What you can do here

Instant, exact EMI

Change the amount, rate or tenure with a slider or by typing, and the EMI and totals update immediately — to the rupee.

Yearly breakdown chart

See how each year’s payments split between principal and interest. Early years are mostly interest; the chart shows exactly how that shifts.

Full repayment schedule

Switch between a yearly and a monthly table showing principal, interest and the balance left, then download it as CSV for Excel or Google Sheets.

Prepayment planner

Add an extra amount every month to see the interest you save and how many years sooner the loan is closed.

Indian number format

Amounts appear as ₹50,00,000 with “50 lakh” written out, and the chart axis uses L and Cr, so large numbers are easy to read.

Works for any loan

Home loans, car loans, personal loans, education loans and mortgages all use the same formula — just enter your figures.

The sequence

How to calculate your EMI

  1. 1

    Enter the loan amount

    Type the amount you will borrow or drag the slider. Pick your currency if it isn’t rupees.

  2. 2

    Enter the interest rate

    Use the annual rate from your lender’s offer, for example 8.5%.

  3. 3

    Set the tenure

    Choose the repayment period in years or months. Longer tenures lower the EMI but raise the total interest.

  4. 4

    Read the results

    Your EMI, total interest and total payable appear straight away. Add an extra monthly payment to see how prepaying helps, and download the schedule if you need it.

Worth knowing

  • EMI Calculator on Toolspire: uses the standard reducing-balance formula EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where r is the monthly interest rate and n the number of months.
  • Shows the monthly EMI, total interest, total amount payable and the principal-to-interest split.
  • Builds a full month-by-month and year-by-year repayment schedule, downloadable as a CSV file.
  • Models an extra monthly prepayment and reports the interest saved and how much sooner the loan closes.
  • Supports rupees (with lakh/crore formatting), US dollars, euros, pounds and UAE dirhams.
  • Example: ₹50 lakh at 8.5% for 20 years gives an EMI of ₹43,391 and total interest of ₹54,13,879.

What is an EMI?

An EMI (equated monthly instalment) is the fixed amount you pay your lender every month until a loan is repaid. Each EMI covers that month’s interest on the outstanding balance, and the rest reduces the principal. Because the balance falls over time, the interest part of each EMI shrinks and the principal part grows — even though the EMI itself stays the same.

The EMI formula

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

Here P is the loan amount, r is the monthly interest rate (the annual rate ÷ 12 ÷ 100), and n is the number of monthly payments. For ₹10,00,000 at 10% a year for 20 years: r = 10 ÷ 12 ÷ 100 = 0.008333 and n = 240, which gives an EMI of ₹9,650. Over 20 years you would repay ₹23,16,052, of which ₹13,16,052 is interest.

How prepayment saves money

Any amount you pay on top of the EMI goes straight to the principal, so every later month charges interest on a smaller balance. Take a ₹50 lakh home loan at 8.5% for 20 years: the EMI is ₹43,391 and the total interest ₹54,13,879. Paying just ₹5,000 extra every month closes the loan in 15 years 7 months instead of 20 and saves about ₹13.9 lakh in interest.

Prepayments save the most early in the loan, when the balance — and so the interest — is highest. Many lenders also let you keep the tenure and reduce the EMI instead; this calculator shows the “shorter tenure” option, which saves more interest.

How to lower your EMI or total interest

  • Make a bigger down payment. Every rupee you don’t borrow saves interest for the whole tenure.
  • Compare interest rates. On a ₹50 lakh, 20-year loan, 0.5% lower rate cuts the EMI by roughly ₹1,600 a month.
  • Choose the shortest tenure you can afford. A longer tenure lowers the EMI but multiplies the total interest.
  • Prepay whenever you can, especially in the first years. Check your loan agreement for any prepayment charges first.
  • Keep your EMIs affordable. A common rule of thumb is to keep all EMIs together below 40–50% of your monthly take-home income.

FAQ

Questions about EMI Calculator

Where does EMI Calculator run?

EMI Calculator runs in this tab on Toolspire. What you type or drop in is not sent to us and is not stored on a server.

How is EMI calculated?

With the reducing-balance formula EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where P is the loan amount, r the monthly rate (annual rate ÷ 12 ÷ 100) and n the number of months. This calculator applies it exactly and builds the full schedule from it.

Why is my bank’s EMI slightly different?

Lenders may round differently, count interest from the disbursal date, or add processing fees and insurance to the loan. The formula is the same, so the difference is normally small.

Does a longer tenure save money?

No. A longer tenure lowers the EMI but increases the total interest. A ₹10 lakh loan at 10% costs ₹2,74,823 in interest over 5 years but ₹13,16,052 over 20 years.

Is it better to reduce the EMI or the tenure after a prepayment?

Reducing the tenure saves more interest; reducing the EMI eases your monthly budget. If you can comfortably keep paying the same EMI, choose the shorter tenure.

Can I calculate EMI for a car, personal or education loan?

Yes. All of these are standard reducing-balance loans. Enter the amount, rate and tenure from your offer — or tap one of the examples to start.

Does this work for a flat-rate loan?

No. Some personal and vehicle loans quote a “flat” rate charged on the original amount for the whole tenure, which costs much more than the same reducing rate. Ask the lender for the reducing-balance rate (or APR) and enter that.

Can I download the repayment schedule?

Yes. Click CSV above the schedule to download every month’s payment, principal, interest, extra payment and balance for Excel or Google Sheets.

Is my data saved?

No. The calculations run in this tab, and nothing you enter is stored or sent anywhere.
