Does Your Fixed Deposit Interest Rate Stay the Same Until Maturity?

A depositor called us after breaking a three-year deposit eighteen months in. She expected to lose some interest as a penalty. Reasonable.
What she had not expected was that the bank recalculated the entire eighteen months at a different rate. Not her contracted rate minus a penalty. A different rate, applied backwards.
The rate she thought she had been earning had never been hers to keep. It became hers only on the day the deposit ran its full term.
That is the honest answer to this question. Yes, your rate is fixed, and the word fixed is doing less work than most people assume.
At Belong, this is the gap we most often have to close. There is a contracted rate, and there is the rate you actually receive, and five specific events separate them.
The rule, stated plainly
Start with the reassuring part, because it is genuine.
IDBI Bank puts it about as clearly as any bank does. Rates are revised from time to time and made public. Revised rates apply only to renewals and fresh deposits.
Existing deposits continue to receive the contracted rate.
So the Reserve Bank can cut, your bank can slash its card, and your booked deposit is untouched. That protection is real and it is the core promise of the product.
Every exception below involves you changing something, or the product being a different product than you assumed.
π Tip: If you hold your deposit to maturity and change nothing, your rate does not move. That covers the large majority of deposits.
Exception one: you break it early
This is the one that surprises people, because it works backwards rather than forwards.
Breaking a deposit early does not mean earning your contracted rate for the period run, minus a fee. The bank re-prices the whole period.
Interest is recalculated at the rate for the tenure the money actually stayed. That rate is taken as it stood on your booking date.
A penalty is then deducted from it.
Several banks frame it as the lower of two figures. The contracted rate, or the rate applicable to the period actually run, whichever is lower, less the penalty.
Read that carefully. Your three-year rate is irrelevant if the money only stayed eighteen months. You are paid as though you had booked an eighteen-month deposit all along, and then charged for the change.
There is a harsher version for NRE deposits. Break one inside twelve months and no interest is payable at all.
That is not a rate reduction. It is a rate erasure.
Exception two: it is a floating rate deposit
Most depositors do not know these exist, which is exactly why they need naming.
A floating rate term deposit links its interest to an external benchmark. Usually that is the policy repo rate or a treasury bill rate.
The rate resets periodically through the tenure rather than being fixed at booking.
Yes Bank and IDBI Bank have offered these to retail depositors. State Bank of India has run a floating rate variant on bulk term deposits.
So the product exists and sits alongside ordinary fixed deposits. Its defining feature is precisely the thing this article is about.
Whether it suits you depends on your rate view. In a rising environment a floating deposit captures the increase. In a falling one it hands back the very certainty you bought a deposit for.
Commentary when these were marketed was cautious. Advisers pointed out that a floating deposit is a poor choice when rates are expected to fall.
We would put it differently. If your reason for holding a deposit is certainty, a floating rate deposit is not that instrument. Choose it deliberately or not at all.
π Tip: Check whether the product you are being sold is a fixed or floating rate term deposit. The names are similar and the behaviour is not.
Exception three: it matures and nobody claims it
Covered more fully elsewhere, but it belongs on this list.
Once a deposit matures and the proceeds are neither paid out nor renewed, the money is overdue. Reserve Bank instructions since July 2021 mean it earns the savings account rate or the contracted rate, whichever is lower.
So the contracted rate survives right up to the maturity date and then stops applying. Doing nothing is itself a rate change.
Exception four: a reverse sweep breaks a tranche
If your deposits were created by a sweep or flexi arrangement, they are ordinary deposits with an automatic trigger attached.
When your savings balance falls short, the bank breaks part of the deposit stack to cover it. That broken portion is a premature withdrawal, and exception one applies to it.
The deposits left intact keep their rates. Only the units actually broken are re-priced.
For NRE sweep arrangements this compounds unpleasantly. The broken tranche is often the newest one. That makes it the one most likely to sit inside the twelve month window.
Exception five: it renews
The obvious one, and still the most common in practice.
At maturity your deposit renews at whatever rate the bank publishes that day, for whatever tenure the instruction specifies. Your old rate does not carry across.
This is not a rate change to your deposit. It is a new deposit that looks like the old one on your statement.
The distinction matters because it means the moment to act is the maturity date, not some point during the tenure.
The ceiling on NRI deposit rates
Here is a rule that explains something NRIs frequently ask about, and it rarely appears in consumer writing.
Indian Bank sets it out plainly in its published deposit terms. Interest rates on NRE and NRO deposits cannot be higher than those offered on comparable domestic rupee term deposits.
That is a regulatory ceiling, not a bank preference. It is why you never see a premium for being a non-resident depositor.
Two related points from the same terms are worth knowing.
The additional rate banks pay their own staff does not extend to NRE and NRO deposits. Nor, at most banks, does the senior citizen premium.
And where a loan or overdraft has been taken against an NRE term deposit, pre-closure is not permitted at all. The deposit is locked, not merely penalised.
So an NRI deposit rate is capped at the domestic equivalent and excluded from the common enhancements. It can also be frozen entirely if pledged.
Our guides on FCNR deposits and high FCNR deposit rates cover the foreign currency alternative, where the pricing logic differs.
Why banks re-price rather than penalise
Worth understanding the logic, because it makes the rule feel less arbitrary.
A bank priced your three-year rate on the basis that it had your money for three years. That funding certainty is what the higher rate paid for.
Take the money back at eighteen months and the bank never received what it paid for. Re-pricing to the eighteen-month rate restores the original bargain.
The penalty on top covers the disruption of an unplanned outflow.
Seen that way, it is not a punishment. It is the bank unwinding a trade you exited early, which is roughly how any fixed-term contract behaves.
What genuinely is fixed
Worth restating, because the exceptions can leave the wrong impression.
If you book a deposit and hold it to term, four things do not move. The principal, the interest rate, the tenure, and the maturity date.
No policy decision reaches into a live deposit. No bank revision applies retrospectively. That is the whole point of the instrument, and it is honoured.
What changes is never the contract. It is your relationship to it.
That is why compounding inside a cumulative deposit is so dependable. The rate that compounds is locked, so the outcome is knowable on day one.
If you are an NRI
Three practical points.
Your rate is capped at the domestic comparable.
Shopping between banks still helps, but there is no non-resident premium to find.
Breaking early is costlier than for a resident.
The twelve month NRE rule turns an early exit into a total loss of interest on that deposit.
Pledging locks the rate and the money.
If you have borrowed against a deposit, pre-closure may not be available at all.

If you are a resident Indian
Your version is simpler, with one warning.
Check whether any deposit you hold is a floating rate product. If it is, your rate is not fixed and the article's premise does not apply to it.
Beyond that, treat the contracted rate as genuinely safe and focus your attention on maturity dates instead.
One comparison worth making. Deposit interest and capital gains are taxed differently, which our note on capital gains versus interest income sets out. A fixed rate does not mean a fixed post-tax outcome.

Mistakes we see
Assuming early exit means contracted rate minus a fee.
The whole period is re-priced instead.
Buying a floating rate deposit without noticing.
The defining feature is that the rate moves.
Treating the maturity date as unimportant.
It is the only date on which your rate can legitimately change.
Pledging a deposit and assuming you can still break it.
Where a loan is outstanding, pre-closure may be barred.
Expecting a better rate as an NRI.
Rates are capped at the domestic comparable.
Watching rate news while holding a live deposit.
Nothing announced today reaches money already committed.
What happens if you ignore this
The typical cost arrives at exit rather than during the term.
Someone books a long deposit for a good rate, then needs the money partway. The return turns out far below what the statement implied.
The gap between contracted and realised was always there, waiting for a trigger.
The time value of money argument for locking a long tenure is sound. It only holds if you can actually leave the money alone.
Match the tenure to the need and the exceptions never fire.
Decision clarity
If you can hold to maturity, your rate is genuinely fixed and you can stop worrying about rate news.
If there is real doubt about the tenure, book shorter. A lower rate you keep beats a higher rate that gets re-priced on exit.
If you are shown a floating rate deposit, decide whether you want certainty or upside. You cannot have both.
If you have pledged a deposit, confirm whether pre-closure is even available before you plan around it.
If you are an NRI, let the twelve month NRE rule shape your tenure choices before the rate card does.
Frequently asked questions
Can a bank change my FD interest rate after I book it?
No. Revised rates apply only to fresh deposits and renewals. An existing deposit continues at its contracted rate for the full tenure.
What rate do I get if I break my FD early?
The rate for the period the money actually stayed, as it stood on your booking date. Or your contracted rate, whichever is lower. A penalty is then deducted.
Do RBI rate cuts affect my existing fixed deposit?
No. Policy changes affect new deposits and renewals. Money already committed is unaffected in either direction.
Are there fixed deposits where the rate does change?
Yes. Floating rate term deposits link the rate to a benchmark such as the repo rate.
It resets through the tenure. Some banks offer these alongside ordinary fixed rate deposits.
Do NRIs get higher deposit rates than residents?
No. Published bank terms state that rates on NRE and NRO deposits cannot exceed those on comparable domestic rupee term deposits.
Where this leaves you
Yes, your rate stays the same. The contract is honoured and nothing announced later reaches money already placed.
What moves is what you receive, and only when you act.
Break it early and the period is re-priced. Let it mature unclaimed and the overdue rule takes over. Renew it and you have a new deposit at a new rate.
The single habit that protects you is matching tenure to need at the point of booking. Do that and none of the exceptions in this article will ever apply to you.
