Would you be able to retire with Rs. 2Cr ?

If you are single, maybe yes. But if you have family, then very tough.

Because money value go down every year. If today your monthly expense is ₹50,000, after 7-10 years it become ₹1 lakh. Again after 7-10 years, it become ₹2 lakh. Then ₹4 lakh… so money finish fast.

2 crore look big now, but after 10-20 years, not enough. If you do some freelance work, maybe you manage for some more years. But full retirement with family , very hard.
