EMI Calculator

EMI stands for Equated Monthly Instalment— one fixed amount paid to a lender on the same date each month until the loan is repaid. “Equated” is the important word: the amount is deliberately levelled so that every payment is identical, which is what makes a loan budgetable.

Each instalment contains two things:

• Intereston the balance still outstanding — the lender’s charge for the money you have not yet returned.
• Principal repayment — the part that actually reduces what you owe.

The total stays constant, but the split does not. In the first month the balance is at its highest, so interest takes most of the payment. As the balance falls the interest charged on it falls too, and since the instalment is fixed, the principal share grows to fill the gap. By the final months almost the entire payment is principal.

This is reducing-balance interest, and it is the standard method for Indian retail lending. It is worth distinguishing from flat-rate interest, occasionally quoted on small consumer loans, where interest is charged on the original amount for the whole term regardless of how much has been repaid. A flat rate always costs substantially more than a reducing-balance rate of the same number.

Three inputs determine the instalment, and nothing else does.

• Loan principal (P) — the amount borrowed. The EMI is exactly proportional to it: double the loan and the instalment doubles.
• Monthly interest rate (r) — the annual rate divided by 12 and then by 100. An advertised 9% a year is 0.0075 a month.
• Number of payments (n) — the tenure in months. Five years is 60 payments, twenty years is 240.

The calculation solves a single question: what constant monthly payment, made n times, brings the outstanding balance to exactly zero on the last one? Too small and the loan never clears; too large and it clears early. There is precisely one answer, and the formula below computes it directly.

Note what is notan input. Your income, credit score, employer and the lender’s policies determine the rate and the amount you are offered — but once those are fixed, they play no further part. The arithmetic is identical for every borrower and every lender.

• P — principal, the amount borrowed
• r — monthly interest rate as a decimal, so annual rate ÷ 12 ÷ 100
• n — total number of monthly payments

Worked through

Take ₹1,00,000 borrowed at 10% a year for 12 months. The monthly rate is 10 ÷ 12 ÷ 100 = 0.008333. Then (1.008333)^12 = 1.104713, and:

Twelve payments of ₹8,792 come to ₹1,05,499, of which ₹5,499 is interest.

The zero-interest case

When the rate is genuinely zero the formula breaks down — it divides by r, and r is zero. The instalment is then simply:

This calculator switches to that automatically. Be sceptical of zero-interest offers, though: the cost usually reappears as a processing fee, or as a cash discount you forgo by not paying up front. Enter that fee in the charges panel to see what the credit actually costs.

Read the first and last rows together. Going from 10 years to 30 cuts the instalment from ₹61,993 to ₹38,446 — a 38% reduction, and a very real difference to a monthly budget. The same move raises the interest from ₹24,39,141 to ₹88,40,443, which is more than three and a half times as much.

Neither column is the right answer on its own. A tenure you cannot service is not prudent, and stretching a loan to make it affordable is a legitimate choice. The mistake is stretching it without noticing the second column — which is exactly what the tenure table in the calculator exists to prevent.

Each percentage point adds roughly ₹3,215 to the monthly instalment on this loan, and several lakh to the total. That is the arithmetic case for spending an afternoon comparing lenders: half a percentage point, negotiated once, is worth more than most of the other economies available to a borrower.

A home loan is an ordinary amortising loan, so this calculator handles one exactly. What makes it feel different is scale: the principal is large, the tenure runs 15 to 30 years, and the two together produce an interest bill unlike anything else most people borrow.

At an assumed 8.5% over 20 years, ₹50 lakh gives an EMI of ₹43,391 and total interest of ₹54,13,879 — you repay ₹1,04,13,879 for a ₹50 lakh house. Over 30 years the interest passes the principal outright.

Three things worth doing before committing:

• Look at the crossover month in the schedule. On that 20-year loan, more than half of every instalment is interest until month 143 of 240.
• Check whether the rate is floating. Most Indian home loans are, and lenders usually absorb a rate change by extending the tenure rather than raising the EMI — so the monthly figure holds while the loan quietly gets longer.
• Budget for the costs that are not the loan: stamp duty, registration, the processing fee and insurance. None of them is in any EMI.

If you have not settled on an amount yet, work out what you can service first — the Loan Eligibility Calculator starts from income rather than from a figure, and answers the question in the other direction.

A personal loan is unsecured — there is no asset behind it — so the lender prices in that risk, and the rate lands well above secured borrowing. Tenures are correspondingly short, usually one to five years.

At an assumed 12% over 5 years, ₹5 lakh gives an EMI of ₹11,122 with ₹1,67,333 in interest — a third of the amount borrowed, over a fairly short loan.

Pay particular attention to the processing fee here. On a five-year home loan a 1% fee is a rounding error against the interest; on a two-year personal loan it is a meaningful share of the total cost, and it is frequently deducted from the amount disbursed rather than invoiced separately. The charges panel in the calculator keeps it visible instead of folding it into the instalment where it would disappear.

Car loans are secured against the vehicle, so rates sit between home and personal lending. Tenures run three to seven years — lenders are reluctant to let a loan outlive the asset securing it, and a car depreciates faster than a house.

At an assumed 9% over 7 years, ₹8 lakh gives an EMI of ₹12,871 and ₹2,81,186 in interest.

Two things catch people out. First, lenders typically finance the on-road price less your down payment, and the on-road price includes registration, insurance and taxes — noticeably more than the ex-showroom figure in the advertisement. Enter the amount you are actually borrowing, not the sticker price. Second, a longer car loan can leave you owing more than the vehicle is worth for much of the term, which matters if you plan to sell before the end.

For the repayment phase, this calculator works normally: at an assumed 9% over 10 years, ₹20 lakh gives an EMI of ₹25,335 with ₹10,40,219 in interest.

There is one important thing it does not model. Education loans normally carry a moratorium — the course duration plus a further six to twelve months — during which no EMI, or interest only, is due. Interest generally continues to accrue through that period and is capitalised: added to the outstanding balance. So repayment begins on a figure larger than the amount sanctioned.

To approximate that here, work out the accrued interest over the moratorium and add it to the principal before calculating. A ₹20 lakh loan with four years of accruing interest at 9% starts repayment nearer ₹28 lakh than ₹20 lakh — a difference too large to ignore. This is a general-purpose calculator and does not apply lender-specific rules unless you enter them yourself.

The single most useful idea on this page: a lower EMI does not mean a cheaper loan. It usually means a more expensive one.

Two offers on ₹50 lakh at the same assumed 8.5%. The first has an EMI of ₹49,237 over 15 years. The second has an EMI of ₹40,261 over 25 years — over ₹8,976 a month cheaper, which is what the eye goes to.

But the first costs ₹38,62,656 in interest and the second costs ₹70,78,406 — a difference of ₹32,15,750. The cheaper-looking loan is substantially the more expensive one.

This is why lenders and brokers lead with the monthly figure. It is the number that feels like the price, and it is not the price. Compare offers on total repayment, then check that the EMI is one you can actually service.

Five things genuinely move the number, roughly in order of effect.

• Choose the shortest tenure you can comfortably service. Not the shortest available — one you cannot sustain is worse than a longer loan you can. But every year removed cuts the interest bill sharply, and the tenure table shows exactly how much.
• Compare rates properly before signing. Half a percentage point on a twenty-year loan is worth several lakh, and the rate is fixed at the outset. This is the one decision with the largest payoff for the least effort.
• Prepay early, where your agreement permits it. Interest is charged on the outstanding balance, so a lump sum in year three removes far more interest than the same sum in year fifteen. In India, floating-rate home loans to individuals generally cannot carry a prepayment penalty — check your own terms.
• Increase the EMI when you can afford to. Many lenders allow a step-up. Raising the instalment shortens the loan, and shortening the loan is what removes the interest.
• Borrow less. A larger down payment reduces the principal, and the interest is proportional to it. Not always possible, but it is the most direct lever of the five.

Two cautions. Do not empty an emergency fund to prepay a loan — losing the buffer is a worse risk than the interest saved. And a balance transfer to a lower rate is only worth it after the processing fee and legal charges on the new loan are netted off; run both through this calculator with the fees included before moving.

An amortisation schedule is the loan written out payment by payment. For every instalment it shows four things:

• EMI — the amount paid, identical every month
• Interest— that month’s charge on the outstanding balance
• Principal — the remainder, which reduces the debt
• Balance — what is still owed afterwards

The shape is the point. On ₹50 lakh at an assumed 8.5% over 20 years, the first instalment of ₹43,391 is about ₹35,417 interest and only ₹7,974 principal. The last is almost entirely principal. Interest does not exceed principal for the final time until month 143 of 240 — meaning that for nearly 60% of the loan, most of what you pay is the cost of borrowing rather than the borrowing itself.

That is also the arithmetic behind prepayment. A lump sum in year two removes principal that would otherwise have accrued interest for eighteen more years; the same sum in year eighteen removes almost nothing, because that principal was about to be repaid anyway.

The schedule in this tool is generated at full precision and closes at exactly zero — the principal column adds up to the loan you entered, to the paisa.

Fixed

The rate is agreed and does not change for the fixed period. The EMI is known in advance for that time, which makes budgeting straightforward. Lenders normally price fixed rates above the equivalent floating rate, because they are absorbing the risk that rates rise. Some “fixed” products are only fixed for an initial few years and then convert — worth reading carefully.

Floating

The rate tracks a benchmark and moves with it. Most Indian home loans are floating, and since 2019 most retail floating loans have been linked to an external benchmark such as the repo rate rather than an internal one.

The behaviour that surprises people: when a floating rate changes, lenders usually keep the EMI where it is and adjust the tenure instead. A rate rise therefore appears as nothing at all on your monthly statement while the loan quietly extends — sometimes by years. Ask your lender which they adjust, and check your outstanding tenure after any rate movement.

This calculator models a single constant rate throughout. For a floating loan, treat the result as the position at today’s rate, and try a point either side in the rate comparison table to see the range you are exposed to.

• Confusing annual and monthly rates. The formula needs the monthly rate — the annual figure divided by 12 and then by 100. Putting 9 straight into r instead of 0.0075 produces an EMI wildly higher than reality.
• Confusing months and years. n is the number of monthly payments. A 20-year loan is 240, not 20. This one is easy to spot, because the answer is absurd.
• Judging a loan by the EMI alone.The instalment is one month’s payment. Compare the total repayment, which is that figure multiplied by the number of payments.
• Ignoring fees. Processing fees, insurance, documentation and legal charges never appear in an EMI and are often deducted from the amount disbursed, so you receive less than you borrowed while repaying the full amount.
• Using the wrong loan amount. For a car, the on-road price less the down payment; for a house, the sanctioned amount rather than the property price. Stamp duty and registration are usually not financed.
• Treating a calculator result as a quote.The arithmetic here is exact, but a lender’s figure also reflects their rounding, the disbursal date, broken-period interest and any charges bundled into the loan. Differences of a few rupees are normal; large ones mean the terms differ from what you entered.
• Comparing a flat rate with a reducing-balance rate.A quoted “8% flat” is far more expensive than 8% reducing balance, because flat interest is charged on the original amount for the whole term regardless of repayment. Always establish which is being quoted.
