1) Rule of 72*

No. of yrs required to double your money at a given rate, U just divide 72 by interest rate Eg, if you want to know how long it will take to double your money at 8% interest, divide 72 by 8 and get 9 yrs

At 6% rate, it will take 12 yrs
At 9% rate, it will take 8 yrs

2) Rule of 70*

Divide 70 by current inflation rate to know how fast the value of your investment will get reduced to half its present value.

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

3) 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.

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%

5) 10-5-3 Rule*

10â„… Rate of return - Equity / Mutual Funds 5â„… - Debts ( Fixed Deposits or Other Debt instruments) 3â„… - Savings Account
