How This Is Calculated

FOIR (Fixed Obligations to Income Ratio) measures what percentage of your gross income goes toward fixed monthly obligations — all EMIs and recurring debt payments combined. Lenders typically use FOIR (commonly capped around 40-50%) to assess how much additional loan a borrower can safely take on; a lower FOIR indicates more room for new borrowing.

Frequently Asked Questions

What is a healthy FOIR percentage? ▼
Most lenders cap FOIR around 40-50% of gross income for loan approval, but a more conservative personal target — well below the bank's maximum — leaves more room for savings, emergencies and other goals rather than being fully stretched on debt.
Does FOIR include rent as a fixed obligation? ▼
Lenders typically calculate FOIR based on EMI/debt obligations rather than rent, but from a personal budgeting perspective, it's worth including rent (or any recurring housing cost) when assessing your own true fixed-obligation burden, even if a bank's FOIR calculation doesn't.
How is FOIR different from a credit score? ▼
FOIR measures your current debt burden relative to income (a cash-flow capacity metric), while a credit score reflects your repayment history and credit behavior over time. Lenders typically use both together — a good credit score with a high FOIR can still lead to loan rejection or reduced eligibility.

Methodology, assumptions and sources

Scope: Computes the Debt-to-Income (DTI) ratio and FOIR (Fixed Obligation to Income Ratio) commonly used by Indian lenders to assess loan eligibility.

Calculation logic

  1. DTI = (Total monthly debt obligations ÷ Gross monthly income) × 100.
  2. FOIR = (Total fixed monthly obligations, including the proposed new EMI, ÷ Net/gross monthly income, per the lender's convention) × 100.
  3. Compare the computed ratio against commonly used lender thresholds (typically 40–50% FOIR) to indicate likely eligibility headroom.
