Three names dominate every Indian middle-class investment conversation: SIP, PPF, and FD.
Your father swears by FD. Your CA pushes PPF. Your colleague keeps showing you SIP screenshots on Instagram. Each is half right.
This guide settles it. We compare SIP vs PPF vs FD over 15 years — with real numbers, post-tax returns, risk profiles, and the right mix for the Indian middle class in 2026.
Quick Verdict — ₹10,000/Month for 15 Years
| Instrument | Assumed Return | Final Corpus | Tax on Returns | Liquidity |
|---|---|---|---|---|
| SIP (equity) | 12% | ₹50.46 L | 12.5% LTCG above ₹1.25 L/yr | Anytime |
| PPF | 7.1% | ₹32.53 L | Fully tax-free | Limited (lock-in 15 yr) |
| FD (post-tax) | 7% gross → ~5% post-tax* | ₹26.92 L | Slab rate on interest | Easy with penalty |
*FD calculation assumes 30% slab. PPF is tax-free both at investment (80C, old regime) and on returns. SIP is taxed only on redemption.
What Each Instrument Actually Is
SIP (Systematic Investment Plan)
You invest a fixed amount in equity mutual funds every month. Returns are market-linked and historically average 11–13% over 15+ years in Indian equity. No guaranteed return, but historically the highest among the three.
PPF (Public Provident Fund)
A government-backed savings scheme. Current rate is 7.1% (reviewed quarterly). 15-year lock-in. Fully tax-free (EEE — exempt at investment, growth, and withdrawal). Maximum ₹1.5 L per year.
FD (Fixed Deposit)
You park money with a bank for a fixed period at a guaranteed interest rate (currently 6.5–7.5%). Interest is fully taxable at your slab rate, which destroys real returns for anyone in the 20%+ slab.
Detailed 15-Year Comparison
Returns Side-by-Side
| Year | SIP @ 12% | PPF @ 7.1% | FD @ 7% gross |
|---|---|---|---|
| 5 | ₹8.25 L | ₹7.18 L | ₹7.19 L |
| 10 | ₹23.23 L | ₹17.27 L | ₹17.41 L |
| 15 | ₹50.46 L | ₹32.53 L | ₹31.69 L (gross) |
Risk Side-by-Side
| Risk | SIP | PPF | FD |
|---|---|---|---|
| Capital loss | Possible short-term, rare 10+ years | Zero | Zero (up to ₹5L DICGC) |
| Inflation risk | Low (returns beat inflation) | Moderate | High (real return often negative) |
| Liquidity risk | None | Very high (15-year lock-in) | Low (with penalty) |
| Reinvestment risk | None | None | Yes — rates change |
The Real Catch: Inflation
India's long-term inflation averages 5–6%. Real return = Nominal return − Inflation.
- SIP real return: 12% − 6% = 6% (your money actually grows)
- PPF real return: 7.1% − 6% = 1.1% (just beats inflation)
- FD real return (30% slab): 4.9% − 6% = −1.1% (you lose purchasing power)
This is the single most important number most Indians miss. An FD that "feels safe" is actually shrinking your money in real terms for anyone in the 20% or 30% tax slab.
Calculation Method
SIP (Future Value of a Series)
FV = P × [((1 + i)ⁿ − 1) / i] × (1 + i) At ₹10,000 × 180 months × 12% = ₹50.46 L
PPF (Annual Compounding on Yearly Deposits)
The corpus is calculated as annual deposits compounded at the prevailing rate (7.1%). With ₹1.2 L/year for 15 years, the corpus settles around ₹32.53 L — including all interest credited.
FD (Reinvestment Compounding, Post-Tax)
A recurring deposit-style equivalent of ₹10k/month for 15 years at 7% gross is ₹31.69 L before tax. Subtract tax on accrued interest at slab and the post-tax corpus for a 30% slab investor is roughly ₹26.92 L.
SIP vs PPF vs FD — Best Use Case for Each
Pick SIP when:
- Your horizon is 5+ years
- You can stomach short-term ups and downs
- You want to beat inflation comfortably
- You're building a long-term goal (retirement, child education, house in 10+ years)
Pick PPF when:
- You want zero risk + tax-free returns
- You're in the old tax regime and want full ₹1.5 L 80C deduction
- You're building a safe debt allocation alongside equity
- You don't need the money for 15 years
Pick FD when:
- Your horizon is under 3 years
- You're in a low tax slab (5% or 0%)
- You need guaranteed liquidity for emergency or short-term goals
- Senior citizens — the special senior FD rates (~7.5–8%) plus ₹50,000 interest exemption make it attractive
The Right Mix for Indian Middle Class
Don't pick one — use all three smartly.
Suggested ₹15,000/month split (₹10–25 L salary, age 25–40)
| Allocation | Amount | Purpose |
|---|---|---|
| SIP in equity mutual funds | ₹10,000 | Long-term wealth creation |
| PPF (or EPF top-up) | ₹3,000 (~₹36k/year, room till ₹1.5 L) | Tax-free safety net |
| FD / Liquid Fund | ₹2,000 | Emergency fund + short-term goals |
This builds a ₹50 L equity corpus + ₹12 L PPF + ₹6 L liquid over 15 years — diversified across growth and safety.
Common Mistakes Indians Make
- All money in FDs because "FD is safe". Safe nominally, unsafe against inflation. Real wealth erodes.
- Treating PPF as a wealth-building product. It's a safety net. 7.1% won't make you rich; it will keep you protected.
- Skipping SIP because "market is risky". Over 15+ years, SIPs in diversified equity funds have never lost money in India.
- Choosing only one of the three. Each plays a different role — equity for growth, PPF for safety, FD for liquidity. Use all.
- Ignoring taxation. FD interest is taxed at slab rate. SIP only on redemption. PPF is fully tax-free. Always compare post-tax.
- Stopping SIP during market crashes. Investors who stopped in 2008 and 2020 missed the biggest recovery gains.
- Forgetting to renew FDs. Auto-rollover at lower interest rates silently eats your returns.

FAQs
Is SIP better than PPF for 15 years?
For wealth creation, yes — ₹10,000/month SIP at 12% builds ₹50 L vs ₹32 L in PPF over 15 years. But PPF wins on safety and is fully tax-free. Most Indians should use both, not pick one.
Is FD safer than SIP?
FD is safer in the short term — capital is guaranteed. But for horizons of 7+ years, SIPs in diversified equity funds have historically never lost money in India and deliver much higher returns. Real risk for long horizons is not investing in equity.
Can I withdraw PPF before 15 years?
Partial withdrawal is allowed from the 7th year onwards, with limits. Premature closure is permitted only under specific conditions (medical emergency, higher education, NRI status) with a 1% interest penalty.
Is PPF interest taxable?
No. PPF is EEE (exempt-exempt-exempt) — the investment qualifies for 80C deduction (old regime), the interest is fully tax-free, and the maturity amount is tax-free.
How much tax do I pay on SIP returns?
Equity SIP gains held over 12 months are taxed at 12.5% LTCG above ₹1.25 L per year (FY 2025-26). Short-term gains (under 12 months) are taxed at 20%. Smart redemption across financial years can keep your tax bill near zero.
Which gives the highest return — SIP, PPF, or FD?
Over 15 years, SIP in equity mutual funds historically gives the highest return (~12% CAGR). PPF returns 7.1% currently. FD returns 6.5–7.5% gross (much lower post-tax for higher slabs).
Should I close my FD and start a SIP?
For money you won't need for 5+ years, yes — moving from FD to SIP can significantly improve real returns. But keep 3–6 months of expenses in an FD or liquid fund as emergency cover before moving everything.
How much PPF + SIP do I need for ₹1 crore in 15 years?
At 12% SIP return and 7.1% PPF rate, a mix of ₹15,000/month SIP + ₹12,500/month PPF (full ₹1.5 L/year) builds roughly ₹1.16 Cr in 15 years — well-balanced between growth and safety.
