The difference
- Floating rate. It moves with a benchmark chosen by the lender, such as the RBI repo rate for many newer bank home loans. When your rate is reset, your EMI, your tenure or both can change.
- Fixed rate. It stays the same for a set period, which could be the entire loan or only the first few years. Read the terms carefully. A loan described as fixed may later become floating, and some agreements allow the lender to revise the rate.
In India, most home loans are floating. Personal loans and car loans are more commonly fixed, though this varies by lender.
What a rate change does
Long loans are very sensitive to the rate. Here is a ₹40 lakh loan over 20 years, assuming each rate lasts for the full term.
| Rate | EMI | Total interest |
|---|---|---|
| 7% | ₹31,012 | ₹34.43 lakh |
| 8% | ₹33,458 | ₹40.30 lakh |
| 9% | ₹35,989 | ₹46.37 lakh |
| 10% | ₹38,601 | ₹52.64 lakh |
Going from 8% to 9% adds ₹2,531 to the EMI and about ₹6 lakh in interest. These figures are illustrations rather than forecasts, since nobody knows how rates will move over 20 years.
Watch out for a longer tenure
When rates rise, many lenders first keep your EMI the same and extend the tenure. The monthly payment feels unchanged, but the cost can jump.
Suppose that ₹40 lakh loan began at 8% with a ₹33,458 EMI, and the rate became 9% right at the start. If the EMI stayed the same, the loan would take about 25 years and 4 months to repay instead of 20 years, and total interest would be about ₹61.63 lakh. Raising the EMI to ₹35,989 instead would keep it to 20 years and about ₹46.37 lakh.
So when your rate is reset, check your remaining tenure as well as your EMI. RBI instructions on EMI-based personal loans ask lenders to communicate resets clearly and offer options such as a higher EMI, a longer tenure, or a switch to a fixed rate, subject to any applicable charges. Ask your lender which options apply to your loan.
Prepayment charges
RBI directions bar lenders from charging prepayment fees on floating-rate loans taken by individuals for non-business purposes. They apply to loans sanctioned or renewed from 1 January 2026, and earlier loans follow the rules that applied at the time. Fixed-rate loans can carry prepayment charges, and the sanction letter and Key Facts Statement should state them.
If you expect to make lump-sum payments, for example from bonuses, this can matter as much as the rate. See how prepayment reduces your interest.
How to compare the two
| Floating | Fixed | |
|---|---|---|
| EMI certainty | Can change at reset | Steady during the fixed period |
| If rates fall | You can benefit | You stay at your rate unless you switch |
| If rates rise | EMI or tenure can go up | You are protected during the fixed period |
| Starting rate | Often lower | Often higher |
| Prepayment | No charge on qualifying loans | Charges may apply |
How to choose
There's no universally better option, because it depends on your budget and your loan.
- A floating rate can suit you if you have a long loan, room in your budget for a higher EMI, and plans to prepay.
- A fixed rate can suit you if your budget is tight, the loan is short, and knowing your payment is worth paying more.
- Test before you sign. Put a rate 1 to 2 points higher into the optional interest rate field of the home loan calculator. If that EMI would strain your budget, consider a smaller loan.
Questions to ask your lender
- Which benchmark is my rate linked to, and how often does it reset?
- What is the spread over the benchmark, and can it change?
- When rates rise, does my EMI or my tenure change first, and can I choose?
- If the rate is fixed, for how long, and what happens afterwards?
- What does it cost to switch between rates or to prepay?
