Manish has realized the power of compounding. Since the days he started earning, he has diligently set aside a small corpus which he saves from his monthly salary and deposits in his bank account. Bank pays him interest every month. Manish is also a determined investor and refrains from withdrawing anything from this account because he now believes in power of compounding. Given investment corpus, fixed annual rate of interest and maturity period calculate the amount the Manish will end up saving at the end of his tenure.
