Great idea! Assuming you get a rate of 15% in the long run, you can hit a corpus of Rs 3.03 crores over 20 years. Go for a mix of Large cap and Multicap equity funds. Based on your risk profile you may add midcap funds too.
Note that not investing in Direct Plan Mutual funds can reduce your corpus by almost 60 lakhs!
