All About Certificates of Deposit (CDs).
The Global Name for a Locked Term Deposit, Lived in India as the Fixed Deposit.
Published as on 9 July 2026
A Certificate of Deposit is what most of the world calls a locked-term bank deposit. In India, that instrument is experienced almost universally as the Fixed Deposit, or FD, so this guide covers the FD as India's CD equivalent. You hand a bank your money for a chosen tenure, from 7 days to 10 years, and it promises a fixed, pre-declared rate, typically 6-8% a year. Your deposit is insured by the DICGC up to Rs 5 lakh per bank. The appeal is certainty: you know exactly what you will receive. The cost is flexibility, and a return that, after tax and inflation, often barely stands still. This is a guide to how the CD/FD works, what it really risks, how it is taxed, and the mistakes that quietly cost depositors.

Executive Summary · 7 Findings
A Certificate of Deposit is a contract in which you trade time flexibility for return certainty. In India this instrument is the Fixed Deposit, and understanding it as a stability tool, not a growth engine, resolves almost every confusion that surrounds it.
This article covers what the CD/FD is and how it works, where it fits in a portfolio and how it compares to other savings options, the risks that survive even without volatility, how the interest is taxed, how rate cycles affect you, the five common mistakes, and a framework for deciding whether it is right for you.
Key Findings
In India, the CD is lived as the Fixed Deposit.
A Certificate of Deposit is the American name for a locked-term bank deposit. The Indian retail equivalent is the Fixed Deposit: a time-bound deposit with a bank or NBFC where you agree to keep money locked for a chosen tenure in exchange for a fixed, pre-declared rate. The product works the same way, and this guide uses Indian terminology throughout.
The rate is locked upfront and the maturity is fixed.
Book at 7% and you earn 7%, even if rates later climb to 8% or fall to 6%. You choose the tenure, from 7 days to 10 years, and the money stays locked until that date. There is no mark-to-market: your statement shows the same value every day. The return is fully known before you commit.
Interest is taxed at your slab, so the headline rate is not what you keep.
FD interest is added to your income and taxed at your income-tax slab rate. In the 30% bracket, a 7% FD returns 4.9% after tax. Banks deduct TDS at 10% (20% without PAN) once annual interest crosses Rs 50,000, or Rs 1 lakh for senior citizens, per FY 2025-26 rules.
Deposits are insured, but only up to Rs 5 lakh per bank.
The DICGC, an RBI subsidiary, insures deposits up to Rs 5 lakh per depositor per bank, covering principal and interest across all account types combined. Keep Rs 10 lakh in one bank that fails, and Rs 5 lakh is at risk. "Bank FD equals zero risk" is a myth; spreading large sums across banks is the real safeguard.
It trades flexibility for predictability, and breaking early has a cost.
Premature withdrawal usually cuts 0.5-1% off the interest rate, and withdrawing within 7 days can mean zero interest. Some digital and Small Finance Banks now offer no-penalty FDs. Before breaking, check whether a loan against the FD is cheaper than the penalty math.
No volatility does not mean no risk.
FDs face inflation risk (7% pre-tax against 6% inflation leaves almost nothing real, negative after tax), reinvestment and opportunity-cost risk (locking low before rates rise, or missing equity's long-run returns), and liquidity risk (early access costs). A steady statement conceals real erosion of purchasing power.
FDs belong in the capital-preservation layer, not the growth layer.
They suit known 1-5 year goals and retirees needing stable income, not a 30-year-old saving for retirement, where inflation and tax will erode real returns. For long-term wealth, pair FDs with equity and other growth assets. Once you accept their structural role, most FD confusion disappears.

The Opening
A Certificate of Deposit, or CD, is the name Americans give to a locked-term bank deposit. In India, the very same idea is experienced almost universally as the Fixed Deposit, or FD. So while the title of this guide says "Certificate of Deposit", the instrument you will actually walk into a branch and open is the Fixed Deposit, and this article covers the FD as India's CD equivalent, using Indian terminology throughout.
The mechanics are identical in spirit. A Fixed Deposit is a time-bound deposit with a bank or NBFC where you agree to keep money locked for a specific period, the tenure, in exchange for a fixed, pre-declared interest rate. The bank uses your money to fund loans, and in return pays you more than a savings account would. You are, in effect, lending the bank money against a written promise to return your principal plus interest on a specific future date.
In India these deposits are regulated by the Reserve Bank of India, and rates are set by individual banks in line with the RBI's repo-rate policy. As of early 2026, typical FD rates run from 6% to 8% per annum, with senior citizens earning an extra 0.25% to 0.75%. The tenure is yours to choose, anywhere from 7 days to 10 years.
"What Americans call a Certificate of Deposit, we in India call a Fixed Deposit. The product is the same: a locked-term deposit offering guaranteed returns. The name changes at the border; the bargain does not."
The India Framing
What the CD/FD is not: it is not a bond you can trade, it is not completely risk-free, it is not an inflation-beating investment, and it is not flexible. It is a structure that suits a specific job, preserving capital while earning a predictable, modest return, for a specific investor with a specific time horizon.

Part I
What It Is and How It Works
The locked-term deposit, why banks offer it, and the five behaviours that define how a CD/FD actually works.
Part I: What It Is and How It Works · Page 4
The Locked-Term Bargain
A Fixed Deposit is a time-bound deposit with a bank or NBFC. You agree to keep a sum locked for a specific tenure, and in return the bank pays a fixed, pre-declared interest rate, higher than a savings account. The simplest way to picture it: you are lending money to the bank against a written promise that it will return your principal plus interest on a set future date.
Banks want this money because it is stable funding. Unlike a savings account, where balances move daily, an FD stays put, letting the bank match a 3-year deposit against a 3-year loan and plan its lending with confidence. For you, the deposit delivers a higher rate than savings (roughly 6-8% against 3-4%), certainty of return, disciplined saving through the lock-in, and capital preservation within the insurance limit.
Why It Is Not a Bond
An FD is not a bond. You cannot sell it to someone else or trade it on an exchange (a handful of banks offer transferable FDs, but these are rare). Unlike a bond, there is no daily price and no secondary market, which is precisely why it never fluctuates in value, and also why liquidity comes only through premature withdrawal, at a cost.
"You are saying: Bank, I will give you my Rs 5 lakh for 3 years. In return, promise me exactly 7% per year. I will not ask for it back, and you guarantee the return. The bank says: deal."
The Contract in One Exchange
How a CD/FD Actually Behaves
Five characteristics define the instrument:
1. The Rate Is Locked Upfront
Book at 7% and that is what you get, even if rates rise to 8% next month. It works both ways: if rates fall, you are protected at the higher rate you secured.
2. The Maturity Date Is Defined
You choose the tenure, 1 year, 3 years, 5 years, and the money stays locked until that date.
3. Premature Withdrawal Carries a Penalty
Break early and you earn interest only for the period the money stayed, minus a penalty of typically 0.5-1% below the applicable rate. Withdraw within 7 days and you may get zero interest.
4. There Is No Mark-to-Market
Unlike bonds or debt funds, your FD statement shows the same value every day. There is no price change to watch.
5. The Return Is Known Upfront
You can compute exactly what you will receive at maturity, using simple or compound interest, before you commit a single rupee.
An RBI note on breaking FDs: all scheduled commercial banks must offer premature withdrawal on FDs up to Rs 1 crore. Above Rs 1 crore, banks may offer non-callable FDs with no premature withdrawal, a regulation effective October 2023.
Part II
Where It Fits
The capital-preservation layer, how the FD compares to other savings options, and the line between normal and unrealistic expectations.
Part II: Where It Fits · Page 6
Money in Layers
Think of your money in four layers. Layer 1, immediate liquidity: a savings account or liquid fund you can reach within 24 hours. Layer 2, capital stability: this is where FDs belong, money you will not need for 1-5 years, kept to preserve capital while earning a predictable return. Layer 3, income generation: bonds and certain debt funds. Layer 4, growth: equity funds and stocks for long-term wealth.
The critical point: FDs are not designed for growth. They protect what you already have while earning a modest, guaranteed return. If you are planning to buy a car in 3 years and have Rs 3 lakh, an FD makes sense, you will know you will have roughly Rs 3.7 lakh at 7%. But if you are 30 and saving for retirement at 60, FDs alone will not be enough; inflation will eat the returns.
FD vs Other Savings Options
On Rs 1 lakh for a year: a savings account at 4% grows to Rs 1,04,000 but stays fully withdrawable; an FD at 7% grows to Rs 1,07,000 but is locked; a debt fund averaging 7.5% might reach Rs 1,07,500 or dip to Rs 1,06,500 with markets, but you can exit anytime. Since the 2023 Finance Act removed indexation, standard debt funds are taxed at slab rates too, so their tax treatment is now nearly identical to FDs.
The Comparison Table
| Feature | Savings A/c | FD | Debt Fund |
|---|---|---|---|
| Liquidity | High | Low | High |
| Return | 3-4% | 6-8% | Variable |
| Price Volatility | None | None | Present |
| Tenure Fixed | No | Yes | No |
| Tax | Slab | Slab | Slab* |
| DICGC Cover | Rs 5L | Rs 5L | None |
*Since the 2023 Finance Act, standard debt funds lost indexation and are taxed at slab rates. ADWIZR analysis.
Normal vs Unrealistic Expectations
Reasonable to Expect
A predictable return you will earn exactly as promised; low volatility with a stable principal; a yield modestly above savings accounts; and an early-withdrawal penalty if you break the deposit.
Unrealistic to Expect
Meaningful outperformance versus other fixed income; high real returns after inflation and tax; rate-timing arbitrage as if trading stocks; or liquidity without cost. Accessing money early always carries a price.
Good Fit
Near-term known expenses (a car, school fees) and retirees needing stable, predictable income from a capital base they must preserve.
Poor Fit
Long-horizon wealth building, where FDs alone underperform inflation plus tax and a category mismatch quietly compounds against you.
Part III
The Real Risks
A steady statement is not a safe one. Inflation, reinvestment, and liquidity risks survive the absence of volatility.
Part III: The Real Risks · Page 8
No Volatility Is Not No Risk
Inflation and real-return risk
This is the quiet killer. At 7% pre-tax and 6% inflation, your real return is barely 1%, and after tax it turns negative. In the 30% bracket, a 7% FD becomes 4.9% post-tax; against 6% inflation, purchasing power falls by 1.1% a year. The statement never drops, but what your money can buy does.
Reinvestment and opportunity-cost risk
Lock in low before rates rise and you are stuck: book Rs 5 lakh at 6.5% in January, watch new FDs offer 7.5% in June, and you forgo Rs 5,000 a year. There is also the wider opportunity cost: if equities deliver 12% over the long run and your FD gives 7%, you have given up 5% of potential return in exchange for certainty.
Liquidity and penalty risk
An FD is not liquid without cost. Breaking early cuts 0.5-1% off the rate, forfeits compounding, and, within 7 days of booking, can mean zero interest. If you may need the money, an FD is the wrong home for it, no matter how attractive the headline rate looks.
Bank credit risk
"Bank FD equals zero risk" is wrong. Deposits carry credit risk, which is exactly why DICGC insurance exists. If your bank fails and you hold Rs 10 lakh there, only Rs 5 lakh is insured; the remaining Rs 5 lakh joins the liquidation queue. Always spread large sums across multiple banks.
The "no volatility" illusion
Because an FD never shows a red day, it feels safe. But the three risks above, inflation erosion, opportunity cost, and credit exposure, are all present at once. A calm chart is not the same as a protected outcome; it simply hides where the erosion is happening.
The Concentration Trap
Putting Rs 10 lakh into one bank for the convenience of a single relationship exposes half of it. DICGC covers Rs 5 lakh per bank, so two banks at Rs 4.5 lakh each are fully covered while one bank at Rs 9 lakh is not.
Part IV
Taxation and Insurance
Interest taxed at your slab, TDS thresholds and mechanics, and the Rs 5 lakh DICGC safety net that has real limits.
Part IV: Taxation and Insurance · Page 10
Taxed at Your Slab
The rule is simple and unforgiving: FD interest is added to your total income and taxed at your income-tax slab rate. There is no special treatment, no exemption, and, for standard FDs, no indexation. What you keep depends entirely on your bracket.
How TDS Works
Banks deduct TDS once annual FD interest exceeds Rs 50,000 for those under 60 (effective 1 April 2025), or Rs 1 lakh for senior citizens. The rate is 10% with PAN, 20% without. TDS is a withholding, not the final tax; you reconcile the balance in your ITR.
A worked example. You hold Rs 10 lakh in FDs at 7%, earning Rs 70,000 interest, with a total income of Rs 15 lakh (15% bracket). The bank deducts Rs 7,000 TDS (10%). Your actual tax owed is Rs 10,500 (15% of Rs 70,000), so you pay another Rs 3,500 at filing. Post-tax interest is Rs 59,500, a real return of 5.95%, not the 7% on the poster.
Tax-Saving FDs (Section 80C)
A 5-year tax-saver FD qualifies for the Rs 1.5 lakh deduction under Section 80C (Old Regime only), with a compulsory 5-year lock-in and no premature withdrawal. The principal earns the benefit; the interest is still taxed at your slab. In the 30% bracket, Rs 1.5 lakh invested saves Rs 45,000 upfront, against roughly Rs 18,000 of tax on the interest over five years.
The DICGC Safety Net
The Deposit Insurance and Credit Guarantee Corporation, an RBI subsidiary, insures bank deposits up to Rs 5 lakh per depositor per bank, covering principal plus interest across all account types, savings, FD, RD, and current, combined across every branch of the same bank.
Covered
Savings accounts
Fixed and recurring deposits
Current accounts, up to Rs 5L total
Not Covered
Deposits in NBFCs (only banks qualify)
Government and inter-bank deposits
Anything above Rs 5 lakh per bank
The limit bites in practice. Hold Rs 3 lakh in an SBI savings account, Rs 4 lakh in an SBI FD, and Rs 2 lakh in another SBI FD, and your Rs 9 lakh in SBI is insured for only Rs 5 lakh; Rs 4 lakh is exposed. Split it, Rs 4.5 lakh in SBI and Rs 4.5 lakh in HDFC, and both are fully covered.
The Practical Safety Rule
Never keep more than Rs 5 lakh, across all account types, in any single bank. There has been discussion of raising the limit to Rs 8-12 lakh, but as of early 2026 the official cover remains Rs 5 lakh per depositor per bank.
Payout mechanics: if a bank is placed under moratorium, DICGC pays the insured amount within 90 days. Anything above Rs 5 lakh becomes part of the bank's liquidation, where recovery is uncertain, another reason to diversify banks rather than chase a marginally higher rate.
Part V
Rates, Mistakes, and the Decision
How rate cycles move against and for you, the five mistakes depositors keep making, and the four-step check to decide if it fits.
Part V: Rates, Mistakes, and the Decision · Page 12
How Rate Cycles Affect Your FD
An FD is a rate snapshot, not a floating instrument. When you book, you are betting that today's rate is acceptable for the tenure you chose. When rates rise, existing FDs locked lower look less attractive and new ones pay more. When rates fall, your earlier lock-in looks smart. When rates are stable, the FD simply delivers its predictable carry.
Book Rs 5 lakh at 6.5% for 2 years and watch rates climb to 7.5%, and the opportunity cost is Rs 5,000 a year. Book at 7.5% for 3 years just before a cut to 6.5%, and you gain Rs 5,000 a year. Because you cannot know which way rates will move, many investors use FD laddering, splitting money across maturities so a portion renews each year at prevailing rates.
The Five Common Mistakes
Locking emergency funds in long-tenure FDs
Put Rs 3 lakh in a 5-year FD, then need Rs 1 lakh in six months, and you pay a penalty and lose compounding. Keep 3-6 months of expenses in a savings account or liquid fund; lock only money you are sure you will not need.
Breaking FDs without the penalty math
Break a 2-year FD after one year and the applicable 1-year rate (say 6.5%) minus a 1% penalty leaves 5.5%, well below the 7% you expected. Before breaking, check whether a loan against the FD, usually at the FD rate plus 1-2%, is cheaper.
Overweighting FDs in rising-rate cycles
Lock everything into a 5-year FD at 6.5% just before rates settle at 7.5%, and your money underperforms for 4.5 more years. In uncertain rate environments, ladder across 1, 2, and 3-year FDs so one matures and renews each year.
Over-valuing tiny rate differences
Bank A at 7.1% versus Bank B at 7.25% is a difference of just Rs 750 a year on Rs 5 lakh. Chasing 0.15% rarely justifies worse service or a distant branch. Tax efficiency, DICGC diversification, and overall allocation matter far more.
Assuming no volatility means no risk
A flat statement hides inflation erosion, opportunity cost, and credit exposure. A 7% FD at 30% tax is 4.9% post-tax; against 6% inflation, that is a real return of minus 1.1%. Stability is not the same as safety.
The Decide-If-Right Check
Step 1 · Liquidity
Can you confidently not touch this money for the full tenure? If no, an FD is misaligned; use a savings account, liquid fund, or short-duration debt fund instead.
Step 2 · Return Clarity
Is the rate premium meaningful after tax and against savings rates? A 7% FD at 30% tax nets 4.9%; if savings pay 3.5%, the premium for locking up is only 1.4%. Worth it for some, not for others.
Step 3 · Portfolio Role
Is this money for a near-term known expense or capital preservation? Then an FD fits. If the goal is long-term growth, it is a category mismatch that inflation and tax will punish.
Step 4 · Rate Context
Are rates rising, falling, or stable? If you expect a fall, locking 7%-plus for 3-5 years makes sense; if you expect a rise, keep tenures short or ladder. FDs are not timing tools, but tenure choice still matters.
Part VI
The Verdict
Where the CD/FD belongs, and the clean mental model that resolves the confusion.
Part VI: The Verdict · Page 14
The Assessment
A Fixed Deposit, India's version of the Certificate of Deposit, is a time-bound bank deposit that offers guaranteed returns in exchange for locking your money for a defined period. It belongs in the capital-preservation layer of a portfolio, not the growth layer. It removes market volatility but limits liquidity and rarely beats inflation once tax is counted. Your principal and interest are insured up to Rs 5 lakh per bank by the DICGC.
Use it for short-to-medium goals, 1 to 5 years, where you need certainty and can afford to lock money away. For long-term wealth building, combine FDs with equity and other growth assets. Once you accept that the FD is a stability tool rather than a growth instrument, most of the confusion around it simply dissolves.
"A Fixed Deposit is a contract where you trade time flexibility for return certainty. That is the entire product in one sentence, and everything else, tenure, penalty, tax, insurance, is a detail hanging off that trade."
The Clean Mental Model
For the 1-5 year, certainty-first saver: the FD does its job well. For the long-horizon wealth builder: it is a supporting player at best, and a drag if it becomes the whole plan.
ADWIZR · July 2026
Decision Rules
Match tenure to the goal
Lock only money you are sure you will not need before maturity. Keep 3-6 months of expenses liquid outside any FD.
Diversify banks under Rs 5 lakh
Never hold more than Rs 5 lakh, across all account types, in a single bank. Spread larger sums so every rupee stays DICGC-insured.
Judge returns after tax, not on the poster
Convert the headline rate to a post-tax, post-inflation number before committing. A 7% FD in the 30% bracket is 4.9%, and often negative in real terms.
Ladder when rates are uncertain
Split across maturities so a portion renews each year. It softens reinvestment risk without pretending you can time the rate cycle.
The Bottom Line
The Certificate of Deposit, lived in India as the Fixed Deposit, trades flexibility for predictability. It is excellent for known 1-5 year goals and for retirees needing steady income, insured to Rs 5 lakh per bank. But it rarely beats inflation after tax, so treat it as the stability layer of a portfolio, diversify your banks, judge the rate after tax, and never mistake a flat statement for a risk-free one.

Key Terms & Definitions
Certificate of Deposit (CD)
The American name for a locked-term bank deposit paying a fixed rate over a set maturity. In India, the retail equivalent that ordinary savers actually open is the Fixed Deposit, which this guide treats as the CD's Indian form.
Fixed Deposit (FD)
A time-bound deposit with a bank or NBFC where money is locked for a chosen tenure, from 7 days to 10 years, in exchange for a fixed, pre-declared interest rate, typically 6-8% per annum in India.
Tenure
The fixed period for which an FD is locked, ranging from 7 days to 10 years. The money remains committed until the maturity date, and breaking it early triggers a penalty.
DICGC
The Deposit Insurance and Credit Guarantee Corporation, an RBI subsidiary that insures bank deposits up to Rs 5 lakh per depositor per bank, covering principal and interest across all account types combined.
TDS (Tax Deducted at Source)
Tax the bank withholds on FD interest once it exceeds Rs 50,000 a year (Rs 1 lakh for senior citizens), at 10% with PAN or 20% without. It is a withholding, reconciled against final tax in your ITR, not a separate charge.
Premature Withdrawal Penalty
A reduction of typically 0.5-1% in the applicable interest rate when an FD is broken before maturity. Withdrawing within 7 days of booking can mean zero interest; some banks now offer no-penalty FDs.
FD Laddering
A strategy of splitting money across FDs of different maturities so that one matures each year and can be renewed at prevailing rates, reducing reinvestment risk in an uncertain rate cycle.
Tax-Saving FD (Section 80C)
A 5-year FD qualifying for the Rs 1.5 lakh Section 80C deduction under the Old Tax Regime, with a compulsory lock-in and no premature withdrawal. The principal earns the deduction; the interest is still taxed at slab rates.
