Now the question in your mind will be that ₹ 1 crore has been made, but how will ₹ 61,000 be received every month? When after 25 years you will have a corpus of more than Rs 1 crore, the interest earned on it alone will be around Rs 7.3 lakh annually. In this way, without touching your principal amount of Rs 1 crore, you will continue to get a handsome income of ₹ 60,000 to ₹ 61,000 every month in the form of interest.
