How Much EMI Can You Actually Afford? The 40% Rule Explained

Before a bank approves your loan, it runs one critical calculation: what percentage of your monthly income is already committed to EMI payments? This ratio — called FOIR, or Fixed Obligation to Income Ratio — is the single biggest determinant of how much you can borrow, and most applicants discover it only after rejection.

What is FOIR?

FOIR = (Total monthly fixed obligations ÷ Gross monthly income) × 100. Fixed obligations include all existing EMIs (home, car, personal loan, credit card minimum payments) plus the proposed new EMI. If your gross salary is ₹1 lakh and your total EMIs are ₹40,000, your FOIR is 40%.

The 40–50% threshold

Most Indian banks cap FOIR at 40–50% for salaried borrowers. PSU banks tend to be stricter (40%), private banks slightly more flexible (up to 55% for high-income profiles). Self-employed borrowers typically face a 40–45% cap due to income volatility. Exceeding the threshold results in automatic rejection or a reduced loan amount — not a higher rate.

Why 40% is the right personal limit

Beyond EMI comfort, consider: housing expenses (rent or maintenance), household costs, insurance premiums, children's education, and investments. A 40% EMI-to-income ratio, combined with 30% household expenses and 10% insurance/investments, leaves only 20% for everything else. At 50% FOIR, financial stress begins for most middle-class households.

How to calculate your own borrowing limit

Step 1: Find your net take-home salary (not gross). Step 2: Multiply by 0.40 — this is your maximum total monthly EMI budget. Step 3: Subtract all existing EMIs. Step 4: The remainder is the maximum new EMI you can take on. Step 5: Use an EMI calculator to reverse-engineer the loan amount this EMI supports at current rates.

The income components banks include and exclude

Banks typically use gross salary including basic, DA, and HRA. Variable components like performance bonuses, overtime, and LTA are usually excluded or counted at 50%. Rental income may be counted at 70–80% of actuals. Understanding what counts helps you present your income correctly to maximise eligibility.

Strategic moves to improve your FOIR

Close small outstanding loans before applying for a large one — even a ₹5,000/month two-wheeler EMI reduces your home loan eligibility by ₹4–5 lakh. Extend the tenure of the new loan to reduce the EMI (which improves FOIR even if total interest rises). Add a co-applicant with income to pool eligibility. These are the levers banks don't explain to you — but now you know.
