The proper knowledge and prudent management of personal finances play an important role in wealth appreciation and financial analysis. Besides giving you a sense of independence, it also helps you plan your finances according to your financial goals. 

A key aspect in this regard is the rate of interest. Whether one is paying it on the availed credit or receiving it on the money invested, it is important for one to know not only how much is it but also how it is calculated and how it compounds.

The power of compounding is considered highly important for wealth appreciation. So, what is compound interest or what is the meaning of compound interest? What is the formula of compound interest? How does compound interest work? Let’s find out the answers to all these questions and many more!

What is compound interest Rate?

So, let’s begin by answering the most basic question in this regard – what is compound interest? or what is the compound interest definition?

Well, compound interest refers to a cumulative interest amount calculated on the principal deposit/loan amount and the interest earned/payable on it during its tenure. It is a very powerful formula in the sense that it calculates interest even on the accrued interest. This way, it makes the principal amount grow exponentially!

The effect of compounding depends on two factors namely the rate of interest and the frequency of compounding. The higher the interest rate and the higher the frequency, the larger would be the effect of compounding. Interest rates can compound at any frequency such as yearly, half-yearly, quarterly, monthly, weekly, bi-weekly, or even daily!

It is beneficial for investors to invest in financial securities or instruments that offer compound interest as this allows them to earn interest even on the interest earned by them in the preceding period.

However, for borrowers, it is not beneficial to pay compound interest. As this can lead them into a never-ending spiral of debt!

What should be the annual rate of compound interest?

Another interesting question that one must ask is what should be the annual rate of compound interest. Well, there is no correct answer to this question! The higher the interest rate the better it is when one is the investor. However, the lower the compound interest, the better it is when one borrows funds and needs to pay interest on them.

How to calculate compound interest?

After knowing what is compound interest, it’s time to understand what is the formula of compound interest. 

what is the formula for calculating compound interest?

Compound interest can be calculated using the below-mentioned formula – 

Compound Interest =  P(1+r/n)^nt – P

Where,

P = Principal amount

r = Rate of interest in percentage terms

n = Number of times the interest is compounded in a year

t = Tenure of deposit/loan

Let’s understand how compound interest works with the help of an example – 

Mr. A deposits Rs. 50,000, which bears a compound interest of 10% per annum and a tenure of 5 years. So, what is n in compound interest for Mr. A, it is 5.

Compound interest earned by Mr A after 5 years = 50,000 (1+0.1/1)^(5*1) – 50,000 

= Rs. 30,525.5 

However, if his deposit attracted a simple interest of 10% per annum for 5 years, then he would have just earned an interest of Rs. 25,000.

Simple interest earned by Mr. A after 5 years = Principal Amount * Interest Rate * Time Period =50,000*0.10*5 

= 25000
