PPF vs FD vs RD: Which Should You Actually Use?
All three are 'safe' savings products, but they solve completely different problems. Here's how to tell which one fits your actual goal.
PPF, FD, and RD all get lumped together as 'safe' options, and all three do avoid market risk — but they're built for different jobs. Picking between them by comparing interest rates alone misses the point; the real differences are liquidity, tax treatment, and how the money goes in.
Fixed Deposit (FD) — a lump sum, locked for a chosen term
You deposit a lump sum once, choose a tenure (as short as 7 days or as long as 10 years), and it earns a fixed rate for that entire period. FDs are the most liquid of the three — most banks allow premature withdrawal, usually with a small interest penalty. Interest is fully taxable at your slab rate, and TDS applies above a threshold.
Recurring Deposit (RD) — for building a habit, not parking a lump sum
An RD is for someone who doesn't have a lump sum yet but can commit to depositing a fixed amount every month. It behaves mathematically similar to an FD building up over time, but it's built specifically around the discipline of regular saving rather than a one-time deposit. Like FD interest, RD interest is fully taxable.
PPF — the slowest, but the only fully tax-free one
PPF locks your money for 15 years (with partial withdrawal allowed from year 7), caps contributions at ₹1,50,000/year, and in exchange gives you something FD and RD don't: EEE status — the contribution, the interest, and the maturity amount are all completely tax-free. For a long-term, low-risk goal like retirement, that tax-free compounding meaningfully beats a similar FD rate once you account for tax.
So which one?
Need the money to possibly stay liquid, or the tenure is under 5 years: FD. Building the habit of saving a fixed amount monthly toward a medium-term goal: RD. A genuinely long-term, tax-advantaged goal you won't need to touch for 15 years: PPF — often as part of a mix, not a single choice.
