FOIR is not a regulation and not a verdict. It is one division. Add up the fixed repayments that leave the account every month, divide by monthly take-home, and that is the whole of it. Everything contested about the ratio sits in the second step, which is what a lender then chooses to do with the answer.
What the ratio measures #
FOIR stands for the fixed obligation to income ratio. A lender totals the instalments already committed each month, which usually means a running home loan, a car loan, a personal loan and the minimum due on a credit card, then expresses that total as a share of monthly income. Some lenders use net take-home and others use gross salary, which on the same payslip produces two different ratios before anyone has made a decision about anything.
The purpose is narrow and reasonable. A lender is trying to estimate how much of an income is already promised elsewhere before promising more of it. The ratio is a screening arithmetic, not a measure of financial health, and it was never designed to be one.
The rule that is not there #
Search for a FOIR limit in India and the answer comes back with unusual confidence. Forty percent. Fifty percent. Fifty five for higher incomes. The figures are often stated flatly, sometimes alongside the letters RBI, but the source and scope matter.
The current source for commercial banks is the Reserve Bank of India (Commercial Banks – Credit Facilities) Directions, 2025, issued on 28 November 2025 and updated on 15 July 2026. Chapter VIII now consolidates the housing-finance rules. The older 1 April 2025 Master Circular on Housing Finance is watermarked withdrawn on RBI's site; RBI's consolidation notice says the new directions repealed the earlier credit-facility instructions.
We read Chapter VIII, paragraphs 88 to 124, on 16 August 2026 with the absence as the specific question. That chapter covers bank policy, eligible and excluded housing finance, intermediary agencies, loan quantum, upfront disbursal, disclosures, priority-sector treatment, pricing and fair-lending cross-references. We also searched the current direction for FOIR and related income-to-instalment terms.
There is no FOIR or income-to-instalment cap in that housing-finance chapter. This is deliberately narrow: it is a finding about the current commercial-bank credit-facilities instrument, not a claim that every RBI direction for every lender contains no repayment-capacity rule.
The direction does set hard ceilings, and it is worth naming them so the absence is not mistaken for an absence of regulation altogether. Paragraph 111 sets loan-to-value ratios, which limit the share of property value that may be lent: up to 90 percent for individual housing loans up to Rs 30 lakh, 80 percent above that up to Rs 75 lakh and 75 percent beyond. Those are regulatory limits against the asset. The housing chapter does not set a matching percentage against income.
Who actually sets the number #
Lender-published examples show why one band should not be mistaken for a shared rule. Bajaj Finance's home-loan FOIR explainer says maximum thresholds are usually around 40 to 50 percent and explicitly says lenders vary. Kotak's personal-loan guide publishes a 50 to 60 percent band. These are educational pages, not promises of approval, but they are direct evidence that the number can differ by lender and product.
This matters more than it first sounds. A convention presented as a regulation looks like a legal wall. A lender criterion can instead vary with the product and borrower profile. A rejection at one lender does not establish an RBI prohibition, though another lender may still decline for its own underwriting reasons.
The arithmetic, worked #
Take a monthly take-home of Rs 1,20,000 with two commitments running, a car loan instalment of Rs 18,000 and a personal loan instalment of Rs 12,000. Fixed obligations come to Rs 30,000. Divided by Rs 1,20,000 that is a ratio of 25 percent.
Now hold the same payslip and change nothing except the rent, which is Rs 45,000. The ratio does not move at all, because rent is not an instalment. It stays at 25 percent. Meanwhile the money genuinely committed each month before any discretionary spending has gone from Rs 30,000 to Rs 75,000, which is 62.5 percent of take-home.
Both numbers are arithmetically correct and they describe the same household. That gap is the single most useful thing to understand about the ratio, and it is why a comfortable FOIR and a stretched month are not remotely contradictory.
The budget tool computes this ratio from figures entered on the page, alongside what the repayments take out of the needs band and what is left in that band once rent is out too. It divides and reports. It sets no limit and reads no verdict off the result.
What the ratio leaves out #
Rent, as above, and it is the largest single exclusion for most salaried renters. School fees, which are as fixed as any instalment and often larger. Insurance premiums, whether paid monthly, quarterly or annually. Support sent to parents, which for a great many Indian households is the most reliably fixed obligation of all and appears on no statement as a loan.
None of that is a flaw in the ratio so much as a limit on what one division can carry. The error is reading a screening arithmetic as a judgement about whether a household can afford something. It was built to answer a lender's question, which is how much of this income is already pledged to other lenders, and it answers that question well. It was not built to answer the household's question, and it does not.

Sources. The housing-finance scope, loan-to-value slabs and scoped absence finding come from the RBI (Commercial Banks – Credit Facilities) Directions, 2025, RBI/DOR/2025-26/154, DOR.CRE.REC.73/07-01-001/2025-26, issued 28 November 2025 and updated 15 July 2026. RBI's consolidation and withdrawal circular records that the new directions repealed earlier credit-facility instructions; the old 1 April 2025 housing circular is visibly watermarked withdrawn. The 40 to 50 percent example comes from Bajaj Finance's home-loan FOIR explainer, dated 17 March 2026, and the contrasting 50 to 60 percent example from Kotak Mahindra Bank's personal-loan guide, dated 13 April 2026. These lender pages are examples, not universal underwriting commitments. Regulatory and lender sources were checked 16 August 2026. Worked figures are illustrative arithmetic, not sourced averages.

Does the RBI set a FOIR limit?
Not in the current Reserve Bank of India (Commercial Banks – Credit Facilities) Directions, 2025, updated on 15 July 2026. Its housing-finance chapter sets loan-to-value and risk-weight rules but no FOIR or income-to-instalment cap. This is a scoped finding about that instrument for commercial banks, not a claim about every RBI rule or every kind of lender.
Where does the 40 to 50 percent figure come from?
It appears in lender-published guidance, not as an RBI ceiling. Bajaj Finance's home-loan explainer describes maximum FOIR thresholds as usually around 40 to 50 percent and says lenders vary; Kotak's personal-loan guide publishes 50 to 60 percent. These are examples, not universal promises: the lender, product and borrower profile can change the number.
Which repayments count in the ratio?
Fixed obligations, which is what the F in FOIR stands for. A home loan instalment, a car loan, a personal loan and the minimum due on a card are the usual ones. Rent is not an instalment and is generally excluded, which is a large part of why the ratio can look comfortable for a household whose money is in fact already committed.
Is a lower ratio always better?
The ratio measures one thing only, which is the share of income already promised to fixed repayments. It says nothing about what is left after rent, groceries, school fees and premiums, because none of those are instalments. A low ratio alongside a high rent is a common and misleading combination.
