Type “home loan” into Google and the very next word people add is usually “EMI calculator” — but that puts the cart before the horse. Before you can calculate what your monthly payment will be, the bank has already decided the one number that actually matters: how much it will lend you in the first place. That number is your home loan eligibility, and most first-time borrowers have no idea how it’s actually worked out.
Banks don’t just look at your salary and hand you a number. They run it through one of two formulas — the FOIR method (Fixed Obligation to Income Ratio) or the income multiplier method — and both can swing your eligible loan amount by lakhs depending on your existing EMIs, your age, and the tenure you choose. This guide walks through exactly how each method works, with real worked examples, so you know your number before you ever walk into a branch.
How Banks Actually Calculate Home Loan Eligibility
Most Indian lenders use one of two approaches, and it’s worth knowing both because different banks lean on different ones.
1. The FOIR Method (Fixed Obligation to Income Ratio)
This is the most common approach used by banks and housing finance companies. FOIR caps the total of all your EMIs — the new home loan plus anything you’re already paying — at a fixed percentage of your net (take-home) monthly income. That percentage typically falls between 40% and 55%, depending on the lender and your income slab (higher earners are often allowed a slightly higher FOIR).
The formula works in two steps:
Step 1 — Maximum EMI you can afford = Net Monthly Income × FOIR% − Existing EMIs
Step 2 — Maximum Loan Amount = Maximum EMI × Loan Factor (based on interest rate and tenure)
The “loan factor” in Step 2 is really just the EMI formula used in reverse. Our Mortgage Loan Calculator uses the same underlying formula to go from loan amount → EMI; eligibility calculations simply run it backward, from EMI → loan amount.
2. The Income Multiplier Method
Some banks skip the EMI math entirely and just multiply your annual (or monthly) income by a fixed factor — commonly somewhere between 5x and 6x your gross annual income for salaried applicants. It’s a cruder rule of thumb, which is exactly why two banks can quote you two very different eligibility figures for the identical salary slip.
Worked Example 1: Eligibility From Your Salary Alone
Say you earn a net take-home salary of ₹80,000 per month, have no existing loans, and the bank applies a FOIR of 50% for a 20-year tenure at 8.5% annual interest.
- Maximum EMI = ₹80,000 × 50% = ₹40,000/month
- At 8.5% for 20 years, every ₹1 of monthly EMI supports roughly ₹115.25 of loan principal (this is the reverse-EMI factor — at this rate/tenure, EMI works out to about ₹868 per ₹1 lakh borrowed)
- Maximum Loan Amount = ₹40,000 × 115.25 ≈ ₹46.1 lakh
Using the income multiplier method instead — say the bank applies 6x your gross annual income of roughly ₹9.6 lakh (₹80,000 × 12) — you’d land closer to ₹48 lakh. Close, but not identical, which is exactly why it’s worth asking your bank which method it uses before you start house-hunting with a number in mind.
Worked Example 2: How One Existing EMI Changes Everything
Now take the same ₹80,000/month salary, same 50% FOIR, same 20-year tenure — but this time you’re already paying ₹15,000/month toward a car loan.
- Maximum total EMI allowed = ₹80,000 × 50% = ₹40,000
- Remaining EMI capacity for the home loan = ₹40,000 − ₹15,000 = ₹25,000/month
- Maximum Loan Amount = ₹25,000 × 115.25 ≈ ₹28.8 lakh
A single ₹15,000 car EMI just cut your home loan eligibility by nearly 37% — from ₹46.1 lakh down to ₹28.8 lakh — even though your salary hasn’t changed at all. This is the single biggest reason loan officers ask for your last 6 months of bank statements: they’re hunting for exactly this kind of existing obligation before they quote you a number.
Worked Example 3: Why Your Age Matters as Much as Your Income
Banks cap your loan tenure at (retirement age − your current age), usually assuming retirement at 60 for salaried applicants. That cap changes your “loan factor” even if every other number stays the same.
Take a 45-year-old borrower with the same ₹40,000 maximum EMI capacity as Example 1. Because they’re 45, the bank will only offer a maximum 15-year tenure instead of 20:
- At 8.5% for 15 years, the reverse-EMI factor drops to roughly ₹101.6 per ₹1 of EMI (versus ₹115.25 for 20 years)
- Maximum Loan Amount = ₹40,000 × 101.6 ≈ ₹40.6 lakh
That’s about 12% less eligibility than the 35-year-old in Example 1, purely because of the shorter tenure a bank is willing to offer someone closer to retirement — the monthly EMI budget is identical, but there are fewer months to spread the repayment across.
Home Loan Eligibility by Monthly Salary (Reference Table)
Assuming a 50% FOIR, no existing EMIs, an 8.5% interest rate, and a 20-year tenure, here’s roughly what different salary levels translate to:
| Net Monthly Salary | Max EMI (50% FOIR) | Approx. Loan Eligibility |
|---|---|---|
| ₹50,000 | ₹25,000 | ≈ ₹28.8 lakh |
| ₹75,000 | ₹37,500 | ≈ ₹43.2 lakh |
| ₹1,00,000 | ₹50,000 | ≈ ₹57.6 lakh |
| ₹1,50,000 | ₹75,000 | ≈ ₹86.4 lakh |
| ₹2,00,000 | ₹1,00,000 | ≈ ₹1.15 crore |
These are indicative figures — your actual eligibility will depend on the bank’s specific FOIR slab, your credit score, and any existing obligations.

What Else Affects Your Eligibility
Credit score: A CIBIL score above 750 doesn’t just get you approved faster — many lenders will stretch their FOIR slab upward (sometimes to 55-60%) for applicants with strong scores, directly increasing eligibility. A score below 650 can do the opposite, or trigger a higher interest rate that shrinks your loan factor.
Employment type: Self-employed applicants are usually assessed on average income over the last 2-3 years of ITRs rather than a single payslip, and banks often apply a slightly more conservative FOIR to account for income variability.
Co-applicant income: Adding a spouse or parent as a co-applicant lets the bank combine both incomes for the FOIR calculation, which is one of the fastest ways to raise eligibility without touching your own salary.
Existing loans and credit card usage: Every active EMI — car loan, personal loan, even a large ongoing “no-cost EMI” purchase — reduces your remaining EMI capacity exactly as shown in Example 2 above. Paying off or closing a small loan before applying can meaningfully raise what you qualify for.
How to Increase Your Home Loan Eligibility
- Add a co-applicant with a steady income to combine both salaries for the FOIR calculation.
- Pay down or close existing EMIs — even a small personal loan can free up meaningful EMI capacity.
- Choose a longer tenure if your age allows it — a longer tenure lowers the EMI for the same loan amount, which raises how much loan that EMI budget can support.
- Improve your credit score before applying — this can shift you into a better FOIR slab and a lower interest rate at the same time.
- Time large purchases carefully — avoid taking on a new EMI (even a “no-cost” one) in the months right before you apply for a home loan.
Frequently Asked Questions
What FOIR percentage do most Indian banks use?
Most banks and housing finance companies use a FOIR between 40% and 55% of net monthly income, with higher-income applicants often getting a slightly higher slab. It varies by lender, so it’s worth asking directly or comparing at least two or three offers.
Does my credit score really change how much I can borrow?
Yes. Beyond just approval or rejection, a strong CIBIL score (750+) can push a lender into a higher FOIR slab and a lower interest rate — both of which directly increase your maximum eligible loan amount, not just your chances of approval.
Is loan eligibility the same as the sanctioned loan amount?
Not necessarily. Eligibility is the maximum the bank’s income-based formula allows; the final sanctioned amount can be lower if the property’s market valuation is less than the loan you’re eligible for, since banks also cap the loan at a percentage of the property value (the Loan-to-Value or LTV ratio).
Can self-employed applicants get the same eligibility as salaried applicants?
It’s possible, but self-employed income is assessed differently — usually as an average of the last 2-3 years of tax returns rather than a fixed monthly figure — and banks often apply a more conservative FOIR to account for income that can vary year to year.
How much does a longer tenure actually help my eligibility?
Quite a lot. As shown in Example 3 above, extending a loan from 15 to 20 years at the same interest rate raised eligibility by about 12% for an identical EMI budget — because the same monthly payment is spread over more months, supporting a larger principal.
