EMI Calculator

How to calculate your EMI

1. Enter the loan amount — for example 500,000 for a personal loan or 5,000,000 for a home loan.
2. Enter the annual interest rate the bank quoted you, for example 12%.
3. Enter the term in years — for example 5 years.
4. Your EMI (equated monthly instalment) appears instantly, with the total interest and total repayment.
5. Change any number to compare: a shorter term, a lower rate, or a smaller loan — and see the EMI change in real time.

How EMI works

EMI stands for Equated Monthly Instalment: the fixed amount you pay every month until the loan is finished. It never changes during a fixed-rate loan, but the split inside it does. Each payment is part interest (on the amount you still owe) and part principal (paying the loan itself down). Early on, most of your payment is interest, because the amount owed is large; near the end, most of it is principal.

The formula is: monthly payment = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments. Worked example: borrow 500,000 at 12% per year for 5 years. The monthly rate is 1%, and there are 60 payments. The EMI comes to about 11,122 per month. Over 60 months you repay about 667,320 in total, so the total interest is about 167,320. Stretch the same loan to 10 years and the EMI falls to about 7,174 — but the total interest rises to about 360,880. A smaller monthly payment is not a cheaper loan.

Common uses

Home loans are the biggest use: before you commit to 15 or 20 years of payments, an EMI calculator shows you exactly what each month will cost, and how much extra a 1% higher rate adds over the whole term. Car loans and personal loans are the same idea on a shorter scale — a 3-year car loan and a 5-year car loan can differ by tens of thousands in total interest, even when the monthly payments look close.

People also use it to compare bank offers: two banks quoting 12% and 13% look almost the same, but on a 5,000,000 home loan over 20 years the difference is hundreds of thousands of rupees. And it answers the affordability question directly — as a rule of thumb, keep your total EMIs under 30–40% of your monthly income, so one bad month does not break the budget.

Tips

A shorter term is almost always cheaper in total, even though the monthly payment is higher: on the 500,000 example above, 5 years costs about 167,000 in interest while 10 years costs about 361,000 — more than double, for the same loan. If you can afford the higher EMI, take the shorter term. And check the fine print before you sign: processing fees, insurance and prepayment charges are not in the EMI, and a bank that quotes a low rate with high fees can cost more than a bank with a slightly higher rate and no fees.

Remember this calculator gives estimates, not a loan offer. Your real EMI depends on the bank's final rate, the exact tenure, and your credit profile. Always confirm the final EMI, the total repayment and any extra charges with the lender in writing before you sign anything.
