EMI Calculator

For a ₹10 lakh personal loan at 12% per annum for 5 years, your EMI would be ₹22,244 per month. Over that 5-year period, you would pay ₹3,34,640 in total interest on top of the ₹10 lakh you borrowed. This calculator shows you those numbers instantly — along with a year-by-year breakdown and the complete amortization schedule you can download.

What Is EMI?

EMI stands for Equated Monthly Installment. It is the fixed amount you pay every month to repay a loan. Each EMI payment contains two components:

• Principal component: The portion that reduces your outstanding loan balance
• Interest component: The cost of borrowing, calculated on the remaining balance

Here is the critical thing most borrowers do not realise: in the early months of a loan, most of your EMI goes to interest, not principal. On a 5-year personal loan, in month 1, roughly 50% of your EMI is interest. By month 60, less than 5% is interest. The calculator's amortization schedule shows you this shift, month by month.

EMI Formula (Worked Examples)

EMI = P × r × (1+r)ⁿ ÷ [(1+r)ⁿ − 1]

Where:

• P = Principal (loan amount)
• r = Monthly interest rate = Annual rate ÷ 12 ÷ 100
• n = Loan tenure in months

Example 1 — Personal loan: ₹5,00,000 at 11% for 3 years

• r = 11 ÷ 12 ÷ 100 = 0.009167
• n = 36
• EMI = ₹16,371/month
• Total interest = ₹89,349
• Total repayment = ₹5,89,349

Example 2 — Home loan: ₹50,00,000 at 8.5% for 20 years

• r = 8.5 ÷ 12 ÷ 100 = 0.007083
• n = 240
• EMI = ₹43,391/month
• Total interest = ₹54,13,857
• Total repayment = ₹1,04,13,857

Notice that on the 20-year home loan, you pay more in interest (₹54 lakh) than the original principal (₹50 lakh). This is normal for long-tenure loans at typical home loan rates.

How EMI Changes With Loan Tenure

Choosing a longer tenure reduces your monthly EMI but dramatically increases total interest paid. Here is how a ₹10,00,000 loan at 10% looks across different tenures:

The 5-year EMI is 75% lower per month than the 1-year option, but you pay ₹2.2 lakh more in total interest. Use this calculator to find the tenure that best balances your monthly budget against total cost.

How to Use This EMI Calculator

2. Enter the annual interest rate — use the rate quoted by your bank or lender
3. Select loan tenure — enter in years or months using the toggle
4. Add processing fee (optional) — enter as a percentage to see the total loan cost including fees
5. Select a start date (optional) — for a dated amortization schedule; defaults to today
6. Select loan type (optional) — for reference in the downloaded report
7. Click Calculate EMI — results appear with EMI, total interest, and full breakdown
8. Download report or CSV — save your full amortization schedule

Understanding the Principal vs Interest Ratio

The calculator displays a visual breakdown showing what percentage of your total repayment goes to principal versus interest. This ratio is one of the most useful numbers in loan planning:

• A personal loan for 3 years at 12%: roughly 84% principal, 16% interest
• A home loan for 20 years at 8.5%: roughly 48% principal, 52% interest
• A home loan for 30 years at 9%: roughly 40% principal, 60% interest

The longer the tenure and higher the rate, the more of your payment is going to interest rather than reducing your balance. Prepaying even one or two additional EMIs per year — especially in the first third of the loan tenure — can save a significant amount in total interest.

Year-Wise Payment Summary

In addition to month-by-month amortization, the calculator groups payments by year and shows you how much principal and interest you pay in each year of the loan, along with the remaining balance at year end. This is particularly useful for:

• Tax planning — interest on home loans is tax-deductible in many countries (consult your tax advisor)
• Prepayment planning — identifying which years offer the best return on partial prepayment
• Long-term budget forecasting across multi-year loan tenures

Does the Processing Fee Affect Your EMI?

No. The processing fee does not change your monthly EMI. It is calculated as a fixed percentage of the principal and added to the total cost of the loan — it does not factor into the EMI formula. The calculator shows both your EMI and your total loan cost including fees separately, so you can see the full picture.

What Happens at Zero Interest Rate?

If you enter an interest rate of 0%, the EMI formula does not apply. The calculator switches to a simplified calculation: EMI = Principal ÷ Total Months. This covers no-cost EMI schemes offered by some retailers, though in practice most "zero cost" EMI products include hidden charges in the product price.

Frequently Asked Questions

How is EMI calculated?

EMI = P × r × (1+r)ⁿ ÷ [(1+r)ⁿ − 1], where P = principal, r = monthly interest rate (annual rate ÷ 12 ÷ 100), n = tenure in months. For example: ₹10,00,000 at 12% for 5 years → r = 0.01, n = 60, EMI = ₹22,244.

Does the processing fee change my EMI?

No. The processing fee is calculated separately as a percentage of the principal and added to your total loan cost. It does not affect the monthly EMI amount.

Why does the amortization table only show 12 months?

The on-screen table shows the first 12 months for readability. If your loan tenure is longer than 12 months, download the full amortization schedule as a CSV using the "View Full Schedule" button — it includes every month of the loan.

What is the difference between this EMI calculator and the Loan Calculator?

This EMI calculator is designed for the standard use case: given a loan amount, rate, and tenure, find your monthly installment. The Loan Calculator on this site offers additional modes: affordability calculation (how much can I borrow given a monthly budget?) and loan term calculation (how long to repay at a given EMI?), plus bi-weekly payments and multiple compounding frequencies.

How does the tenure toggle between years and months work?

The calculator allows you to enter tenure in either years or months depending on which is more natural for your loan. Internally it converts to months for calculation. Only one input (years or months) is used at a time — the toggle switches between them.

What happens if I enter a start date?

If you provide a start date, the amortization schedule assigns calendar dates to every payment. If no start date is given, the schedule starts from today's date automatically.

How is the final EMI adjusted to reach zero balance?

Due to rounding across hundreds of monthly payments, a tiny remainder often accumulates by the final month. The calculator automatically adjusts the last payment up or down by a few rupees/cents to bring the remaining balance exactly to zero.

How is Car EMI calculated?

Car EMI (Equated Monthly Installment) is calculated using a standard formula that combines the loan amount, interest rate, and repayment period into a fixed monthly payment.

Here, P is the principal loan amount (car price minus down payment), R is the monthly interest rate (annual rate divided by 12 and converted to a decimal), and n is the total number of months in the loan tenure.

In simple terms, EMI depends on three main factors: the amount you borrow, the interest rate applied by the bank, and how long you take to repay the loan. A higher down payment reduces the loan amount and lowers EMI, a longer tenure reduces monthly installments but increases total interest, while a lower interest rate reduces EMI directly.
