Loan Eligibility Calculator: How Much Can You Borrow?

Mohan Lal Saini owed his credit card exactly nothing. Zero. He had paid it in full every month for six years, mostly because his wife checked. The card sat in a drawer behind the ration card and the school ID.

It cost him about ₹22 lakh of home loan eligibility.

Mohan is 41, a government schoolteacher in Ajmer, and a composite — the numbers below are assembled from the pattern, not from one person’s file. He applied to two lenders in the same fortnight for the same flat off Jaipur Road, with the same salary slips, the same credit report and the same clean repayment history. One lender sanctioned around ₹31 lakh. The other stopped at roughly ₹8 lakh. Nothing about Mohan changed between the two applications. What changed was how each lender’s underwriting sheet treated a card he was not using.

The ratio that actually does the underwriting

Almost every explainer on loan eligibility describes a formula in which your income produces an EMI ceiling and the EMI ceiling produces a loan amount. That much is true and it is also the least interesting third of the process. The variable that decides Mohan’s outcome is the one in the middle, and it has a name most borrowers never hear: the Fixed Obligation to Income Ratio.

FOIR is the fraction of your income already committed to obligations the lender treats as unavoidable. Indian lenders typically want the new EMI plus all existing fixed obligations to sit somewhere in the 40 to 60 per cent band of assessed income, with the exact cap varying by lender, by income slab, by employment type and by product. A government schoolteacher with a pension-track job is usually assessed generously. Mohan’s lender used 50 per cent.

Here is the part that matters. The word “obligation” is not defined for you anywhere on the application form. It is defined inside each lender’s credit policy, and it is not the same document at every bank. Loan EMIs are in it everywhere. Rent is in it at many lenders. Insurance premiums appear at some. And a credit card enters the calculation through one of two entirely different doors.

The two doors a credit card can walk through

Door one: the lender pulls your credit information report, reads the current outstanding on the card, and treats the monthly minimum due on that outstanding as the obligation. Owe nothing, and the obligation is nothing. This is the treatment most borrowers assume is universal.

Door two: the lender ignores what you owe and looks at what you are permitted to owe. The sanctioned limit on the card is a live, drawable commitment. You can walk out of the branch after the home loan is disbursed and spend the entire limit that afternoon, and the lender has no ability to stop you. So the credit policy assigns a notional monthly obligation — a percentage of the sanctioned limit, applied whether or not a single rupee has been drawn.

Both doors are defensible. Door two is the one nobody warns you about, and it is not a fringe practice. The logic behind it is the same logic the Reserve Bank of India’s capital adequacy framework applies to banks themselves: an undrawn commitment is converted into a notional exposure through a credit conversion factor, because the bank cannot pretend an unused line will stay unused. A borrower’s unused card limit is treated as a contingent liability for the same reason a bank’s unused overdraft line is. The difference is that the bank knows this and the borrower does not.

The arithmetic, run all the way through

Mohan’s gross salary is around ₹78,000 a month. After the mandatory pension contribution, professional tax and TDS, the figure a lender assesses lands near ₹61,000. At a 50 per cent FOIR cap, ₹30,500 a month is the entire budget available for every fixed obligation including the new home loan.

He has a scooter loan with fourteen instalments left, at ₹3,200 a month. He also has a co-branded card carrying a ₹4,00,000 sanctioned limit, which the issuer raised twice over six years, each time framed as a reward for good conduct. Outstanding: zero.

At an indicative 8.75 per cent over 20 years, each ₹1 lakh of home loan costs roughly ₹884 a month in EMI. That conversion factor is the hinge everything else turns on.

Under door one, obligations are ₹3,200. Available EMI is ₹27,300, which at ₹884 per lakh supports about ₹30.9 lakh.

Under door two, with a notional five per cent of the sanctioned limit, the card alone contributes ₹20,000 of obligation. Add the scooter and ₹23,200 of Mohan’s ₹30,500 budget is gone before the home loan is considered. The residual ₹7,300 supports about ₹8.3 lakh.

Now the third line, which is the one worth remembering. Mohan phoned the card issuer and asked for the sanctioned limit to be brought down to ₹50,000. It took one call and there was no fee. Under the identical credit policy that had just produced ₹8.3 lakh, the notional obligation falls to ₹2,500, the residual EMI rises to ₹24,800, and the eligible principal recovers to roughly ₹28.1 lakh. About ₹19.8 lakh of borrowing capacity was restored by a request that cost nothing and changed no fact about his finances.

What nobody tells you about the limit ratchet

The reason this catches careful people specifically is that the sanctioned limit only ever moves in one direction unless you intervene. Card issuers raise limits as a retention and spending device, and the customers who get offered increases are precisely the ones who pay in full every month. Under the Reserve Bank of India’s Master Direction on credit card and debit card issuance and conduct, an issuer must obtain the cardholder’s express consent before enhancing a credit limit — but consent given as a single tap inside an app, on a screen that reads like a congratulation, does not register as a financial decision. Six years of that produced a ₹4,00,000 commitment Mohan had never used and could not have named.

The second thing nobody says: closing the card and reducing the limit are not the same action, and the wrong one hurts you. Closing removes the account’s payment history and its contribution to your total available credit, which can lift your reported utilisation ratio on the cards that remain and shorten your average account age. Reducing the sanctioned limit on a card you keep open leaves the history intact and shrinks only the contingent exposure. If you have three cards and two are dormant, reducing limits across all three beats closing any of them.

Third: the same treatment applies to overdraft facilities, sanctioned-but-undrawn top-up lines on an existing loan, and any revolving facility linked to your name. An approved but untouched overdraft on a current account can behave in an underwriting sheet exactly the way Mohan’s card did.

What to actually do, in the order that works

Pull your own credit information report first, not the lender’s version of it. You are entitled to a free full report from each credit information company each year. Read the sanctioned limit column, not the balance column. That column is the one being converted into an obligation.

Total every revolving limit in your name. Cards, overdrafts, undrawn top-ups, consumer-durable lines opened at a shop counter and forgotten. Multiply the total by five per cent. If that figure is a serious fraction of your monthly income, you have found your eligibility problem before the lender does.

Reduce limits, do not close accounts — and do it at least one full reporting cycle before you apply, so the revised limit appears in the report the lender pulls. A reduction requested the week of the application will not show up in time to help.

Ask the credit manager the question directly. “Does your policy treat an unused card limit as a fixed obligation, and at what percentage?” Sales staff often do not know. Credit staff always do. Asking it before you pay a processing fee is free; asking it after is expensive.

Do the tenure arithmetic separately. Stretching tenure raises eligibility because it lowers EMI, which is why it is the first lever a sales desk offers. It is also the lever that costs the most interest. Fix the obligations problem first, and only then decide how long you want to be paying.

What this does not mean

It does not mean every lender applies a notional charge on unused limits. Many read the outstanding balance and nothing else, which is exactly why Mohan’s two sanction letters disagreed so violently. The point is not that door two is standard — it is that you cannot tell which door you are walking through from anything printed on the application form, and the difference can be an entire flat.

It does not mean credit cards damage your borrowing capacity. A card used and repaid builds precisely the repayment record that gets you priced well. It is the idle, inflated limit that costs you, not the card.

And it emphatically does not mean you should chase the largest sanction available. Eligibility is the lender’s statement about its own risk appetite, not a statement about what your household survives. Mohan’s recovered ₹28.1 lakh was useful because the flat cost ₹34 lakh and he had savings; it would have been a trap if he had treated it as a target. Decide the EMI you could still pay if the rate rose two points and one income paused, then let that decide the loan. The gap between what a bank will lend and what you should borrow is the only cushion your family actually has.

Frequently asked questions

Does reducing my credit card limit lower my credit score?

It can nudge it, because a lower total limit raises your utilisation ratio if you carry any balance at all. If you clear the card in full each month your reported utilisation stays near zero either way, and the effect is negligible. Closing the account outright is the more damaging move, because it removes the account’s age and payment history from the calculation entirely. Reduce, keep open, keep using it lightly.

How far in advance should I reduce limits before applying?

Allow at least one full reporting cycle, and ideally two. Card issuers report to credit information companies on a periodic cycle, and the lender underwrites the report as it stands on the day it is pulled. A limit reduced after the report is generated is invisible to the credit manager, however genuine it is.

Do lenders count rent as a fixed obligation too?

Many do, particularly for salaried applicants who will continue renting after the loan, and some apply it only where the rent is documented. Like the card treatment, it lives in each lender’s internal credit policy rather than in any published rule, so the only reliable way to know is to ask the credit desk what enters their obligation line.

Does a co-applicant fix an obligations problem?

It raises assessed income, which raises the rupee value of the FOIR budget, so it can absorb the problem without solving it. But the co-applicant’s own cards and limits enter the same calculation, so a spouse with two high-limit cards can add less capacity than expected. Clean up both sides before combining them.

Is the notional percentage on unused limits always five per cent?

No. Five per cent is a common working assumption because it approximates a typical minimum-due formula, but the figure varies by lender and by product, and some policies apply it only above a threshold limit. Treat five per cent as a planning estimate for your own arithmetic, and get the actual figure from the lender you intend to apply to.

Regulatory background: the Reserve Bank of India’s Master Direction on Credit Card and Debit Card issuance and conduct governs credit limit enhancement and the express consent required for it, and requires issuers to disclose that repayment information is furnished to credit information companies under the Credit Information Companies (Regulation) Act, 2005. The treatment of undrawn commitments as notional exposure through a credit conversion factor comes from the RBI’s capital adequacy framework for banks. FOIR itself is not a published regulation but a credit-policy convention; the three-scenario reconstruction, the ₹884-per-lakh conversion, the limit-reduction arithmetic and the character of Mohan Lal Saini are this article’s own.
