EMI Calculator for beginners — start here

EMI stands for equated monthly instalment: the fixed amount you pay every month until a loan is fully repaid. “Equated” means equal — the amount does not change from month to month, even though the split between interest and principal quietly shifts underneath. If you have never taken a loan, that single idea is enough to start.

The three numbers you need

First, the loan amount: what you actually borrow. Second, the annual interest rate, written as a percentage — 9%, 10.5%, whatever the lender quotes. Third, the tenure: how many years you will take to repay. Type those three into the calculator and it returns your EMI, the total interest and the total payment. Nothing else is required, and there is no sign-up.

Worked example

Borrow ₹7,50,000 at 10.5% a year for 10 years. The EMI is ₹10,120 a month, the total payment is ₹12,14,415 and the total interest is ₹4,64,415. Notice that the interest is more than half the amount borrowed — that is normal for a 10-year loan, and it is the number to compare when you shop between lenders.

What to do next

Try the same loan at a shorter and a longer tenure. A shorter tenure raises the monthly payment but cuts the total interest; a longer one does the opposite. Pick the shortest tenure whose EMI still leaves room for your other expenses, and never choose a loan by the EMI alone — always look at the total interest beside it.

Frequently asked questions

Do I need to know anything else about the loan?

For an estimate, no. The exact schedule also depends on fees and the lender’s rounding, but the three numbers above get you within a small margin.

What is principal?

The amount you borrowed, as opposed to the interest charged for borrowing it. Each EMI pays some interest first, and the rest reduces the principal.

Can the EMI change during the loan?

Yes, if you have a floating rate and the lender revises it. The calculator shows the EMI at today’s rate, so re-run it if your rate changes.
