Paying full EMI from the first disbursement saves ₹6,16,646 in interest and ends the loan 2 years sooner. It costs ₹1,00,983 more during construction, when you may also be paying rent.

What is pre-EMI?
When you buy an under-construction flat, the bank does not pay the builder the whole loan at once. It pays in stages as construction progresses (foundation, each slab, finishing), usually against a demand letter from the builder. Until you get possession and the full loan is disbursed, you pay only the interest on the amount released so far. That monthly interest is the pre-EMI. It clears no principal, so the loan you owe on the day of possession is the full sanctioned amount.
How pre-EMI is calculated
Pre-EMI for a month = amount disbursed so far × annual rate ÷ 12 ÷ 100. On ₹10 lakh disbursed at 8.5%, it is ₹7,083 a month; when the next stage brings the total to ₹20 lakh, it doubles to ₹14,167. The regular EMI on the whole loan starts after possession and runs for the full tenure, so the loan ends later than it would have if you had started EMIs straight away.
Pre-EMI vs full EMI
Most banks offer a second option: start paying full EMI on the disbursed amount from the first disbursement. Part of each payment then goes to principal, and the tenure clock starts early, so the loan finishes sooner and total interest is lower. The catch is cash flow: during construction many buyers also pay rent, and pre-EMI keeps the monthly outgo small. The comparison above shows both side by side for your numbers.
Tax on pre-EMI interest
Under the old tax regime, interest paid before possession is not deductible in the year you pay it. Instead, the total pre-construction interest is claimed in five equal parts, starting from the year construction is completed, within the overall ₹2 lakh a year limit for a self-occupied home under section 24(b). Principal in pre-EMI is zero, so there is no 80C claim until regular EMIs begin.
Delays and the builder's schedule
If construction is delayed, you keep paying pre-EMI for longer and the total interest grows with every month. Put a realistic time to possession in the calculator, not the brochure date, and check the builder's payment plan for the number of stages. Some buyers choose a subvention scheme where the builder pays the pre-EMI; read the terms, because if the builder stops paying, the bank will ask you.
