In London, might move to India (need help on salary/savings)

I am not from India, moved to London 4.5y ago and I'm considering a move to India.

But I struggle to understand the relationship between salaries <> lifestyle <> money saved each month.

Would be cool to learn everyone's salary, but also your lifestyle and how much you save per month. Can you help with the following template?

Role: City: Salary: Rent: Food: Transport: Savings per month:

Any other costs I should factor in that you feel are necessary to consider?

Thanks for the help!
