Imagine this: You diligently save and invest your hard-earned money, confident that it will eventually grow over time. But here’s the thing – simply investing isn’t enough. To truly harness the potential of your money, you need to understand the remarkable force that lies within compound interest. In this blog, we will delve deep into how compound interest works and more importantly, how to calculate compound interest online.
What is compound interest?
When you put your money in a savings account or invest it, you earn something called “interest.” Interest is basically extra money that is added to your original amount. With compound interest, not only do you earn interest on your initial investment, but you also earn interest on the interest you’ve already earned.
Let’s say you have ₹10,000 in a savings account with a 5% annual interest rate. At the end of the first year, you would earn ₹500 in interest (5% of ₹10,000). Now the ₹10,500 becomes the new starting point for the next year.
So, in the second year, you earn interest not only on your initial ₹10,000 but also on the additional ₹500 you earned in interest. This means you would earn ₹525 in interest (5% of ₹10,500).
As time goes on, this cycle of earning interest on both your original amount and the accumulated interest continues, causing your money to grow faster. The longer you keep your money invested, the more substantial the effect of compound interest becomes.
But the question remains, how to calculate compound interest? Well, you can either calculate compound interest online or even do it manually. Before we understand how a compound investment calculator works, let’s know how it can benefit us.

When you calculate compound interest online, it becomes easy to estimate your future investment value in a matter of seconds.
Compound Interest Formula
Instead of using the compounding calculator, one can also manually calculate the compound interest using the given formula:
A = the future value of the investment, including interest
P = the principal amount (initial investment)
r = annual interest rate (as a decimal)
n = number of times interest is compounded per year
t = number of years the money is invested
This formula calculates the compound interest of your investments over time.
Let’s understand this with an example:
If the principal amount is ₹10,000, the annual interest rate is 8%, and the investment is made for 10 years, we can calculate the compound interest using the formula:
P = ₹10,000 (principal amount)
r = 8% (annual interest rate = 0.08)
n = 1 (assuming interest is compounded annually)
t = 10 (number of years)
Substituting these values into the formula:
A = ₹10,000(1 + 0.08/1)^(1*10)
Using a calculator or spreadsheet, we can evaluate this expression to find the future value:
A ≈ ₹21,589.48
Therefore, the future value of the investment after 10 years with a principal amount of ₹10,000 and an annual interest rate of 8% is approximately ₹21,589.48.
If you are serious about investing, a compound interest calculator is a valuable tool that can help you plan out your investments and reach your financial goals.
Here are some additional tips for making the most out of compound interest:
- Be pragmatic about your investment goals. Don’t expect to get rich quickly. Compounding works best over the long run.
- Start saving early. The earlier you start saving, the more time your money gets to compound.
- Invest regularly. The more often you invest, the more time your money has to grow through compound interest.
- Reinvest your earnings. When you earn interest on your investments, reinvest those earnings so that they can continue to grow.
By harnessing the power of compound interest, your money can grow significantly over time. It accumulates and multiplies, helping you reach your financial goals sooner. By following the aforementioned steps, you can either calculate compound interest online or do it manually. Remember, the key is to start early and allow your money to compound over a long period, as the longer your money remains invested, the more it can grow.
1. What is compound interest?
