Personal Finance Fundamentals

Finance Rules

Timeless formulas that separate wealth builders from salary spenders — with real examples and working calculators for each.

Pay Yourself First

Move a fixed amount to savings the moment salary arrives — before rent, before groceries, before anything else.

The 50-30-20 Rule

Allocate 50% of your income to needs, 30% to wants, and 20% to savings and investments.

Divide 72 by your annual return rate to find how many years it takes to double your money.

Emergency Fund First

Before investing a single rupee, build 6 months of expenses in a liquid account.

Inflation is Your Enemy

At 6% inflation, ₹1 lakh today becomes ₹56,000 in purchasing power in 10 years.

Time in Market Beats Timing

The investor who starts 5 years earlier consistently beats the investor who 'waits for the right time'.

Savings Rate Over Returns

Your savings rate has 5x more impact on wealth than your investment returns.

Insurance is Not Investment

Buy term insurance for protection. Invest separately for wealth. Never mix the two.

Step Up Every Year

Increase your SIP by 10% every year when your salary increases.

Track Your Net Worth

Calculate your net worth every 6 months. Assets minus liabilities equals your financial score.

Debt Destroys Wealth

Consumer debt at 18-24% interest destroys wealth faster than any investment can build it.

Start Before You Are Ready

The most expensive investment mistake is waiting until you have enough money, knowledge, or time to start.
