Three names dominate every Indian savings conversation: the bank FD everyone understands, the PPF every uncle recommends, and Sukanya Samriddhi for daughters. They serve different purposes - here is the honest comparison, with the math to back it.
The three schemes in one look
A Fixed Deposit is a bank product: you park a lump sum for a chosen period at a fixed rate, and the interest is fully taxable as income. PPF (Public Provident Fund) is a 15-year government scheme: up to ₹1.5 lakh per year, currently around 7.1% interest, and completely tax-free - the deposit qualifies for 80C, the interest is tax-free, and the maturity is tax-free (the famous EEE status). Sukanya Samriddhi Yojana (SSY) is for a daughter under 10: deposits for 15 years, maturity 21 years after opening, at the highest rate of any government scheme - around 8.2% - also fully tax-free.
The pattern: FD wins on flexibility, PPF on tax-free long-term compounding, SSY on rate - if you have a daughter and the patience for its timeline.
The tax difference is bigger than the rate difference
An FD at 7% sounds close to PPF at 7.1% - until tax. FD interest is added to your income: in the 30% bracket, that 7% becomes roughly 4.9% in hand. PPF’s 7.1% stays 7.1%. Over 15 years of compounding, this gap is enormous.
Run the numbers yourself: the PPF Calculator shows that ₹1.5 lakh a year for 15 years at 7.1% grows to roughly ₹40.7 lakh - of which about ₹18 lakh is pure tax-free interest. The FD Calculator with the same deposits shows a visibly smaller post-tax outcome for most tax brackets.
Sukanya Samriddhi: the daughter advantage
SSY’s rate premium plus its long runway produce startling numbers: ₹1.5 lakh a year for the 15 deposit years, then six more years of untouched compounding until maturity at 21, lands around ₹70 lakh at current rates - try it on the Sukanya Samriddhi Calculator. That is education-abroad money, built from disciplined yearly deposits.
The constraints are real, though: only for a girl child below 10 at account opening, money is essentially locked until she is 18 (partial) or maturity (full), and rates reset quarterly, so treat every projection as an estimate, not a promise.
Where FDs still win
FDs are unbeatable for money you might need: an emergency fund, a wedding two years away, a house down payment. They break easily (with a small penalty), come in any tenure from 7 days to 10 years, and are simple to ladder. Senior citizens get preferential rates, and the new tax regime’s zero-tax zone up to ₹12 lakh income means many retirees now keep more FD interest than before.
The mistake is not owning FDs - it is keeping 15-year money in them, paying tax on interest every single year while PPF investors compound tax-free.
A sensible split for a typical family
A common-sense structure: three to six months of expenses in an FD or sweep account (emergencies), ₹1.5 lakh a year into PPF (the tax-free long-term core), SSY for a daughter as far as the budget allows, and only then market instruments for growth beyond guarantees. Compare scenarios with the SIP Calculator alongside the PPF numbers to see the guaranteed-versus-market trade-off clearly.
Standard disclaimer, sincerely meant: rates change quarterly, rules change with Budgets, and this article is general information - not investment advice. Verify current rates on official channels before committing money.
Frequently asked questions
Can I have both PPF and SSY? Yes - PPF in your name and SSY in your daughter’s name are separate accounts with separate ₹1.5 lakh limits (though 80C benefit is capped overall in the old regime).
What if I miss a year in PPF? The account can be revived with a small penalty; the discipline of a yearly standing instruction avoids this entirely.
Is a post-office FD different from a bank FD? The structure is similar; post-office term deposits are government-backed and sometimes edge out bank rates - compare before locking.
EMI eating my savings? Check the true cost of any loan with the EMI Schedule tool - seeing the total interest often changes the FD-versus-prepayment decision instantly.
The discipline factor nobody discusses
On paper, comparing rates decides everything; in real life, behavior decides more. FDs are easy to break - and therefore get broken, for weddings, phones and "temporary" needs that recur yearly. PPF’s 15-year lock, cursed in year one, is precisely why PPF investors actually arrive at ₹40 lakh while FD ladders quietly leak.
SSY adds an emotional lock stronger than any rule: parents simply do not raid a daughter’s account. If you know your own discipline is the weak link, the "inflexibility" of government schemes is a feature you are buying, not a cost.
Getting started this week
PPF: any major bank or post office opens one with basic KYC; set a yearly or monthly auto-transfer and forget it - deposits before the 5th of the month earn that month’s interest. SSY: birth certificate plus parent KYC at a bank or post office; the Sukanya calculator makes a compelling exhibit for the family discussion. FDs: compare cumulative versus payout options, and ladder maturities so some money is always months away, not years.
Whatever you choose, write the maturity dates somewhere permanent, and revisit yearly with the calculators - rates move quarterly, and a ten-minute annual review keeps the plan honest.
