Buying a home is one of the largest financial investments you will ever make. Understanding how the Equated Monthly Instalment (EMI) on a housing loan is structured will help you save lakhs in interest.

How is your Home Loan EMI Calculated?

Your monthly installment consists of two components:

  • Principal Amount: The actual borrowed loan amount.
  • Interest Amount: The cost charged by the bank to lend you the money.

At the start of your loan period, the interest portion dominates the EMI. As you pay off the principal over the years, the interest component decreases and the principal repayment contribution increases.

How Prepayments Can Reduce Tenure

Since housing loans are computed on a reducing balance method, making small annual prepayments directly cuts down your outstanding principal. This significantly reduces your overall loan duration and total interest outgo.
