How Much Home Loan Can You Afford? A Practical Guide for Indian Homebuyers

Before you walk into a bank, before you shortlist a project, before you even decide which city to buy in, there is one number worth knowing: how much home loan can you actually afford? Not how much a bank is willing to lend you, which is a different question, but how much you can borrow without turning your finances into a permanent stress test. These two figures are often very different. And the gap between them is where many Indian homebuyers make the most expensive mistake of their lives.

When a lender evaluates your home loan eligibility, it applies a framework called FOIR, which stands for Fixed Obligation to Income Ratio. This measures the share of your monthly gross income already committed to fixed payments including existing EMIs and the proposed home loan EMI combined. Most Indian banks and housing finance companies approve loans where the total FOIR stays between 40 and 55 percent of gross monthly income. Some lenders go up to 55 percent for strong credit profiles.

That ceiling is what determines how much the bank will lend you. But it is not the ceiling you should use when deciding how much you want to borrow. The bank's 50 percent FOIR is the maximum it is comfortable with as a lender. Your comfort zone as a borrower should ideally sit at 40 percent or below, leaving meaningful room for monthly savings, emergency expenses, children's education costs, and the kind of lifestyle disruptions that no calculator accounts for in advance.

The rule is simple. Your total monthly EMI commitments across all loans, including the new home loan, should not exceed 40 percent of your take-home salary. Take-home here means what actually hits your bank account after tax deductions, provident fund contributions, and any other payroll deductions.

Here is how it works in practice. If your monthly take-home salary is ₹60,000 and you currently have no other loan obligations, your maximum affordable EMI is approximately ₹24,000. At current home loan interest rates of around 8 to 8.5 percent per annum, a monthly EMI of ₹24,000 over a 20-year tenure supports a loan amount of roughly ₹28 to ₹32 lakh. At ₹1 lakh take-home with no existing EMIs, the same 40 percent rule gives you an affordable EMI of ₹40,000, which can support a loan of approximately ₹48 to ₹55 lakh over 20 years.

If you already carry existing obligations, say a car loan EMI of ₹8,000 per month, that amount reduces your available capacity for a home loan EMI by exactly the same figure. On a ₹60,000 take-home salary, your safe home loan EMI drops from ₹24,000 to ₹16,000, and the supportable loan amount falls accordingly.

Your affordability is not just about the EMI. The total property cost you can realistically pursue depends on two things working together: the home loan amount you can sustain and the down payment you can arrange upfront. Indian banking regulations under RBI guidelines set the Loan-to-Value ratio, which determines how much of the property cost a bank will finance. For properties priced up to ₹30 lakh, banks can fund up to 90 percent. For properties between ₹30 lakh and ₹75 lakh, the cap is 80 percent. For properties above ₹75 lakh, it drops to 75 percent.

This means that for a ₹50 lakh property, the bank funds up to ₹40 lakh and you must arrange ₹10 lakh yourself. For a ₹1 crore property, you need at least ₹25 lakh as down payment. Affordability calculators used by banks like ICICI consider your down payment, gross monthly income, existing EMIs, interest rate, and loan tenure together to arrive at the total property cost you can pursue.

Adding a co-applicant, typically a working spouse or an earning parent, is the most effective single step you can take. Banks consider the combined income of all applicants, which can increase your eligible home loan amount by 50 to 80 percent. A CIBIL score above 750 also earns better interest rates, which means lower EMIs for the same loan amount. Clearing small existing loans before applying, such as a personal loan or a two-wheeler EMI, directly reduces your FOIR and creates more room for a larger home loan EMI.

Choosing a longer tenure reduces the monthly EMI and improves eligibility, though the total interest paid over the loan's life increases. Most borrowers who take 20 or 25-year loans end up closing them earlier through prepayment as their income grows. Indian home loans on floating rates have no prepayment penalty, so a longer tenure at the time of application does not lock you in permanently.

A final point that every first-time home loan applicant should carry into any bank discussion: the loan amount the bank approves and the loan amount that is genuinely comfortable for you are not the same thing. Banks underwrite loans against risk. You have to live inside the EMI every month for years. The 40 percent income rule is not a conservative fantasy. It is a practical boundary that leaves your financial life room to breathe.

Knowing how much home loan you can afford requires applying the 40 percent FOIR rule to your take-home salary, accounting for existing EMI obligations, understanding the down payment requirement based on property price, and verifying your CIBIL score before approaching any lender. Use an affordability calculator to simulate different combinations of loan amount, tenure, and interest rate before committing. What the bank offers and what you should borrow are two different numbers, and your long-term financial wellbeing depends on acting on the right one.
