Equated Monthly Instalment, or EMI for short, is a fixed monthly payment that borrowers make to lenders to cover principal and interest on loans and large purchases.
What is EMI?
The agreed-upon amount that borrowers pay lenders on a regular basis (typically monthly) over a predetermined loan period is known as the EMI. The most common way to pay back loans, including personal, auto, and home loans, is through installment plans (EMIs), which each include a portion of the principal and any applicable interest.

Importance of EMI
By dividing repayments into manageable amounts, EMIs help make expensive purchases affordable. This helps borrowers better manage their spending and avoid financial strain, enabling them to obtain necessary goods or services without having to make large, upfront payments.
How Does EMI Work?
The financial institution adds interest to the principal when approving a loan to determine the total amount owed. Fixed EMIs are distributed over the repayment period as a result of dividing this amount by the number of installments (tenure). Unless the interest rate is floating, the borrower’s monthly outflow stays the same for the duration of the loan.
Two Ways Interest is Calculated on EMIs
Either the Reducing Balance Method or the Flat Interest Method are commonly used to calculate interest on EMIs:
- The flat interest method computes interest on the entire principal over the course of the term.
- Reducing Balance Method: Following each repayment, interest is computed on the remaining principal.
Flat Interest Method
The formula is:

Where interest is calculated

This method usually results in higher overall interest payments.
Reducing Balance Method
The formula is

Where:
- PP = Principal amount
- RR = Monthly interest rate (annual rate divided by 12)
- NN = Number of EMIs
Interest is charged on the outstanding principal post each payment, resulting in lower total interest outflow as the principal decreases over time.
Types of EMIs
Two EMI payment plans are typically available for loans:
- EMI in Arrears (Standard EMI): Principal and interest are included in each payment, which is made at the conclusion of each period.
- EMI in Advance: Just the principal is paid in the first EMI, which is made at loan disbursement. Since the upfront payment is subtracted and subsequent EMIs comprise both principal and interest, this lowers the disbursed principal.

Components of EMI
Each EMI has two key parts:
- Principal: Portion of the loan amount repaid.
- Interest: Cost paid for borrowing funds.
Over time, the interest component in each EMI decreases, while the principal component increases.
Factors Affecting EMI Amount
How EMI Helps in Financial Planning
By providing predictability, EMIs assist borrowers in creating monthly spending plans and preventing unforeseen financial strain. Frequent payments raise credit scores and foster sound financial practices, which makes it simpler to obtain credit in the future.

How to Buy Products on Easy EMIs
Many retailers and lenders offer products on EMIs, either with no-cost (zero interest) EMI options or with standard interest rates. Products can be bought using credit cards, EMI cards, or via lender agreements. Upfront eligibility checks, documentation, and agreement on tenure/interest rate are required.
