Online EMI Calculator
An Equated Monthly Installment (EMI) is a fixed amount that a borrower pays to a lender on a specific date each month. EMIs are commonly used for home loans, car loans, and personal loans. The EMI amount is calculated based on the principal loan amount, the interest rate, and the loan tenure. A higher principal amount, a higher interest rate, or a longer tenure will result in a higher EMI. Conversely, a lower principal amount, a lower interest rate, or a shorter tenure will result in a lower EMI. Understanding your EMI is crucial for budgeting and financial planning. Use this calculator to easily estimate your monthly loan payments.
