80LPA in India or 320k in Bay Area?

Using the 5X multiple on purchasing power parity and considering taxes in Bay Area and india are quite similar - I would say 80LPA in India is ‘richer’ than 320K in the Bay Area.

It’s still possible you may have more savings in the US if you live a very frugal life in the bay. But all in all you possibly are going to feel richer in India

Assume you save 50% post tax in both cases which is pretty low for someone making 80LPA. You would be saving 27L in India and 112k (92L) in bay area. Let's say you feel you might just be saving 25% in bay area and 50% in India post tax. You will still be saving ~75% than you would in India. More importantly I don't think purchase parity world 1:1. It works only on some stuff like food and rent. Traveling, electronics, cars, most luxuries cost the same in every country. It might in fact cost more in India than in the US. There is no rational reason to live in India when you have a choice to live in US. And if in 5 years, you feel like coming back to India for emotional reasons, you will still be 5-6 years ahead in your retirement plan compared to if you stayed in India.

What job role is paying 80LPA if you don’t mind

Staying here sounds better if you get to work in one of the well funded startups and earn that kind of money
