Fixed vs Floating Interest Rate â Which is Better?
Fixed rates offer payment certainty â your EMI never changes regardless of RBI policy shifts or market conditions. Floating rates (also called variable rates) move with the repo rate â they start lower but can rise over time. Floating rate loans are currently popular in India for home loans (linked to EBLR â External Benchmark Lending Rate), but carry the risk of rate hikes adding significantly to total interest paid over a 20-year period.
EMI Formula for Both
r = monthly rate, n = months. For floating, r changes as RBI revises rates.
Break-Even: When Does Floating Become More Expensive?
If the floating rate rises above the fixed rate for sustained periods, the cumulative extra interest eventually exceeds the initial savings. This calculator simulates 3 scenarios to show your risk envelope.
Fixed vs Floating: Historical Context (India)
| Period | RBI Repo Rate | Home Loan Rate | Impact on Floating |
|---|---|---|---|
| 2020-2022 (Low Rate) | 4.00% | 6.5â7% | Floating much cheaper |
| 2022-2023 (Rate Hike) | 6.50% | 8.5â9.5% | Floating EMI rose by âš5,000â15,000 |
| 2024-2025 | 6.25% | 8.25â9% | Modest relief after minor cuts |
| 2026 (Projected) | 5.75â6% | 7.75â8.5% | Rate cuts expected |
Frequently Asked Questions
When RBI is in rate-cutting cycle (as in 2024-26), floating rates are better â you benefit from reductions without refinancing. When RBI is hiking rates, fixed provides safety. Most financial advisors recommend floating if: your loan tenure exceeds 10 years and current floating rate is below fixed by 0.75%+.
EBLR is the RBI-mandated system (since Oct 2019) where home loan floating rates must be linked to an external benchmark â typically the RBI Repo Rate. Banks add a spread (margin) over the repo rate. When RBI cuts repo by 0.25%, your EMI reduces proportionally within 3 months.
Yes, most banks allow conversion, but charge a conversion fee (typically 0.5â2% of outstanding loan amount). The switch makes sense when rates are rising sharply and you want EMI certainty. Calculate whether the conversion fee is worth the rate savings over your remaining tenure.
Approximately: For a âš50 Lakh loan at 8.5% for 20 years, a 2% rate hike increases monthly EMI by roughly âš6,000â7,000. Over the remaining tenure, this could add âš10â15 Lakhs in additional interest. This calculator shows your exact exposure.
Yes â some banks offer teaser loans: fixed rate for the first 2â5 years, then convert to floating. This provides initial EMI stability during the high-expense early years of homeownership. Check the spread and conversion terms carefully before choosing this option.
When the cumulative interest paid on a floating loan (averaging your rate over the full tenure) exceeds what a fixed rate loan would have cost. The key variable is the future average floating rate. If it rises and stays 1â2% above the fixed rate for 5+ years, fixed becomes cheaper in hindsight.
