Home Loans allow you to defer a huge cash outflow to quickly receive possession of a property and repay the debt in affordable instalments.However, first, you need to understand how the interest on a Home Loan is calculated so that you can make informed decisions and plan your finances effectively.

Factors influencing Home Loan interest rates in India

Before understanding how to calculate EMI for Home Loans, you need to know housing loan basics and the factors that can influence the Home Loan interest rate.

  • Repo rate: The Reserve Bank of India (RBI) determines the repo rate. It is the rate at which banks borrow funds from the RBI. Changes in the repo rate can impact lending rates offered by banks and financial institutions, including Home Loan interest rates.
  • Marginal Cost of Funds based Lending Rate (MCLR): MCLR is the benchmark rate that banks use to determine the interest rates on loans, including Home Loans. MCLR considers numerous factors, such as the bank's cost of funds, operational expenses, profit margin and more.
  • Credit score: Your creditworthiness and repayment capability are reflected in your credit score. Thus, credit score plays a significant role in determining your Home Loan interest rate. A higher credit score often results in a lower interest rate, indicating lower credit risk for the lender.

You should also keep in mind that stamp duty and registration charges for Home Loans also come into play during this process, affecting your overall loan amount.

Types of Home Loan interest rates

Banks and financial institutions grant Home Loans using one of the following types of interest rates:

Fixed interest rate

Floating interest rate

  • : Under a fixed interest rate loan, the rate remains constant throughout the loan tenure. This usually assures you of predictable monthly instalments. This type of interest rate is beneficial when interest rates are expected to rise in the future.
  • : A floating interest rate is also known as a variable interest rate. This interest rate fluctuates with changes in the market and is linked to external benchmarks such as the MCLR or the repo rate. This type of interest rate offers flexibility as it allows you to benefit from rate changes. It is open to the possibilities of rate reductions in the future but may also result in increased EMIs if interest rates rise.
