Fixed vs Floating Interest Rates — Which Should You Choose for Your Home Loan?

When you take a home loan, the bank asks you to choose: fixed rate or floating rate. Most people pick floating because the agent says it’s lower. That’s often the right call — but not always.

Here’s what each actually means, and how to think about the choice.

Fixed rate: predictability at a premium

A fixed rate loan locks in your interest rate for the entire tenure — your EMI is the same in month 1 and month 240. You know exactly what you’re paying.

The cost of that predictability: fixed rates are typically 1–2.5% higher than floating rates at the time of the loan.

When fixed makes sense:

• You’re taking the loan at historically low rates and expect rates to rise
• Your income is variable (freelancer, commission-based) and budget certainty matters more than optimization
• You’re in a short tenure (under 7 years) where rate fluctuation has less impact

Floating rate: lower cost, higher uncertainty

A floating rate loan is tied to a benchmark — in India, typically the RBI repo rate, transmitted through your bank’s RLLR (Repo Linked Lending Rate) or MCLR. When the benchmark moves, your rate moves.

The advantage: floating rates are almost always lower than fixed rates to start with, and over a 20-year period, rate cycles tend to average out.

The risk: if rates spike (like they did globally in 2022–23), your EMI increases or your tenure extends.

The math over 20 years

Let’s say you borrow ₹50 lakh for 20 years.

But if floating rates rise by 1.5% and stay there for 5 years, the savings narrow or flip.

Use our EMI Calculator to run these scenarios — plug in different rates and tenures to see how sensitive your total payment is to rate changes.

The honest answer

For most borrowers in India taking a 15–20 year loan: go floating. Here’s why:

1. The initial rate gap (1–2%) compounds into significant savings over time
2. RBI rate cycles historically revert — periods of high rates are followed by cuts
3. You can always make prepayments when rates are high to reduce your burden

Choose fixed only if you’re near the bottom of a rate cycle and have strong reason to believe rates will rise significantly — or if the predictability has real personal value (e.g. you’re on a tight budget with no buffer).

When in doubt: run both scenarios in the EMI Calculator and look at the total interest paid, not just the monthly EMI.
