EMI Calculator
Calculate your loan EMI and view the full amortization schedule.
About this tool
An EMI (Equated Monthly Installment) calculator helps you understand the true cost of borrowing by breaking down loan repayments into predictable monthly amounts. Whether you're planning a home purchase, financing a car, or taking a personal loan, knowing your exact monthly payment and total interest burden upfront allows you to budget confidently and compare loan options effectively.
Using this calculator is straightforward: enter your loan amount, annual interest rate, and desired loan tenure in years, then instantly see your monthly EMI and a complete amortization schedule showing exactly how much of each payment goes toward interest versus principal. The detailed breakdown reveals how your repayment changes month-by-month, helping you track your loan's progress and understand the impact of different interest rates and loan terms.
This tool is invaluable for anyone evaluating loans—borrowers can use it to negotiate better terms with lenders, financial planners can present repayment scenarios to clients, and students learning about loans and debt can see the mathematics in action. The visual amortization table makes it easy to spot when you'll pay off your loan and how much total interest you'll owe, making financial planning transparent and accessible.
