An EMI (Equated Monthly Instalment) is the fixed amount you pay your lender every month until the loan is fully repaid. Each EMI has two parts: interest on the balance you still owe, and a small piece of the principal. In the early years most of your EMI goes towards interest. As the balance falls, a larger share goes towards the principal.
Check your EMI before you apply for a loan. It tells you whether the loan fits your monthly budget and lets you compare offers from different banks on equal terms.
How to use the EMI calculator
- Enter the loan amount you want to borrow.
- Enter the yearly interest rate offered by the lender.
- Choose the loan tenure in years.
- Your monthly EMI, total interest and total payment update instantly. Open the year-wise breakdown to see how much principal and interest you pay each year and what balance remains.
EMI formula
EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1)- P = loan amount (principal)
- r = monthly interest rate = yearly rate ÷ 12 ÷ 100
- n = number of monthly instalments = tenure in years × 12
Example
You take a home loan of ₹10,00,000 at 8.5% yearly interest for 20 years.
- r = 8.5 ÷ 12 ÷ 100 = 0.007083
- n = 20 × 12 = 240 months
- EMI = ₹8,678 per month
- Total payment = ₹20,82,776
- Total interest = ₹10,82,776
Over 20 years you pay more in interest than you borrowed. That is why the tenure and the rate matter so much.
How tenure changes the total cost
Same loan of ₹10 lakh at 8.5%, different tenures:
| Tenure | Monthly EMI | Total interest | Total payment |
|---|---|---|---|
| 10 years | ₹12,399 | ₹4,87,828 | ₹14,87,828 |
| 15 years | ₹9,847 | ₹7,72,531 | ₹17,72,531 |
| 20 years | ₹8,678 | ₹10,82,776 | ₹20,82,776 |
| 25 years | ₹8,052 | ₹14,15,681 | ₹24,15,681 |
| 30 years | ₹7,689 | ₹17,68,089 | ₹27,68,089 |
Stretching the loan from 20 to 30 years lowers the EMI by only ₹989 but adds almost ₹7 lakh of interest.
How a small rate difference adds up
₹10 lakh for 20 years:
| Interest rate | Monthly EMI | Total interest |
|---|---|---|
| 8.0% | ₹8,364 | ₹10,07,456 |
| 8.5% | ₹8,678 | ₹10,82,776 |
| 9.0% | ₹8,997 | ₹11,59,342 |
| 9.5% | ₹9,321 | ₹12,37,115 |
| 10.0% | ₹9,650 | ₹13,16,052 |
A 0.5% lower rate saves about ₹75,000 over 20 years on every ₹10 lakh borrowed.
Tips to reduce your loan cost
- Prepay whenever you can. Extra payments go straight to the principal, so every rupee you prepay stops charging interest. As per RBI rules, banks cannot charge a prepayment penalty on floating-rate loans taken by individuals for non-business purposes.
- Choose the shortest tenure you can comfortably afford. Use the table above to see the trade-off.
- Compare the full cost, not only the rate. Ask about processing fees, insurance bundled with the loan and other charges.
- Keep a good credit score. Lenders usually offer lower rates to borrowers with a strong repayment history.
FAQ
Does a lower EMI mean a cheaper loan?
No. A longer tenure lowers the EMI but increases the total interest you pay. Compare the total payment, not only the monthly EMI.
Does my EMI stay the same for the whole loan?
For a fixed-rate loan, yes. Most home loans in India are floating-rate loans linked to an external benchmark such as the RBI repo rate. When that rate changes, your bank changes either the EMI or the remaining tenure.
How much EMI can I afford?
Many lenders prefer your total EMIs to stay under 40–50% of your monthly take-home income. Keeping it lower leaves room for savings and emergencies.
Does this calculator include processing fees or insurance?
No. It calculates only principal and interest. Add any fees or insurance premiums separately to see the full cost.
Can I use it for car, personal and education loans?
Yes. The EMI formula is the same for all reducing-balance loans. Just enter the loan amount, rate and tenure offered to you. For a tenure in months, enter half years, for example 1.5 years for 18 months.
