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 โ 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 all fixed debt obligations combined โ existing EMIs, credit card minimum payments, and the new loan you're applying for. Most lenders cap this at 50% of your net monthly income. If you earn โน80,000/month, your total EMI capacity across all loans is capped around โน40,000. If you already have a car loan EMI of โน10,000, your remaining capacity for a new home loan EMI is limited to โน30,000.
A Worked Example
Consider someone earning โน1,00,000/month net salary with no existing loans. At a 50% FOIR cap, their maximum home loan EMI capacity is โน50,000/month. At a typical home loan rate of 8.5% over 20 years, this EMI capacity translates to an eligible loan amount of approximately โน58 lakh. If this same person already has a โน15,000/month car loan EMI, their available capacity drops to โน35,000/month โ reducing eligible home loan amount to roughly โน41 lakh, a difference of โน17 lakh purely due to the existing obligation.
How to Increase Your Eligibility
The most direct lever is reducing or closing existing EMIs before applying โ 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 โ 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 โ some banks use 50%, others 55% or even 60% for higher-income applicants with strong credit profiles. This is why getting eligibility quotes from 2-3 different lenders before committing to one is a worthwhile exercise; the difference in eligible loan amount between lenders can be substantial for the same income profile.
