A ₹40 lakh home loan sits right between India's two most common ticket sizes - a step up from a ₹30 lakh loan, a step below ₹50 lakh. At the typical rate of 8.5% per annum over a 20-year tenure, the monthly EMI works out to ₹34,713. Over the full tenure, you'll pay ₹83,31,103 in total - ₹43,31,103 of that is interest.
This article covers the exact calculation, how EMI changes across different tenures and rates, and a prepayment example showing how much you can realistically save.
Indian lenders use the reducing balance method, where interest is charged only on the principal still outstanding:
Plugging in the values: EMI = ₹34,713 per month. Over 20 years, your total outgo is ₹83,31,103 against a principal of ₹40 lakh - interest makes up over 52% of everything you pay, which is typical for a 20-year home loan at this rate.
Tenure is the lever most borrowers underestimate. A longer tenure looks affordable on paper, but the interest cost compounds fast:
| Tenure | Monthly EMI | Total Interest | Total Payment |
|---|---|---|---|
| 10 Years | ₹49,594 | ₹19,51,313 | ₹59,51,313 |
| 15 Years | ₹39,390 | ₹30,90,125 | ₹70,90,125 |
| 20 Years ✦ | ₹34,713 | ₹43,31,103 | ₹83,31,103 |
| 25 Years | ₹32,209 | ₹56,62,725 | ₹96,62,725 |
| 30 Years | ₹30,757 | ₹70,72,354 | ₹1,10,72,354 |
Key insight: Going from 20 to 30 years lowers the EMI by only ₹3,956 a month, but adds ₹27,41,251 in interest - almost as much as the entire principal again. Beyond 20-25 years, the EMI savings per additional year shrink quickly while the interest cost keeps climbing.
Home loan rates for salaried borrowers with a good credit score typically range from 7.5% to 10% depending on the lender and prevailing repo rate. Here's the impact of rate on your EMI and total cost:
| Interest Rate | Monthly EMI | Total Interest | Total Payment |
|---|---|---|---|
| 7.5% | ₹32,224 | ₹37,33,695 | ₹77,33,695 |
| 8.0% | ₹33,458 | ₹40,29,825 | ₹80,29,825 |
| 8.5% ✦ | ₹34,713 | ₹43,31,103 | ₹83,31,103 |
| 9.0% | ₹35,989 | ₹46,37,369 | ₹86,37,369 |
| 9.5% | ₹37,285 | ₹49,48,459 | ₹89,48,459 |
| 10.0% | ₹38,601 | ₹52,64,208 | ₹92,64,208 |
Just a 1% difference in rate - from 8.5% to 9.5% - costs an extra ₹6,17,356 over 20 years on a ₹40 lakh loan. It's worth spending a few days comparing offers or negotiating with your existing bank before signing, since the savings compound over the full tenure.
If you pay an additional ₹5,000 per month over your regular EMI of ₹34,713, starting from the first month:
Nearly ₹13 lakh saved by paying nine extra EMIs' worth spread across the loan's life - roughly 14% more than the regular EMI, every month.
Since April 2025, RBI's rules bar lenders from charging foreclosure or prepayment penalties on floating-rate home loans taken by individuals for non-business purposes - so for most home loans, this kind of prepayment is genuinely free. Use the EMIPlan Prepayment Simulator to model different extra-payment amounts against your own loan.
Lenders typically cap your EMI at 40-50% of your monthly take-home income. For a ₹34,713 EMI, that generally means a monthly income of roughly ₹75,000-₹85,000, though this varies by lender and your existing obligations.
Public sector banks, private banks and housing finance companies all price differently, and the "best" lender changes with market conditions. A 0.5% difference on ₹40 lakh over 20 years is worth over ₹3 lakh in interest.
Banks often quote the longest tenure you qualify for since it maximizes their interest income. If your budget allows a 15-year tenure instead of 20, you'd save over ₹12 lakh in interest on this loan size.
Processing fees (typically 0.5%-1% of the loan amount), legal and technical valuation charges, and stamp duty/registration on the property add up separately from your EMI - factor these into your total cash outlay upfront.
A single yearly lump-sum prepayment - even ₹50,000-₹1,00,000 - made early in the loan's life has an outsized effect on total interest, since more of your EMI is still going toward interest at that stage.
