EMI Calculator Guide: How Loan EMI Works in India

Learn how loan EMI is calculated in India, what affects your monthly payment, and how to compare total interest before taking a loan.

What is EMI?

EMI means Equated Monthly Instalment. It is the scheduled monthly payment used to repay a loan over a selected tenure. An EMI generally contains both interest and principal.

How is EMI calculated?

For a standard reducing-balance loan, EMI can be estimated using the principal, monthly interest rate and number of monthly payments. The formula is:

EMI = P × r × (1+r)ⁿ ÷ ((1+r)ⁿ − 1)

Here, P is the loan principal, r is the monthly interest rate and n is the total number of monthly instalments. If the interest rate is zero, EMI is simply principal divided by the number of payments.

What changes your EMI?

• Higher loan amount: usually increases EMI.
• Higher interest rate: increases the interest component and usually the EMI.
• Longer tenure: can reduce monthly EMI but may increase total interest.
• Prepayments: can reduce outstanding principal and future interest, subject to lender terms.

EMI vs total repayment

A low EMI does not automatically mean a cheaper loan. Always compare the total amount repaid and total interest along with the monthly payment.
