10 Personal Finance Rules for Better Financial Decisions

10 Personal Finance Rules

When we invest in fixed income schemes, mutual funds, money-back plans and similar financial instrument, the primary thought that often crosses our minds is when our money will double. So, this rule of 72 will help us to estimates the number of years it takes to double your money at a specified rate of return.

To use the rule of 72, you divide 72 by the annual rate of return. The result provides an  approximation of the number of years required for your investment to double. 

According to this rule, you should subtract your age from 100 and allocate that percentage of your portfolio to investments in stocks and the remaining should be invested in more stable investments like bonds. 

It’s crucial to understand that the “100 Minus Age Rule” is a general guideline and may not be suitable for everyone’s unique need hence one’s approach should be as per their personal liabilities, loans and goals. 

It is a well-known rule for budgeting. As per this rule you should divide your after-tax income into 3 parts:  

  • 50% on Needs (pay your rents, bills, groceries and other utilities) 
  • 30% on Wants (shopping, vacation, party, hobbies and self-wellness) 
  • 20% on Savings and Debt Repayment (Retirement, investments, creating emergency funds)

According to this rule one should keep minimum 6 times of your current monthly expense as emergency fund. These reserves can be kept in saving account (using auto sweep _ to gain more interest rate) or any other easily accessible liquid assets platform. 

According to the 6x emergency rule, you should have an emergency fund of $18,000. This fund acts as a financial safety net, providing you with enough resources to cover living expenses for approximately six months in case of unexpected situations like job loss, medical emergencies, or unforeseen expenses.  

As per this rule one should take life insurance which covers twenty times of your current salary.  

According to the 20x insurance rule, you would aim to have life insurance coverage of $1,000,000.  

As per this rule, the combined EMIs (Equated Monthly Installments) for all your loans should not surpass 40% of your income. 

This rule assists us in calculating the amount of money needed to save for retirement. According to this rule, you should keep 25 times of your yearly expense in the saving account by the time of your retirement. You can withdraw approx. 4% of your savings (as interest) annually in retirement to maintain a sustainable income throughout your retirement years. 

So, based on the 25X rule, you would aim to have $1,000,000 in savings by the time you retire. This assumes that withdrawing 4% of this amount each year, or $40,000 (4% of $1,000,000), should provide a sustainable income throughout your retirement years. 

Note: This rule fits better when the person retires around 60 years.  

As per this rule one should invest first and spend later. It involves dedicating part of your income to investments during the first week of the month, while the rest is allocated for expenses.

As per this plan, we should first invest in 3 essentials things (Health Insurance, Life Insurance and Emergency funds) and then 3 personalized or need based things (Debt prepayment, retirement planning like National Pension Scheme, Sovereign Gold Bonds) and then comes 3 investments such as Real Estate, Stocks, Mutual Funds 

Similar to the rule of 72, this rule will help you calculate how many years it will take to make your money triple. 

To use the rule of 114, you divide 114 by the annual rate of return. The result provides an  approximation of the number of years required for your investment to triple. 

Let us assume that we have an investment with an annual rate of return of 6% then, 

Years to Triple=114 / Annual Rate of Return

So, according to the Rule of 114, it would take approximately 19 years for your money to triple with a 6% annual rate of return.
