SIP vs FD vs PPF: where should your next rupee actually go?
Every rupee you don't spend has to go somewhere, and for most people in India that "somewhere" is one of three places: a SIP into an equity mutual fund, a bank Fixed Deposit, or the Public Provident Fund. All three get recommended constantly, usually without much explanation of when each one actually makes sense.
What each one is actually optimizing for
SIP (equity mutual funds) optimizes for long-term growth, at the cost of short-term certainty. Historically, diversified equity funds in India have compounded around 11–13% annually over 10+ year periods — but that number hides years of -20% and years of +40%. If you need the money within 3–5 years, that volatility is a real risk, not a footnote.
Fixed Deposits optimize for certainty. You know exactly what you'll have on the maturity date, to the rupee. The cost is that FD returns (currently around 6.5–7.5% for most banks) barely beat inflation after tax, especially if you're in the 30% bracket — the real, inflation-adjusted return can be close to zero.
PPF sits in between: it's government-backed (so effectively risk-free like an FD) but pays a better rate (7.1% as of this writing, revised quarterly) and is fully tax-free on both the interest and maturity amount under the current EEE regime. The catch is a 15-year lock-in with limited early-exit options.
The comparison that actually matters: time horizon
| Horizon | Best fit | Why |
|---|---|---|
| < 3 years | FD / RD | Equity volatility isn't worth the risk over a short window — you might need to withdraw at a low point. |
| 3–7 years | Mostly SIP, some FD as ballast | Enough time to ride out a downturn, but you still want some certainty for the portion you can't afford to lose. |
| 7+ years / retirement | SIP-heavy, PPF as the "safe" sleeve | Long enough that equity volatility statistically smooths out, while PPF's tax-free compounding is hard to beat for the safe portion. |
Run your own numbers
Generic advice like the above is a starting point, not a plan — the right split depends on your actual income, expenses, existing savings, and how many years you have. Our Compare Lab lets you put SIP, FD, and PPF side by side with your real numbers and the same time horizon, so you can see the actual rupee difference instead of guessing from a rule of thumb.
