Why Most Investors Quit SIPs at the Wrong Time

The market crashes. Your portfolio turns red. And your finger hovers over “Stop SIP.” Here’s why that’s the most expensive mistake you’ll ever make.

📅 February 2025 ⏱ 7 min read 🇮🇳 For Indian Investors
Let’s be real. Nobody stops their SIP when the market is up 30%. They stop it when it’s down 20% — right before it bounces back. This pattern has repeated itself in Indian markets for decades, and it keeps costing retail investors crores of rupees in missed compounding.

India had over 10 crore active SIP accounts as of late 2024, according to AMFI data. That’s a massive number. But here’s the uncomfortable truth — a significant chunk of these investors will stop, pause, or reduce their SIPs the moment markets get uncomfortable.

And they’ll do it at exactly the wrong moment. Not out of stupidity, but out of very human emotion. That’s what we need to talk about today.

The Market Falls. Panic Rises. SIPs Stop.

It happens like clockwork. The Sensex drops 3,000 points in a week. WhatsApp forwards start flying about “market crash 2008 repeat.” Financial news channels go wall-to-wall with bearish commentary. And the average investor — who was perfectly calm when things were good — hits pause on their SIP.

This is called panic-driven decision making, and behavioural economists have studied it for decades. Nobel laureate Daniel Kahneman’s research shows that humans feel losses roughly twice as intensely as equivalent gains. So a ₹10,000 loss in your portfolio feels as bad as a ₹20,000 gain feels good.

This psychological asymmetry is the root cause of why most SIP investors quit at the worst time.

What Actually Happens When You Stop a SIP Mid-Way

Let’s look at real numbers, not hypotheticals.

📊 A Simple ₹10,000/month SIP Scenario

Investor A runs a SIP of ₹10,000/month for 20 years at an assumed 12% CAGR (historically reasonable for large-cap equity mutual funds in India). His corpus at the end: approximately ₹98 lakhs.

Investor B does the same but stops for 2 years during the 2020 COVID crash and the 2022 correction — two of the best buying opportunities in recent history. His final corpus: approximately ₹71 lakhs.

That gap? ₹27 lakhs. Just from two years of stopping. That’s the real cost of quitting at the wrong time.

Note: Figures are illustrative based on standard SIP calculators using 12% CAGR. Actual returns vary. Past performance is not a guarantee of future results.

The cruelest part? The months when most SIPs get stopped — during sharp market corrections — are precisely the months when your ₹10,000 buys the most units. When NAV is low, you accumulate more. Stop then, and you miss the recovery entirely.

The 3 Moments Investors Almost Always Get Wrong

1. When Markets Drop 15–20% in a Short Period

This feels catastrophic. Your portfolio dashboard turns blood red. But historically, the Indian stock market (Nifty 50) has always recovered from every single correction. The 2008 crash (down ~60%), the 2020 COVID crash (down ~38%), the 2022 rate hike correction — all fully recovered and went on to make new highs.

Stopping your SIP here is like leaving a sale at half price because the price dropped too fast.

2. When Personal Financial Pressure Hits

Job insecurity, medical expenses, EMI stress — these are valid reasons to revisit your financial plan. But stopping a SIP should be the last option, not the first. Reducing it to a smaller amount is almost always a better call than stopping entirely.

⚠️ Important: If you’re facing genuine financial hardship, it’s completely fine to reduce your SIP amount temporarily. But try to keep it running, even at ₹500/month. The habit matters as much as the amount.

3. When “Better Opportunities” Appear

Real estate is booming. Your cousin made 40% on a stock tip. Crypto is suddenly everywhere. These distractions have historically cost Indian retail investors far more than market crashes. SIPs work because of discipline, not timing. The moment you start chasing “better” opportunities, you start losing the one edge SIPs give you — consistency.

Why Rupee Cost Averaging Is Your Biggest Unfair Advantage

SIPs work on a principle called Rupee Cost Averaging (RCA). When markets fall, your fixed monthly investment buys more mutual fund units. When markets rise, it buys fewer. Over time, this averages out your cost per unit and significantly reduces the impact of market volatility.

The only way this works in your favour is if you stay invested through the dips. The moment you stop, you freeze your average cost at exactly the point when it should be coming down.

✅ The math is simple: If your mutual fund NAV falls from ₹100 to ₹75, your ₹10,000 SIP now buys 133 units instead of 100. When the NAV recovers to ₹100, those extra 33 units are pure profit you’d have missed by stopping.

The Psychology Trap: Why Your Brain Is Working Against You

Your brain isn’t wired for long-term investing. It’s wired for short-term survival. A stock portfolio declining triggers the same threat-response system that your ancestors used to avoid predators. It’s not rational, but it’s deeply biological.

This is why systematic investing — removing human decision-making from the equation — is so powerful. Once a SIP is set up, it runs automatically. The biggest enemy isn’t the market. It’s the moment you choose to intervene.

Research from Franklin Templeton India found that investors who stayed invested through the entire 2020 COVID crash cycle recovered fully within 12–18 months. Those who stopped and re-entered later typically missed 15–25% of the recovery.

When Is It Actually Okay to Stop a SIP?

To be fair — there are legitimate reasons to stop or restructure your SIP. Let’s not pretend otherwise.

  • Your financial goal has been achieved and you need the money now
  • The fund has consistently underperformed its benchmark for 3+ years (time to switch, not stop)
  • You’ve lost your primary income source and genuinely cannot afford any investment
  • You’re consolidating multiple SIPs into a better-performing fund
  • Your risk profile has genuinely changed (e.g., you’re retiring soon)

Notice what’s not on that list? “The market crashed.” “My portfolio is in the red.” “My friend told me to stop.” Those are emotional triggers, not logical ones.

What Smart SIP Investors Do Differently

The investors who build real wealth through SIPs don’t do anything complicated. They do the boring, unsexy thing: they keep going. But there are a few smart habits that set them apart.

They increase their SIP amount during market downturns instead of stopping. They review performance annually, not monthly. They ignore short-term NAV movements and focus on their goal completion date. And they set up SIP payments right after salary credit — so the money is invested before they can think about spending it.

They also understand one simple truth: time in the market always beats timing the market. This has been proven in virtually every market study done on Indian mutual funds over the last 20 years.

The Final Word: Stay the Course

India’s mutual fund industry has grown from ₹7 lakh crore AUM in 2016 to over ₹60 lakh crore in 2024. That growth happened because millions of ordinary investors trusted the process, stayed invested through multiple market cycles, and let compounding do its job.

The investors who built wealth weren’t smarter. They weren’t richer. They were just more patient. They stopped checking their portfolios every day. They stopped listening to noise. And they kept their SIPs running through every crash, every correction, and every bearish headline.

If you’re reading this during a market downturn — good. That means this is exactly when you need to hear it. Don’t stop your SIP. Don’t pause it. If anything, increase it.

The market will recover. It always has. The question is whether you’ll be in it when it does.
