How to use the EMI Calculator
- Enter the loan amount and the annual interest rate quoted by your bank.
- Enter the tenure and choose whether it is in years or months.
- Press Calculate EMI to see your monthly instalment, the total interest and the total amount you will pay.
- Open the repayment schedule under the result to see how each EMI splits into principal and interest month by month.
EMI formula
- P is the loan amount (principal).
- r is the monthly interest rate = annual rate ÷ 12 ÷ 100.
- n is the number of monthly instalments.
If the interest rate is 0%, the EMI is simply P ÷ n.
Worked examples
₹5,00,000 at 10% for 60 months: r = 10 ÷ 12 ÷ 100 = 0.008333. EMI = ₹10,623.52 per month. Total payment = ₹6,37,411.34, so total interest = ₹1,37,411.34.
₹20,00,000 at 8.5% for 20 years (240 months): EMI = ₹17,356.46 per month.
How tenure changes your EMI and total interest
A longer tenure lowers the monthly EMI but increases the interest you pay overall. For a loan of ₹10,00,000 at 9% a year:
| Tenure | Monthly EMI | Total interest |
|---|---|---|
| 10 years | ₹12,667.58 | ₹5,20,109.29 |
| 15 years | ₹10,142.67 | ₹8,25,679.85 |
| 20 years | ₹8,997.26 | ₹11,59,342.29 |
Common mistakes to avoid
- Judging a loan by EMI alone. Compare the interest rate, total interest, processing fee and any insurance or prepayment charges.
- Mixing up years and months. 20 years is 240 months. Use the tenure box to choose the unit you mean.
- Entering the monthly rate as the annual rate. Always enter the yearly rate quoted by the lender. The calculator divides it by 12.
- Stretching the tenure too far. It feels affordable each month but can add a large amount of interest.
Ways to reduce the interest you pay
- Make part-prepayments when you have spare cash, since they reduce the outstanding principal.
- Choose the shortest tenure whose EMI you can comfortably afford.
- Compare offers from several lenders and ask whether a lower rate is available.
Frequently asked questions
What is an EMI?
EMI stands for Equated Monthly Instalment. It is the fixed amount you pay every month to repay a loan. Each EMI covers some interest and some principal.
Why is most of my early EMI interest?
Interest is charged on the outstanding balance, which is highest at the start. So early EMIs are mostly interest and later EMIs are mostly principal. The repayment schedule shows this clearly.
How can I reduce my EMI?
Make a larger down payment, choose a longer tenure, or look for a lower interest rate. A longer tenure lowers the EMI but increases the total interest you pay.
Does the EMI stay fixed for the whole loan?
For a fixed-rate loan, yes. For a floating-rate loan the rate can change, so either your EMI or your tenure may change. This calculator assumes a constant rate.
Do prepayments change the result?
Yes. Paying extra towards principal reduces the outstanding balance, which cuts the interest you pay and can shorten the loan. This calculator does not model prepayments, and it does not include processing fees or insurance.
What is the difference between flat rate and reducing balance interest?
This calculator uses the reducing-balance method, where interest is charged only on the amount still owed. A flat rate charges interest on the original loan amount for the whole tenure, so a flat rate is more expensive than the same number quoted as a reducing-balance rate.
Will my bank's EMI match this calculator exactly?
It should be very close for a fixed-rate loan. Small differences can come from rounding, the date of the first instalment, processing fees or insurance added by the lender.
