• A car in India is a huge expense but you get a car in the US for very % of your annual salary

• Healthcare in India is affordable and accessible but if you or your loved ones get a disease that requires specialists, you might require a huge amount of money even with Insurance. This isn’t exactly true in the US

• Services — Maids, Drivers, Urbanclap are extremely cheap in India compared to US

• Travel is cheaper in the US

• Education quality in government schools is really good in most places in the US so most people send their kids to these schools. A child’s education is a good % of your monthly income in India since you can send them only to private schools.

This calculation needs to happen based on your needs, your future plans and other factors.
