Most home loans today are on floating rates, which means the interest rate can change during the loan. When it does, the bank either changes your EMI or changes the number of months you will pay.
A worked example
Take a ₹30 lakh loan over 20 years (240 months). The monthly EMI at three interest rates is:
| Interest rate | Monthly EMI | Total interest over 20 years |
|---|---|---|
| 8.50% | ₹26,035 | about ₹32.5 lakh |
| 8.75% | ₹26,511 | about ₹33.6 lakh |
| 9.00% | ₹26,992 | about ₹34.8 lakh |
A half-point rise adds about ₹957 to the EMI and roughly ₹2.3 lakh to the total interest.
EMI or tenure?
If the bank keeps your EMI unchanged at ₹26,035 after the rate rises to 9%, the loan would run for about 267 months instead of 240 — more than two extra years.
Frequently asked questions
Which is better, a higher EMI or a longer tenure?
If you can afford it, a higher EMI usually costs less in total interest. A longer tenure keeps the monthly budget the same but adds interest.
Can I choose?
Many lenders let borrowers choose, especially on request. Ask your bank in writing and keep the reply.
Do prepayments help?
Yes. Even small prepayments early in the loan reduce the principal and the total interest. Check whether your loan has any prepayment charges.
The figures above use the standard EMI formula and ignore fees and insurance. Your bank's statement is the final word for your own loan.
