There are really only four variables you need to understand to figure out how much money you need to save each year to retire a millionaire:
- Your current age.
- The age that you will be when you retire.
- The return you think you'll get on your investment.
- The money you have saved to date that counts towards your goal.
Everything else being equal, the earlier you start saving the easier it is to hit that Crore Pati mark. That's because you've got compounding interest on your side.
