Home loan EMI calculator
Work out your monthly home-loan EMI, total interest and total payment. Adjust the amount, rate and tenure to plan your budget before you build or buy.
How EMI is calculated
EMI (equated monthly instalment) is found with the standard formula EMI = P x r x (1+r)^n / ((1+r)^n – 1), where P is the loan amount, r is the monthly interest rate (annual rate divided by 12 and by 100), and n is the number of monthly instalments (years x 12).
Example
On a Rs 40 lakh loan at 8.75% for 20 years, the EMI is about Rs 35,350, with total interest of roughly Rs 44.8 lakh over the loan term. Lowering the tenure raises the EMI but cuts total interest sharply.
Tips to lower your EMI or interest
A larger down payment reduces the principal. A shorter tenure raises the EMI but lowers total interest. Even a small rate difference between lenders changes your total payment significantly, so compare offers.
What actually drives your EMI
Three inputs decide everything: the amount borrowed, the interest rate, and the tenure. Take ₹40 lakh at 8.75 percent over 20 years. The EMI works out to about ₹35,350 a month, you repay roughly ₹84.8 lakh in total, and about ₹44.8 lakh of that is interest. Over a long tenure you can easily pay more in interest than you borrowed, which is the single most useful thing to understand before signing.
The tenure trade-off
Lengthening the tenure is the usual advice when an EMI feels unaffordable, and it works: the monthly figure drops. What it also does is increase the total interest substantially, because you are borrowing the same money for longer.
| ₹40 lakh at 8.75 percent | Monthly EMI | Total interest |
|---|---|---|
| Over 10 years | Higher, around ₹50,200 | Roughly ₹20.2 L |
| Over 20 years | About ₹35,350 | Roughly ₹44.8 L |
| Over 30 years | Lower, around ₹31,500 | Roughly ₹73.3 L |
Going from 20 years to 30 saves a few thousand a month and costs a great deal more overall. Neither choice is wrong; the point is to make it knowingly rather than accept the longest tenure because it makes the EMI look comfortable.
Why early prepayment does so much
Interest is charged on the outstanding balance, so in the early years most of each EMI is interest and only a small part reduces the principal. A prepayment made in year two therefore removes far more future interest than the same amount paid in year twelve. If you expect bonuses or lump sums, directing them at the loan early is where they do the most work. Floating-rate home loans in India generally carry no prepayment penalty for individual borrowers, but confirm that in your own agreement.
If you are building rather than buying
A construction loan is released in stages against verified progress, and during construction many lenders charge interest only on the amount actually disbursed. Full EMIs typically begin once the loan is fully drawn. So your early outgo is smaller than this calculator shows, and the full EMI starts later than you might assume. Plan the gap, especially if you are also paying rent while building.
What this excludes
- Processing fees and documentation charges
- Property insurance or loan protection cover, sometimes bundled at sanction
- Interest rate changes on a floating loan, where lenders often adjust tenure rather than EMI
- Stamp duty and registration, which are not funded by the loan
Common questions
My rate changed. Why is my EMI the same?
On floating-rate loans lenders commonly adjust the tenure instead of the EMI, so the monthly amount stays put while the loan runs longer or shorter. Ask your lender which lever they used, because a quietly extended tenure can add years without you noticing.
Should I take the longest tenure available?
Only if you need the lower EMI for cash-flow comfort. A middle path many borrowers use is to take a longer tenure for safety, then prepay when able, which keeps the monthly commitment manageable while still cutting total interest.
