How this home loan EMI calculator works
EMI stands for equated monthly instalment, the fixed amount you pay your lender each month until the loan is repaid. Early in the loan most of each EMI is interest, and over time more goes towards the principal. The calculator uses the standard formula:
EMI = P × r × (1 + r)n ÷ ((1 + r)n − 1), where P is the loan amount, r is the monthly interest rate (the annual rate divided by 12 and by 100) and n is the number of months. For a ₹40 lakh loan at 9% for 20 years, r is 0.0075 and n is 240, which gives an EMI of ₹35,989.
Three steps make this calculator specific to buying a flat in Kolkata:
- The maximum loan. The RBI sets limits by loan size: a lender can finance up to 90% of the property value for loans up to ₹30 lakh, 80% for loans above ₹30 lakh and up to ₹75 lakh, and 75% above that. The calculator finds the largest loan that stays within those limits for your flat price, and the rest is your minimum down payment.
- Stamp duty and registration. Lenders do not finance these, so you pay them in cash. The calculator uses 6% stamp duty up to ₹1 crore (7% above) plus 1% registration, the urban rates in our guide to stamp duty and registration charges.
- Cash needed upfront. This is your down payment plus stamp duty and registration, the money you need before the first EMI. GST, maintenance deposits, legal fees and loan processing fees are not included.

How to reduce your EMI or the interest you pay
- Pay a larger down payment. Every lakh you do not borrow cuts both the EMI and the interest.
- Choose the tenure carefully. A longer term lowers the EMI, but on a ₹40 lakh loan at 9% it raises the total interest from about ₹46.4 lakh over 20 years to about ₹75.9 lakh over 30 years.
- Prepay when you can. Part-payments reduce the principal and the interest. Ask your lender about any prepayment charges first.
- Compare lenders. A small difference in the rate, plus processing fees, adds up over many years.
- Check your credit score before you apply, because it can affect the rate you are offered.
The interest subsidy under PMAY-Urban 2.0 may also apply to some buyers of flats up to ₹35 lakh, subject to income and other rules. See our guide to 1 BHK flats in Kestopur under ₹30 lakh.
