PPF vs Fixed Deposit: The Short Answer
In the PPF vs fixed deposit choice, PPF wins for anyone in the 20% or 30% slab with a 15-year horizon. PPF's 7.1% (October–December 2026 quarter) is tax-free, which at the 30% slab equals an FD paying about 10.14% before tax, while a 7% FD leaves you 4.9% after tax. FDs still make sense if you need the money within 3 years or pay little or no tax.
Both are safe and widely available. The gap comes almost entirely from how the interest is taxed.
How PPF Works
The Public Provident Fund is a government scheme with a 15-year lock-in, currently paying 7.1% per annum (compounded annually). You can invest ₹500 to ₹1.5 lakh per year. The account can be extended in 5-year blocks after maturity.
Tax status: EEE (Exempt-Exempt-Exempt). Contributions are deductible under Section 123 of the Income-tax Act 2025 (formerly 80C; old regime only), interest is tax-free, and maturity amount is tax-free. It is one of the very few investments in India with complete tax exemption at all three stages.
How Fixed Deposits Work
Bank FDs are simple: deposit a lumpsum or regular amounts for a fixed tenure at a fixed interest rate. Current rates range from 6.5–8% depending on tenure and bank type (small finance banks offer up to 9%). However, FD interest is fully taxable: it is added to your income and taxed at your slab rate.
The After-Tax Return Comparison
| Investment | Rate | Tax on Interest | After-Tax Return (30% bracket) | After-Tax Return (20% bracket) |
|---|---|---|---|---|
| PPF | 7.1% | Zero (EEE) | 7.1% | 7.1% |
| Bank FD (SBI, 3-year) | 6.30% | 30% / 20% | 4.41% | 5.04% |
| Small Finance Bank FD | 8.5% | 30% / 20% | 5.95% | 6.8% |
| Post Office TD (5-year) | 7.5% | Sec 123 (old 80C) deduction on deposit, old regime | ~5.25% | 6.0% |
Rates as of October 2026: PPF and Post Office TD from the Ministry of Finance notification for October–December 2026; SBI 3-year FD rate effective 15 December 2025. Small finance bank rates vary by bank.
For anyone in the 30% tax bracket, PPF at 7.1% is essentially equivalent to an FD paying 10.14% on a pre-tax basis. No FD in the market comes close to this effective return.
PPF Wins on Returns But Loses on Liquidity
The 15-year lock-in is PPF's biggest drawback. However, there is more flexibility than most people realise:
- Loan against PPF: From Year 3 to Year 6, you can take a loan up to 25% of the balance at Year 2
- Partial withdrawal: From Year 7 onward, you can withdraw up to 50% of the balance at the end of Year 4 (or the previous year, whichever is lower)
- Premature closure: Allowed after 5 years for specific reasons (medical treatment, higher education)
When to Choose FD Instead
- You need the money in less than 3 years, since PPF doesn't suit short-term goals
- You are already maximising ₹1.5 lakh under Section 123 (formerly 80C) through other investments and EPF, or you use the new regime
- You are in the 0% or 5% tax bracket, so tax on FD interest is minimal
- You are a senior citizen (60+) getting an additional 0.25–0.5% on FDs and reduced tax liability
A Worked Example: ₹1.5 Lakh/Year Over 15 Years
Assume you invest ₹1.5 lakh every year for 15 years (the full Section 123, formerly 80C, limit) and compare PPF against a 5-year tax-saver FD that is rolled over, and a regular 7% non-tax-saver FD.
| Instrument | Gross Return | Post-Tax Return (30% bracket) | Corpus at Year 15 |
|---|---|---|---|
| PPF (7.1% EEE) | 7.1% | 7.1% | ₹40.68 lakh |
| Tax-saver FD @ 7% | 7.0% | 4.9% | ₹33.70 lakh |
| Small Finance Bank FD @ 8.5% | 8.5% | 5.95% | ₹36.85 lakh |
The PPF investor ends up about ₹3.8–7 lakh richer, purely because PPF interest is never taxed. And the ₹40.68 lakh is completely tax-free when withdrawn; the FD corpus has already had tax deducted each year at your slab rate.
The Senior Citizen Exception
Rules change materially after age 60. Senior Citizens Savings Scheme (SCSS) pays 8.2% (October–December 2026 quarter), and senior citizen FDs typically add 0.25–0.50% to standard rates. More importantly, under the old tax regime seniors can deduct up to ₹50,000 of interest income per year (the deduction formerly under Section 80TTB). So on the first ~₹6–7 lakh of FD principal, seniors effectively pay no tax on interest.
For someone above 60 with a shorter horizon (5–10 years), a mix of SCSS + senior citizen FDs often beats PPF on both liquidity and net return. PPF still wins for very long horizons, but the gap narrows dramatically.
The 5 Most Common Mistakes People Make
- Treating PPF as a primary emergency fund. The 15-year lock-in and strict partial-withdrawal rules mean PPF is the worst place for money you might need suddenly. Keep emergency money in a liquid fund or sweep-in FD.
- Depositing on the 5th of the month or later. PPF interest is calculated on the lowest balance between the 5th and the end of the month. Always deposit before the 5th of every month.
- Stopping contributions during salary dips. Missing even ₹500 in a year inactivates the account. Reactivation costs ₹50 per year plus the minimum ₹500 for each missed year.
- Splitting FDs inefficiently for TDS avoidance. TDS on FD interest kicks in above ₹50,000 (₹1,00,000 for seniors) per bank per year (Section 393(1), Income-tax Act 2025). Fragmenting FDs across banks to dodge TDS doesn't save tax. It only delays TDS; you still owe the full tax at filing time.
- Not extending PPF at maturity. After 15 years, PPF can be extended in 5-year blocks with or without contributions, and the corpus continues to earn tax-free interest. Closing the account at Year 15 is almost always a mistake unless you have a better tax-free alternative. If you do take the money out, here is what to do when your PPF matures.
Frequently Asked Questions
Is PPF really completely tax-free?
Yes. Under EEE status, there is no tax at the time of investment (Section 123 deduction up to ₹1.5 lakh under the old regime), no tax on annual interest credited, and no tax on maturity proceeds. PPF, EPF, and tax-free bonds (now mostly stopped being issued) are the only major EEE instruments available to Indian retail investors.
Can I have more than one PPF account?
No. An individual can hold only one PPF account in their own name. You can, however, also open one for each minor child you are the guardian of, but the combined contribution across your account and the children's accounts cannot exceed ₹1.5 lakh per year for the Section 123 deduction. For a daughter under 10, Sukanya Samriddhi Yojana pays 8.2% (October–December 2026), is also tax-free, and counts towards the same deduction; our SSY vs mutual funds comparison runs the numbers.
What happens if I deposit more than ₹1.5 lakh in a year?
The excess does not earn interest and is not eligible for the Section 123 (formerly 80C) deduction. Some banks auto-refund the excess; others may hold it interest-free until the next financial year. Always cap annual contributions at ₹1.5 lakh.
Are FDs safe? What about bank failures?
FDs are insured only up to ₹5 lakh per depositor per bank under DICGC. That includes savings + FD balances combined. For larger sums, split across multiple banks (preferably scheduled commercial banks over smaller co-operative banks).
What is the difference between a regular FD and a tax-saver FD?
A tax-saver FD has a mandatory 5-year lock-in and qualifies for the Section 123 (formerly 80C) deduction on the principal under the old regime. A regular FD has no lock-in (premature withdrawal with penalty) and offers no tax deduction. Interest on both is fully taxable at your slab rate.
Can I transfer my PPF account from one bank to another?
Yes. PPF accounts are portable between banks and post offices. Submit Form H at the transferring branch. Interest accrual is not interrupted during transfer.
The Verdict: PPF or FD?
For anyone in the 20% or 30% tax bracket with a 15-year horizon, PPF beats FDs in almost every scenario. At the 30% slab its tax-free 7.1% is worth more than 10% from a taxable FD, which is more than even 9% small finance bank FDs pay. The 15-year lock-in is the price of that return, and it also forces the discipline that quietly builds a retirement corpus.
