What is Home Loan EMI

  • The full form of EMI is Equated Monthly Installment
  • This is the amount you pay every month for the home loan you have taken. 
  • EMI depends on the home loan interest rate, tenure (for how many years you are taking loan) and also it depends on your yearly Income, since you should be able to afford the resulting EMI of your home loan from your Income. 
  • In above video, I have explained how home loan EMI is calculated using PMT formula of Excel.
  • Your EMI consists of 2 things: Principal Amount & Interest Amount
  • Principal Amount is less initially and it increases with tenure. This means, as you pay your EMI, principal amount with every EMI will increase
  • Interest Amount is high initially and it decreases with tenure, This means, more interest is taken from you initially compared to when your loan is about to get over
  • This proves that you should try to make prepayments during the initial months of your loan to save maximum home loan interest compared to making prepayments during the end of loan

Below is the screenshot showing Principal Amount less and Interest Amount high during the initial months of loan:

As seen in above screenshot, Principal amount (less initially) is increasing with tenure and Interest Amount (high initially) is decreasing with tenure.

Home Loan Calculation Method

You can easily use PMT formula of Excel to calculate home loan EMI. Here is the formula:

EMI = PMT(rate, nper, pv, [fv], [type])
rate – Yearly Interest rate / 12 / 100
nper – Number of months remaining (tenure remaining)
pv – Current outstanding Principal value
fv – 0
type – 0

As you can see above, rate is the yearly home loan interest rate divided by 12 to get monthly interest rate and then divided by 100. nper is the number of months remaining in loan, pv is the outstanding principal amount remaining in your loan.

Here’s the screenshot of the PMT formula resulting the EMI example:

Principal Amount = Rs. 30 Lacs
Interest rate = 7%
Tenure = 10 Years (120 Months)
EMI = Rs. 34,832.54

Home Loan Interest Rate

  • As mentioned above, home loan interest rate is one of the factors affecting the interest you’ll be paying throughout your loan tenure. 
  • Higher the interest rate, more Interest you’ll be paying. Less Interest rate means you’ll pay less Interest throughout your loan tenure. 
  • You should research and try to find your loan with less interest rate to pay less interest for your home loan. 
  • Currently the home loan interest rate in India can range anywhere between 7% – 10% per year. If you get home loan below this range, it’s a good bet for you.

How to Save Home Loan Interest

  • Home Loan Interest can be saved by making loan prepayments when your loan is already disbursed
  • If you are looking to save loan interest before you apply for loan, you should go with lowest interest rate and lowest tenure
  • While you go for lowest tenure, your EMI will be higher since you are taking loan for less period of time
  • Another way to save loan interest is the increase your EMI every year by some percentage, in which case your loan tenure will be reduced that reduces home loan interest

Home Loan Prepayment Examples & Formula

As mentioned above, you can save home loan interest paid by you by making prepayments.

  • While making prepayments, you can either choose to reduce EMI or Tenure
  • Reducing tenure is the better option since it reduces the term for which you’ll be paying EMI
  • Reducing EMI will still keep the tenure same, hence you’ll be paying more interest compared to reducing tenure option
  • In case of variable interest rate, you can prepay your loan any number of times in a FY
  • In case of fixed interest rate, banks impose some rules related to when your can make prepayment and how frequently the prepayments can be done. It depends on the bank from which loan is taken

Income Tax Saving using Home Loan

One important factor about home loan apart from you buying your own home is, home loan helps you Save Income Tax under Section 80C and Section 24.

  • Home Loan Principal Amount you pay can be claimed under Section 80C (Maximum Rs. 1.5 Lacs in a FY)
  • Home Loan Interest Amount you pay can be claimed under Section 24 (Maximum Rs. 2 Lacs in a FY)
  • Maximum of Rs. 3.5 Lacs can be claimed by you in a Financial Year which helps you save Income Tax by reducing your Taxable Income.
