This user-friendly tool helps you make sense of the numbers, ensuring you know exactly how much your money can grow over time.

What Is Simple Interest?

Simple interest is one of the most straightforward ways to calculate interest on a loan or investment. It is determined by a fixed percentage of the principal amount over a specified time period. The formula for calculating simple interest is:

$\text{Simple Interest (SI)}=\frac{\text{Principal}\times \text{Rate}\times \text{Time}}{100}$

Where:

• Principal is the initial amount of money invested or borrowed.
• Rate is the annual interest rate (expressed as a percentage).
• Time is the duration in years for which the money is borrowed or invested.

Example: If you invest ₹1,000 at an interest rate of 5% for 3 years, the simple interest would be calculated as follows:

$\text{SI}=\frac{1000\times 5\times 3}{100}$

= ₹150

This means that after 3 years, you would earn ₹150 in interest, bringing your total amount to ₹1,150.

What Is Compound Interest?

Compound interest takes your investment to the next level by calculating interest on both the principal and the accumulated interest from previous periods. This means you earn interest on your interest, allowing your investment to grow faster over time. 

The formula for calculating compound interest is:

$\text{Compound Interest (CI)}:<br>$

= (Principal×(1+(Rate/n))^(n×Time))−Principal

Where:

• Principal is the initial amount.
• Rate is the annual interest rate.
• n is the number of times interest is compounded per year.
• Time is the number of years the money is invested or borrowed.

Example: If you invest ₹1,000 at a 5% interest rate compounded annually for 3 years, the calculation would look like this:

$\text{CI}=1000\times {(1+\frac{5}{100})}^{1\times 3}-1000\mathrm{<br>}\mathrm{ }$

= ₹157.63

This means that after 3 years, you would earn approximately ₹157.63 in interest, resulting in a total amount of ₹1,157.63.
