Also, it gives a comparison between the total amount of money deposited and the total interest earned, in form of a pie chart. In addition, it provides the graphical representation of the future values over time, consisting of the original principal and the cumulative interest. Lastly, the Compound Interest Table shows the balance and the payment made in each period.

What is Compound Interest?

Money makes money, and the money that money makes, makes more money. Compound interest is the interest earned on the money saved plus the interest earned. It speeds us the growth of your savings or investments. Inversely, it increases the debt balances you owe over time. In short, with compound interest, your interest earns interest.

Let's understand this term with an example.

Example:
  • Let's say you have $10,000 in your savings account that earns 4% annual interest. In a year, you will earn $400 making a new balance of $10,400.
  • In the second year, you will earn 4% on the balance at the end of the first year, which is $10,400. So, you will earn $416 as interest and make a new balance of $10,816 at the end of the second year.

Moreover, you can make additional payments at the start or the end of the compounding year. Also, the interest is compounded at different intervals of time. Such as annually, monthly, daily, and even repeatedly.

Consider that the interest you earned compounded monthly rather than annually on your savings account. Then, at the end of ten years, your total balance will be $14,908. Also, you will earn an additional $106 from interest being compounded more repeatedly.

How to Calculate Compound Interest?

So, till now we have gained a lot of knowledge about the term "Compound Interest". Now let's learn how to calculate it manually.

However, our compound interest calculator provides you with the most effortless way to calculate the growth in your money over time with the compounding interest. But if you still wish to calculate it on your own, then follow the instructions below.

So, before getting started, let's know about the compound interest formula. Because it's key to getting all the required results.

Compound Interest Formula

Compound Interest Formula

Where,

A = Final amount (principal + interest earned)
P = Principal amount (present value)
r = Annual interest rate (in decimal)
n = Number of compounding periods per year
t = Total time (in years)

Now let's take an example to understand it more deeply.

Example:

Suppose you make an investment of $5000 at the rate of 5% annual interest compounded monthly. Find out what your investment will become after 10 years.

Solution:

Here,

P = $5000
r = 5/100 = 0.05 (in decimal)
n = 12 (compounded monthly)
t = 10

Now place all the values in the compound interest formula.

A =  P( 1 +  
r
n
 )nt
A =  5000( 1 +  
0.05
12
 )(12 × 10)

A = 5000 × (1.0041667)120

A = 5000 × 1.647016

So, A = 8235

Thus, your investment becomes $8,235 earning you a total interest of $3,235 in 10 years.

Magic of Compounding

Compounding is a mathematical process to grow the potential earnings from an investment or savings. It makes sure that the interest is earned on the original amount as well as on the returns. It is a continual process and benefits the most over the long term. Compounding can turn even small investments into large ones if you give enough time.

Here, we are discussing some of the tips for you to make maximum profit from the compounding process.

1. Begin early

Start making investments the moment you start earning. Remember that compounding works best when you start early and keep on investing for the long term.

Let's say you start investing now. You make an investment of $1000/month for 5 years at a 5% rate of annual interest for yearly compounding. Your friend made the same investment as you but started 2 years later than you. Then, your maturity amount will be $70,347 and your friend will get $40,564. A total loss of $29,783. So, it's better to begin early.

2. Discipline

Maintain discipline with respect to your investments if you wish to benefit from compounding. So, ensure that you invest regularly.

3. Show Patience

Patience is the key to profits in compounding. Do not let your personal biases or the changes in the market influence you.
