Eg- if your annual expense after 50 years of age is 500,000 and you wish to take VRS then corpus with you required is 1.25 crore.

4) 100 minus your age rule


This rule is used for asset allocation. Subtract your age from 100 to find out, how much of your portfolio should be allocated to equities


Suppose your Age is 30 so (100 - 30 = 70)


Equity : 70%

Debt : 30%


But if your Age is 60 so (100 - 60 = 40)


Equity : 40%

Debt : 60%
