Home Loan Eligibility & FOIR Explained

Published July 17, 2026By Samson PG

Quick answer

FOIR caps how much of your income can go to EMIs. Eligibility sketches multiply affordable EMI into a loan size — not a sanction letter.

Home Loan Eligibility

FOIR (Fixed Obligation to Income Ratio) is a lender-style lens: existing EMIs plus the new home-loan EMI should stay under a share of monthly income (often discussed in bands like ~40–50%, varying by policy).

Not lending or financial advice — illustrative only. Banks use credit score, LTV, property, and internal policy beyond FOIR.

FOIR sketch

FOIR ≈ (existing EMIs + proposed EMI) / net monthly income

If max FOIR is 50% and income is ₹100,000 with ₹10,000 existing EMIs, room for new EMI ≈ ₹40,000 before other constraints.

From EMI room to loan size

Given affordable EMI, rate, and tenure, invert the EMI formula to estimate principal — the same family as EMI amortization.

Input	Role
Income	Sets FOIR ceiling
Existing obligations	Reduce headroom
Rate & tenure	Map EMI ↔ principal
Down payment / LTV	Caps loan vs property value

What eligibility calculators omit

Employment stability, bureau score, co-applicant income treatment, and property technicals often dominate the real decision.

Why existing EMIs cost you more than their face value

FOIR counts your total monthly obligations, not just the new loan. So an existing EMI does not simply subtract from your budget — it subtracts from the room the lender is willing to give you, and that room is a fraction of income.

Working from an illustrative 50% FOIR on a ₹1,00,000 monthly income:

Existing EMIs	Room left for a new EMI
₹0	₹50,000
₹10,000	₹40,000
₹20,000	₹30,000
₹30,000	₹20,000

Each ₹10,000 of existing EMI removes ₹10,000 of capacity — which, at typical home-loan rates and tenures, can translate into several lakh less principal. Closing a small personal loan or vehicle EMI before applying often lifts eligibility more than an equivalent salary increase would.

Note that credit-card balances are usually treated differently from EMIs, but a card carrying a large revolving balance still affects the assessment through your credit profile.

What counts as income is narrower than you think

Lenders generally work from stable, documented income rather than everything that lands in your account. Variable pay — bonus, incentive, overtime — is often taken at a discounted rate or averaged over prior years, and some components may be excluded entirely. Rental income typically counts only partially.

For self-employed applicants the basis is usually declared profit after deductions over several years, which is frequently well below gross receipts. This is the most common reason a self-employed applicant’s own estimate exceeds the sanctioned figure by a wide margin.

Eligibility is not the same as sanction

Two further limits sit on top of FOIR, and the lowest of the three governs:

Loan-to-value. Lenders finance a percentage of the property value, not all of it, so your down payment caps the loan regardless of income.
Age and tenure. The tenure usually has to end by a retirement-age threshold, and a shorter tenure raises the EMI, which feeds back into FOIR.
Credit history. A weak score can reduce the offered amount, raise the rate, or decline the application outright, irrespective of comfortable ratios.

An eligibility figure is therefore an indicative ceiling for planning — the sanction letter is the number that exists. Treat any calculator output, including this site’s, as a starting estimate and confirm with the lender before committing to a property.
