EMI Calculator

How to Use the EMI Calculator

The calculator is designed to be used in a few seconds, whether you prefer typing exact numbers or dragging the sliders to explore different scenarios.

1. Enter the loan amount. Type the principal you plan to borrow into the "Loan Amount" field, or drag the slider below it. The slider is useful for quickly scanning a range; the number field is better once you know the exact figure.
2. Enter the annual interest rate. Use the rate quoted by your bank or lender (per annum). If you only have a monthly rate, multiply it by 12 before entering it here.
3. Enter the loan tenure in years. This is the total repayment period. Longer tenures reduce the EMI but increase the interest you eventually pay.
4. Review your monthly EMI. The result updates instantly as you change any input, so you can compare scenarios without refreshing the page.
5. Check the total interest and total payment. These figures show what the loan will actually cost over its full life, not just the monthly outgo.
6. Expand the amortization schedule. Click "Expand Amortization Schedule" to see a month-by-month breakdown, and use "Download PDF" to save or share it.

What Does the EMI Calculator Calculate?

Based on the loan amount, interest rate and tenure you enter, the calculator produces four outputs:

• Monthly EMI — the fixed amount you would pay every month for the entire tenure.
• Total Interest Payable — the sum of the interest portion across every EMI, i.e. the true cost of borrowing.
• Total Payment — the loan amount plus total interest, or in other words, everything you would hand back to the lender by the end of the tenure.
• Amortization Schedule — a month-wise table showing the opening balance, EMI, interest, principal and closing balance for every instalment.

What is EMI?

EMI stands for Equated Monthly Installment — a fixed amount that a borrower pays to a lender on a set date every month until the loan is fully repaid. Each EMI is made up of two parts: interest on the outstanding balance, and a portion of the principal. Even though the EMI amount itself stays the same every month, the split between interest and principal changes over the life of the loan, which is exactly what the amortization schedule below the calculator shows.

EMI Calculation Formula

This calculator uses the standard reducing-balance EMI formula used by Indian banks and NBFCs:

• P = Principal loan amount
• r = Monthly interest rate (the annual rate you enter, divided by 12 and by 100)
• n = Total number of monthly instalments (tenure in years × 12)

Because lenders quote interest rates per annum but charge interest monthly, the annual rate is first converted into a monthly rate before it is used in the formula. This calculator performs that conversion automatically — you only need to enter the annual rate.

EMI Calculation Example

Here is a worked example using the calculator's default values:

You can verify this yourself: set the calculator above to a ₹10,00,000 loan amount, a 9% interest rate and a 5-year tenure, and it will produce the same figures.

How Loan Amount Affects EMI

The EMI is directly proportional to the principal: for the same interest rate and tenure, borrowing twice as much roughly doubles the EMI. A larger loan amount also increases the absolute total interest paid, even though the interest rate itself hasn't changed, simply because interest accrues on a bigger outstanding balance every month. This is why it's worth borrowing only what you genuinely need rather than the maximum amount a lender is willing to offer.

How Interest Rate Affects EMI

A higher interest rate increases the EMI, the total interest payable and the total repayment amount, all else being equal. For long-tenure, high-value loans such as home loans, even a difference of half a percentage point in the interest rate can translate into a meaningful amount over the full tenure, because interest compounds on the outstanding balance every month for many years. It's worth comparing the interest rate offered by more than one lender before committing to a loan, since rates vary by lender, loan type, borrower profile and prevailing market conditions.

How Loan Tenure Affects EMI

Tenure has an inverse relationship with EMI but a direct relationship with total interest:

• Shorter tenure: higher monthly EMI, but lower total interest paid over the life of the loan.
• Longer tenure: lower monthly EMI, which can make a loan look more affordable month to month, but higher total interest paid overall.

For example, stretching a ₹10,00,000 loan at 9% from 5 years to 10 years will noticeably lower the EMI, but roughly double the total interest paid — try it in the calculator above to see the exact numbers for your own loan amount and rate.

What is a Reducing-Balance EMI?

This calculator uses the reducing-balance (also called diminishing-balance) method, which is the standard method used by banks and NBFCs in India for home loans, car loans and most personal loans. Under this method, interest is calculated each month on the outstanding principal balance, not on the original loan amount. As you repay principal every month, the outstanding balance shrinks, so the interest component of each subsequent EMI is smaller and the principal component is larger — even though the EMI itself stays constant. This is different from a flat-rate loan, where interest is calculated on the full original amount for the entire tenure, which typically results in a higher effective interest cost for the same quoted rate. Always check which method a lender is using, since terms can vary between products and lenders.

Understanding the Amortization Schedule

Each row of the amortization schedule generated above represents one month of the loan and shows:

• Month — the instalment number, from 1 to the total tenure in months.
• Opening Balance — the outstanding principal at the start of that month.
• EMI — the fixed instalment paid that month.
• Interest — the portion of that EMI charged as interest on the opening balance.
• Principal — the portion of that EMI that goes toward reducing the loan balance.
• Closing Balance — the outstanding principal after that month's payment, which becomes next month's opening balance.

Reviewing the full schedule is useful before making a prepayment, applying for a balance transfer, or simply understanding how much of your loan you'll have paid off by a certain year. Note that amounts shown are rounded to the nearest rupee for readability.

Home Loan EMI Calculator

Home loans typically run for 10 to 30 years and are the largest, longest-tenure loans most borrowers take. Use this calculator to enter the property loan amount, the rate quoted by your bank or housing finance company, and your preferred tenure to see the resulting EMI and total interest. Because home loans run for so long, even small differences in interest rate or tenure can change the total interest by a large amount — it's worth running a few scenarios before deciding on a tenure. Home loan interest rates vary by lender, loan amount, borrower profile and current market conditions, so treat any rate you enter here as an estimate to check against your actual sanction letter.

Car Loan EMI Calculator

Car loans are usually shorter, typically ranging from 1 to 7 years. Enter the on-road price you plan to finance (after any down payment), the interest rate quoted by your bank or the dealership's financing partner, and your chosen tenure, to see your monthly EMI. Since car loans have shorter tenures than home loans, the tenure you choose has a large effect on affordability — a shorter tenure keeps total interest low but raises the EMI, which is worth weighing against your monthly budget.

Personal Loan EMI Calculator

Personal loans are unsecured, generally have shorter tenures (1 to 5 years) and carry higher interest rates than secured loans like home or car loans, since the lender takes on more risk without collateral. Use the calculator to check the EMI and total interest for the amount and tenure you're considering before applying, since a high-rate, short-tenure personal loan can carry a substantial EMI relative to the loan amount.

Education Loan EMI Calculator

Education loans often include a moratorium period — typically the course duration plus a few months — during which repayment may be deferred or reduced, with interest still accruing in the background depending on the lender's terms. This calculator computes a standard EMI schedule starting from month one, so if your loan has a moratorium period, use it to estimate the EMI for the actual repayment phase once that period ends, and check with your lender on how any accrued interest during the moratorium affects the final principal.

EMI vs Total Interest

It's tempting to judge a loan offer purely by how affordable the monthly EMI looks, but that can be misleading. A lower EMI is often the result of a longer tenure, not a better deal — and a longer tenure usually means a higher total interest bill over the life of the loan. Before choosing a loan amount, rate or tenure, look at both the EMI and the total interest/total payment figures together, and consider what you can comfortably afford each month versus what the loan will cost you in total.

Tips Before Taking a Loan

• Compare interest rates and the effective cost across more than one lender, not just the headline rate.
• Check processing fees, documentation charges and any other one-time costs — these add to the real cost of the loan.
• Compare a few tenure options side by side using this calculator, rather than accepting the first tenure suggested to you.
• Look at the total repayment amount, not only the EMI, when comparing offers.
• Review prepayment and foreclosure terms, including any penalty, before signing.
• Read the full loan agreement, including fine print on fees, penalties and rate-reset clauses for floating-rate loans.
• Avoid choosing a loan amount just because the resulting EMI looks affordable — check that the total cost fits your longer-term plans too.
• Keep an emergency buffer separate from your EMI budget, so a temporary income disruption doesn't put your repayments at risk.

Common EMI Calculation Mistakes

• Confusing annual and monthly interest rates. Always enter the annual rate quoted by the lender; entering a monthly rate by mistake will produce a wildly incorrect EMI.
• Ignoring tenure when comparing loans. Two loans with the same EMI can have very different total interest costs if their tenures differ.
• Looking only at the EMI. As explained above, a lower EMI doesn't always mean a cheaper loan once total interest is considered.
• Ignoring processing fees and other charges. These aren't part of the EMI formula but do add to your real cost of borrowing.
• Ignoring prepayment conditions. Some loans charge a penalty for early repayment, which can offset the interest you'd save.
• Assuming an advertised rate applies to everyone. Lenders price loans based on credit profile, loan amount, tenure and other factors, so your actual rate may differ from an advertised "starting from" rate.
• Confusing flat-rate and reducing-balance calculations. A flat interest rate applied to the original loan amount for the full tenure is not the same as a reducing-balance rate, even if the quoted percentage looks similar — the effective cost of a flat-rate loan is usually higher.
