound interest is the 8th wonder of the world. Those who can use it will receive riches, and those who do not understand... will have to pay for it. So compound interest What is ? How does the power of compound interest in saving and investing make billion-dollar tycoons appreciate it?

General information about compound interest

What is compound interest?

Compound interest (also known as compound interest ) is simply understood as after taking interest back, accumulating capital, continuing to put all that money back into savings/investment to get interest of higher value in next cycle. Compound interest has two factors: time and interest.

Formula to calculate compound interest

Compound interest is calculated according to the following formula:

A = P*(1+r/n)^n*t


In there:

  • A = future value
  • P = principal amount (initial investment amount)
  • r = nominal annual interest rate
  • n = number of times interest is principally entered per year
  • t = number of years borrowed money

Looking at the above formula, we can see, the power of compound interest is made up of the following 4 factors:

  • Interest rate: This is the factor that makes the greatest strength of compound interest . The higher the interest rate will help you get back the higher amount of interest that the essence of compound interest is to reinvest the interest. The higher the interest received when added to the original principal amount, the higher the profit will be in the following periods.
  • Initial amount (principal amount): This is an important factor in the early stages of compound interest generation. Compound interest arises when interest is added to the original principal to calculate interest for the next period, the higher your principal amount, the more interest will be.
  • Time: The sooner you start and the longer you last, the more compound interest will If you start early, compound interest will help you generate profits while you sleep.
  • Frequency: Compounding depends on how often interest is compounded, which can be annually, semi-annually, quarterly, monthly or daily. The more regular the frequency, the more times the principal is entered will increase steadily. The amount of profit that compound interest brings in the future is huge.

The power of compound interest in investing - saving

In investing in general or saving in banks in particular, compound interest has great power that, if you know how to take advantage, it can bring the highest benefits and create a great fortune for you in the future.

As for compound interest , in the first few years you will not be able to see its power clearly. The longer time after that (maybe 10, 20 years) you will see the compound interest generate for yourself a huge profit. To help you understand this power, CashBerry will illustrate with the following specific compound interest example :

You have 100 million dong and choose to deposit in a bank with compound interest for 10 years with an interest rate at the time of deposit of 7%/year, monthly principal interest. How much money will you get back after 10 years?

Applying the compound interest formula, we have:

  • P = 100,000,000
  • r = 7%
  • n = 12
  • t = 10

From there you can easily calculate: Compound interest = 100,000,000 * (1+7%/12)^(12*10) = 200,966,137 VND.

Thus, with only the initial 100 million, after 10 years of saving compound interest, you will receive: 200,966,137 VND. In which, the interest received is VND 100,966,137 (Total compound interest minus principal: 200,966,137 - 100,000,000).

The following table will clearly show you the difference when you deposit simple interest and compound interest, so you will see the magical power of taking advantage of compound interest in investing - saving.

Simple interest



70,000,000 VND

100,966,137 VND

 Looking at the table above, it can be seen that, with the same amount and time of savings, if you take advantage of the power of compound interest, you will have more interest than simple interest savings up to VND 30,966,137 .

In fact, not only in savings but also in financial investment in general ( stocks , real estate...), compound interest also "makes money" and helps you earn an unexpected number.

Considering the same investment, compared to simple interest, compound interest has much more magical power when it comes to giving you high returns. For example, you spend 1 billion VND to invest with 15% interest per year:

  • If calculated on simple interest: After 10 years, you will receive: VND 2,500,000,000 (specifically 1,000,000,000 * (1 + 15%*10)).
  • If calculated according to compound interest: After 10 years, you will receive a higher amount: VND 4,045,557,735 (specifically 1,000,000,000 * (1 + 15%)^10). This amount is more than simple interest to 1,545,557,735 VND.

As you can see, compound interest has the power and "power" to give you a higher value of profits in the future. Thanks to that, you can easily implement your long-term plans such as buying a house , buying a car , starting a business , ... or other goals in life. It is because of that power that compound interest is considered by many to be the 8th wonder of the world.

How to save money to enjoy compound interest

Principle of application of compound interest

When you want to invest to receive compound interest, you need to remember the following rules:

+ Principle 1: Save regularly and maintain monthly savings.

+ Principle 2: Do not withdraw money when it is not too necessary or not yet due for payment.

+ Principle 3: If reinvesting, the new investment amount should not exceed 20% of the total amount you own.
