What is an EMI?
EMI stands for Equated Monthly Instalment — the fixed amount you repay to a lender every month until a loan is fully paid off. Each EMI covers part of the interest and part of the principal. In the early months most of the payment goes towards interest; as the outstanding balance shrinks, more of each EMI chips away at the principal. Knowing your EMI before you borrow helps you check the loan comfortably fits your monthly budget.
How to use the EMI calculator
- Enter the loan amount you plan to borrow.
- Add the annual interest rate offered by your lender.
- Set the tenure in years (or switch to months).
- Your EMI, total interest and total payment update instantly.
How is EMI calculated?
EMI uses the standard reducing-balance formula: EMI = P × r × (1+r)ⁿ ÷ ((1+r)ⁿ − 1), where P is the principal, r is the monthly interest rate (annual rate ÷ 12 ÷ 100) and n is the number of monthly instalments.
A quick example
Borrow ₹10,00,000 at 9% per year for 20 years and the EMI works out to roughly ₹9,000 a month. Over the full term you’d repay around ₹21.6 lakh — meaning about ₹11.6 lakh of that is interest. Shorten the tenure to 10 years and the monthly EMI rises, but the total interest falls sharply. Try both in the calculator to see the trade-off for your own numbers.
Tips before you take a loan
- Balance EMI and tenure: a longer tenure means a smaller EMI but far more interest overall.
- Watch the rate: even a 0.5% difference in interest adds up over a long loan.
- Keep a buffer: a common rule is to keep total EMIs below about 40% of your monthly income.
- Prepay when you can: paying extra early reduces the principal and saves interest.
Frequently asked questions
Does a higher tenure reduce my EMI? Yes — a longer tenure lowers the monthly EMI but increases the total interest you pay overall.
Does it work for home, car and personal loans? Yes — the EMI formula is the same for any reducing-balance loan; just enter that loan’s amount, rate and tenure.
