How the EMI is worked out
An EMI is a fixed monthly payment that covers the interest for that month and repays part of the loan. It depends on three things: the amount, the interest rate and the tenure. The standard formula is EMI = P x r x (1+r)^n divided by ((1+r)^n - 1), where P is the loan amount, r is the monthly rate (the yearly rate divided by 12 and then by 100) and n is the number of monthly instalments. Home loans, personal loans, business term loans and loans against property all use the same formula; only the numbers change.
Why early EMIs are mostly interest
Each month, interest is charged on what you still owe. At the start you owe the most, so most of the EMI goes to interest and only a little reduces the loan. As the balance falls, the interest part shrinks and more of each EMI repays the loan. The year-by-year table in this calculator shows how that shifts. It is also why prepaying early in a loan saves the most.
How tenure changes what you pay
A longer tenure lowers the EMI but adds months of interest, so the total you repay rises. A shorter tenure raises the EMI and cuts the total. Try the same loan over two tenures and compare the total repayment, not only the EMI. The right tenure is the shortest one whose EMI you could still pay in a difficult month.
If your rate is floating
On a floating-rate loan, the rate can move when the lender's benchmark changes. Many lenders keep the EMI the same and change the tenure instead, which can quietly add months or years. Use the "if the rate changes" check to see both effects with a rise and a fall of your own choosing. Our Home Loan page explains how rate resets work.
Fees and the Key Fact Statement
The EMI shows only part of the cost. Processing fees and other charges are often deducted from the loan, so you receive less than you borrow while repaying the full amount. Add them in the fees check to see the real cost. Before you accept any loan, ask for the Key Fact Statement: it shows the lender's annual cost figure including fees, which is the fairest way to compare two offers.
Frequently asked questions
How is a home loan EMI calculated?
With the same formula as any other loan: the amount, the monthly rate and the number of months. Because home loans run for many years, the total interest can come close to the amount borrowed, which is why the tenure and prepayments matter so much. Enter your numbers above to see the EMI, the total and the year-by-year balance.
Can I use this for a balance transfer or a top-up?
Yes. For a top-up, work out the EMI on the extra amount and add it to the EMI you already pay. For a balance transfer, work out the new EMI on what you still owe at the new rate over the tenure you have left, then compare the total with what you would pay by staying, adding the switching charges in the fees check. Our Personal Loan Balance Transfer page and Home Loan Balance Transfer page walk through the full comparison.
Does it work for home loans, personal loans and loans against property?
Yes. All of them use the same EMI formula. What differs is the rate, the tenure lenders allow and the charges, so use the figures from the offer you are considering.
What is the difference between a flat rate and a reducing-balance rate?
This calculator uses a reducing-balance rate, where interest is charged only on what you still owe, as most bank and NBFC loans do. A flat rate charges interest on the full original amount for the whole tenure, so the same headline rate costs much more. If an offer quotes a flat rate, ask for the equivalent reducing-balance rate and the Key Fact Statement.
Why might my lender's EMI differ slightly?
Lenders may round differently, count days rather than months, charge interest for the days before the first EMI, or add insurance to the loan. Small differences are normal. A large one is worth asking about, and the repayment schedule in the sanction letter is the figure that counts.
