What Is an Equated Monthly Installment (EMI)?

Financial institutions, from credit unions to personal loan lenders, use the acronym "EMI" in loan documents. It stands for "equated monthly installment," and represents how much you will pay on a loan each month. Here, we'll explain how EMI works and how it impacts your monthly budget.

What does "equated monthly installment" mean?

When you take out an installment loan, whether it's a home loan, car loan, personal loan, or business loan, you agree to make a monthly payment. This payment stays the same from month to month. Because every monthly payment is equal, these payments are called "equated monthly installments." You agree to make those payments until the loan is paid in full.

An equated monthly installment (EMI) includes principal, interest, and sometimes, fees rolled into the loan by the lender.

You can use the calculator below to calculate the EMIs of different loans.

How do you calculate an equated monthly installment?

To calculate loan EMI, you need four things:

  • The amount you're borrowing
  • The interest rate on the loan
  • The loan term (how long you can take to repay the loan in full)
  • Loan fees, if any

For instance, let's imagine that you borrow $200,000 at an annual interest rate of 4% for 15 years. You pay no fees.

Amount borrowed $200,000
Interest rate 4%
Loan term 15 years
EMI $1,479

The EMI payment breakdown looks like this:

  • You borrow $200,000.
  • At 4%, you pay $66,288 in interest.
  • The actual amount you have to pay back, therefore, is $266,288 ($200,000 + $66,288).
  • You have a 15-year loan term (180 months), so the EMI dictates that you make equal monthly payments of $1,479 ($266,288 ÷ 180 equal payments = $1,479).

What about fees?

Often, when you take out a loan, the lender adds an origination fee and various closing costs. If the lender rolls those fees into the loan, they also become part of the EMI calculation. Let's look at an example with fees.

Let's say you take out a personal loan for $15,000 at an annual interest rate of 6%. The loan term (sometimes referred to as the "loan tenure") is 60 months, and the lender rolls $300 of fees into the loan.

Amount borrowed $15,000
Fees $300
Interest rate 6%
Loan term 60 months
EMI $296

Here's the breakdown of this EMI payment:

  • You borrow $15,300 (the original loan amount plus fees the lender rolled into the loan).
  • At 6%, you pay $2,448 in interest.
  • That means the actual cost of the loan is $17,748 ($15,300 + $2,448).
  • You have a 60-month loan term, so the EMI dictates that you make equal monthly payments of $296 ($17,748 ÷ 60 equal payments = $296).

Scientific calculation

The official calculation for EMI is: P = L[r(1 + rn] / [(1 + r)n - 1]

While it is unlikely you will need to know the exact formula, the important thing to remember about EMI is that it is calculated by adding your principal balance to the interest paid, and dividing that total by the number of months you have to pay the loan.

Rate shopping

Shopping around for a lender is important, because you can't always determine which loan will be least expensive by solely comparing interest rates. While the loan interest rate is important, it doesn't tell the entire story.

Fees vary widely by lender. While one lender may charge a slightly higher interest rate, that lender may offer loans with no fees. Another may advertise a lower rate, but tack on fees that mean you pay more in total.

If a lender charges $750 in fees, you don't just pay $750. When the fees are rolled into the loan, you also pay interest on that $750. Here's how much extra you'll pay:

Fees (without interest) $750
Interest rate 6%
Loan term 60 months
Interest paid on fees alone $120
Actual cost of fee (original fee + interest) $870

Why does loan EMI matter?

EMI tells you how much you'll pay each month if you have a fixed-rate loan. EMI also helps you create a budget with confidence that there aren't going to be any surprises.

Loan EMI gives you a lot you need to know as a borrower, from how much the interest payment will be every month to how much you will pay in total over the repayment term. In short, EMI makes you a savvier borrower. Once you know how much your monthly payments will be, you are better equipped to live with financial confidence.
