Home Loan EMI Calculator

How your home loan EMI is calculated

An EMI — equated monthly instalment — is the fixed amount you pay the bank each month until the loan is cleared. Every instalment is split in two: interest on the balance you still owe, and the rest, which reduces that balance. Because the balance falls a little each month, the interest portion shrinks and the principal portion grows, even though the instalment itself stays the same.

The calculation uses the standard reducing-balance formula, where the principal is the amount borrowed, the monthly rate is the annual rate divided by twelve, and the number of instalments is the tenure in years multiplied by twelve. The amortisation table above shows this month by month, so you can see exactly when the balance starts falling quickly.

What changes your EMI

Property price

Everything starts here. A higher price means a bigger loan for the same down payment, and a proportionally higher instalment.

Down payment

Whatever you pay upfront is not borrowed and carries no interest. Raising the down payment is the most direct way to cut both the EMI and the total interest.

Loan amount

Banks typically finance a share of the property value rather than all of it, so the loan is usually less than the price. Registration and stamp duty are normally paid from your own funds.

Interest rate

Even a small difference matters over twenty years. Compare offers from more than one bank, and check whether the rate is fixed or floating.

Tenure

A longer tenure lowers the monthly instalment but increases the total interest paid, because you are borrowing for longer. A shorter tenure does the opposite.

Ways to pay less interest

• Put down more upfront. Try the down payment slider above — raising it even a few percent usually removes lakhs from the total interest.
• Negotiate the rate. Approach more than one lender. A clear-title, approved property strengthens your position considerably.
• Prepay when you can. A bonus or a good year put against the principal shortens the loan, because interest is charged on the outstanding balance.
• Choose the tenure honestly. Pick the shortest tenure whose instalment you can comfortably afford in a difficult month, not just a good one.
• Raise the EMI as your income grows. Many lenders allow the instalment to be increased later, which closes the loan years earlier.
