Fixed vs floating interest rate: how to choose

Last updated 12 Nov 2026

A fixed interest rate stays the same for the period your agreement names. A floating rate moves when the benchmark it is linked to moves, so your EMI or your tenure changes with it. Fixed gives you a predictable payment; floating gives you a payment that follows the market in both directions. Most home loans for individuals in India are floating, while many personal, car and gold loans are fixed.

The choice matters more the longer the loan runs. On a one-year loan the gap between two offers is small; on a twenty-year home loan the wrong terms can cost lakhs. This guide explains how each type works, what a reset really does to you, and a simple way to decide. For current rate levels, see the interest rates page, because guides do not quote rates.

How a fixed rate works

With a fixed interest rate the lender sets the rate when it sanctions the loan, and it stays unchanged for the fixed period in your agreement. Your EMI, calculated on a reducing balance, does not move while the rate is fixed. You can plan a household budget around it.

Read the word "period" carefully. Some long loans are fixed only for the first few years and then become floating. Lenders sometimes call these offers semi-fixed or hybrid. The agreement and the Key Fact Statement must tell you what the rate will be linked to once the fixed period ends. If they do not, ask before you sign.

A fixed rate usually starts higher than a floating rate on a long loan, because the lender is taking on the risk that market rates rise. In return you are protected from that rise.

How a floating rate works

A floating interest rate is linked to an external benchmark such as the repo rate (the EBLR route) or, on older loans, the lender's internal MCLR. The lender adds a spread, and the spread is set in your agreement. When the benchmark changes and your loan resets, your rate changes with it. Our guide on repo rate, EBLR and MCLR explains the links in detail.

When the rate falls, you gain. When it rises, you pay more. Neither direction is in your control, and no one can promise which way it will go.

What a reset does to your loan

When a floating rate changes, a lender can do one of two things. It can change your EMI and keep your tenure, or keep your EMI and change your tenure. Many borrowers do not notice the second route. If rates rise and your EMI stays the same, your loan quietly gets longer, sometimes by years. Ask the lender which method it uses, how often the rate resets, and whether it will tell you in writing every time.

Worked example: a borrower has a ₹40,00,000 home loan over 20 years. A rate rise at a reset can be absorbed in two ways. In the first, the EMI goes up and the loan still ends on the original date. In the second, the EMI is unchanged and the end date moves out by several months or more. Both cost you more in total interest. The second is easier on the monthly budget and harder on the lifetime cost. Put your own numbers into the EMI calculator at two different rates to see the gap.

The main differences at a glance
Point	Fixed rate	Floating rate
Rate during the period	Stays unchanged for the fixed period	Moves when the benchmark moves and the loan resets
EMI	Predictable	Can rise or fall, or the tenure can change instead
Starting level	Often higher on long loans	Often lower at the start on long loans
Who bears the risk of rising rates	You are protected for the fixed period	You bear it
Who gains if rates fall	You do not, unless you switch	You do, at the next reset
Common on	Personal, car, gold and many short loans	Home loans and loans against property for individuals
Early repayment	The lender's policy applies; ask for the charge in writing	No prepayment charge for non-business loans to individuals sanctioned or renewed from 1 January 2026

Prepayment charges: what the RBI says

The Reserve Bank of India's Pre-payment Charges on Loans Directions, 2025 say that a regulated lender may not levy a pre-payment charge on a floating-rate loan given to an individual for a purpose other than business. This applies regardless of the source of the money you use to prepay and without a minimum lock-in period. The Directions apply to loans sanctioned or renewed on or after 1 January 2026. For other loans, any charge follows the lender's approved policy and must be stated in your agreement. Loans sanctioned earlier may follow older rules, so check your own papers.

This matters for your decision. On a floating-rate non-business loan you can usually repay early or move to another lender without a prepayment charge, which makes a floating rate easier to leave if it turns against you. See loan prepayment and foreclosure for how to do it.

How to decide

Choose fixed if your budget is tight, your income is steady and a rise in your EMI would hurt. The certainty is worth a higher starting rate.
Choose floating if you can absorb a higher EMI, plan to repay early, or want to benefit when rates fall.
Check the length of the loan. On a short loan the difference matters less. On a long one, ask whether a fixed period followed by a floating rate is offered, and what the spread is.
Check how the lender passes on changes. A lender that is slow to pass on a fall in the benchmark but quick to pass on a rise costs you money.
Compare offers on the APR, not on the headline rate alone. Fees and the method of resets change the true cost.

Switching later

If you start with one type and it no longer suits you, you have two routes. You can ask your own lender to change the terms, which some lenders allow for a fee set by the lender. Or you can move the loan to another lender through a balance transfer. Add the switching fee and any legal and valuation costs to the comparison before you decide.

Common mistakes

Treating a low starting rate as the rate for the whole loan.
Never asking what the rate is linked to or how often it resets.
Assuming a falling benchmark will lower your rate at once. Check your reset date and the lender's policy.
Ignoring the tenure creeping up after a rate rise. Check your loan statement every year.
Comparing two offers on rate alone, without the fees.

Frequently asked questions

Which is better, a fixed or a floating rate?

Neither is better for everyone. Fixed suits you if you want a steady payment and cannot absorb a rise. Floating suits you if you can bear some risk, may repay early, or want to benefit from falls. Decide using your budget and the length of the loan, not a prediction about rates.

Can I move from a fixed rate to a floating rate?

Often yes, but the terms depend on the lender. Some allow a change for a fee set by the lender, and some do not. You can also move the loan to another lender. Ask for the charge and the new terms in writing before you agree.

Does my EMI always change when the floating rate changes?

Not always. The lender may change the EMI or keep the EMI and change the tenure. Ask which one applies to you, and check your statement after each reset so the tenure does not stretch without your knowledge.

Is there a prepayment charge on a floating-rate loan?

For a floating-rate loan to an individual for a non-business purpose, RBI Directions bar regulated lenders from levying one on loans sanctioned or renewed from 1 January 2026. Business-purpose loans follow separate conditions in the Directions, and older loans can differ. Check your agreement.

What is a semi-fixed or hybrid rate?

It is a loan with a fixed rate for an initial period and a floating rate afterwards. The agreement should say how long the fixed period lasts and what the floating rate is linked to afterwards. Ask for both in writing.

Where can I see current rates?

On the interest rates page of LOANZ 360, which draws rates from live data and dates them. Each lender's offer for you also appears in its Key Fact Statement.
