- I am 35 right now and I want to retire at around 45. Max 50. - I am in Software Development and I draw a good salary. - I am married and I dont plan to have any kids. - My monthly expenses are around 50-60k. - I own a house. What are the best retirement plans/schemes I can invest in? What other invest options I can explore? I already have Mutual funds in my portfolio as a long term SIP.
