what is the real return on a fixed deposit after tax and inflation

For someone in the 30% slab, a 7% FD returns about 4.9% after tax, and with inflation near 5.5% the real return is roughly −0.6% — the rupee balance grows while purchasing power slips slightly. FD interest is taxed at your slab rate rather than at capital gains rates, so the headline number always overstates what you keep. That is a trivial price for certainty on money needed in eighteen months, and a serious drag on money needed in eighteen years.

is TDS on FD interest the final tax I owe

No. Banks deduct TDS above a threshold, but FD interest is taxable at your full slab rate, so anyone in a slab above the TDS rate still owes the balance at the time of filing. Assuming TDS has settled the liability is one of the most common and expensive surprises in Indian household finance.

the risk that a maturing deposit can only be renewed at a lower rate is called

Reinvestment risk. A five-year FD at 7.5% maturing into a 5.5% rate environment means the next five years earn considerably less on the same money. Laddering — splitting the amount across several maturities so something matures regularly — blunts it, because you are never fully committed to whatever rate happens to exist on one particular day.

which small savings schemes are tax free in India

Sukanya Samriddhi Yojana and PPF are fully tax-free. Bank FDs and RDs, SCSS, POMIS and five-year tax-saving FDs all have their interest taxed at your slab rate. For someone in the 30% bracket that difference in treatment is worth roughly three percentage points a year — larger than the gap between any two FD rates you will spend an afternoon comparing.

do senior citizens get a higher FD rate

Banks generally offer senior citizens an extra 0.25–0.50% on fixed deposits, along with a higher threshold before interest attracts TDS. SCSS is separately available from age 60, with a five-year term that can be extended. For a retired household these products are doing the job they are actually good at: preserving capital and producing predictable interest.

Fixed deposits and small savings schemes

Fixed deposits remain where most Indian household savings sit, and the usual advice — "FDs are bad, buy equity" — is too crude to be useful. FDs are excellent at one job and poor at another, and the whole question is which job you are asking them to do.

The real return

The headline rate is not what you earn. Interest is taxed at your slab rate, and inflation takes another bite. What remains is the real, post-tax return — the only number that describes whether your purchasing power grew.

Worked example

A 7% FD for someone in the 30% slab

₹10,00,000 for one year

Headline rate₹70,000 of interest7.0%

Less tax at 30%Interest is taxed at your slab, not at capital gains rates−₹21,000

Post-tax return₹49,0004.9%

Less inflation at 5.5%What the same basket now costs−5.5%

Real returnPurchasing power slightly lower than a year ago≈ −0.6%

The deposit "earned" ₹49,000 and bought less than it could have a year earlier. This is not an argument against FDs — it is an argument against using them for long-horizon goals, where a small negative real return compounds into a large shortfall.

Scheme	Who it suits	Lock-in	Tax treatment
Bank FD / RD	Anyone; short-horizon money	Flexible, penalty on early exit	Interest at slab rate
SCSS	Age 60+	5 years, extendable	Interest at slab rate; deduction on investment
SSY	Parents of a girl child under 10	Until 21 / marriage	Fully tax-free
PPF	Anyone	15 years	Fully tax-free
POMIS	Those wanting monthly income	5 years	Interest at slab rate
Tax-saving FD	Those needing a deduction	5 years, no early exit	Interest at slab rate

Two things people get wrong

TDS and reinvestment

1
TDS is not the tax
Banks deduct TDS above a threshold, but the tax you owe is at your full slab rate. If your slab is higher than the TDS rate, the balance is payable at filing. Assuming TDS settles it is a common and expensive surprise.
2
Interest is taxable as it accrues
On a cumulative multi-year FD, interest is generally taxable each year as it accrues — not only when you receive the lump sum at maturity.
3
Reinvestment risk is real
A 5-year FD at 7.5% maturing into a 5.5% rate environment means the next five years earn considerably less. Locking a good rate for longer when rates are high is the mirror image of the bond lesson.
4
Laddering solves both
Split the money across several maturities. Something matures regularly, so you are neither fully locked in nor fully exposed to whatever rate exists on one particular day.

Check yourself

A 7.5% FD, a 30% tax slab and 6% inflation. What is the approximate real return?

Simple bhasha mein

FD ka asli return

FD 7% de rahi hai, sun ke achha lagta hai. Par 30% slab mein ho toh haath mein 4.9% aaya, aur mehngai 5.5% thi. Matlab saal bhar baad paisa toh badha, par kharidne ki taakat kam ho gayi. FD 1 saal ke kaam ke liye best hai; 15 saal ke sapne ke liye nahi.

What to remember

Judge deposits by real post-tax return, not the headline rate.
FDs preserve capital over short horizons; they do not build wealth over long ones.
SSY and PPF are tax-free — worth about 3 percentage points a year in the top slab.
TDS is not your final tax liability, and cumulative FD interest is generally taxable as it accrues.
Ladder maturities to blunt reinvestment risk.
