You've seen the ad a hundred times. Hopeful young couple. Coffee in hand. A SIP calculator glowing on the laptop. ₹5,000 × 30 years × 12% = ₹1.76 crore. Background music swells. The voiceover says: "Sahi mutual fund chuno, aur crorepati ban jao."
Beautiful. Inspiring. And mostly a lie.
Look, I'm not anti-SIP. Far from it. AMFI's latest data shows monthly SIP inflows crossed ₹32,000 crore in March 2026 — a record. Retail Indians have finally stopped chasing FDs and chit funds. That's a win.
But the calculator? The calculator is a sales tool. It shows you the gross number — before four silent killers eat into it.
The Number They Show You vs. The Number You Get
1. Expense Ratio — The 30-Year Tax You Never See
Every mutual fund charges 0.5% to 2.25% per year just to manage your money. Regular plans charge more, direct plans charge less. Over 30 years, a 1.5% expense ratio shaves roughly ₹25 lakh off your final corpus.
Your ₹1.76 crore is now ₹1.50 crore. We're just getting started.
2. LTCG Tax — The Final Slap
From April 2024, long-term capital gains on equity mutual funds are taxed at 12.5% above ₹1.25 lakh per year. When you finally redeem your corpus, the taxman is waiting at the door.
On a ₹1.5 crore corpus with ₹18 lakh invested capital, your gains of ~₹1.32 crore attract roughly ₹16 lakh in tax. Now you're holding ₹1.34 crore.
3. Inflation — The Killer Nobody Talks About
This is the brutal one. Sit with it for a second.
India's long-term retail inflation averages around 6%. At that rate, ₹1 today is worth about ₹0.17 in 30 years. Meaning your ₹1.34 crore corpus in 2055 has the actual purchasing power of roughly ₹23 lakh in today's money.
Read that again. Thirty years. Eighteen lakhs of your own money invested. Final purchasing power: enough for a decent sedan, not a crorepati lifestyle.
4. The Behaviour Gap — You Are Your Own Enemy
Morningstar's Mind the Gap studies have shown for years that retail investors underperform their own funds by 1–3% annually. Why? Because they pause SIPs when markets crash (the worst time to stop), chase last year's winners, and redeem early to fund a wedding or car.
SEBI data after every major correction confirms the same pattern in India. Lakhs of SIPs go silent. Each pause costs lakhs in the long run.

Want a real ₹1 crore (today's value) at retirement? You'd need a maturity corpus of roughly ₹5.7 crore — which means a SIP of around ₹15,000 to ₹18,000 per month, not ₹5,000. That's the honest math.
So Should You Stop SIPs? Hell No.
The alternative is worse. A savings account gives 3%. An FD gives 6–7%. Both lose to inflation after tax. SIPs in equity mutual funds still beat almost every accessible asset class for long-term wealth-building in India.
The point isn't to quit. The point is to stop fooling yourself.
Here's what actually works:
- Step up your SIP 10% every year. Most AMCs let you do this automatically. It nearly doubles your final corpus over 30 years.
- Switch to direct plans. That single move saves 0.7–1% per year. Huge over decades.
- Don't pause during crashes. Repeat after me: crashes are discounts.
- Recalculate your goals in real terms, not nominal. A ₹2 crore retirement target in 2055 is roughly today's ₹33 lakh. Plan accordingly.
- If you're under the old tax regime, route part of your SIP through ELSS — same growth, plus 80C deduction.
The Bottom Line
The SIP calculator was built to sell you a product, not to plan your retirement. Take the number it gives you, then mentally cut it by 80% to get the real, inflation-adjusted figure.
Your ₹5,000 SIP isn't useless. It's just nowhere near enough.
Run the honest math. Step up every year. Stay invested through pain. Phir crorepati banoge — calculator se nahi, discipline se.
