## What is Compound Interest?

Compound interest is like your money having a multiplier.  When you save, it's not just about earning interest on the original amount; it's like a magic booster that lets you earn interest on the interest you've already made.

Imagine you have some money saved, and instead of just earning interest on the initial amount, you also earn interest on the interest you've already made. It's like a snowball effect that can make your savings grow more quickly.

On the other hand, if you have a loan with compound interest, it means you're not only paying interest on what you borrowed but also on the interest that's already added up, making the total repayment higher over time. So, compound interest can either work in your favor, helping your savings grow faster, or make loans a bit more expensive in the long run.

### ‍What is a compound interest calculator?

A compound interest calculator is a tool that helps you figure out how your money grows or how loan repayments accumulate over time. You input values like the initial amount, interest rate, compounding frequency, and time, and it calculates the future value for you.

### How to Calculate Compound Interest?

To calculate compound interest, you can use the formula:

A = P (1 + r/n) ^ nt

Where:

P= Principal Amount

A= Compound interest

r= Rate of interest

n= Number of times interest compounds in a year

t=Number of years

Suppose you invest ₹50,000 at an annual interest rate of 10%, compounded annually, over a period of 5 years.

A = P (1 + r/n) ^ nt

• A is the future value of the investment (in this case, after 5 years),
• P is the principal amount (₹50,000),
• r is the annual interest rate (10% or 0.10 )
• n is the number of times interest is compounded per year (annually, so n=1),
• t is the time the money is invested for in years (5 years)

For

Year 1:  50,000× 1.10 =55,000

Year 2:     55,000× 1.10 =60,500

Year 3:  60,500× 1.10 =66,550

Year 4: 66,550× 1.10 =73,205

Year 5: 73,205× 1.10 =80,525

For the 5 year, the amount will stand at Rs 80,525
