Whether you're planning to buy a home, a car, or need a personal loan, understanding your monthly repayment obligation before signing any loan agreement is critical. This free online EMI calculator instantly computes your monthly payment, total interest outgo, and provides a complete year-wise amortization schedule — helping you compare loan offers and choose the most affordable option.
What is EMI Calculator — Loan Equated Monthly Installment?
An EMI is the fixed monthly amount a borrower pays to a lender to repay a loan over a specified tenure. Each EMI consists of two components: the principal repayment and the interest charge. In the early months of a loan, a larger portion of the EMI goes toward interest, while in later months, more goes toward principal repayment. This is called an amortizing loan structure. EMIs are computed using the PMT (Present Value of Annuity) formula and are the standard repayment structure for home loans, car loans, personal loans, and education loans in India.
Formula Used
The EMI formula calculates the fixed monthly payment that will fully amortize a loan over its tenure at a given interest rate. The monthly interest rate (r) is obtained by dividing the annual rate by 12.
EMI = P × r × (1 + r)ⁿ / [(1 + r)ⁿ − 1]
Where: P = Principal Loan Amount, r = Monthly Interest Rate (Annual Rate / 12 / 100), n = Loan Tenure in MonthsHow to Use This Calculator — Step by Step
- 1
Enter the Principal Loan Amount — the total amount you wish to borrow (e.g., ₹50,00,000 for a home loan).
- 2
Enter the Annual Interest Rate (%) — the rate quoted by your bank (e.g., 8.5% for current SBI home loan rates).
- 3
Enter the Loan Tenure in Years — the total repayment period (e.g., 20 years for a home loan).
- 4
The calculator instantly shows your Monthly EMI, Total Interest Payable, and Total Amount Payable.
- 5
Scroll down to the Amortization Schedule to see year-by-year principal and interest breakdown.
Real-Life Example
Rahul from Mumbai wants to buy a home worth ₹75,00,000. He has a ₹25,00,000 down payment and takes a home loan of ₹50,00,000 at 8.5% annual interest for 20 years. Using the EMI calculator: Monthly EMI = ₹43,391. Total Amount Paid = ₹1,04,13,840. Total Interest = ₹54,13,840. This means Rahul will pay over ₹54 lakhs as interest — more than the loan amount itself — which is why understanding the EMI and total cost before borrowing is crucial.
