PPF, NSC, KVP, and Fixed Deposits are all fixed-return, government-backed or bank-backed savings instruments — but they differ enough in lock-in, tax treatment, and typical returns that picking the wrong one for your goal can cost you flexibility or money.
Quick comparison
| Instrument | Lock-in | Tax treatment | Backed by |
|---|---|---|---|
| PPF | 15 years (partial withdrawal allowed after year 6) | Exempt-Exempt-Exempt — contribution, interest, and maturity all tax-free | Government of India |
| NSC | 5 years, no premature withdrawal (except on death) | Contribution qualifies for 80C; interest is taxable but reinvested interest also qualifies for 80C | India Post |
| KVP | ~115 months (varies by notified rate), no 80C benefit | Interest is fully taxable; no deduction on investment | India Post |
| Bank/Post Office FD | Flexible — 7 days to 10 years, premature withdrawal usually allowed with a penalty | Interest is fully taxable; only 5-year tax-saver FDs qualify for 80C | Bank or India Post |
How the returns compare
At typical recent rates, ₹1,00,000 invested grows roughly like this: NSC at 7.7% over 5 years reaches about ₹1,44,900; a 5-year FD at 7% reaches about ₹1,41,500; KVP at 7.5% takes about 9.6 years (its notified doubling period) to reach ₹2,00,000. These figures shift whenever the government revises rates, which happens quarterly for PPF/NSC/KVP — always check the current rate before committing.
Which one fits which goal
- Long-term, tax-free goal (retirement, child's future) — PPF is usually the strongest choice: the full tax exemption on interest is hard to beat over a 15-year horizon.
- 5-year goal, want an 80C deduction — NSC gives you the deduction and a fixed 5-year return with no market risk.
- Simple doubling, no tax planning needed — KVP is straightforward but offers no tax deduction, so it's less efficient than NSC for the same money if you still have 80C room left.
- Need flexibility or a shorter horizon — FDs are the most liquid of the four, with tenures as short as a few days and generally easier premature exit.
