A couple in Bengaluru with a healthy combined salary walked into a bank expecting to be offered the flat of their dreams, and were surprised when the sanction came in well below what they had assumed their income could support. The reason was not their salary, it was the car loan and two credit card balances quietly eating into their monthly capacity. Lenders do not lend against your income alone, they lend against what is left after your existing commitments, and the ratio they use to measure that is the single biggest driver of how much you can borrow.

The short answer. Your home loan eligibility is largely decided by your fixed obligations to income ratio, or FOIR, which is the share of your monthly income already committed to fixed obligations such as existing loan instalments. Lenders usually want your total obligations, including the new home loan instalment, to stay within a comfortable band of your income, often in the region of 40 to 55 percent. The trade off to understand is that reducing existing commitments, or spreading the loan over a longer tenure, raises how much you can borrow, but the goal is a repayment you can actually sustain rather than the largest possible number.

What is FOIR?

FOIR stands for fixed obligations to income ratio, and it measures how much of your monthly income is already tied up in fixed commitments. To calculate it, a lender adds up your regular fixed outgoings, most importantly the instalments on your existing loans, and expresses that total as a percentage of your net monthly income. The higher that percentage, the less of your income is free to service a new loan.

Lenders rely on it because it answers the question that matters most to them: after everything you are already committed to paying, how much room is left for a home loan instalment? Two people on the same salary can have very different borrowing capacity if one is debt free and the other is carrying several loans, and FOIR is the tool that captures that difference in a single number.

It also explains a common surprise. Buyers often estimate their budget from their gross salary and are then puzzled when the sanctioned amount comes in lower, because they had not accounted for the loans, cards and other commitments the lender can see. FOIR is not the bank being difficult, it is the bank applying the same test a careful borrower should apply to themselves: not what you earn, but what you can comfortably spare each month after your existing promises are kept.

How does FOIR decide your loan amount?

It works through a simple ceiling. A lender decides the maximum share of your income it is willing to see committed to all obligations together, then subtracts your existing fixed commitments, and what remains is the room available for your new home loan instalment. From that permissible instalment, and the interest rate and tenure, the lender works backwards to the loan amount it can offer.

This is why the relationship between FOIR and the loan amount is an inverse one. The more of your income that is already spoken for, the smaller the instalment the lender will allow for the new loan, and therefore the smaller the loan. A borrower with few existing commitments has more of that permissible band free, and can support a larger home loan on the same income than a peer weighed down by other debts.

What counts as a fixed obligation?

Fixed obligations are the regular, committed payments that reduce the income available for a new loan. The clearest examples are the instalments on your existing loans, such as a car loan, a personal loan or another home loan. Depending on the lender's policy, other recurring commitments may also be counted, and lenders assess these against your net income after statutory deductions.

A detail worth knowing is that even undrawn credit can weigh on the assessment. A large outstanding balance on a credit card is treated as an obligation, and some lenders take a cautious view of high available limits too, since they represent debt you could take on at any time. Clearing card balances before you apply therefore does double duty, it lifts your credit score and it lightens the obligations side of the ratio, both of which push your eligibility in the right direction.

Read the table as a set of levers: some, like your income, set the base, while others, like existing EMIs and tenure, you can actively adjust to change how much you can borrow.

What income does the lender actually count?

The income side of the ratio is your net income after statutory deductions, not the headline figure on your offer letter, so it is worth knowing what a lender will and will not count. A stable, documented salary is the strongest input, and lenders read it from your salary slips and bank statements rather than from what you tell them. Variable income such as bonuses, incentives or overtime is treated more cautiously, often counted only in part or averaged over time, because it is not guaranteed month to month.

Other income can help if you can prove it. Documented rental income, income from a second earner added as a co-applicant, and other steady, verifiable receipts can widen the income base the lender works from. The common thread is documentation: income that shows up cleanly in your statements and returns counts for far more than income you simply assert, which is why organising your paperwork before you apply is part of maximising eligibility.

How can you improve your eligibility?

The most direct lever is reducing your existing fixed obligations before you apply. Closing or prepaying a small loan, or clearing high credit card balances, frees up part of your income and immediately increases the instalment a lender will allow for your home loan. Because the effect is on the ratio, even modest reductions in existing commitments can meaningfully raise your eligibility.

A longer tenure is another lever, since it lowers the monthly instalment for a given loan amount, which fits more loan under the same permissible band. Adding an earning co-applicant raises the income side of the ratio and can lift eligibility further. Each of these has trade offs, a longer tenure means more total interest and a co-applicant shares the liability, so use them deliberately rather than simply to maximise the number.

Why the largest loan is not always the right one?

Because the lender's ceiling is a maximum, not a recommendation. A bank willing to let your obligations reach the top of its permissible band is telling you what it will allow, not what will leave you comfortable. Borrowing right up to that limit can make your monthly life fragile, with little cushion for a rate rise, a job change or an emergency, all of which are real over the long life of a home loan.

A sensible buyer treats FOIR as a guardrail and then sits comfortably inside it. Work out the instalment you can pay without strain, keeping room for savings and unexpected costs, and borrow to that figure rather than to the lender's maximum. This is buyer guidance on how eligibility is assessed, not advice on how much you personally should borrow, which depends on your income stability, your other goals and your comfort with debt.

A seven step home loan eligibility checklist

1. List your existing fixed obligations, especially the instalments on current loans.
2. Work out your net monthly income after statutory deductions.
3. Estimate how much of your income lenders will allow across all obligations together.
4. Reduce or close small loans and high card balances before you apply.
5. Consider a tenure that keeps the instalment comfortable rather than the shortest possible.
6. Add an earning co-applicant if you need to lift the income base.
7. Choose a loan you can service comfortably, not the maximum the lender allows.

Approaching a lender with your obligations trimmed and your income neatly documented puts you in the strongest position, and it often turns a borderline sanction into a comfortable one.

What is FOIR in a home loan?

FOIR, or fixed obligations to income ratio, is the share of your monthly income already committed to fixed outgoings such as existing loan instalments. Lenders use it to judge how much room is left for a new home loan instalment. A higher FOIR means less room and a smaller loan, while a lower FOIR supports a larger one.

What FOIR do lenders usually accept?

Lenders generally want your total obligations, including the new home loan instalment, to stay within a comfortable band of your income, often in the region of 40 to 55 percent, though the exact figure varies by lender and profile. Staying within that band is what leaves enough disposable income to service the loan without strain.

How can I increase my home loan eligibility?

Reduce your existing fixed obligations by closing or prepaying small loans and clearing high card balances, which frees up income for the new instalment. You can also choose a longer tenure to lower the monthly instalment, or add an earning co-applicant to raise the income base. Each has trade offs, so use them deliberately.

Should I borrow the maximum the lender offers?

Not necessarily. The lender's ceiling is a maximum, not a recommendation, and borrowing right up to it can leave little cushion for a rate rise or an emergency. Work out the instalment you can pay comfortably while still saving, and borrow to that figure rather than to the maximum the lender is willing to allow.
