How does a step-up EMI work?

A step-up EMI, just like the step-up-SIP that amplifies your wealth, is a way to quickly pay off your home loan so that you save both interest and time. If your home loan is paid off quickly, thanks to salary and income increases, it will likely increase the value of your retirement portfolio: How much lower portfolio value do you end up with if you do not invest for a few years in between?

Before we get into the details of how the Step-up EMI is beneficial, we will recap how a home loan works.

How does a home loan work?

Mortgage payment vs home equity

The bank gives a home loan to own the property while you use it until you pay back the loan via EMIs. An Equated Monthly Instalment plan (EMI) is a standard way to pay off a loan by making a fixed payment monthly that includes both interest and principal in the same amount.

EMI = Principal + Interest

In each EMI, the split of the interest and principal changes since the interest is based on the outstanding loan balance at that point and the rest of the EMI is principal. As the chart shows, the interest part drops off with time, and the rest is the principal. The actual numbers in the chart relate to a ₹50 lakhs home loan taken at 8% for 25 years. The EMI is ₹38,591. The down payment amount is ₹12.5 lakhs.

You can test the numbers using this calculator:

As you pay back the loan, your ownership share in the house will increase in the same way. At the point of taking the loan, you own 20% of the house (12.5 out of 62.5, of which 50 is the loan). The bank owns 80%. As the loan is repaid, you own more and more of the house as the principal is paid off. This is the concept of building equity in an asset. Equity is the part of the asset you own after subtracting the part that the bank owns.

Home equity value = Current home value - Outstanding loan balance

Once you build equity in your home, that has additional benefits:

  • You can take a top-up loan in case you need money for some other purpose like home improvement or any other reason.
  • The more you will get to keep if you sell the house.

We break down the home loan rate into its major components to see where the fluctuations come from.

Repo linked home loan rate = Repo Rate + Spread + Premium

Repo rate: This rate is decided by the RBI. Home loan rates will move up and down as soon as the RBI revises the repo rate.

The latest repo rate is 6.5%. This rate was last reviewed by the RBI on 08 Feb 2024.

Spread: This is an additional rate on top of the repo rate that essentially captures the profit the bank can make off this loan relative to the deposits it offers to customers. This rate is generally revised every three years but will vary from bank to bank.

Premium: An extra value for some specific customers. For example, SBI adds another 15 bps for non-salaried customers or it will depend on the CIBIL score of the borrower. This value is also revised periodically, like every three years.

Continuing the ₹75 lakhs 15-year home loan at 9% example, the normal EMI looks like this:

Home loan repayment schedule with fixed EMI

In contrast, the 10% step-up EMI pays off the loan in 43% less time (and saves 36% of the interest).

Home loan repayment schedule with Step-up-EMI with 10 percent yearly step-up

We will now quantify the savings involved via a step-up EMI for your home loan.

How to pay off your home loan automatically via step-up EMI?

Year Normal EMI 10% Step-up EMI Extra EMI
1 ₹77,537 ₹77,537 ₹0
2 ₹77,537 ₹85,290 ₹7,754
3 ₹77,537 ₹93,820 ₹16,283
4 ₹77,537 ₹1,03,201 ₹25,665
5 ₹77,537 ₹1,13,522 ₹35,985
6 and so on

Your loan-issuer bank will create an Electronic Clearing System (ECS) instruction to automatically debit your loan EMI. You should talk to your bank about getting the loan-account number and IFSC code of the servicing branch. Then you can map the account as a beneficiary in Net-banking and setup a NEFT standing instruction to automatically pay the step-up amount i.e. the extra EMI soon after you get salary every month. Some banks even offer UPI payments to the loan account. Once a year, login into Net-banking and increase the standing instruction amount. If the loan EMI changes due to repo rate change, adjust the step-up amount as well.

As per RBI circulars DBOD.No.Dir.BC.107/13.03.00/2011-12 dated June 5, 2012, and the subsequent circular DBOD.Dir.BC.No.110/13.03.00/2013-14 dated May 7, 2014, banks cannot charge pre-payment penalty any more on home loans.
