How lenders decide what you can borrow

Eligibility is not a judgement about you. It is an arithmetic ceiling derived from your income minus your existing obligations — and one of those obligations may be a credit card you never use, counted against you at a fraction of a limit you never asked to be raised.

Two ceilings, and the lower one wins

Every secured loan is capped twice, and you get the smaller of the two.

CeilingBased onQuestion it answers
Repayment capacityYour income, less existing obligationsCan this person service the EMI?
Asset valueLoan-to-value cap on the property or collateralCan the lender recover if they cannot?

For an unsecured loan there is no second ceiling, which is precisely why the rate is higher — nothing backs it but the first.

People usually assume the binding constraint is income. Frequently it is not. It is income minus obligations, and the obligations side is where eligibility is unexpectedly lost.

FOIR: the number that actually decides

Lenders work with a fixed obligation to income ratio — the share of monthly income already committed to fixed payments. The proposed new EMI is added, and the total must stay within a threshold the lender sets.

Broadly: (existing EMIs + proposed EMI) ÷ monthly income, and the threshold is typically somewhere between a third and a half, varying by lender, income level and loan type. Higher incomes are often allowed a higher ratio, on the reasoning that what remains in rupees is still adequate.

Two consequences follow, and the second is the useful one.

Every existing EMI reduces your ceiling by roughly its own size, multiplied up. If the threshold is 50%, a ₹10,000 car loan EMI removes ₹10,000 of monthly capacity — which at typical home loan tenures translates into several lakh of borrowing capacity, not ₹10,000.

Clearing a small loan before applying can raise eligibility by far more than the loan's outstanding balance. That is the single highest-leverage action available before a home loan application, and it is arithmetic rather than a favour.

The unused limit that counts against you

Here is the part almost nobody knows.

Many lenders count a notional obligation against your credit card limits — a small percentage of the total limit available to you — regardless of whether you use the cards or clear them in full every month.

The logic is defensible from the lender's side: an available limit is money you could draw tomorrow, and the assessment is about capacity rather than current behaviour.

The effect on you is not intuitive. Someone with several cards, high limits and a zero balance can have materially lower home loan eligibility than someone with one modest card — despite better behaviour and an identical income.

Two responses, and they conflict with other advice in ways worth being explicit about. Reducing or surrendering limits before a large application can raise eligibility. But closing old cards shortens credit history and raises reported utilisation, both of which can lower your score.

The resolution is sequencing: reduce limits rather than close accounts, and do it a few months before applying so bureau records update. Whether this is practice or requirement varies by lender — it is worth asking directly how they treat unused limits, because the answer changes what you should do.

What counts as income

Less than you might expect, and the definition is where self-employed applicants most often lose ground.

Also relevant: employment stability and age. A short tenure at a current employer or frequent job changes reduce comfort, and age caps the tenure — a loan generally cannot run far past expected retirement, and a shorter tenure means a higher EMI and therefore a lower eligible amount.

Where the credit score fits

Score and eligibility are related and are not the same thing.

The score is mostly a gate and a price. Below a lender's cut-off you may be declined outright; above it, a better score generally earns a lower rate. It does not usually increase the amount, because the amount is set by FOIR and by asset value.

The exception is worth knowing: a lower rate produces a lower EMI for the same amount, which frees FOIR headroom — so a good score can raise eligibility indirectly.

One practical caution. Several loan applications in a short window read as distress and each leaves a hard enquiry. Compare offers by asking for indicative terms rather than submitting full applications everywhere.

Raising eligibility, in order of effect

  1. Clear a small existing loan. Removes an EMI from FOIR and typically buys back several times its outstanding balance in capacity.
  2. Add a co-applicant with income. The largest single lever, with a real liability attached.
  3. Reduce unused credit card limits, a few months ahead, without closing the accounts.
  4. Extend the tenure. Lowers the EMI and raises the eligible amount — and costs substantially more in total interest. This is a real trade, not a free win.
  5. Improve the score before applying, which affects the rate and indirectly the amount.
  6. Increase the down payment, which reduces the loan needed rather than raising what you can get.

Eligible is not the same as affordable

The most important sentence in this article.

Lender thresholds are set to protect the lender's recovery, not your resilience. A FOIR of 50% means half your income is committed before you have eaten — and it is a ceiling the lender is comfortable with because they hold the asset, not because it is comfortable for you.

The stress test from good debt versus bad debt applies directly: recompute the ratio against a meaningfully lower income — one salary instead of two, or a freelance year at 70%. If the payments no longer work, the loan is too large regardless of what you were approved for.

Borrowing the maximum eligible amount is a decision, and it is one made by very few people deliberately.

Working out what you should borrow

Eligibility is the lender's number. The one that matters to you is what the EMI leaves intact.

A useful check: after the proposed EMI, is there still enough to fund the emergency fund, the sinking fund, and the monthly investment the goals require? FNOTrader's Mutual Funds app runs that remaining contribution against real NAV history — around 34 million NAV rows — reporting XIRR and final value, so the cost of the larger loan shows up as a smaller corpus rather than as an abstraction.

FNOTrader is not a lender and does not recommend credit products.

Common questions

How do lenders calculate loan eligibility?

Through two ceilings, and you get the lower one: repayment capacity based on income less existing obligations, and for secured loans a loan-to-value cap on the asset. The binding constraint is usually obligations rather than income.

What is FOIR?

Fixed obligation to income ratio — the share of monthly income already committed to fixed payments, with the proposed EMI added. Lenders cap it, typically somewhere between a third and a half depending on lender, income level and loan type.

Can an unused credit card reduce my loan eligibility?

Often yes. Many lenders count a notional obligation against your total credit card limits regardless of usage, since an available limit is money you could draw tomorrow. Someone with several high-limit cards and a zero balance can have lower eligibility than someone with one modest card.

Should I close my credit cards before applying for a home loan?

Reduce limits rather than close accounts, and do it a few months ahead so bureau records update. Closing old cards shortens credit history and raises reported utilisation, both of which can lower your score — so the two pieces of advice conflict unless you sequence them.

Why do self-employed applicants get lower eligibility?

Because income is usually taken as profit declared in filed returns, averaged over several years. Income minimised for tax is income minimised for eligibility, and the two objectives pull in opposite directions.

Does a good credit score increase how much I can borrow?

Mostly it acts as a gate and a price rather than an amount. But a better score earns a lower rate, a lower rate means a lower EMI for the same loan, and that frees FOIR headroom — so it raises eligibility indirectly.

What is the fastest way to increase eligibility?

Clearing a small existing loan, which removes an EMI from FOIR and typically buys back several times its outstanding balance in borrowing capacity. Adding a co-applicant with income is the largest lever, though it creates a real joint liability.

Does being approved mean I can afford it?

No. Lender thresholds protect the lender's recovery, not your resilience — a 50% FOIR means half your income is committed before you have eaten. Recompute against a meaningfully lower income, and if the payments fail, the loan is too large regardless of approval.
