FOIR and DTI: How Indian Banks Decide Your Maximum Loan
FOIR is the share of your net monthly income already committed to EMIs and other fixed obligations. Indian lenders cap total EMIs at roughly 40–55% of net income, so your borrowing headroom is (net income × the lender’s cap) minus your existing EMIs — then converted into a principal at the offered rate and tenure.
Your loan size is almost never decided by what you ask for. It is decided by a single arithmetic constraint the lender applies before a human ever looks at your file.
Two applicants with identical ₹1,00,000 salaries can receive wildly different sanctions — one ₹18 lakh, the other a rejection. The difference is rarely the salary. It is what is already leaving the account each month, measured by a ratio called FOIR.
What FOIR actually measures
Fixed Obligation to Income Ratio is the proportion of your net monthly income consumed by fixed monthly commitments. Lenders use it as a solvency test: if too much of your income is already spoken for, an additional EMI is a risk regardless of how large the salary looks.
FOIR = (Total existing fixed monthly obligations + the proposed new EMI) ÷ Net monthly income, expressed as a percentage. Note that both the existing obligations and the new EMI sit in the numerator. This is the step most online explanations omit, and it is why people over-estimate what they qualify for.
- Counted as obligations: all existing loan EMIs, credit card minimum dues, rent in many lenders’ policies, alimony or maintenance, and any guaranteed loan where you are a co-signatory.
- Not counted: groceries, utilities, school fees, discretionary spending, or SIP contributions. These are variable, not fixed obligations.
- Net income means take-home after statutory deductions — not CTC. Using CTC is the single most common reason a self-calculated estimate comes in far above the sanction.
FOIR versus DTI: not the same ratio
Debt-to-Income is the term used in US and UK lending, and the two are frequently treated as synonyms. They are close but not identical, and the difference matters when you read international guidance and try to apply it in India.
| FOIR (India) | DTI (US/UK convention) | |
|---|---|---|
| Income basis | Net (take-home) monthly income | Usually gross monthly income |
| Rent treatment | Often included as a fixed obligation | Typically excluded from back-end DTI |
| Typical ceiling | 40–55%, lender and product dependent | 36–43% for conforming mortgages |
| Where it bites | Applied at underwriting as a hard cap | Applied as a guideline with compensating factors |
Because FOIR runs on net income while DTI usually runs on gross, an Indian 50% FOIR is a materially tighter constraint than a US 50% DTI on the same salary. Do not carry a threshold across from foreign guidance.
Calculating your actual borrowing headroom
The calculation runs in two stages. First find the rupee value of the EMI you can still support. Then convert that EMI into a principal, which is where the interest rate and tenure enter.
- Multiply net monthly income by the lender’s FOIR cap. That is your total permitted EMI outflow.
- Subtract every existing fixed obligation. The remainder is the EMI you can still service.
- Convert that EMI into a principal using the reducing-balance formula at the rate and tenure on offer.
Worked example: ₹1,00,000 net monthly income
- Net monthly income: ₹1,00,000. Lender FOIR cap: 50%. Permitted total EMI outflow: ₹50,000.
- Existing obligations: car loan EMI ₹18,000, plus an imputed ₹6,000 against a ₹1,20,000 credit card balance. Total: ₹24,000.
- Remaining EMI capacity: ₹50,000 − ₹24,000 = ₹26,000 per month.
- Convert to principal at 12% p.a. over 60 months. Monthly rate r = 0.01, n = 60. P = EMI × ((1+r)^n − 1) ÷ (r × (1+r)^n) = 26,000 × 44.955 ≈ ₹11,68,000.
Sanction ceiling ≈ ₹11.7 lakh — not the ₹22 lakh a naive "20× salary" rule of thumb would suggest. Clearing the credit card balance first would recover ₹6,000 of EMI capacity and lift the ceiling by roughly ₹2.7 lakh.
How to improve your FOIR before applying
- Close or pay down revolving credit card balances — this releases imputed obligations immediately and usually shows on the bureau within one cycle.
- Retire small, short-tenure loans. A ₹4,000 EMI with eight months left consumes the same headroom as one with five years left, but costs far less to clear.
- Add a co-applicant with income. Most lenders assess combined income against combined obligations, which can materially widen the cap.
- Declare all income sources — rental income, verified variable pay, and documented freelance receipts often count where the lender can evidence them.
- Avoid opening new credit lines in the three months before applying; each adds both an obligation and a hard enquiry.
Frequently asked questions
What is a good FOIR in India?
Below 40% is comfortable and typically attracts the best pricing. 40–50% is normal and approvable at most lenders. Above 55% is where declines cluster, though secured loans and high-income applicants are often assessed more leniently.
Does rent count in FOIR?
It depends on the lender. Many Indian lenders include rent as a fixed obligation, particularly for applicants in metros; others exclude it or count only a portion. Because policies differ, the same applicant can pass at one lender and fail at another on identical numbers.
Is FOIR calculated on gross or net salary?
Net — your take-home after provident fund, professional tax and TDS. Calculating on CTC or gross will substantially overstate what you can borrow, which is the most common reason a self-estimate exceeds the actual sanction.
How much personal loan can I get on a ₹50,000 salary?
With no existing EMIs and a 50% cap, you could service around ₹25,000 a month, which is roughly ₹11 lakh over five years at 12% p.a. Any existing EMI reduces that proportionally — a single ₹10,000 obligation cuts the ceiling to about ₹6.7 lakh.
Do credit cards affect FOIR if I pay in full every month?
Often yes. Many lenders impute an obligation of about 5% of the outstanding balance regardless of your repayment behaviour, because the bureau reports the balance rather than your intent. Paying down cards before applying is one of the fastest ways to increase a sanction.
Can I get a loan if my FOIR is above 60%?
It is difficult for unsecured lending. Options include adding a co-applicant, extending the tenure to reduce the proposed EMI, borrowing a smaller amount, or moving to a secured product such as a loan against property where lenders tolerate higher ratios.
