How Is Home Loan Eligibility Calculated on Salary? The Complete FOIR & Multiplier Breakdown

The exact formulas lenders use — FOIR, income multiplier, and LTV — with worked examples so you can estimate your own number before you apply

"How much home loan can I get?" is usually answered with a rough guess — a multiple of salary, a number a friend mentioned, a figure from a quick online calculator. But lenders don't decide eligibility on guesswork. They run your salary through two or three specific formulas, compare the results, and offer you the lower of the outputs. This guide walks through those formulas step by step, with real numbers, so you can estimate your own eligibility before you sit down with a lender.

Method 1: FOIR — Fixed Obligation to Income Ratio

FOIR measures what share of your net monthly income is already committed — or would be committed — to loan repayments. It is the primary gatekeeper most Indian lenders use for salaried applicants.

Step by step: how FOIR sets your maximum EMI - 

•  Start with your net monthly income — salary after statutory deductions (PF, professional tax), not gross CTC.
•  Apply the lender's FOIR cap — commonly 50%, sometimes higher for higher-income slabs or lower for informal/thin-file profiles.
•  Multiply: Net Income × FOIR Cap = Maximum total EMI you can carry across all loans.
•  Subtract any existing EMIs — car loan, personal loan, credit card minimums — to find what's left for the home loan.
•  That remaining figure is your Maximum Home Loan EMI, which is then converted into a loan amount using the interest rate and tenure.

Method 2: Income Multiplier - 

Alongside FOIR, many lenders apply a simpler benchmark: a fixed multiple of your net monthly or annual income. This method is faster to apply and often used as a sanity check against the FOIR result.

On a ₹60,000 net monthly salary, a 60× multiplier suggests eligibility of around ₹36 lakh — broadly in line with the FOIR-based Example 1 above. Lenders typically take whichever of the two methods produces the lower figure, since both are meant to be reasonable safety checks, not targets to maximise.

Method 3: Loan-to-Value (LTV) — the Property-Side Cap - 

Even if your income supports a larger EMI, the loan amount is also capped by the property's value. RBI-linked LTV norms mean the loan is usually capped at 75%–90% of the property value depending on the loan size, with the remainder funded as your own contribution (down payment). Your final eligibility is the lowest of the income-based figure and the LTV-based figure.

Putting It Together: A Full Worked Example

What Counts as "Net Income" — and What Doesn't

Usually included - 

•  Basic salary and dearness allowance
•  Fixed monthly allowances — HRA, conveyance, special allowance
•  Regular, documented rental income, where declared
•  A portion of consistent, recurring bonus or variable pay, at some lenders' discretion Usually excluded or partially weighted
•  One-time bonuses or irregular incentives
•  Reimbursements that aren't part of fixed pay
•  Income from sources the lender cannot independently verify

What Existing EMIs Reduce Your Eligibility

•   Car, two-wheeler or personal loan EMIs
•   Credit card outstanding, typically counted at 5% of the total balance as a monthly obligation
•   Education loan EMIs, your own or as a co-borrower
•   Any loan where you are a guarantor may also be factored in by some lenders

Five Ways to Increase Your Eligibility

•    Close or reduce high-EMI debt before applying — every ₹5,000 in cleared EMI meaningfully raises your home loan ceiling.
•    Add a co-applicant with a stable income — most lenders combine both incomes for the FOIR and multiplier calculation.
•    Choose a longer tenure — it lowers the EMI for the same loan amount, though it raises total interest paid.
•    Declare all verifiable income sources — documented rental income or a second job can lift the base number.
•    Improve your CIBIL score — a stronger score can move you into a lender's higher FOIR band and a better rate.

A Word of Caution

These formulas give a realistic estimate, not a guarantee. The final sanctioned amount depends on the lender's internal policy, the specific property, verification of your documents, and your complete credit profile. Be cautious of any online calculator or agent promising a fixed number without reviewing your actual salary slips, bank statements and credit report.

Frequently Asked Questions (FAQs)

Q. What is a good FOIR for a home loan?

Most lenders are comfortable at a FOIR of 40%–50% of net income. Some extend this to 55%–60% for higher-income applicants with strong credit profiles, since a larger absolute income leaves more room for essential expenses even at a higher ratio.

Q. Does gross salary or net salary matter for eligibility?

Net salary — income after statutory deductions such as provident fund and professional tax — is what lenders use. Gross CTC figures, which include non-cash components, typically overstate what's actually usable for EMI calculations.

Q. How much does an existing loan reduce my eligibility?

Every rupee of existing EMI directly reduces the EMI available for the new home loan, rupee for rupee, before the loan amount is calculated. A ₹10,000 existing EMI can reduce eligibility by roughly ₹11–13 lakh on typical rate and tenure assumptions.

Q. Can a co-applicant increase my eligibility significantly?

Yes. When a co-applicant's income is combined for the FOIR or multiplier calculation, the eligible loan amount rises accordingly, provided the co-applicant's own obligations don't offset the gain.

Q. Why did two different calculators give me two different numbers?

Because FOIR caps, income multipliers and assumed interest rates vary by lender and by calculator. The numbers in this guide are illustrative; your actual eligibility is confirmed only after a lender reviews your specific salary, obligations, property and credit profile.

Q. Does age affect eligibility even if my salary is strong?

Yes. Lenders cap the loan tenure so that repayment ends by a set retirement age, commonly around 60–65 for private-sector employees. A shorter allowable tenure raises the required EMI for the same loan amount, which can reduce eligibility even with a strong salary.

Final Thoughts

Home loan eligibility on salary comes down to three numbers working together — FOIR, the income multiplier, and LTV — with the lender applying the most conservative of the three. Knowing how each is calculated lets you estimate a realistic figure before you start house-hunting, and gives you concrete levers — clearing debt, adding a co-applicant, choosing tenure — to improve it.
