An EMI (Equated Monthly Instalment) is the fixed amount you pay your bank or NBFC every month until a loan is fully repaid. Each EMI covers part of the interest due for that month and part of the principal. This calculator gives you the EMI, the total interest over the loan’s life, the total amount you will pay back, and a month-by-month amortization schedule. It works for any fixed-rate loan: home, car, two-wheeler, personal, education or consumer durable loans.
How to use the EMI calculator
- Loan amount: the principal you are borrowing, not the price of the property or car. For a ₹40 lakh flat with a ₹10 lakh down payment, enter ₹30 lakh.
- Interest rate (% per annum): the annual rate in your sanction letter. Banks quote home loans as an annual floating rate linked to the repo rate (EBLR). Use today’s rate.
- Tenure: the repayment period in years. Home loans usually run 15–30 years, car loans 3–7 years and personal loans 1–5 years.
- Press Calculate EMI to see the monthly EMI, the principal-to-interest split and the full repayment schedule.
EMI formula
Indian banks calculate EMIs on a reducing-balance basis with this standard formula:
P = principal (loan amount)
r = monthly interest rate = annual rate ÷ 12 ÷ 100
n = number of monthly instalments = years × 12
Because interest is charged only on the outstanding balance, the interest part of each EMI shrinks month by month and the principal part grows, even though the EMI itself stays the same.
Worked example: ₹30 lakh home loan at 8.5% for 20 years
- P = 30,00,000; r = 8.5 ÷ 12 ÷ 100 = 0.0070833; n = 240
- EMI = ₹26,035 per month
- Total paid = 26,035 × 240 ≈ ₹62.48 lakh
- Total interest ≈ ₹32.48 lakh, more than the amount borrowed
In month 1, interest is 30,00,000 × 0.0070833 = ₹21,250, so only ₹4,785 of that first EMI reduces the principal. That is why prepaying early in a loan saves so much interest.
How tenure changes your EMI and total interest
A longer tenure lowers the EMI but raises the total interest sharply. Here is the same ₹30 lakh loan at 8.5%:
| Tenure | Monthly EMI | Total interest | Total repayment |
|---|---|---|---|
| 15 years | ₹29,542 | ₹23.18 lakh | ₹53.18 lakh |
| 20 years | ₹26,035 | ₹32.48 lakh | ₹62.48 lakh |
| 25 years | ₹24,157 | ₹42.47 lakh | ₹72.47 lakh |
Going from 20 to 25 years cuts the EMI by under ₹1,900 a month but adds about ₹10 lakh of interest. If you can afford a slightly higher EMI, a shorter tenure is almost always cheaper.
Typical EMIs for common loans
| Loan | Amount | Rate (illustrative) | Tenure | EMI | Total interest |
|---|---|---|---|---|---|
| Car loan | ₹8,00,000 | 9.0% | 5 years | ₹16,607 | ₹1,96,401 |
| Personal loan | ₹5,00,000 | 11.0% | 3 years | ₹16,369 | ₹89,297 |
| Personal loan | ₹5,00,000 | 11.0% | 5 years | ₹10,871 | ₹1,52,273 |
| Consumer loan | ₹2,00,000 | 13.0% | 2 years | ₹9,508 | ₹28,201 |
Rates are illustrative only. Your actual rate depends on your lender, credit score, income and the loan product.
How to reduce your EMI or total interest
- Make a bigger down payment. Every rupee you don’t borrow saves interest for the full tenure.
- Improve your CIBIL score. A score above 750 usually gets you the lender’s best rate, and a 0.5% lower rate on a ₹30 lakh, 20-year loan saves roughly ₹2 lakh.
- Prepay when you can. RBI rules do not allow foreclosure or part-prepayment charges on floating-rate loans to individuals. A yearly prepayment from your bonus can cut years off a home loan.
- Ask for a rate reset or balance transfer. When the repo rate falls, existing borrowers on older benchmarks may not get the full cut. Ask your bank to move you to the current EBLR, or compare offers from other lenders.
- Keep EMIs under about 40–50% of take-home pay. Most lenders cap your FOIR (fixed obligations to income ratio) in this range. Staying below it leaves room for emergencies.
Flat rate vs reducing balance
Some dealers and small lenders quote a “flat” rate. With a flat rate, interest is charged on the original principal for the whole tenure, even as you repay it. A 10% flat rate over 3 years costs about the same as roughly 17–18% on a reducing balance. This calculator uses the reducing-balance method that banks use. If someone quotes you a flat rate, ask for the equivalent reducing rate or the APR so you can compare offers fairly.
What the EMI does not include
The EMI covers principal and interest only. Budget separately for the processing fee (often 0.25%–2% of the loan), loan insurance if you take it, property registration and stamp duty for a home, and pre-EMI interest if you buy an under-construction flat and the loan is disbursed in stages.
Frequently asked questions
How is EMI calculated?
EMI = P × r × (1 + r)^n ÷ [(1 + r)^n − 1], where P is the loan amount, r is the monthly rate (annual rate ÷ 1200) and n is the number of months. For ₹30 lakh at 8.5% for 20 years, the EMI is ₹26,035.
Does a longer tenure reduce EMI?
Yes, but the total interest goes up a lot. A ₹30 lakh loan at 8.5% has an EMI of ₹29,542 over 15 years and ₹24,157 over 25 years, yet the 25-year loan costs about ₹19 lakh more in interest.
Is it better to prepay a home loan or reduce EMI?
When you prepay, banks usually let you either reduce the tenure or reduce the EMI. Reducing the tenure saves more interest. Reducing the EMI eases your monthly cash flow. Prepayments made early in the loan give the biggest savings.
Are there prepayment charges on home loans in India?
RBI rules do not allow banks and NBFCs to charge foreclosure or prepayment penalties on floating-rate loans taken by individuals for non-business purposes. Fixed-rate loans can carry charges, so check your loan agreement.
Why is most of my early EMI going towards interest?
Interest is charged on the outstanding balance, which is highest at the start. In the first month of a ₹30 lakh, 8.5% loan, ₹21,250 of the ₹26,035 EMI is interest. The principal part grows every month after that.
Is this EMI calculator accurate for car and personal loans too?
Yes. It uses the standard reducing-balance formula that banks use for home, car, two-wheeler, personal and education loans. Small differences can come from how a lender treats the first broken-period interest.
