Find the maximum home loan you are eligible for - using the FOIR method that Indian banks actually apply when sanctioning loans.
FOIR = (All Monthly EMIs ÷ Net Income) × 100. Banks set a ceiling - typically 40–50% - to ensure you have enough income left for living expenses after all loan repayments.
Adding a co-applicant (spouse or earning parent) combines both incomes for FOIR calculation, directly increasing the maximum loan amount - often by 40–80%.
Extending tenure from 15 to 30 years reduces the EMI on the same loan by ~33%, increasing your eligible loan amount significantly - at the cost of more total interest.
