The bank's loan eligibility number and the loan you should actually take are two different things. Banks calculate maximum eligibility — the most they are willing to lend given your income and credit history. Your affordability is determined by what leaves enough margin for everything else in your financial life.
Most people who get into housing loan trouble don't do so because of fraud or bad luck. They do it by taking the maximum loan the bank offered because it got them the property they wanted.
The standard rules — and why they're insufficient
The 40% EMI rule: Standard guidance says keep your home loan EMI under 40% of monthly take-home pay. On ₹1 lakh take-home, that's ₹40,000/month maximum EMI.
The FOIR rule: Banks look at your Fixed Obligation to Income Ratio — total monthly EMI obligations divided by gross income. The safe ceiling is 40-50% FOIR.
These rules are starting points. They don't account for:
- Whether you have children with school fees
- Whether you have dependent parents
- How stable your income is (salaried vs self-employed)
- What your other financial goals are (retirement, travel, education)
- What your emergency fund looks like
A loan that satisfies the 40% rule can still be too large for your specific situation.
Calculate what you can genuinely afford
The full cost of homeownership (not just EMI)
When evaluating affordability, start with your all-in monthly cost of ownership — not just the EMI:
| Cost Component | Approximate Monthly Amount |
|---|---|
| Home loan EMI | Your calculated amount |
| Society maintenance | ₹3,000–8,000 |
| Property tax (amortised) | ₹1,000–1,500 |
| Home insurance | ₹500–800 |
| Repairs and wear (provision) | ₹2,000–3,000 |
| Total | EMI + ₹6,500–13,300 |
If your comfortable EMI is ₹40,000 and these ancillary costs add ₹8,000, your true housing cost is ₹48,000/month — already 48% of a ₹1 lakh take-home. That leaves little room for investment, emergency fund, and discretionary spending.
Warning
Never calculate affordability on your current income alone. Home loans last 15-20 years. Model what happens if one income stops in a dual-income household, if you take a break for health or child, or if your variable pay component shrinks. Can the EMI still be serviced?
How loan tenure affects affordability
The temptation when affordability is tight is to extend the tenure to reduce the EMI. This works mathematically — but at a significant cost.
On a ₹75 lakh loan at 8.75%:
| Tenure | Monthly EMI | Total Interest Paid |
|---|---|---|
| 10 years | ₹93,500 | ₹37.2 lakh |
| 15 years | ₹74,500 | ₹59.1 lakh |
| 20 years | ₹66,000 | ₹83.4 lakh |
| 25 years | ₹61,500 | ₹1.09 Cr |
| 30 years | ₹58,900 | ₹1.37 Cr |
Moving from 20 to 30 years saves ₹7,100/month on EMI — but costs ₹54 lakh more in total interest. Take the shortest tenure your cash flow can support.
Info
A strong approach: take a 20-year loan but prepay aggressively in years 1-5 (when your income is often rising faster than inflation). You can convert a 20-year loan into a 12-year loan through prepayment while maintaining the flexibility of the lower mandatory EMI.
The down payment question
Most buyers treat the down payment as whatever they have saved right now. That's backwards. The right approach is to determine the loan amount you can sustainably afford first, then calculate the down payment as the gap between that loan amount and the property price.
A larger down payment is almost always better:
- Reduces the loan principal and total interest
- May qualify you for a lower interest rate tier (LTV below 75% often gets better pricing)
- Lowers your EMI, creating more monthly margin
- Reduces the risk of being underwater on the property if prices soften
If you haven't saved enough for a 20% down payment, consider delaying the purchase rather than borrowing the down payment or taking a top-up loan. Borrowing your down payment is a fast track to over-leverage.
A practical affordability test
Before committing to a loan, run this sanity check:
- Calculate take-home pay after all existing EMIs, PF deductions, and professional tax
- Subtract 30% of take-home for non-negotiables: groceries, utilities, school fees, existing loans
- Subtract 15-20% of take-home for investments: SIPs, insurance premiums, retirement contributions
- Subtract an emergency margin of ₹5,000-10,000/month
- What remains is your maximum sustainable housing cost (EMI + maintenance)
If the resulting number supports a lower loan than you were planning, take the lower loan. Downsize the property or wait.
When to stretch slightly beyond comfort
There are cases where buying slightly more than your "comfortable" number makes sense:
- Strong and demonstrably rising income with high confidence (promotions, business growth)
- Property is in a location with structural demand drivers (employment corridor, transport infrastructure under development)
- The stretch is temporary — loan will be partially prepaid from a known incoming lump sum (maturity of FD, bonus, ESOP vest)
Even in these cases, the stretch should be modest — no more than 5-7% above your comfortable EMI ceiling. Financial flexibility is worth more than optimising for a slightly larger flat.
FAQ
The follow-up questions people usually ask after the main recommendation is already clear.
What is the maximum home loan I can get on my salary?
Most Indian banks lend 55-60x your monthly take-home salary as maximum loan amount. If your monthly in-hand salary is ₹1.2 lakh, your maximum eligibility is approximately ₹66-72 lakh. However, your eligibility and your affordability are different numbers. Just because a bank will lend you ₹70 lakh doesn't mean you should take it — the EMI must fit within your actual budget.
What is the ideal EMI-to-income ratio?
The RBI and most lenders use a 50% FOIR (Fixed Obligation to Income Ratio) as the maximum — meaning all EMIs combined should not exceed 50% of gross income. In practice, keeping total EMIs (home loan + car + personal loans) at 35-40% of take-home pay gives you enough buffer for other financial goals and emergencies. If your home loan EMI alone exceeds 40% of take-home, reconsider the loan amount.
Should I take a 20-year or 30-year home loan?
Longer tenure means lower EMI but significantly higher total interest paid. On a ₹75 lakh loan at 8.75%: 20-year tenure → EMI ₹66,000, total interest ₹83 lakh. 30-year tenure → EMI ₹59,000, total interest ₹1.37 Cr. The 10-year extension saves ₹7,000/month but costs ₹54 lakh in additional interest. Take the shortest tenure your cash flow can handle.
Is it better to save more for down payment or take the loan now?
Delaying a purchase to save a larger down payment is often the right call. Moving from 10% to 20% down payment reduces your loan by 11% of property value, reduces total interest paid significantly, and may move you from a higher LTV tier to a lower one (reducing the interest rate). The exception: if property prices are rising faster than your ability to save, delaying has a real cost.
What expenses should I budget beyond the EMI?
Home loan EMI is just one part of the true cost of ownership. Also budget for: property registration and stamp duty (6-8% of property value in most metros), interior setup (₹5-15 lakh for a new flat), society maintenance (₹3,000-8,000/month), property tax (₹10,000-20,000/year for a mid-range Bengaluru flat), and home insurance. Factor all of these before finalising the property price you can afford.
