Lenders do not ask how much you want - they calculate how much you can reliably repay. The rule is simple: take your income, reserve the share a bank allows for debt, subtract what you already owe, and convert the remaining monthly capacity into a loan amount at your rate and tenure.
Home Loan Eligibility Calculator does exactly that in reverse. Enter your net monthly income, existing EMIs, the loan tenure, interest rate, your age and a credit profile, and it returns the maximum loan you can expect to qualify for - along with the EMI it implies, your FOIR/DTI ratios and how tenure changes the answer.
Focus on the borrowing ceiling rather than the monthly bill: slide the tenure and existing-EMI inputs to see how much headroom each decision buys you. Everything runs in the browser; nothing is uploaded.
