Investing double the amount (Rs. 20,000 SIP) for 25 years might result in approximately Rs. 10 crore, though the example focuses on the benefits of early investing for shorter durations.
"If you have completed a year, no matter how small the amount is, start investing early. Do n't make the mistake of thinking you have only one life and will invest later. Invest, live life and balance both. Mistake number four is over diversification. ... much less than 6.5 crores, in fact, I will tell you the best thing, for example, invest 00 and you do this from 25 to 35, only for 10 years, and after 10 years, when you will be 35, you will have 23 lakh rupees, now you do not touch this 2 lakh rupees, you can keep it as a lump sum. You keep it at Rs 12, but it keeps growing from the age of 35 to 60. So, in 25 years, this Rs 2 lakh will keep increasing and will become around Rs 4 crore. You started investing from 25 and continued till 35 only, after that you did not invest even a single penny and the same Rs 2 lakh which was your deposit at the age of 35, kept growing slowly at Rs 12, for the next 25 years, till the age of 60 you will have Rs 4 crore. Now if you again do SIP of Rs 00 and start at the age of 35 and continue doing the same for 25 years, that means by the age of 25 you will put Rs 00, you will have Rs 3 crore 80 lakh, even less than that. This is the benefit of investing early. Investing for only 10 years and then you did not invest for the rest of your life, even then you will have more money. In comparison, you invested double the amount, invested for 25 years but only Rs 10 crore."
