EMI or Equated Monthly Installment has grown into an important part of the modern financial life. EMI helps you to buy expensive goods at a manageable price, be it a smart phone, car or home. When you know EMI, you will be able to spend your money wisely and make informed borrowing choices.

What Exactly is EMI?

EMI (Equated Monthly Installment) is a fixed amount of money that a borrower pays to a lender at a specific day on a monthly basis. The loan is repaid in a predetermined number of years with the help of EMIs which allow paying the principal and interest on a monthly basis.

Official Definition

Equated monthly installment (EMI) is a fixed amount of payment paid by a borrower to a lender on a predefined date every calendar month. The loan is decided to be paid in full within a specified number of years through the use of equated monthly payments to settle the loan together with the interest accrued at the time.

How Does EMI Work?

The act of splitting a loan into a series of fixed payments over a period is known as the amortization and that is how EMI is performed. The procedure is as follows:

1

Loan Disbursement

The lender gives you or the seller the entire sum of the loan.

2

EMI Calculation

The amount of payment per month that you are to pay is fixed depending on the loan amount, interest rate, and tenure.

3

Regular Payments

You pay it every month on a specified date.

4

Interest-Principal Split

Each EMI payment covers interest at that period of time and a part of the principal.

5

Loan Completion

Loan would be fully paid with interest once all EMIs have been paid.

Components of EMI

Any EMI payment is a combination of two elements:

Principal Amount

The exact amount of the loan you had borrowed. This percentage is increasing with each EMI.

Pays off your default loan

Interest Amount

The cost of money is expressed in the percentage of the value of the unknown debt.

Expense incurred in borrowing money

Variation of EMI Composition with Time

Interest (80%)
Principal (20%)
Early EMI (More Interest)
Interest (50%)
Principal (50%)
Middle EMI (Balanced)
Interest (20%)
Principal (80%)
Final EMI (More Principal)

How is EMI Calculated?

EMI is calculated with a common mathematical formula that will ensure your loan is well repaid within the choice of time.

EMI Formula
EMI = [P × r × (1 + r)^N] ÷ [(1 + r)^N − 1]
P
Principal Loan amount borrowed
r
Monthly Interest Rate Annual rate ÷ 12 ÷ 100
N
Tenure in Months Loan period in months

Loan Amount: ₹5,00,000
Interest Rate: 12% p.a.
Tenure: 3 years (36 months)
Monthly EMI: ₹16,607
Total payable: ₹5,97,852 | Interest: ₹97,852
