When you visit a doctor for an annual checkup, they don't just look at you and guess if you are healthy. They run a blood test, measure your blood pressure, and calculate your BMI.
Your financial health works exactly the same way. You cannot look at your bank balance on a random Tuesday and declare that you are "doing fine." You need hard, mathematical metrics to diagnose if your wealth is growing or decaying.
Corporate CFOs use financial ratios to determine if a company is healthy. You are the CFO of your own life. Here are the 7 personal finance ratios you must calculate today.
Key Takeaways
- The Savings Ratio (Aim for 20%+): This is the ultimate wealth indicator. If you save 0% of a ₹2 Lakh salary, you are financially weaker than someone saving 30% of a ₹50,000 salary.
- Debt-to-Income Ratio (Keep under 30%): If your EMIs consume more than 40% of your take-home pay, you are in the danger zone.
- Liquid Asset Ratio (Aim for 6 Months): Can you survive a job loss? This ratio proves it.
- Net Worth to Income Ratio: Are you actually accumulating wealth as you get older, or just inflating your lifestyle?
1. The Savings Ratio (The Wealth Engine)
Formula: (Monthly Savings / Monthly Take-Home Pay) * 100 Target: 20% to 30% minimum.
This is the most critical ratio in personal finance. It tells you exactly how much of your labor you are actually keeping. If you earn ₹1 Lakh a month and save ₹25,000, your savings ratio is 25%. If your savings ratio is below 10%, you are one medical emergency away from debt. If you want to retire early (FIRE), you need to push this ratio to 40% or 50%.

2. Debt-to-Income (DTI) Ratio (The Stress Indicator)
Formula: (Total Monthly EMI Payments / Monthly Take-Home Pay) * 100 Target: Under 30% (Under 40% if you have a home loan).
Banks use this ratio to decide if they will give you a loan. If your take-home pay is ₹1 Lakh, and you pay ₹30,000 for a home loan EMI and ₹15,000 for a car EMI, your DTI is 45%. A DTI above 40% means you are heavily leveraged. Any disruption to your income will immediately trigger a default. If your DTI is high, pause all investments and aggressively pay down debt.
3. Liquid Asset Ratio (The Survival Metric)
Formula: Total Liquid Assets / Monthly Expenses Target: 6 to 12 Months.
Your liquid assets are cash, FDs, and mutual funds—things you can convert to cash within 48 hours without taking a penalty. If your monthly expenses are ₹50,000, and you have ₹3 Lakhs in liquid assets, your ratio is 6. This means if you lose your job today, you can survive for exactly 6 months. (Your ₹1 Crore house does not count here, because you cannot eat drywall).
4. Housing Cost Ratio (The Lifestyle Trap)
Formula: (Monthly Rent or Home Loan EMI / Monthly Take-Home Pay) * 100 Target: Maximum 30%.
Housing is the biggest expense for Indians. If your rent or EMI is consuming 50% of your salary, you will mathematically struggle to invest or enjoy your life. If you live in a Tier-1 city like Mumbai and this ratio hits 40%, you must find flatmates or downsize immediately.
5. Solvency Ratio (The Bankruptcy Check)
Formula: Total Net Worth / Total Assets Target: Greater than 50%.
This ratio tells you how much of your assets you actually own versus how much the bank owns. If you own a ₹1 Crore house, but you have an ₹80 Lakh home loan on it, your net worth in the house is only ₹20 Lakhs. Your solvency ratio is 20%. The closer this number is to 100%, the closer you are to absolute financial freedom.

6. Life Insurance Coverage Ratio (The Family Shield)
Formula: Total Term Insurance Cover / Annual Income Target: 15x to 20x.
If you earn ₹10 Lakhs a year, you should have a Pure Term Life Insurance cover of at least ₹1.5 Crores. If your ratio is only 2x (e.g., your company provides a ₹20 Lakh corporate cover), your family is severely exposed to risk if you pass away.
7. Investment Asset Ratio (The Growth Check)
Formula: (Invested Assets / Total Net Worth) * 100 Target: 50%+ (Excluding your primary residence).
If your entire net worth is sitting in a savings account earning 3%, your money is dying to inflation. You need at least 50% of your liquid wealth invested in growth assets (Equity Mutual Funds, Stocks, SGBs) to ensure your money is working harder than you are.
