Inflation rate of 7% will reduce the value of your money to half in 10 years.


4% Rule for Financial Freedom

Corpus Reqd = 25 times of your estimated Annual Expenses.

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 cr.

Put 50% of this into fixed income & 50% into equity.

Withdraw 4% every yr, i.e.5 lac.

This rule works for 96% of time in 30 yr period

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%

One should have reasonable returns expectations

10% Rate of return – Equity / Mutual Funds

5% – Debts ( Fixed Deposits or Other Debt instruments)

3% – Savings Account

Atleast try to save 20% of your income.
