My total monthly SIP is of Rs 22,000, I can increase Rs 500 in each fund (i.e. 15% step up) every year based on my salary. For the next 13-15 years I can take high risk out of 23 years. My other investments are PF (21600(employer) + 21600(employee)) yearly and can start Rs 50,000 yearly in NPS for tax saving.

Looking for a combined corpus of 8-10 crore till retirement for my child's education (1 year old) and for my retirement savings, Can I achieve this with my SIP and other investments?

Kindly guide /provide your expert opinion whether any of my funds are overlapping or needs to be discontinued or any new funds needs to be added to meet my target corpus.
