📊 5 Personal Finance Formulas Everyone Should Know
Managing money isn’t about how much you earn — it’s about how wisely you manage it.
Here are 5 simple personal finance formulas that can help you build stability, reduce stress, and grow wealth over time 👇
1️⃣ The 50 – 30 – 20 Rule
A smart way to divide your income:
50% Needs → rent, utilities, food, transport
30% Wants → entertainment, dining, lifestyle
20% Invest / Save → investments, savings, retirement
📌 This keeps spending balanced while ensuring consistent investing.
2️⃣ Emergency Fund Formula
💰 Save at least 6 months of your monthly expenses
Why?
1) Protects you from job loss or emergencies
2) Prevents borrowing or debt during tough times
📌 Financial security starts with preparedness.
3️⃣ Credit Card Usage Rule
💳 Use only up to 30% of your credit card limit
Benefits:
Maintains a healthy credit score
Reduces interest burden
Shows financial discipline
📌 Credit cards are tools, not extra income.
4️⃣ Debt Repayment Priority
📉 Pay off the highest interest loan first
This strategy:
Minimizes total interest paid
Speeds up debt freedom

📌 High interest = high risk. Eliminate it early.
5️⃣ Rule of 72
📈 72 ÷ Interest Rate = Years to double your money
Example:
8% return → 72 ÷ 8 = 9 years
📌 A quick way to understand the power of compounding.
