How Banks Decide Your Home Loan Eligibility
When banks like SBI, HDFC, or ICICI evaluate your home loan application, they don't just look at the property value as collateral — they assess whether your income can comfortably support the monthly EMI alongside your existing financial obligations. The key metric they use is called the Fixed Obligation to Income Ratio (FOIR).
FOIR is the percentage of your net monthly income that goes toward fixed debt obligations such as existing EMIs, credit-card payments and the proposed loan EMI. A 50% FOIR assumption is used as an example in this calculator, not as a universal lender rule. If you earn ₹80,000/month, this illustrative ceiling is ₹40,000 across all loan EMIs. If you already have a car-loan EMI of ₹10,000, the illustrative remaining capacity for a new home-loan EMI is ₹30,000.
A Worked Example
Consider someone earning ₹1,00,000/month net salary with no existing loans. Using the calculator's 50% illustrative FOIR assumption, the estimated home-loan EMI capacity is ₹50,000/month. At an illustrative 8.5% home-loan rate over 20 years, this EMI capacity translates to an estimated loan amount of approximately ₹58 lakh. If the same person already has a ₹15,000/month car-loan EMI, the illustrative capacity falls to ₹35,000/month.
How to Increase Your Eligibility
The most direct lever is reducing or closing existing EMIs before applying — even paying off a small personal loan can meaningfully free up FOIR capacity. Adding a co-applicant with independent income (spouse, parent) combines both incomes for eligibility calculation, often the single biggest lever for increasing loan amount. Extending the loan tenure lowers the monthly EMI for the same loan amount, increasing how much principal fits within your FOIR cap — though this increases total interest paid over the loan's life. A strong CIBIL score (750+) can also unlock marginally better interest rates, which indirectly increases eligible loan amount for the same EMI capacity.
Why Different Banks Give Different Eligibility Numbers
FOIR caps and exact underwriting criteria vary by lender and borrower profile. Treat the 50% figure used here as an illustrative planning assumption and compare lender-specific eligibility, rates, fees and underwriting requirements before applying.

Home Loan Eligibility Formula
Banks use FOIR (Fixed Obligation to Income Ratio) — typically 40–50% of net income. Max EMI = Net Monthly Income × FOIR. Then back-calculate maximum loan from this EMI at the applicable rate and tenure.
