Loan EMI Calculator — Home, Business & Personal Loans

Quick answer

EMI is the fixed monthly amount that repays a loan with interest over its tenure. It is worked out on the reducing balance: EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where P is the loan, r the monthly rate and n the number of months. For example, a ₹10 lakh loan at 9.5% a year for 5 years has an EMI of about ₹21,002, with total interest of about ₹2.60 lakh.

How to use this EMI calculator

The calculator has three fields. It works for home loans, business loans, personal loans, car loans and education loans — any loan repaid in equal monthly instalments on a reducing balance.

1. Loan amount — the principal you are borrowing, in rupees. Use the amount actually disbursed, not the property or vehicle price.
2. Interest rate (% per year) — the annual rate quoted by the lender. It starts at 9.5% and moves in steps of 0.05%, so you can enter rates like 8.35% or 10.75% exactly.
3. Tenure (years) — the repayment period. It starts at 5 years and moves in steps of half a year, so 2.5 years or 17.5 years also work. The calculator converts years to months (2.5 years becomes 30 instalments).

The result shows your monthly EMI, the number of instalments, the total interest you will pay over the loan, and the total payment (principal plus interest). Change any one field and the numbers update, which makes it easy to compare offers or tenures side by side.

The calculator assumes the rate stays the same for the whole tenure and that the first EMI is paid one month after disbursal. Real loans may differ slightly because of processing fees, broken-period interest or rate changes, which we explain below.

Comparing two loan offers

When two lenders quote different rates and fees, run each offer through the calculator separately with the same loan amount and tenure. Note the EMI and total interest for each, then add the processing fee and any other one-time charges to the total interest. The offer with the lower all-in cost is cheaper, even if its headline rate is slightly higher. For example, on a short loan a lower fee can outweigh a 0.25% rate difference, while on a 20-year home loan the rate almost always matters more.

The EMI formula explained

Every bank and housing finance company in India uses the same reducing-balance formula for standard EMI loans:

EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1)

• P = loan amount (principal)
• r = monthly interest rate = annual rate ÷ 12 ÷ 100
• n = number of monthly instalments = years × 12

Working it out step by step

Take a loan of ₹10,00,000 at 9.5% for 5 years.

1. Monthly rate r = 9.5 ÷ 12 ÷ 100 = 0.0079167
2. Number of instalments n = 5 × 12 = 60
3. (1 + r)^60 = about 1.6050
4. EMI = 10,00,000 × 0.0079167 × 1.6050 ÷ (1.6050 − 1) = about ₹21,002
5. Total payment = ₹21,002 × 60 = about ₹12,60,112
6. Total interest = ₹12,60,112 − ₹10,00,000 = about ₹2,60,112

The calculator does exactly this, without any rounding in between, and rounds only the final figures to the nearest rupee.

What "reducing balance" means

Each month, interest is charged only on the principal still outstanding. Your EMI first pays that month's interest, and whatever is left reduces the principal. As the principal falls, the interest part of each EMI falls and the principal part rises, even though the EMI itself stays the same.

In the example above, the first EMI of ₹21,002 has interest of ₹7,917 (₹10,00,000 × 0.0079167) and principal of ₹13,085. By the last year, almost all of each EMI goes to principal.

How your loan is repaid year by year

This repayment schedule for the same ₹10 lakh loan at 9.5% over 5 years shows how the interest share shrinks over time.

Over a 20-year home loan, this effect is far stronger. In the early years, most of every EMI goes towards interest. That is why prepaying early saves so much more than prepaying near the end.

Worked examples

All numbers below were worked out with the same formula the calculator uses. Type them in to check.

Example 1: A home loan of ₹50 lakh

Loan ₹50,00,000 at 8.5% for 20 years (240 instalments).

• Monthly EMI: about ₹43,391
• Total interest: about ₹54,13,879
• Total payment: about ₹1,04,13,879

Over 20 years, you pay more in interest than the amount you borrowed. In the first month alone, interest is about ₹35,417 and only about ₹7,974 goes to principal.

Example 2: A business term loan

A small manufacturer takes ₹20,00,000 at 12% for 3 years to buy a machine.

• Monthly EMI: about ₹66,429
• Total interest: about ₹3,91,430
• Total payment: about ₹23,91,430

Before committing, check that the machine's extra monthly cash flow comfortably covers ₹66,429, with room for slow months.

Example 3: A personal loan with a half-year tenure

Loan ₹5,00,000 at 14%. Compare 3 years with 2.5 years.

Paying about ₹2,760 more each month saves about ₹19,700 in interest.

Example 4: A car loan — 5 years or 7 years?

Loan ₹8,00,000 at 9%.

The longer tenure cuts the EMI by about ₹3,700 a month but adds about ₹84,800 to the total cost — for a vehicle that loses value every year.

Tenure vs EMI: the real trade-off

A longer tenure always means a lower EMI and a higher total cost. The calculator makes this visible. Here is the same ₹50 lakh home loan at 8.5% across three tenures:

Moving from 20 to 15 years raises the EMI by about ₹5,846 a month but saves about ₹15.5 lakh in interest. Moving from 20 to 25 years lowers the EMI by only about ₹3,130 but adds about ₹16.6 lakh of interest.

A practical approach

Many borrowers choose a longer tenure to keep the EMI comfortable and eligibility higher, then prepay whenever they have surplus money. This gives flexibility in tight months while still cutting interest. Make sure your loan allows prepayment without heavy charges before you plan this way.

The power of prepayment

Any extra amount you pay goes straight to reducing principal, so it stops all future interest on that amount. Early in a long loan, the effect is large.

Example: ₹2 lakh prepaid after one year

Take the ₹50 lakh, 8.5%, 20-year loan from Example 1. After 12 EMIs, the outstanding balance is about ₹49,00,489. You prepay ₹2,00,000 and keep paying the same EMI of ₹43,391.

• The loan now closes in about 219 months instead of 240 — about 21 months earlier.
• Total interest falls from about ₹54.14 lakh to about ₹46.84 lakh.
• Interest saved: about ₹7.29 lakh, from a one-time payment of ₹2 lakh.

Example: one extra EMI every year

Not everyone has a lump sum to prepay. A simple habit is to pay one extra EMI each year — for instance, from an annual bonus. On the same ₹50 lakh loan, paying an extra ₹43,391 at the end of every year:

• closes the loan in about 201 months instead of 240 — more than three years early;
• cuts total interest from about ₹54.14 lakh to about ₹43.85 lakh;
• saves about ₹10.29 lakh in interest.

The calculator shows the standard schedule; use it with these examples to see how much a regular habit can save on your own loan.

Reduce EMI or reduce tenure?

After a prepayment, most lenders let you either keep the EMI and shorten the tenure, or keep the tenure and lower the EMI. Keeping the EMI the same and shortening the tenure saves more interest. Lowering the EMI helps if your monthly budget is tight.

Prepayment charges

Under RBI rules, banks and finance companies cannot charge prepayment or foreclosure penalties on floating-rate loans taken by individuals for purposes other than business. For fixed-rate loans and business loans, charges may apply as per your loan agreement. Read the sanction letter, or check the RBI's directions on the RBI website, before you prepay.

Floating rates: what happens when the rate changes

Most home loans in India are on floating rates, usually linked to an external benchmark such as the RBI repo rate. When the benchmark moves, your rate moves too, after the reset period in your agreement. The calculator assumes one fixed rate, so use it to test "what if" scenarios.

Example: a 0.5% rate increase

On the ₹50 lakh, 20-year loan, if the rate goes from 8.5% to 9% at the start:

• EMI rises from about ₹43,391 to about ₹44,986 — an increase of about ₹1,595 a month; or
• If the lender keeps the EMI unchanged and extends the tenure instead, the loan runs for about 268 months instead of 240 — over two years longer.

Lenders often extend the tenure by default when rates rise, which can quietly add a lot of interest. RBI guidelines require lenders to tell you about rate resets and give you options, such as increasing the EMI, extending the tenure, or prepaying. If you can afford it, choosing a higher EMI usually costs less in the long run.

When rates fall

When the benchmark falls, check that your lender has actually passed on the cut. If your EMI stays the same, the tenure should come down. If you are on an older benchmark, it may be worth asking the lender about switching to the current one.

Working backwards: how much loan can your EMI support?

Most people know what they can pay each month better than what they should borrow. You can turn the EMI formula around to find the loan a given EMI supports:

Loan = EMI × ((1 + r)^n − 1) ÷ (r × (1 + r)^n)

Here r and n mean the same as before. You can also simply try different loan amounts in the calculator until the EMI matches your budget.

Example: a ₹30,000 monthly budget

Two things stand out. Stretching the tenure by five years adds only about ₹2.7 lakh of borrowing power, at a large interest cost. And a rate just 0.5% higher reduces what you can borrow by more than ₹1.2 lakh. When you plan a purchase, work out the loan from a comfortable EMI first, and then decide the down payment — not the other way round.

Leave room for the unexpected

Your EMI is a fixed commitment every month for years. Before you settle on a figure, think about job changes, business slowdowns, medical expenses and rate increases. A useful habit is to check the EMI at a rate 1% higher than the offer, and make sure you could still pay it.

Balance transfer: is switching lenders worth it?

If another lender offers a lower rate, you can move your outstanding loan to them. The calculator helps you judge whether the saving is worth the cost and effort.

Example

You have ₹40,00,000 outstanding with 15 years (180 months) left at 9.25%. Another lender offers 8.5% for the same remaining tenure.

• EMI at 9.25%: about ₹41,168
• EMI at 8.5%: about ₹39,390
• Monthly saving: about ₹1,778
• Saving over the remaining 15 years: about ₹3.20 lakh

Now subtract the costs of switching: the new lender's processing fee, legal and valuation charges, stamp duty on fresh documents where applicable, and any foreclosure charge on the old loan (generally nil for individual floating-rate home loans). If the net saving is still meaningful, the switch is worth considering.

Before switching, ask your current lender for a rate reduction. Many lenders allow existing borrowers to move to a lower rate for a small conversion fee, which can give most of the saving without changing banks.

Using the calculator for different kinds of loans

The formula is the same for every EMI loan, but each loan type has features worth knowing before you enter the numbers.

Home loans

For an under-construction property, the bank releases the loan in stages, and you usually pay only interest on the amount released (pre-EMI) until the full loan is disbursed. Use the calculator for the full EMI that starts after final disbursal. Pre-EMI interest is a separate cost on top.

Business term loans

Machinery and expansion loans are usually repaid in EMIs and fit the calculator directly. Cash credit and overdraft limits are different: you pay interest only on the amount actually used, and there is no fixed EMI, so this calculator does not apply to them.

Education loans

Many education loans have a moratorium during the course and for some time after it, during which interest keeps building up. When repayment starts, the EMI is calculated on the principal plus any interest not paid during the moratorium. Paying the interest during the moratorium, if you can, keeps the later EMI lower.

Personal and consumer loans

These are usually short, unsecured loans at higher rates. Check the rate is quoted on a reducing basis. "No-cost EMI" offers on products often have the interest built into the price or a discount you give up, so compare the total you pay with the cash price.

Gold loans

Many gold loans are repaid in one go at the end (bullet repayment) or with interest-only payments, not in EMIs. The calculator applies only if your gold loan is repaid in equal monthly instalments.

What happens if you miss an EMI

An EMI that bounces costs more than the instalment itself. It is worth knowing the consequences before you choose an EMI that stretches your budget.

• Charges. The lender will levy a bounce charge and penal charges as per your loan agreement. Under RBI rules, these must be a fixed penal charge and cannot be added to your interest rate or compounded.
• Credit report. Lenders report repayment history to credit bureaus. Even one late payment can lower your credit score and make future loans costlier or harder to get.
• Classification. If an instalment stays unpaid for more than 90 days, the loan is generally classified as a non-performing asset, and the lender can begin recovery action, including action against any security.

If you expect trouble paying, talk to your lender before the due date. Options such as a temporary change in EMI, a longer tenure or restructuring may be available, and it is always easier to arrange these before an account falls overdue. Keep enough balance in the EMI account a day or two before the debit date, since auto-debit mandates usually run early in the day.

Common mistakes when planning a loan

• Comparing flat and reducing rates directly. Some lenders quote a "flat" rate, where interest is charged on the full original loan for the whole tenure. On ₹10 lakh for 5 years, a 9.5% flat rate means ₹4,75,000 of interest (EMI about ₹24,583), against about ₹2,60,112 at 9.5% reducing. A flat rate is much costlier than it looks. This calculator works on reducing balance only.
• Looking only at the EMI. A low EMI from a very long tenure can double the total cost. Always look at total interest too.
• Ignoring fees. Processing fees, insurance bundled with the loan, and documentation charges add to the real cost but are not part of the EMI formula.
• Forgetting broken-period interest. If your loan is disbursed mid-month, the lender may charge interest for the days until the EMI cycle starts. This is a one-time extra amount.
• Taking an EMI that leaves no buffer. Lenders look at what share of your income goes to EMIs. Even if they approve, keep room for emergencies and rate increases.
• Not prepaying early. A prepayment in year 2 saves far more than the same amount in year 15.
• Letting the lender extend the tenure silently. When rates rise, check your loan statement for the remaining tenure, not just the EMI. A few extra years can add lakhs of interest without any change you would notice in your bank account.
• Entering the property or vehicle price as the loan amount. Enter only what you borrow after the down payment; otherwise the EMI and interest shown will be too high.

Tax benefits on loan repayments

Your EMI has two parts — interest and principal — and the tax treatment depends on the type of loan and the tax regime you choose.

The year-wise interest figure for your home loan comes from the lender's interest certificate, which you should collect every year. Our home loan tax benefit calculator shows how much tax the interest and principal save, and the income tax calculator tells you whether the old or new regime is better once these deductions are included.

Note: from tax year 2026-27, the Income-tax Act, 2025 renumbers these sections. This page and our tools use the familiar numbers (24(b), 80C, 80E) and the limits shown.

Joint home loans

If a house is bought jointly and both owners are co-borrowers paying the EMI, each can claim their own share of interest (up to ₹2 lakh each for a self-occupied house) and principal (within each person's ₹1.5 lakh Section 80C limit) under the old regime. Ownership share and repayment share should be clear in the documents and bank records, so each person's claim matches what they actually paid.

Interest on business loans in your books

For a business loan, only the interest part is an expense in your profit and loss account. The principal repaid reduces the loan liability in the balance sheet and is not an expense. Many small businesses get this wrong and show the full EMI as an expense, which understates profit and creates trouble in scrutiny. Keep the lender's loan statement each year to split the two correctly.

Documents to keep ready when you apply

Once you have settled on an EMI that fits, the lender will ask for proof that you can repay it. Typical documents include:

• PAN and Aadhaar of all applicants
• Salary slips for recent months and Form 16, for salaried applicants
• Income tax returns for the last two or three years, with computation of income
• Bank statements for the last six to twelve months
• For businesses: profit and loss account, balance sheet, GST returns, and business registration proof
• For home loans: property documents, sale agreement and approved plan

Lenders read your income tax returns closely. Returns filed on time, with income that matches your bank statements and Form 26AS, make approval smoother. Businesses with clean, up-to-date books get faster decisions; our accounting and bookkeeping service can help keep them ready.
