EMI Calculator

This is the single most expensive misunderstanding in consumer borrowing, and it is worth settling before anything else on this page. When a lender quotes a rate, they are using one of two completely different methods, and the number sounds identical either way.

Reducing balancecharges interest only on what you still owe. Every EMI cuts the outstanding principal, so next month's interest is calculated on a smaller amount. This is what home loans, car loans, and bank personal loans use, and it is what this calculator computes.

Flat rate charges interest on the original amount for the entire tenure, ignoring everything you have already repaid. It shows up in some consumer-durable finance, dealer schemes, and informal lending.

Put real numbers on it. Borrow ₹5,00,000 for 5 years at “10%”:

The flat-rate version costs ₹1,12,589 more on the same principal at the same headline rate. Worked backwards, that flat 10% is equivalent to roughly 17.27% on a reducing-balance basis — not far off double.

So before you trust any EMI figure, ask the lender which method the quote uses. If the answer is flat, or if nobody will say clearly, work out the EMI they are proposing and enter it into a reducing-balance comparison. A useful shortcut: for a given EMI and tenure, if the total repayment is far above what this calculator produces at the quoted rate, you are being quoted flat.

Borrowers are often startled a year into a loan to find the outstanding amount has hardly moved. Nothing is wrong. It is arithmetic, and the amortisation table above shows it month by month.

Take the default values on this page — ₹10,00,000 at 9.5% over 120 months. The EMI is ₹12,940. In month one, ₹7,917 of that is interest and only ₹5,023 reduces the principal. Interest is charged on the full ₹10,00,000 because that is genuinely what you owe on day one.

Each month the balance is slightly smaller, so slightly less of the EMI goes to interest and slightly more to principal. The point where the principal share finally overtakes the interest share is the loan's turning point — for this example it arrives in month 34, nearly three years in. The panel above computes that month for whatever figures you enter.

This front-loading is not a penalty or a trick, and the total is the same as any other correct reducing-balance schedule. But it has two practical consequences worth internalising: a prepayment made early removes far more future interest than the same amount paid late, and selling an asset in the first few years of a long loan often means you have built very little equity in it.

A longer tenure lowers the EMI, which is why it is so often suggested when a loan looks unaffordable. What it does to the total is less visible. Here is ₹50,00,000 at 9.5%, computed at four tenures:

Stretching from 15 to 30 years cuts the EMI by ₹10,168 a month — meaningful relief. It also raises total interest from ₹43.98 lakh to ₹1.01 crore. You pay ₹57 lakh more to borrow the same ₹50 lakh, and at 30 years the interest exceeds the principal by more than double.

The returns also taper sharply. Going 15 → 20 years saves ₹5,604 per month. Going 25 → 30 years saves only ₹1,642 while adding roughly ₹20 lakh in interest. Past a point, extra years buy very little breathing room at a steep price.

None of which makes a long tenure wrong. A lower EMI can be the difference between a manageable loan and a default, and lenders assess eligibility on EMI relative to income, so a longer tenure may be what gets a loan sanctioned at all. The sound approach is to take the tenure you can service safely, then repay faster than required — which is where prepayment matters.

When you make a lump-sum prepayment, the lender will usually ask which you want. The choice matters more than it sounds.

Keep the EMI, cut the tenure. Your monthly outgo stays the same and the loan simply ends sooner. Because the removed months are the ones at the end, and because the balance is lower for every remaining month, this saves the most interest.

Keep the tenure, cut the EMI. Your monthly commitment drops immediately. You still save interest, but far less, since you remain in debt for the original number of months. This is the right choice when cash flow is tight — a smaller EMI is real protection against a missed payment.

The panel above quantifies the upper bound for your own figures: it shows the interest you would avoid by clearing the loan entirely at the halfway point. For the default ₹10 lakh example, roughly a quarter of all interest sits in the second half of the tenure, even though the balance is much smaller by then.

On charges, the rules changed recently and in borrowers' favour. Under the RBI (Pre-payment Charges on Loans) Directions, 2025 — effective for loans sanctioned or renewed on or after 1 January 2026 — lenders cannot levy prepayment or foreclosure charges on floating-rate loans taken by individuals for non-business purposes, regardless of loan amount or co-borrowers. That covers housing, education, and personal loans. Fixed-rate loans are not covered, and may still carry charges set out in your agreement, so check which type you hold before assuming prepayment is free.

This calculator assumes a fixed rate for the whole tenure. Most long-tenure loans in India are floating, linked to an external benchmark, so the rate you enter today is a snapshot rather than a promise. A 30-year schedule computed at one rate is a planning estimate, not a contract.

When the benchmark rises, a lender can respond by raising your EMI, extending your tenure, or both. Tenure extension is common because the EMI stays comfortingly unchanged — but it silently moves you down the tenure table above, where total interest is far higher. It is the same trade as choosing a longer tenure at the outset, just made without a conversation.

RBI's August 2023 circular on resetting floating interest rates on EMI-based personal loans gives borrowers rights here that are worth knowing. At the time of a reset, you must be offered the choice to increase the EMI, extend the tenure, or combine the two; the option to switch to a fixed rate as per the lender's board-approved policy, which may carry a conversion fee; and the ability to prepay in part or full at any point during the tenure. Lenders must also disclose, at sanction, how a benchmark change could affect your EMI and tenure.

Practically: after any rate revision, re-run your loan here with the new rate and your remaining months. If your tenure was quietly extended, you will see exactly what that decision costs, and you can ask for a higher EMI instead if you can afford it.

Lenders assess how much of your income is already committed to debt. A widely used rule of thumb is that total EMIs across all loans should stay under roughly 40% of net monthly income, though the threshold each lender applies varies with income level, job stability, credit score, and the type of loan.

That test protects the lender. Your own test should be stricter, because a sanctioned loan is not the same as a comfortable one. Before committing, work out whether the EMI still leaves room for the expenses that a spreadsheet forgets: annual insurance premiums, school fees, maintenance on the asset you just bought, and an emergency fund you can reach without borrowing again. A common way people get into difficulty is passing the bank's 40% test with nothing left over for the year's surprises.

If you already have other loans, add every EMI together rather than looking at the new one alone — the loan pressure calculator works out that combined share of income. And if the money is going toward an investment-versus-prepayment decision, comparing the loan interest you would avoid against the returns you might earn is easier alongside the SIP calculator.

Figures on this page are estimates from the reducing-balance formula and the values you enter, computed in your browser. Your lender's sanction letter is the authoritative number: rounding conventions, the exact day of disbursal, and fees will shift the EMI slightly. Nothing here is financial advice, and it does not indicate eligibility or approval — for a decision this size, read the sanction letter and the loan agreement, and ask the lender to explain anything the documents leave vague.
