Increments generally depends on your capability and their requirement. It is between 15 to 50%.
If u r main person in project and u offer resignation, they may increase your salary as u want.
If u jump company after your increment , u will get good hike in new company.
Remember TCS can't make u earn 4 crore. In the onsite hardly they give u 1.5 lacks per month. U have to pay tax, your expenditure from this 1.5 only. I think u can save only 50k per month.
The only way to earn enough money is from the onsite, u can jump to a MNC company and try to be in US for 10 years. It increases your chances of earning.
Marrying a girl from your comapny makes your target easy. 2 crores in 10 years may be not difficult, she may earn another 2 crore.
Try to provide quality service, automatically money and fame follows you.
ALL THE BEST.
