Goals
1- Child Education- 30 to 40 Lac ( 15 to 18 yrs)
2- New Home Down Paymnt - 10 to 12 Lac ( 5 yrs )
3- Retirement Planning - Yet not decided (Confused)
Child Education -
If you invest 6,940 per month for a period of 18 years then you will get 40 Lakhs in 18 year @ 10% return (I feel that's only possible).
