What FOIR actually is
FOIR stands for Fixed Obligation to Income Ratio. It’s the percentage of your monthly income that’s already committed to fixed payments - existing EMIs, credit card minimums, any other recurring debt obligation - before a new loan is even added to the picture. Lenders calculate it as: (Existing EMIs + proposed new EMI) ÷ Monthly income × 100.
Most banks and NBFCs in India cap this somewhere between 40% and 60%, depending on your income bracket and credit profile. Higher earners are often allowed a higher FOIR ceiling, on the theory that a larger absolute income leaves more breathing room even at a higher percentage commitment.
Why two people with the same salary can get different offers
This is the part that surprises most first-time borrowers. Income alone doesn’t determine your loan eligibility - what’s already committed against that income does. Someone earning ₹80,000 a month with no existing EMIs has far more room under a 50% FOIR cap than someone earning the same amount who’s already paying ₹25,000 toward a car loan and a personal loan. The second applicant isn’t being penalized for poor judgment; they simply have less room left under the same ratio.
What this means practically
A few things follow directly from how FOIR works, and none of them require guessing. Paying down or closing an existing loan before applying for a new one directly increases how much room you have under the cap - this is arithmetic, not advice, and it’s one of the few loan-eligibility factors a borrower can actually move in the short term.
A co-applicant’s income can raise the combined ceiling, but their existing obligations get added to the combined numerator too - it only helps if their own debt load is genuinely low.
Lenders vary in where exactly they set the FOIR cap, and in whether they apply it strictly or use it as one input among several - this isn’t a single fixed number across the industry, which is part of why shopping the same loan request across multiple lenders can produce meaningfully different offers.
