Nine rules of Personal Finance that every individual should know:

- Rule of 72 (Double Your Money)
- Rule of 70 (Inflation)
- 4% Withdrawal Rule
- 100 Minus Age Rule
- 10-5-3 Rule
- 50-30-20 Rule
- 3x Emergency Rule
- 40% EMI Rule
- Life Insurance Rule

#### Rule of 72

Definition: Number of years required to double your money at a given rate of interest.

Divide 72 by the interest rate.For example, if an individual wants to know the time it will take to double his money at 9% interest, divide 72 by 9 = 8 years

At a 6% rate, it will take 12 years

At an 8% rate, it will take 9 years#### Rule of 70

Definition: The number of years the savings will be reduced to half its present value at a given rate of inflation.

Divide 70 by the current inflation rate.For example, the inflation rate of 7% will reduce the value of your money to half in 10 years.

#### 4% Rule for Financial Freedom

Definition: To take the VRS (Voluntary Retirement Scheme), the required corpus is 25 times the estimated Annual Expenses.

For example, if an individual’s estimated annual expense after 50 years of age is INR 500,000 and he/she wishes to take VRS then the required corpus is INR 12,500,000.

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

Withdraw 4% every year, i.e. INR 500,000

This personal finance rule works 96% of the time over 30 years of the period.

#### 100 minus age Rule

Definition: Percentage allocation of investment in equity should not be more than (100 – age) %

This rule is used for asset allocation to help determine the risk-taking capacity of the individual.For example, if the age of an individual is 30 years, then 100 – 30 = 70

Equity: 70%

Debt: 30%But if the age is 60, 100 – 60 = 40

Equity: 40%

Debt: 60%#### 10-5-3 Rule

Definition: Return expectation from the equity segment is 10%, the debt segment is 5%, and savings is 3%.

One should have reasonable returns expectationsEquity and Mutual Funds – 10%

Debts and Fixed deposits – 5% Debts

Savings Account – 3%#### 50-30-20 Rule

Definition: The earnings should be allocated in the ratio 50:30:20 for Needs, Wants, and Savings respectively.

This rule helps an individual to better allocate (spend) the monthly earnings.

50% – Needs (Groceries, rent, EMIs, etc)

30% – Wants (Entertainment, vacations, etc)

20% – Savings (Equity, MFs, Debt, FDs, etc)At least try to save 20% of your income, one can save more than this percentage.

#### 3x Emergency Rule

Definition: An individual should always have 3 times the fixed monthly income in the emergency fund.

An emergency fund should only be used in case of loss of employment, medical emergency, or any other catastrophic situation.

A better case scenario would be to have 6 times monthly income in liquid or near liquid assets.

#### 40% EMI Rule

Definition: The total amount of monthly EMIs should not be more than 40% of the monthly income.

For example, if an individual earns INR 50,000 per month the total amount of all the EMIs should not be more than INR 20,000.

This Personal Finance Rule is commonly used by financial institutions to provide loans.

#### Life Insurance Rule

Definition: The assured sum should be at least 20 times the annual income.

For example, if an individual earns INR 1,000,000 annually the assured sum should be at least INR 20,000,000.

These personal finance rules are equally useful for individuals of any age.
