Picture a couple in Pune eyeing a flat priced at Rs 60 lakh. They've saved hard, but the bank won't hand over the full amount. It rarely does. Home loans in India usually cover around 80 percent of the property value, which means the buyer brings the rest from their own pocket. That gap has a name, and getting it wrong derails a lot of first-time purchases.
Down payment comes first, then the loan
The slice the bank lends against your home is its loan-to-value, and lenders typically cap it near 80 percent. So on that Rs 60 lakh flat, the loan might be about Rs 48 lakh and the buyer arranges roughly Rs 12 lakh upfront. Stamp duty and registration sit on top, paid separately. Many people forget those. They budget for the flat and then scramble when the sub-registrar's office asks for another few lakh.
Why does this matter for the EMI? Because the EMI is built only on the loan amount, not the full price. A bigger down payment shrinks the loan, and a smaller loan means lighter monthly outgo and less interest over the years.
Run the numbers for that Pune flat
Take the Rs 48 lakh loan at around 8.5 percent over 20 years. The EMI lands near Rs 41,600 a month. Stretch the tenure to 30 years, which several banks now allow, and it drops to roughly Rs 36,900. Lower monthly pain, but you pay a lot more interest across those extra ten years. Tenure is a lever. Pull it carefully.
The calculator uses the standard EMI formula, where each payment splits between interest on the outstanding balance and a chunk that chips away at the principal. Early on, interest dominates. The split flips slowly as the years pass.
The tax angle most buyers underuse
Here's where a home loan beats almost every other borrowing. Under Section 80C, the principal you repay each year qualifies for deduction, sharing that limit with your PF, ELSS and insurance. And under Section 24b, the interest on a self-occupied home is deductible up to a yearly cap. Together these can knock a real amount off your tax bill, so the effective cost of your loan is lower than the rate on paper.
A few honest cautions. Rates float, so your EMI can move at reset time. The tax limits and exact deduction caps change with budgets, so check current rules before you bank on a number. And don't drain every last rupee into the down payment. Keep a cushion. A new home has a way of demanding repairs, deposits and a fridge the week you move in.
Mortgage Calculator — frequently asked questions
How much down payment do I need for a home loan in India?
Most banks fund around 80 percent of the property value, so you arrange roughly 20 percent yourself. On a Rs 50 lakh flat that's about Rs 10 lakh from your savings. Remember stamp duty and registration are charged separately and aren't part of the loan, so keep extra aside. A bigger down payment lowers your EMI and total interest, so pay more if you comfortably can.
Does a longer tenure reduce my home loan EMI?
Yes, stretching the tenure lowers each monthly payment because the loan is spread across more months. But you end up paying far more interest overall. A 30-year loan feels easier month to month than a 20-year one, yet costs lakhs more by the end. Pick the shortest tenure your budget can handle, and consider prepaying when you get a bonus or raise to cut the interest burden.
What tax benefits can I claim on a home loan?
Under the old regime, the principal repaid qualifies under Section 80C, sharing that yearly limit with PF, ELSS and insurance premiums. The interest portion is deductible under Section 24b for a self-occupied home, up to a yearly cap. These deductions lower your taxable income, so your effective borrowing cost drops. The exact limits get revised in budgets, so check current rules before planning around a fixed figure.
What is loan-to-value ratio in a home loan?
Loan-to-value is the share of the property's value that the bank is willing to lend. In India it usually sits near 80 percent, though it can be lower for higher-priced homes. So if your flat costs Rs 60 lakh, the loan might be around Rs 48 lakh and you fund the rest. A lower LTV means you borrow less, pay a smaller EMI and carry less interest.
Is the home loan EMI fixed for the whole tenure?
Not usually. Most home loans in India are on floating rates linked to an external benchmark, so when that benchmark moves your rate resets. Banks often keep the EMI steady and adjust your tenure instead, or change the EMI at reset. Fixed-rate options exist but tend to cost more. Read your sanction letter carefully so you know how your lender handles rate changes.
Should I make a bigger down payment or invest that money?
It depends on what your money can earn elsewhere versus your loan rate. A bigger down payment guarantees you save interest at the loan rate, which is a sure return. Investing might beat that, but it isn't certain. Many buyers split the difference, paying a healthy down payment while keeping an emergency cushion. Never empty your savings completely, because a new home brings unexpected costs almost immediately.
