EMI stands for Equated Monthly Installment. It is a fixed payment amount made by a borrower to a lender at a specified date each calendar month. EMIs are applied to both interest and principal each month so that over a specified number of years, the loan is paid off in full.
Most modern loans use the "Reducing Balance" method. Interest is calculated on the outstanding principal at the end of each month. As you pay back the principal, the interest component of your EMI decreases over time.
No, this calculator focuses on the interest and principal. Banks often charge a 1-2% processing fee. You should subtract this fee from your disbursed amount or add it to your total cost calculation manually.
Yes! This calculator is universal. Whether it's a small personal loan, a car loan, or a business credit line, the math remains the same. Just ensure you enter the correct annual interest rate.
A shorter tenure means higher monthly EMIs but much lower total interest paid. A longer tenure makes the monthly payment more affordable but significantly increases the total interest cost over the life of the loan.
