Thanks for response and comments.
As you said, bit of tweaking is required to FIRE in India. Looking forward to it.
Yesterday started budgeting expenses and cost of living in India to accurate level eventhough planned finances an year back with lot of buffer.
Found an excel template to track budget and expenses. It took time to configure and good to track things to accuracy atleast for an year after FIRE to get idea on expenses.
As part of that, trying to figure out cost of living now a days in India. For all fixed expenses, got a clarity as I was living in India before moving to UK couple of years back. Only changing parts are groceries cost and new life style costs like more travel, family time, partying etc.
Forgot to mention in my earlier post in this topic.. out of 20 years of my career, I ensured half of my time living in India so no problem for me or my family to go back and live in India.
