What is Compound Interest?
Compound interest refers to a situation where an investment grows at an exponential rate, as the interest earned is added to the original principal amount, creating a larger base for earning even more interest. This compounding process leads to faster and more substantial growth of investments, making it a favoured choice for long-term financial planning and wealth accumulation. To accurately determine the return on investment, it is essential to have access to a trustworthy compound interest calculator.
What is a Compound Interest Calculator?
A compound interest calculator is a tool used to calculate the interest earned on a principal amount over a specified period of time, taking into account the compounding effect of reinvesting the interest earned. This calculator takes inputs such as the initial investment, the interest rate, and the compounding frequency and provides an estimate of the total amount that will be accumulated after a given period of time. It is a simple and convenient way to understand the potential growth of an investment and make informed financial decisions.
What is the Compound Interest Formula?
The calculation of compound interest is done using the following formula:
A = P (1 + r/n) ^ nt
- A = Compound Interest
- p = Principal Amount
- r = Rate of interest
- n = Number of times interest compounds in a year
- t = Duration in years
How to Calculate Compound Interest?
You can use the compound interest formula to calculate the compound interest. Here is an example to understand the calculation of compound interest easily.
Assume you have invested ₹10,000 with an annual interest rate of 15% for 5 years, with yearly compounding frequency. The returns for the first year will be 10,000 x 15/100 = ₹1,500.
For the second year, the interest will be calculated for ₹10,000 + ₹1,500 = ₹11,500. The interest will be ₹1,725 and the investment will be ₹13,325.
For the third year, the interest amount will stand at ₹1,998.75 and so on. This way you need to calculate for the entire investment duration. Finally, the investment amount will be approximately ₹20,114 by the end of 5 years.
Let us take the same example and use the formula of the compound interest A = P (1 + r/n) ^ nt,
P = ₹10,000
r = 15% = 0.15
n = 1
t = 5
A = 10,000 (1+0.15)^5 = ~₹20,113.57
Obviously, it is difficult to calculate these amounts manually or even using the formula especially when you have longer tenures. It takes time and is prone to errors easily. That is why you need a compound interest calculator in India by Angel One to make the task easier.

Simple Interest vs Compound Interest
Simple Interest and Compound Interest are two distinct methods for calculating interest on loans or investments.
Simple interest is a straightforward method where the interest is calculated solely on the initial principal amount over a specified time period. The interest remains constant throughout the period, and it is not added to the principal for future calculations. This makes it relatively easy to calculate and understand. However, since the interest doesn't compound, the overall growth of the investment is typically slower compared to compound interest.
On the other hand, compound interest is more dynamic and powerful. Here, the interest is not only calculated on the initial principal but also on the accumulated interest from previous periods. As a result, the interest itself starts generating interest, creating a compounding effect that accelerates growth over time. Compound interest is used in various financial instruments, like savings accounts, fixed deposits, and investments. It's especially beneficial for long-term investments, as the earnings snowball over time.
In essence, while simple interest provides a straightforward calculation, compound interest offers the advantage of exponential growth, making it a preferred choice for investors aiming for substantial returns over extended periods.
Simple Interest Formula
The formula for the simple interest calculator is as follows:
Simple interest = P X T X R / 100
- P = Principal amount (initial investment or loan amount)
- R = Rate of interest per year
- T = Duration in years
Let us consider an example to calculate the simple interest.
For instance, you want to take a loan of ₹1,00,000 at an interest rate of 10% per annum for 4 years. The simple interest calculation will be as follows:
Simple interest = 1,00,000 * 10 * 4 / 100 = ₹40,000
The simple interest of your loan of ₹1,00,000 for 4 years at a 10% interest rate annually will be ₹40,000.
