Both PPF and fixed deposits get recommended as "safe" places to put money, which makes them sound interchangeable — they're not. Once you look past the safety label, they behave very differently on returns, taxes, and how easily you can get your money back.
The headline numbers
PPF currently pays 7.1% per annum, a rate set by the government and reviewed quarterly — it's stayed at 7.1% since April 2020. Bank fixed deposits vary by bank and tenure, commonly landing somewhere in the 6-7.5% range, sometimes higher for specific tenures or senior citizen rates. On raw interest rate alone, they're often close enough that rate isn't really the deciding factor — the real differences are elsewhere.
Taxation is where they diverge sharply
This is the biggest practical difference. PPF has what's called EEE status — Exempt, Exempt, Exempt. Your contribution is deductible under Section 80C (up to ₹1.5 lakh), the interest earned is completely tax-free, and the maturity amount is tax-free too. Nothing about a PPF account gets taxed at any stage.
A fixed deposit's interest, by contrast, is fully taxable as income at your slab rate — there's no exemption on FD interest itself (a 5-year tax-saving FD only gives you the 80C deduction on the deposit, not on the interest earned). If you're in a high tax bracket, this difference alone can make PPF's real, after-tax return meaningfully better than an FD's headline rate suggests.
Access to your money
This is where FDs clearly win. A fixed deposit can typically be broken early (usually with a small penalty on the interest rate) if you need the money urgently. PPF has a mandatory 15-year lock-in, with only limited partial withdrawals allowed starting from the 7th year, under specific conditions. If there's a real chance you'll need this money within a few years, PPF's illiquidity is a serious constraint, not a minor inconvenience.
Contribution limits
PPF caps annual contributions at ₹1.5 lakh per person per year — you simply can't put more into it even if you want to. FDs have no such ceiling; you can deposit as much as you have. For larger savings amounts beyond the PPF limit, an FD (or other instruments) becomes necessary regardless of which one you'd otherwise prefer.
A simple way to think about it
- Money you won't need for 15+ years, and want guaranteed, tax-free growth — PPF's tax treatment makes it hard to beat for this specific purpose, especially combined with the 80C deduction.
- Money you might need access to sooner, or an amount beyond the PPF ceiling — FD is the more flexible, practical choice, even with the interest being taxable.
- Most people end up using both — PPF for a portion of long-term, untouchable retirement savings, and FDs for shorter-term goals or amounts that don't fit PPF's constraints.
