7 Financial Rules: Memorize these 7 financial formulas, and you will never fail in life..

50/30/20 Rule: As soon as you start your job and receive your salary, this is the first rule you should follow. The 50/30/20 financial rule provides a sense of financial freedom not just at the start, but throughout your life. This rule suggests spending 50% of your earnings on necessities and 30% on fulfilling hobbies and desires. However, before making these expenditures, do not forget to allocate 20% of your income toward investments or savings.

4% Rule:

You should begin planning for retirement as soon as you start your career. The 4% financial rule states that you should withdraw only 4% of your accumulated retirement corpus during the first year of retirement. This withdrawal amount should be adjusted according to the inflation rate. For instance, if your retirement corpus is ₹1 crore, your withdrawal in the first year should be limited to ₹4 lakh.

Emergency Fund:

One of the most crucial financial rules is maintaining an emergency fund equivalent to at least 3 to 6 months of living expenses. Adversity strikes without warning; in the current climate—where job loss is a possibility—having such a fund ensures you can cover essential expenses, medical emergencies, and unforeseen needs without falling into a crisis.

1/3 Rent Rule:

Whether you live in a rented home or have taken a loan to buy or build your own house, you must keep one thing in mind: the associated cost should not exceed 33% of your monthly income. Keeping housing costs or rent at one-third of your income ensures that your other expenses and financial plans remain unaffected.

2x Investing Rule: Everyone appreciates luxury, and the growing craze for branded goods holds a strong appeal for young people. However, the 2x investing rule dictates that you should invest an amount equal to what you spend on luxuries. If you buy a pair of branded shoes worth ₹10,000, you should also invest ₹10,000. Naturally, you should only spend on personal indulgences if you are able to save an equivalent amount for the future.
