What is compound interest?

Compound interest refers to a form of interest accrued on investments being added back onto their principal, creating snowball effect and exponentially growing interest earnings over time. The longer an investment period, the greater its growth potential.

Reinvesting this interest brings your new principal amount up to Rs.10,500. By year two, you would earn Rs.525 more from investing this same principal, making your new total Rs. 11,025. Over time, this process continues leading to exponential growth for your investment portfolio.
