Loan EMI Calculator

The tool opens with sample figures (10,000 at 7.5% over 5 years) so you can see the layout, and every result refreshes as soon as you change a field.

1. Enter the Loan amount, the sum you are borrowing before any interest is added.
2. Type the Annual interest rate (%), for example 8.5. A rate of 0 is accepted and gives a plain division of the loan over the months.
3. Enter the Loan term as a whole number, then use Term in to choose Years or Months. A term of 5 years and a term of 60 months give identical results.
4. Change the Currency symbol if you do not want a dollar sign. It only changes the symbol shown; nothing is converted.
5. Read the large Monthly payment (EMI) figure, then the rows beneath it: Loan amount, Total interest, Total paid, Interest as share of payments and Payoff date. A bar compares principal with interest, and a table lists Principal paid, Interest paid and Balance for each year of the loan.

Payoff date is simply today plus the number of monthly payments, so treat it as a guide rather than a contract date.

An equated monthly instalment is the one fixed payment that clears both the borrowed amount and the interest over a set number of months. The calculator uses the reducing-balance formula EMI = P × r × (1 + r)^n / ((1 + r)^n - 1). Here P is the loan amount, r is the annual rate divided by 12 and by 100, and n is the number of months.

Take 10,000 at 12% a year over 24 months. The monthly rate r is 0.01 and n is 24, so (1.01)^24 is about 1.2697 and the EMI comes to 470.73. Over 24 payments you repay about 11,297.63, which means total interest of 1,297.63.

The first payment shows how the split works: interest is 10,000 × 0.01 = 100.00, so only 370.73 reduces the balance. Each later month the interest falls a little and the principal share grows. The yearly table for this loan reads as follows.

With a rate of zero the formula is not needed and the payment is the loan divided by the months (416.67 for 10,000 over 24 months). The term is rounded to whole months, and the payment is not rounded to cents, so a lender whose schedule rounds every instalment may differ by a few cents on the final payment.

Stretching a loan lowers the instalment but raises the cost, because interest is charged on the outstanding balance for more months. The same 25,000 at 7.5% shows the trade-off.

Doubling the term cuts the instalment by about 40% but more than doubles the interest. The Interest as share of payments row puts the same point as a percentage of everything you repay: 16.8% for the five-year loan and 29.8% for the ten-year one. Compare that row and Total interest, not only the EMI, when you choose between offers.

The tool has no field for extra repayments. If you plan to overpay or settle early, run it again with the balance still owed and the months remaining to see the payment that would apply from that point. Checking a lender's quoted instalment against the figure here is also a quick way to spot a quote that includes fees or a different rate.

The calculator assumes a fixed rate, payments on time and no extras. It leaves out processing fees, insurance, prepayment charges and any change of rate on a floating-rate loan. It also assumes interest on the reducing balance. A flat-rate quote, where interest is charged on the original amount for the whole term, looks cheaper than it is, and its payment will not match this tool; the simple interest calculator shows how flat interest behaves.

For a home purchase with property tax, insurance and association fees, use the mortgage calculator. For a revolving card balance, the credit card payoff calculator fits better, and the percentage calculator helps you compare rates. Results are an estimate for general information and are not financial advice or a lender quote.
