Loan / EMI Calculator
Calculate monthly installments with interest rates, tenure, and amortization breakdown.
The Equated Monthly Installment (EMI) is calculated using the standard reducing balance formula: EMI = P x r x (1+r)^n / ((1+r)^n - 1), where P is the principal loan amount, r is the monthly interest rate (annual rate / 12 / 100), and n is the total number of monthly installments.
This formula ensures that each monthly payment remains constant throughout the loan tenure, while the proportion of principal and interest within each payment changes over time. Early payments consist primarily of interest, while later payments contribute more toward the principal balance. This is known as the amortization effect.
Use this calculator to compare different loan offers, plan your monthly budget, and understand the total cost of borrowing. A lower interest rate or longer tenure reduces the EMI but increases the total interest paid. The interest-to-principal ratio helps you understand how much extra you are paying beyond the borrowed amount.
What Is an EMI and How Is It Calculated?
EMI stands for Equated Monthly Installment. It is the fixed amount you pay to a lender every month until the loan is fully repaid. Every EMI payment has two components: a portion that goes toward the principal (the original amount you borrowed) and a portion that covers the interest charged by the lender.
The EMI formula is: EMI = P × r × (1 + r)ⁿ / ((1 + r)ⁿ - 1), where P is the principal loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly installments. This calculator handles that math instantly so you can compare different loan scenarios in seconds.
How to Use This EMI Calculator
- Enter the loan amount — the total amount you want to borrow.
- Enter the annual interest rate offered by your bank or lender.
- Enter the loan tenure in months or years.
- The calculator instantly shows your monthly EMI, total interest payable, and total amount paid.
- The amortization schedule shows how much goes to principal vs interest each month.
Tips to Reduce Your Total Interest Payment
- Shorter tenure: A 3-year loan has a higher monthly EMI but you pay far less total interest than a 7-year loan.
- Larger down payment: Reducing the principal reduces interest calculated on the whole amount.
- Prepayments: Paying extra toward the principal in early months has an outsized impact on reducing total interest.
- Compare lenders: Even a 0.5% difference in interest rate makes a significant difference over a long loan term.
