Have you ever heard the phrase that your money is growing while you sleep? This is the power of compound interest. It is one of the very basic yet most effective methods for increasing your savings and investments throughout the years.
If you have ever thought about how to compute compounding, relax, it is simpler than it sounds. The following guide will clarify everything for you in a step-by-step manner so that you can employ it for your financial planning.
What Is Compound Interest?
Compound interest is the interest you get from both your original sum (the principal) and the interest that has accrued over time. In simpler terms, you earn interest on your interest, which is the reason for quicker money growth.
- Imagine you put ₹10,000 in a bank account that pays 10% per annum.
- During the first year, the interest you get is ₹1,000.
- The next year, the bank pays you not only for ₹10,000 but also for ₹1,000, resulting in even higher profits for you.
This is the very mechanism of compounding that makes your wealth increase at a rate higher than simple interest.
Formula for Compound Interest
Here’s the standard formula you’ll use when learning how to calculate compound interest – A=P(1+n/r)^nt
| Symbol | Meaning |
| A | Total amount after interest |
| P | Principal amount (initial money) |
| r | Annual interest rate (in decimal) |
| n | Number of times interest is compounded per year |
| t | Time period in years |
Once you find A, you can calculate your compound interest (CI) as CI=A−P
How Often Is Interest Compounded?
Interest can be compounded in different ways, depending on your bank or investment. Here’s how it changes your returns
| Compounding Frequency | Number of Times per Year | Example Use |
| Annually | 1 | Long-term savings |
| Semi-annually | 2 | Fixed deposits |
| Quarterly | 4 | Bank RDs, SIPs |
| Monthly | 12 | Credit cards, EMIs |
