The 20-30-20 Rule: Plan Your ₹1 Crore Home Loan Clear, practical steps to make a ₹1 crore loan affordable — protect your cash flow, reduce interest, and use your home purchase to build long-term wealth. Why a simple rule matters Home loans shape your finances for decades. Without structure, EMIs can crowd out savings and increase stress. The 20-30-20 rule gives clear targets for down payment, monthly affordability, and sensible tenure so you can buy confidently. Rule component #1 — 20% Down Payment (₹20 Lakh) Aim for at least ₹20 lakh down on a ₹1 crore property. Benefits: lowers loan principal, reduces EMI, improves loan-to- value (LTV) and may secure better interest rates. Tip: Use a mix of savings, liquid investments, and any tax-free bonuses — avoid draining emergency funds. Rule component #2 — 30% EMI-to- Income Your monthly EMI should be no more than 30% of take-home income. This preserves space for living costs, investments, and emergencies. Example: If take-home is ₹1,50,000/month → target EMI ≤ ₹45,000. If EMI exceeds 30%: increase down payment, shorten wishlist, or extend co-borrower income. How EMI changes with loan size For a ₹80 lakh loan (after 20% down) approximate EMIs vary by interest rate and tenure. Use this as a quick guide — exact figures depend on your rate. 10-year tenure Higher EMI, much lower total interest — good if cash flow permits. 20-year tenure Balanced EMI and reasonable total interest — recommended default for many borrowers. 30-year tenure Lower EMI but much higher total interest; consider only if 30% rule otherwise breached. Fix Tenure Choose 20-year or adjust Test EMI Calc EMI at 30% income Set Down Payment Target 20% down Assess Finances Evaluate income and savings Follow the sequence to convert the rule into a concrete plan: evaluate income, secure down payment, test EMI vs income, then fix tenure or adjust inputs. Practical adjustments & levers Increase down payment to cut EMI and total interest. Negotiate rate or pick fixed vs floating based on risk appetite. Consider co-borrower income to improve affordability. Make occasional pre-payments from bonuses to shave years off the loan. Protect your plan — contingency and insurance Maintain an emergency fund of 6–12 months of household expenses. Take term life cover sized to outstanding loan and household needs. Consider EMI protection for job loss or critical illness — evaluate cost vs benefit. Next steps — make the numbers real Run an EMI calculator with your expected interest rate and 20-year tenure.
