Personal Finance Thumb Rules

Let's dive into the seven essential personal finance thumb rules:

1. Emergency Fund: Your Financial Safety Net

An emergency fund is a crucial pillar of any solid financial plan. It acts as a safety cushion during unexpected crises, such as sudden job loss, medical emergencies, or urgent car repairs.

The general thumb rule suggests maintaining an emergency fund equivalent to six months of your salary. However, remember that personal circumstances vary.

For instance, if you have a stable job, you might consider three months’ worth of expenses. On the other hand, if you’re in a field with more uncertainty, like being self-employed or freelancing, aiming for a year’s worth of expenses could provide greater security.

Example: Imagine you unexpectedly lose your job. When you have a good amount of money saved up for unexpected situations, you can pay for your basic needs while you hunt for a new job. It lowers stress and helps you concentrate on finding the best opportunity.

2. Term Insurance Coverage: Safeguarding Your Loved One's

Life insurance is a basic tool to guarantee your family gets financial help if someone passes away unexpectedly. While there are various methods to calculate your insurance needs, a practical thumb rule suggests getting coverage equal to at least ten times your annual income.

Example: Consider a scenario where the primary breadwinner of a family passes away unexpectedly. A well-chosen term insurance policy can help replace the lost income, easing financial burdens and allowing the family to maintain their standard of living during a challenging time.

3. Portfolio Equity Allocation: Balancing Risk and Reward

The Rule of 100 offers a simple guideline for determining the percentage of equity (stocks) in your investment portfolio based on your age. Subtract your age from 100, and that’s the percentage of your portfolio that could be allocated to equities.

For instance, at 30 years old, around 70% of your portfolio might be in equities, while at 50, it could be 50%.

Example: Consider that you’re in your early twenties and can give your investments many years to flourish. Deciding to have higher equity allocation matches your long-term goals, allowing you to take advantage of the potential increase in stock value over the years.

4. Debt-to-Income Ratio: Managing Borrowings Wisely

The debt-to-income ratio acts as a crucial guideline, recommending that your monthly loan EMI payments stay within 35-40% of your income. It makes sure you have enough money left over after your regular expenses to save for the future.

Example: Suppose you’re considering taking on a new loan for a major purchase. When you calculate your debt-to-income ratio, you can tell if you can easily manage the new monthly payment with your other financial commitments.

5. Rule of 72: Grasping Investment Timeframes

The Rule of 72 is a smart trick to estimate the time an investment needs to double its value. By dividing 72 by the annual rate of return, you can get an approximate idea of how many years it might take for your investment to double. For instance, with an annual return of 8%, your investment could double in roughly nine years.

Example: Imagine you’re saving for a down payment on a house. Understanding the Rule of 72 helps you project how your savings might grow over time and plan accordingly to achieve your homeownership goal.

6. 50/30/20 Rule for Budgeting: Balancing Your Financial Allocations

Allocate 50% of your income to needs (essentials like housing and utilities), 30% to wants (discretionary spending like entertainment), and 20% to savings and debt repayment.

Example: With a monthly income of ₹100,000, allocate ₹ 50,000 (50%) for essential expenses like rent and utilities. Reserve ₹30,000 (30%) for enjoyable activities such as dining out and entertainment. Put aside ₹20,000 (20%) for savings and paying off credit card debt, creating a balanced financial plan.

7. 20/4/10 Rule for Car Purchases: Navigating Optimal Auto Financing

Put down at least 20% of the car’s purchase price as a down payment, finance the car for no more than 4 years, and keep the total monthly car expenses (including loan payment and insurance) within 10% of your gross income.

Example: Let’s assume your annual salary is ₹8 lakhs. If you’re considering a car priced at ₹10 lakhs. Begin with a down payment of ₹2 lakhs (20%). Spread the remaining ₹8 lakhs over a 4-year financing period. It ensures that your total monthly car expenses, including the loan instalment and insurance, stay within ₹6,666.7 (10% of your monthly income). By following this guideline, you can confidently choose a car that aligns with your financial situation, avoiding excessive financial strain.
