From eligibility to prepayment strategy — everything in one place.
A home loan is the largest financial commitment most Indians will ever make. Getting it right — from the type of rate to the repayment strategy — can save you lakhs and years.
A home loan works on the reducing balance method. Each month, interest is calculated on the outstanding principal — which decreases as you repay. Your EMI stays fixed, but the split between interest and principal shifts over time.
Your monthly EMI is calculated using:
EMI = P × r × (1 + r)^n ÷ [(1 + r)^n − 1]
Where P = principal, r = monthly interest rate (annual rate ÷ 12), n = total months. A ₹50 lakh loan at 8.5% for 20 years gives an EMI of ₹43,391.
In the early years of a home loan, most of each EMI goes toward interest, not principal. In year 1 of a ₹50L / 8.5% / 20-year loan: 82% of every EMI is interest. By year 15, that drops to about 43%. This front-loading is why prepaying early saves so much more than prepaying later.
Banks use two primary factors to decide your loan eligibility: your income (which determines how much EMI you can service) and the property value (which determines the LTV ratio).
Most lenders cap your total monthly loan obligations (all EMIs combined) at 40–50% of your gross monthly income. A simpler rule of thumb used by many banks: you are eligible for a home loan of roughly 60× your monthly net take-home salary.
Approx. eligible loan: ₹18–20 lakh
Based on 40% EMI-to-income ratio at 8.5% for 20 years.
Approx. eligible loan: ₹35–40 lakh
A ₹40L loan EMI at 8.5%/20yr = ₹34,713 — fits within 40% threshold.
Approx. eligible loan: ₹55–65 lakh
A ₹60L loan EMI = ₹52,069 — comfortably within 50% of income.
Banks don’t fund 100% of the property value. The LTV (Loan-to-Value) ratio determines the maximum loan amount based on property value:
On a ₹60 lakh property, the bank funds a maximum of ₹48 lakh (80%). You must bring ₹12 lakh as a down payment from your own savings.
A CIBIL score of 750+ unlocks the best rates and highest loan amounts. A score below 650 can lead to rejection or significantly higher interest rates. Before applying, check your credit report for errors, clear outstanding credit card dues, and avoid multiple loan applications in a short period (each inquiry slightly lowers your score).
Your interest rate type determines how your EMI behaves over the loan tenure, and how much you benefit (or lose) from RBI rate cycles.
Linked to the RBI Repo Rate via the EBLR system (mandatory since October 2019). Your rate = Repo Rate + Lender’s Spread. When the RBI cuts rates, your cost falls automatically. Starting rates are typically 1–2% lower than fixed, and there is no prepayment penalty (per RBI mandate).
Rate locked for a period — but in India, true lifetime-fixed loans are rare. Most “fixed” products are fixed for 2–5 years, then reset to floating. Fixed costs more upfront: a 1% rate difference on a ₹50L / 20-year loan means ₹7.8 lakh more in total interest.
For most borrowers with a tenure of 15+ years: choose floating rate. The lower starting rate, free prepayment, and long-term rate averaging almost always outperform a fixed rate. Stress-test your EMI at a rate 2% higher than current — if you can still manage it, floating is your best option.
A home loan is one of the few financial products that offers two simultaneous tax deductions under the Old Tax Regime:
Total annual deductions: up to ₹3.5 lakh. At the 30% tax bracket: up to ₹1,05,000 saved in taxes every year.
The New Tax Regime (default from FY 2024–25) does not allow either the Section 80C or Section 24(b) deduction for self-occupied property. If your home loan deductions are significant, compare total tax liability under both regimes before choosing. For high-income borrowers with a large loan, the Old Regime often saves more overall.
On a ₹50 lakh loan at 8.5%, your total interest bill over 20 years is ₹54.1 lakh. A small, consistent prepayment dramatically changes this equation:
Why does early prepayment save so much more? Because interest is front-loaded. In the first few years, a prepayment saves you 3–5x more in future interest than the same amount prepaid in year 15.
RBI rule: Floating-rate home loan borrowers face zero prepayment penalty — you can prepay any amount at any time, free of charge. The single most powerful move for most borrowers: direct your annual bonus entirely to a lump sum prepayment in the first 5 years of the loan.
Whether buying a home makes more financial sense than renting depends on several factors unique to your city, income, and investment discipline.
If the annual rent for a property is less than 5% of its purchase price, renting is often cheaper in the short-to-medium term when you account for the opportunity cost of the down payment, property taxes, maintenance, and loan interest. Example: a ₹80 lakh flat with annual rent of ₹3 lakh = 3.75% yield — financial case for renting is strong unless you plan to hold the property for 15+ years.

Open EMI Calculator →For a ₹50 lakh home loan at 8.5% for 20 years, the monthly EMI is approximately ₹43,391. Most banks cap total loan EMIs at 40–50% of gross monthly income. This means you typically need a gross monthly salary of around ₹87,000–1,09,000 to comfortably qualify for a ₹50 lakh loan from most banks.
A co-applicant (spouse or parent with income) significantly improves eligibility — the combined income is used to assess the FOIR, often allowing a higher loan amount than either applicant could secure individually.
The down payment depends on the property value and the LTV (Loan-to-Value) ratio your bank applies:
On top of the down payment, budget for registration and stamp duty (5–8% of property value in most states), GST (for under-construction properties), and processing fees (0.25–1% of loan amount). Total upfront cash outflow is often 30–35% of the property value.
Shorter tenure = lower total interest, higher monthly EMI. Longer tenure = lower monthly EMI, significantly higher total interest cost.
For a ₹50 lakh loan at 8.5%:
The practical approach: choose a longer tenure to keep the EMI manageable, then prepay aggressively to reduce tenure. This gives you cash flow flexibility while still minimising total interest paid. Never stretch tenure beyond 20 years unless absolutely necessary.
This depends on the loan stage and your risk tolerance. In the first 8–10 years of a home loan, prepayment typically makes more sense because:
After year 10, the interest component of each EMI falls significantly. At this point, investing in equity (historically 11–13% CAGR) often beats prepaying the loan. A practical split: 60% to prepayment + 40% to equity SIPs in early years; flip to 40:60 after year 10.
Once disbursed, a home loan is not affected by a job change as long as you continue paying EMIs on time. Your bank does not re-assess your eligibility or change the loan terms when you switch employers. However:
Standard documents required by most banks:
Requirements can vary by lender. Pre-approval processing typically takes 3–7 working days once all documents are in order.
