Fixed vs floating home loan: what would floating have to average?
A fixed-rate home loan gives you one number to plan around. A floating-rate loan starts lower and moves with the benchmark. The honest comparison is not which rate is lower today, but what the floating rate would have to average over the loan for the two to cost the same.
What would floating have to average to beat a fixed rate?
| If floating averages | Total interest (floating) | Against fixed |

Constant-rate comparison. Floating loans move at resets, so the average is over the whole loan. Fixed-rate offers from Indian lenders are often for an initial period only, after which the loan reverts to floating; check the terms.
Things to check about a fixed-rate offer
- Is it fixed for the whole tenure or only for an initial period? Many are fixed for a few years, then floating.
- What is the rate after the fixed period?
- Can you move from floating to fixed later? RBI's circular on borrower options says a switch is at the lender's option for loans since 1 October 2025; ask the lender what it offers and what it charges.
- Prepayment charges. Since 1 January 2026, lenders cannot charge pre-payment penalties on floating-rate loans to individuals for personal use. Fixed-rate loans are not covered by that bar, so ask.
