Fixed vs Floating
Interest Rate Home Loan
How RBI rate changes affect your EMI, when fixed rate makes sense, EBLR explained, and how to choose the right rate type for your home loan.
Fixed vs Floating — The Core Trade-Off
Choosing between fixed and floating interest rate is one of the most consequential home loan decisions. Over a 20-year tenure, the difference can amount to Rs 5-15 lakh in total interest paid. A fixed rate offers EMI certainty; a floating rate allows participation in RBI rate cuts.
How Each Rate Type Works
| Feature | Fixed Rate | Floating Rate (EBLR-linked) |
|---|---|---|
| Rate change | Fixed for agreed period | Changes with RBI repo rate (within 3 months) |
| EMI stability | Predictable — does not change | Can rise or fall with rate changes |
| Rate level | 1-2% higher than floating | Lower to start; variable over time |
| Prepayment penalty | May apply (2-5%) | Nil (RBI-banned for individual borrowers) |
| Rate cut benefit | None — rate is fixed | Automatic benefit when rates fall |
Understanding EBLR
Since October 2019, RBI mandated all new floating rate home loans be linked to EBLR (External Benchmark Lending Rate) — for most banks, this is the RBI Repo Rate. Your home loan rate = EBLR + Bank Spread + Credit Risk Premium. When RBI changes the repo rate, banks must pass through the change within 3 months, ensuring full and fast rate transmission to borrowers.
Impact of Rate Changes on EMI
| Rate Change | New Rate (from 8.5%) | EMI Change on Rs 50L loan |
|---|---|---|
| +0.25% hike | 8.75% | +Rs 870/month more |
| +0.50% hike | 9.00% | +Rs 1,750/month more |
| -0.25% cut | 8.25% | -Rs 860/month saved |
| -0.50% cut | 8.00% | -Rs 1,720/month saved |
When Fixed Rate Makes Sense
Fixed rates are worth considering when: rates are at a cyclical low and expected to rise significantly; the loan tenure is short (under 5 years); or the borrower has a very tight budget with no tolerance for EMI increases. For long-tenure home loans (15-20 years), floating rate is almost universally better in India.
Switching Between Fixed and Floating
Conversion charge is Rs 5,000-15,000 or 0.25-0.5% of outstanding principal. Calculate whether the interest saving from switching exceeds the conversion fee. Break-even: (Annual Interest Saving) x (Remaining Years) vs Conversion Fee.
Decision Checklist
- For tenure above 10 years: floating rate is almost always the better choice in India
- Compare actual quoted rates: fixed vs current floating rate including the spread
- Confirm zero prepayment penalty on floating rate before signing
- Use the Loan Comparison Calculator to model total interest under both scenarios
- Understand how your lender adjusts: does rate change trigger EMI change or tenure change?

Frequently Asked Questions
A fixed rate home loan has an interest rate that stays constant for a period or full tenure — your EMI does not change. A floating rate home loan is linked to EBLR (External Benchmark Lending Rate, usually repo rate). When RBI changes the repo rate, floating rate and EMI change within 3 months. Most home loans in India are floating — fixed rate options are rare and carry a 1-2% premium.
For long-tenure home loans (15-20 years), floating rate is almost always better in India. Floating rates have historically averaged lower than fixed rates; RBI rate cuts pass through automatically; prepayment has zero penalty on floating (banned by RBI); and the 1-2% fixed rate premium compounds significantly over the full tenure. Fixed rates make sense only for short tenures or if rates are at a cyclical low and expected to rise sharply.
When RBI increases the repo rate, banks must increase EBLR within 3 months. This raises your floating rate home loan interest. Banks offer two options: increase EMI (same tenure) or increase tenure (same EMI). For example, a 0.5% hike on Rs 50 lakh outstanding at Rs 43,000 EMI increases EMI by approximately Rs 1,750 or extends tenure by 14 months. Rate cuts have the opposite beneficial effect.
Yes, but there is a conversion charge of Rs 5,000-15,000 or 0.25-0.5% of outstanding principal. Switch to fixed when rates are at a cyclical low to lock in; stay floating when rates are high and likely to fall. Getting this call right consistently is difficult. Most planners recommend staying on floating for long-tenure home loans given the zero-prepayment-penalty benefit.
EBLR (External Benchmark Lending Rate) is mandatorily linked to the RBI Repo Rate since October 2019. Your floating home loan rate = Repo Rate + Bank Spread + Credit Risk Premium. When RBI changes the repo rate, your EBLR and loan rate change within 3 months — ensuring full and fast transmission of monetary policy. This replaced the older MCLR system where transmission was slower and often incomplete.
If you have a fixed rate loan and rates fall, you do not benefit. Your EMI and tenure stay unchanged. You can switch to floating by paying a conversion charge, but this erodes part of the benefit. Over 20 years, rates go through multiple rise-and-fall cycles. This is why floating rate is recommended for long-tenure home loans in India — you capture the benefit of rate cuts automatically.
