SIP vs FD vs PPF vs Gold: The Honest Post-Tax Comparison (2026 Real Data)
Rs 10K/month for 15 years: SIP gives Rs 50.5L, PPF Rs 32.6L, Gold Rs 41.5L, FD Rs 26.4L post-tax at 30% bracket. The honest 4-way comparison with real historical data.
The Internet Compares Pre-Tax Returns. You Earn Post-Tax Returns. Here’s What Rs 10,000/Month Actually Becomes in Each — With Historical Data, Not Projections.
Every comparison article shows: SIP 12%, Gold 10%, PPF 7.1%, FD 7%.
SIP wins. Case closed.
Except it’s not that simple. FD interest is taxed every year at your slab rate. SIP gains face 12.5% LTCG + 4% cess. PPF is completely tax-free. Gold SGBs are tax-free at maturity.
At the 30% tax bracket, the ranking changes. At shorter time horizons, it changes again. And when you factor in that 62% of SIP investors quit within 3 years — the theoretical returns become irrelevant.
This guide shows the actual post-tax, inflation-adjusted comparison using historical data. No projections. No cherry-picked periods. No product to sell.
The Post-Tax Corpus: Rs 10,000/Month for 15 Years
| Instrument | Gross Rate | Tax Treatment | Post-Tax Corpus (30% bracket) | Real Value (6% inflation) |
|---|---|---|---|---|
| SIP (Nifty 50) | 12% CAGR | 12.5% LTCG + 4% cess | Rs 44.2 lakh | Rs 18.4 lakh |
| Gold (SGB) | 10% + 2.5% interest | Tax-free at maturity | Rs 41.5 lakh | Rs 17.3 lakh |
| PPF | 7.1% | 100% tax-free (EEE) | Rs 32.6 lakh | Rs 13.6 lakh |
| FD (SBI) | 7.0% gross | Taxed annually at slab | Rs 26.4 lakh | Rs 11.0 lakh |
Total invested in each: Rs 18 lakh.
SIP wins nominally. But look at the risk it took to get there.
What the Numbers Hide: The Worst-Case Periods
SIP doesn’t always deliver 12%. Here’s what happened in the worst periods:
| Period | SIP XIRR | PPF Rate | FD Post-Tax (30%) | Gold Return |
|---|---|---|---|---|
| 2008–2012 (5 years) | 4.2% | 8.0% | 4.8% | 18.2% |
| 2010–2013 (3 years) | -2.1% | 8.6% | 5.1% | 7.4% |
| 2015–2018 (3 years) | 7.8% | 7.9% | 4.7% | 2.1% |
| 2018–2020 (2 years) | 1.4% | 7.9% | 4.7% | 24.3% |
Key takeaway: In 40% of all 3-year rolling periods between 2008–2013, equity SIPs delivered less than FD. The “SIP always wins” narrative requires a minimum 10-year commitment — and most investors don’t stay that long.
The PPF Tax Advantage Nobody Calculates
PPF at 7.1% looks lower than everything. But it’s the only instrument with EEE status (Exempt-Exempt-Exempt). To match PPF’s 7.1% in a taxable instrument, you need:
| Your Tax Bracket | Pre-Tax Rate Needed to Match PPF 7.1% | Closest Available Instrument |
|---|---|---|
| 0% | 7.1% | Any FD at 7%+ |
| 10% | 7.9% | Small finance bank FD |
| 20% | 8.9% | NBFC deposit (not DICGC insured) |
| 30% | 10.1% | Nothing available |
At the 30% bracket, no legitimate fixed-income instrument in India matches PPF post-tax. This is why the rule is: max PPF (Rs 2 lakh/year) before any FD if you’re in the 20%+ bracket.
The Gold Problem: 0% Real Return for 20 Years
Gold’s 2001–2024 performance (10%+ CAGR in INR) is historically anomalous. Context:
- 1980–2000: Gold in INR gave approximately 0% real return (price rise matched inflation)
- 2013–2017: Gold gave -0.4% nominal return over 4 years
- 2001–2012: Gold gave 18%+ CAGR — an outlier driven by global QE and rupee depreciation
Gold is not an inflation hedge. It’s a currency depreciation hedge. If the rupee stabilizes against the dollar, gold in INR can stagnate for a decade.
The SGB advantage: Sovereign Gold Bonds pay 2.5% annual interest on top of gold appreciation, tax-free at 8-year maturity. This makes SGBs strictly better than physical gold or Gold ETFs. However, new SGB issuances stopped in February 2024 — secondary market is the only option.
The FD Wealth Destruction Math
At the 30% bracket with 6% inflation, here’s what an FD actually does to your money:
- Gross FD rate: 7.0%
- Post-tax return: 7.0% × (1 - 0.30) = 4.9%
- Inflation: 6.0%
- Real return: -1.1%
On Rs 10 lakh in FD for 10 years at 30% bracket:
- Nominal value at maturity: Rs 16.1 lakh
- Purchasing power of Rs 16.1 lakh at 6% inflation: Rs 9.0 lakh in today’s rupees
- You invested Rs 10 lakh. You can now buy goods worth Rs 9.0 lakh. You lost Rs 1 lakh in real terms.
FD is a holding pen, not an investment, for anyone in the 20%+ bracket.
When FD Makes Sense
- Emergency fund (3-6 months expenses) — you need instant liquidity
- Goals within 2-3 years — too short for equity or PPF
- Senior citizens at 0-5% bracket — 8.5-9.5% rates at small finance banks + 80TTB deduction
- FD ladder strategy across multiple banks
The Optimal Allocation Framework
There is no single “best” option. The right answer depends on your tax bracket, time horizon, and risk tolerance.
For 25–35 Year Olds (10–25 Year Horizon, 20–30% Bracket)
| Allocation | Instrument | Why |
|---|---|---|
| 55–60% | Equity SIP (index fund) | Highest long-term post-tax return; time absorbs volatility |
| 25% | PPF (max Rs 2L/year) | Tax-free debt anchor; guaranteed; sovereign backing |
| 10–15% | Gold (SGB or Gold ETF) | Portfolio diversification; low correlation with equity |
| 0–5% | FD | Only for emergency fund; not for wealth building |
For 45–55 Year Olds (5–15 Year Horizon, 20–30% Bracket)
| Allocation | Instrument | Why |
|---|---|---|
| 30% | Equity SIP | Reduced allocation as time horizon shrinks |
| 35% | PPF (extend existing) | Tax-free compounding; partial withdrawal from Year 7 |
| 15% | Gold (SGB) | Inflation hedge for retirement years |
| 20% | FD ladder (SFBs) | Liquidity + higher rates across banks |
For Senior Citizens (0–10% Bracket)
| Allocation | Instrument | Why |
|---|---|---|
| 10–15% | Equity (SWP from existing) | Beat inflation; SWP structure |
| 30% | SCSS (Rs 12.2L max) | 8.2% quarterly payout; Rs 1L covered by 80TTB |
| 25% | PPF extension | Tax-free; unlimited withdrawals on extension without deposits |
| 20% | FD ladder (SFBs, 9%+) | Low bracket means high post-tax yield |
| 10% | Gold/SGB | Held from earlier; let it mature tax-free |
The Behavioral Reality: Why Theory Doesn’t Match Practice
62% of SIP Investors Quit Within 3 Years
AMFI data shows that most SIP investors stop during market corrections. The theoretical 12% CAGR over 15 years requires staying invested through:
- 30–40% market crashes (2008, 2020)
- 2–3 year periods of negative returns
- Monthly statements showing losses on your existing corpus
If you know you’ll panic and redeem during a crash, PPF at 7.1% guaranteed is a better real-world outcome than a theoretical 12% you never achieve.
The Rs 2 Lakh PPF Limit Problem
PPF only allows Rs 2 lakh/year (approximately Rs 16,667/month). For larger monthly investments, you have to split across instruments regardless. If you invest Rs 50,000/month:
- First Rs 16,667 → PPF (no question at 20%+ bracket)
- Next Rs 25,000–30,000 → Equity SIP
- Remaining → Gold SGB or debt funds
Gold: Cultural Allocation vs Rational Allocation
Indian families allocate 20–40% of savings to gold (physical, for weddings). From a pure investment standpoint, 10–15% is the rational maximum. If your family “needs” physical gold, separate that from your investment portfolio — don’t count wedding jewellery as portfolio allocation.
The SIP Rate Illusion: CAGR vs XIRR
A fund showing 15% CAGR does not give you 15% returns on a monthly SIP.
- Lump sum at 15% CAGR for 15 years: Rs 10L becomes Rs 81.4L
- Monthly SIP of Rs 5,556 (same total Rs 10L) at 15% CAGR: gives 12.1% XIRR = Rs 41.2L
The difference: your later installments compound for fewer years. A 15% CAGR fund gives approximately 12% XIRR on monthly SIP. This is not a bug — it’s math. Most SIP comparison articles use CAGR numbers for SIP projections, inflating expected returns.
The Rate Sensitivity Problem: PPF and FD Are Political Instruments
PPF Rate Cuts Since 2000
| Period | PPF Rate | 10Y G-Sec (supposed basis) |
|---|---|---|
| Before April 2000 | 12.0% | 11.5% |
| April 2003 | 8.0% | 6.2% |
| April 2012 | 8.8% | 8.4% |
| April 2016 | 8.1% | 7.5% |
| January 2018 | 7.6% | 7.3% |
| October 2018 | 8.0% | 7.8% |
| April 2020 | 7.1% | 6.0% |
| April 2026 | 7.1% | 6.7% |
The government is supposed to reset PPF quarterly at 10Y G-sec minus 25bps. They haven’t followed the formula — current formula yield would be ~6.45%. The 7.1% rate is politically maintained. It could drop in any quarter. Anyone projecting 7.1% for a full 15-year PPF tenure is being optimistic.
Realistic assumption: 6.5–6.7% effective average over a new PPF tenure starting 2026.
Even at 6.5%, the pre-tax equivalent at 30% bracket is 9.3% — still better than any available taxable fixed-income option.
Small Finance Bank FD Arbitrage: Does It Change the Math?
| Bank | Rate (Regular) | Rate (Senior) | DICGC Insured? | Effective Post-Tax (30%) |
|---|---|---|---|---|
| Unity SFB | 9.0% | 9.5% | Yes (Rs 5L) | 6.3% |
| Ujjivan SFB | 8.25% | 8.75% | Yes (Rs 5L) | 5.8% |
| AU SFB | 8.0% | 8.5% | Yes (Rs 5L) | 5.6% |
| Shriram Finance | 8.9% | 9.4% | No (NBFC) | 6.2% |
| SBI | 6.8% | 7.3% | Yes (Rs 5L) | 4.8% |
Even the best SFB FD at 9% gives just 6.3% post-tax at 30% bracket — still below PPF’s 7.1% tax-free.
The SFB FD strategy works for:
- Senior citizens in 0–10% bracket (effective 8.5–9.1% post-tax)
- Amounts exceeding Rs 2L/year PPF limit
- Goals under 5 years (PPF’s lock-in is too long)
- Spreading across 4–5 banks to stay within Rs 5L DICGC per bank
The Verdict: Rules That Actually Work
-
Max PPF first (Rs 2L/year) if you’re in the 20%+ bracket and have a 15-year horizon. Nothing beats tax-free EEE in fixed income.
-
Equity SIP only for 10+ year goals. Below 7 years, the probability of underperforming FD is too high to accept the volatility.
-
Gold at 10–15% of portfolio maximum. Use SGBs (secondary market) or Gold ETFs. Never physical gold as “investment.” The 2001–2024 bull run is not a permanent baseline.
-
FD is for emergency fund only at 20%+ bracket. It’s not an investment — it’s a liquidity instrument. Use it for 3–6 months expenses and nothing more.
-
The real comparison is SIP vs PPF, not SIP vs FD. FD loses to both after tax. The decision is: how much risk can you actually handle?

Frequently Asked Questions
Which gives the highest returns — SIP, FD, PPF, or Gold?
Over 15+ years, equity SIP (Nifty 50) delivers 12-13% CAGR, beating Gold (10-11% + 2.5% SGB interest), PPF (7.1% tax-free), and FD (4.9% post-tax at 30% bracket). However, SIP lost money in 40% of 3-year periods between 2008-2013. For guaranteed post-tax returns, PPF at 7.1% tax-free (effective 10.1% pre-tax equivalent at 30% bracket) is unbeatable among fixed-income options.
What is the post-tax return of SIP vs FD vs PPF vs Gold at 30% bracket?
SIP: ~11.2% effective (after 12.5% LTCG + 4% cess). FD at 7%: 4.9% post-tax (taxed annually at slab). PPF: 7.1% fully tax-free (EEE status, no tax ever). Gold SGB: full gold appreciation + 2.5% interest, completely tax-free if held to 8-year maturity. In rupee terms on Rs 10K/month for 15 years: SIP Rs 44.2L, Gold Rs 41.5L, PPF Rs 32.6L, FD Rs 26.4L after all taxes.
Is PPF really better than FD for the 30% tax bracket?
Mathematically, yes — by a wide margin. PPF 7.1% tax-free equals a pre-tax return of 10.14% at the 30% bracket. No bank FD in India offers 10.14%. Even small finance banks at 9% yield just 6.3% post-tax. PPF wins by 80 basis points over the best available FD after tax. The only reason to choose FD over PPF is if you need the money within 5 years.
Should I invest in Gold ETF or Sovereign Gold Bonds?
SGBs are strictly superior if you can hold 8 years. You get gold price appreciation plus 2.5% annual interest, with zero capital gains tax at maturity. Gold ETFs have tracking error (0.5-1.2% annually) plus expense ratio — losing 8-15% vs actual gold over 10 years. Catch: new SGB issuances stopped since February 2024. Secondary market SGBs trade at 3-8% discount but have low liquidity.
What is the ideal allocation between SIP, FD, PPF, and Gold?
For a 30-year-old at 30% bracket with 10+ year horizon: 55-60% equity SIP (index fund), 25% PPF (max Rs 2L/year), 10-15% Gold (SGB/ETF). FD only for emergency fund (3-6 months expenses). For a 50-year-old: 30% SIP, 35% PPF, 15% Gold, 20% FD ladder. Key rule: max PPF (Rs 2L/year) before any FD at 20%+ bracket. No FD matches PPF post-tax.
Can SIP lose money over 5-10 years?
Yes. Nifty 50 SIP from January 2008 to December 2012 (5 years) delivered just 4.2% XIRR — barely above a savings account. In 40% of 3-year rolling periods during 2008-2013, equity SIPs gave negative or sub-FD returns. The SIP always wins narrative holds only for 10+ year periods with diversified equity exposure. For sub-7-year goals, PPF or FD ladder is objectively safer.
How does inflation destroy FD returns at the 30% bracket?
FD at 7% gross yields 4.9% post-tax at 30% bracket. With 6% inflation, real return is -1.1%. Your Rs 10 lakh in an FD becomes Rs 10.49 lakh after one year in nominal terms — but goods that cost Rs 10 lakh now cost Rs 10.60 lakh. You lost Rs 11,000 in purchasing power. Over 15 years, your FD corpus buys 15% less than what you invested. FD at this bracket is a slow wealth destroyer.
Gold gave 0% real return for 20 years — should I still invest?
Yes, but limit to 10-15% of portfolio. Gold from 1980-2000 returned approximately 0% after inflation in INR terms. The 2001-2024 bull run (10%+ CAGR) was driven by rupee depreciation and global monetary policy — not repeatable indefinitely. Gold works as a currency hedge, not a compounder. Use it for diversification (low correlation with equity), not as a primary wealth builder.
Why do most comparison articles show SIP always winning?
Because mutual fund distributors publish them to earn commissions. They cherry-pick the 2013-2024 bull run (Nifty 14%+ CAGR) and ignore 2008-2013 (SIP barely beat FD). They compare nominal pre-tax returns — ignoring PPF's tax-free EEE status. An honest comparison must use post-tax returns, include worst-case historical periods, adjust for inflation, and acknowledge that 62% of SIP investors quit within 3 years.
PPF rate has been cut 9 times — will it keep falling?
Likely yes, gradually. PPF rate dropped from 12% (2000) to 7.1% (2020-present). It is supposed to track 10-year G-sec minus 25bps but the government overrides this. If you project 7.1% for a full 15-year tenure, you are optimistic. Realistic effective rate: 6.5-6.7% averaged over 15 years. Even at 6.5%, the tax-free EEE status gives an effective pre-tax equivalent of 9.3% at 30% bracket — still better than any taxable FD.
What about NPS instead of these four options?
NPS gives equity-like returns (9-12% historically) with extra Rs 50,000 tax deduction under 80CCD(1B). But 40% of NPS corpus must buy an annuity at retirement (taxed as income, low 5-6% payout). This annuity trap reduces effective returns significantly. For pure comparison: max PPF first (Rs 2L/year), then NPS for the extra Rs 50K deduction, then equity SIP for the remainder. NPS is a tax-saving vehicle, not a wealth builder.
