One of the first choices on a home loan form is the rate type: fixed or floating. Here is what each means, in plain words.
Floating rate: moves with the market
A floating rate changes over time. Since October 2019, RBI has required banks to link new floating-rate retail loans, including home loans, to an external benchmark, such as RBI's repo rate. Your rate is the benchmark plus a fixed extra amount called the spread.
When the benchmark goes up, your rate goes up at the next reset. When it goes down, your rate goes down too.
Fixed rate: steady, for a while
A fixed rate stays the same for a period. In India, many "fixed" home loans are fixed only for some years and then switch to floating. Read the sanction letter to see how long the fixed period really is.
Hybrid loans
Some loans start fixed and then become floating. Mark the switch date in your calendar so it does not surprise you.
What happens when rates change
If a floating rate rises, the lender can increase your EMI, extend your loan term, or do a bit of both. RBI has asked lenders to explain the change clearly, give you options, and let you switch to a fixed rate at reset, as per their policy.
Extending the term keeps the EMI the same but adds interest over time. If your budget allows, a slightly higher EMI is usually cheaper overall.
Which suits a first-home buyer?
- Floating suits people who can handle some change in EMI and want to benefit when rates fall. Prepayment penalties are not allowed on floating-rate loans to individuals.
- Fixed suits people who want a steady EMI for budgeting, and accept that the rate may be higher and prepayment may carry charges.
Switching later
You can ask your lender to move you to a lower rate, often for a fee, or move your loan to another lender. Compare all costs before switching.
The words on your sanction letter, explained
- Benchmark. The outside rate your loan is tied to. For many bank loans it is RBI's repo rate. Your lender must tell you which one it uses.
- Spread. The extra percentage the lender adds on top of the benchmark. Under RBI's 2019 circular, the credit risk part of the spread should not rise unless your credit profile changes materially, as agreed in the contract.
- Reset. The date your rate is recalculated after a benchmark change. RBI requires the rate on external-benchmark loans to be reset at least once every three months.
- Tenure. The number of months you will pay. Rate changes can quietly stretch it.
A worked example: what a 0.5% rise really costs
Illustrative figures only, not an offer from any lender. Say you borrow ₹50 lakh for 20 years at 8.5% on a floating rate. The EMI works out to about ₹43,391, and the total interest over 20 years is about ₹54.1 lakh.
Now say the rate rises to 9.0%. The lender can respond in two main ways:
| Option | Monthly EMI | Loan length | Extra interest over the loan |
|---|---|---|---|
| Raise the EMI, keep 20 years | About ₹44,986 (₹1,595 more) | 20 years | About ₹3.8 lakh |
| Keep the EMI, stretch the term | ₹43,391 (unchanged) | About 22 years 4 months | About ₹11.8 lakh |
The arithmetic is plain: stretching the term feels painless each month, but in this example it costs about three times more in interest. That is why it is worth asking your lender which option it has applied after each reset, and choosing the higher EMI if your budget allows.
The figures assume the new rate applies from the start of the loan, to keep the sums simple. In real life a reset applies to the balance left at that date, but the lesson is the same.
How to choose, step by step
- Find your comfortable EMI. Work out the most you could pay each month even in a tight year, after rent or maintenance, insurance and savings.
- Test a rate rise. Add 1% to the rate you are offered and recalculate. If that EMI still fits, floating risk is manageable for you.
- Read the fixed period. If a "fixed" rate lasts three or five years, note the date and the rule for what happens after.
- Compare the full cost. Look at processing fees, any conversion fees and, for fixed loans, prepayment terms. RBI's Key Facts Statement rules require lenders to give you these costs in one standard sheet before you sign.
- Plan prepayments. If you expect bonuses, a floating loan lets an individual prepay without a penalty, which can cut years off the loan.
Common mistakes on a first loan
- Comparing only the headline rate. Two loans with the same rate can differ in fees, spread and reset dates.
- Not noticing the tenure creep. Check your loan statement once a year. If the remaining months have grown, ask why.
- Assuming "fixed" means for 20 years. Many are fixed for a few years only.
- Ignoring the annual interest certificate. You need it for tax, and it shows how much of your EMI is going to interest.
- Switching without counting costs. A lower rate elsewhere can be eaten up by fees, legal charges and stamp duty on the new mortgage paperwork.
Prepaying: the quiet way to beat rate rises
Whatever rate type you choose, small prepayments make a big difference. Here is the logic in plain words. In the early years of a loan, most of each EMI goes to interest, because interest is charged on the large balance still owed. Any extra amount you pay goes straight to reducing that balance, so every later month's interest is calculated on a smaller number.
Illustrative figures only. On the ₹50 lakh, 8.5%, 20-year loan above, the interest in the very first month is ₹50,00,000 × 8.5% ÷ 12, which is about ₹35,417. Only about ₹7,974 of that first ₹43,391 EMI reduces your loan. That is why a lump sum paid early, such as part of an annual bonus, cuts total interest far more than the same amount paid near the end.
Before you prepay, check three things:
- Charges. For a floating-rate loan taken by an individual for a purpose other than business, RBI does not allow foreclosure or prepayment penalties. Fixed-rate loans may carry them, so read the terms.
- What gets reduced. Ask the lender to reduce the remaining tenure rather than the EMI, if your budget allows. It usually saves more interest.
- Your safety net. Do not prepay so much that you have no emergency fund left. Six months of expenses is a sensible cushion to keep aside first.
When a fixed rate can make sense
A fixed rate is not a bad choice. It suits a buyer whose budget has very little room, such as a single-income household in the first years of a loan, or someone who simply sleeps better knowing the EMI will not move. The trade-off is that you may pay a higher rate for that certainty and lose some flexibility. Ask the lender, in writing, what rate applies once the fixed period ends, and whether you can switch earlier and at what cost.
Talking to your lender after a reset
When your rate changes, you should receive a communication about it. If you do not, ask for one. A simple message works: "Please confirm my new rate, the new EMI and the remaining tenure after the latest reset, and the options available to me." Keep the reply with your loan papers.
A quick checklist before you sign
- Benchmark name and current value written down
- Spread written down
- Reset frequency and next reset date
- What the lender does after a rate rise: EMI, tenure or both
- Fixed period length, if any, and the rate after it
- Prepayment and switching charges
- Key Facts Statement received and read
