Key Takeaways
- Use XIRR, not absolute returns. A ₹10,000/month SIP showing "15% return" on the app might actually be 11% XIRR — or 18%. Absolute numbers lie for SIPs
- Compare to benchmark, not to other funds. If your fund matches its benchmark within 1-2%, it's doing its job. The topper list changes every year
- Judge over 5+ years, not months. Equity SIPs will show negative returns during corrections — that's the engine working, not failing
- The biggest SIP failure isn't poor returns — it's stopping too early. The median SIP in India lasts 3.5 years. Wealth is built after year 7
You’re Asking the Wrong Question
“Is my SIP working?” usually means “I opened my app, saw a number, and it didn’t feel like enough.” That feeling is the problem. Not the SIP.
Here’s what typically happens: You start a ₹10,000/month SIP. After 8 months, you’ve invested ₹80,000. Your current value is ₹78,500. You think: “I’ve lost money. This isn’t working.”
But your first installment is up 7%. Your second is up 5%. Your third is flat. Your most recent installments are slightly down because markets dipped last week. The blended number looks disappointing because your newest money hasn’t had time to work yet.
This is the “SIP illusion” — your latest installments always drag down the headline number, especially in the first 1-3 years.
72% of Indian SIP investors judge performance by looking at absolute returns on their app dashboard. This number doesn't account for the timing of each installment. XIRR is the only accurate way to measure SIP returns — and most investors have never calculated it.
The Right Way to Measure: XIRR
XIRR (Extended Internal Rate of Return) is the only honest metric for SIPs. Here’s why:
When you invest ₹10,000/month for 3 years, your first installment has been invested for 36 months. Your last installment has been invested for 1 month. An absolute return calculation treats them equally. XIRR weights them by how long each rupee has been at work.
Example:
| Metric | Shows | Reality |
|---|---|---|
| App shows “12% return” | Feels okay | Could be 8% XIRR (bad) or 15% XIRR (great) — you can’t tell |
| XIRR shows 13.5% | Annualised rate considering all cash flows | This is your real return. Compare it to the benchmark |
| Benchmark (Nifty 50) XIRR: 12.8% | What you’d earn with zero fund selection skill | Your fund beat the benchmark by 0.7%. It’s working |
How to calculate XIRR:
- Most investment apps (Groww, Kuvera, Coin) show XIRR in your portfolio dashboard
- Value Research Online and Morningstar portfolio trackers calculate it automatically
- In Excel/Google Sheets:
=XIRR(cash_flows, dates)with your SIP amounts as negative values and current value as positive
The Three Tests Your SIP Should Pass
Test 1: Benchmark Comparison (3-5 year window)
Every mutual fund has a benchmark index. A large-cap fund benchmarks against Nifty 50. A flexi-cap benchmarks against Nifty 500. A mid-cap benchmarks against Nifty Midcap 150.
Your fund should match or beat its benchmark over a 3-5 year rolling period. Not every quarter. Not every year. Over a full market cycle.
| Fund vs. Benchmark | Verdict |
|---|---|
| Beats benchmark by 1-3% over 5 years | Excellent. Keep it |
| Matches benchmark (within 1%) over 5 years | Good. Fine to keep, or switch to a cheaper index fund |
| Underperforms benchmark by 2%+ over 5 years | Problem. Consider switching to index fund in same category |
Why this matters: If your active fund consistently underperforms its index after fees, you’re paying extra for worse results. A Nifty 50 index fund at 0.1% expense ratio will do better than most large-cap active funds charging 1-1.5%.
Test 2: Goal Progress Check
Your SIP exists to fund a goal. A retirement corpus. A child’s education. A house down payment. The real question isn’t “what’s my return?” — it’s “am I on track?”
Simple goal tracking:
- Define your target corpus (e.g., ₹2 crore in 15 years)
- Assume 12% CAGR for equity SIPs (conservative long-term average)
- Calculate required monthly SIP using any online calculator
- Compare actual portfolio value to the projected value at this point in time
- If you’re within 10% of projected, you’re on track
Investors who track goal progress instead of daily returns are 4x less likely to stop their SIPs during market corrections (AMFI behavioral study, 2023). When you frame the question as "am I on track for retirement?" instead of "did I lose money this month?", the answer is almost always yes — even during corrections. Framing changes behavior.
Test 3: Fund Category Check
Sometimes the problem isn’t the fund — it’s the category. If you started a small-cap SIP 18 months ago and it’s down 10%, that doesn’t mean the fund is bad. Small-caps as a category might be in a correction. Check:
- Is your fund performing in line with its category average?
- Is the category itself in a cyclical downturn?
- Has the fund manager changed recently?
If your fund is in line with its category, and the category is temporarily down, the SIP is working exactly as designed — buying cheap units during the dip.
When to Actually Worry
Most of the time, “is my SIP working?” is anxiety, not a real problem. But there are legitimate red flags:
-
Fund consistently underperforms benchmark by 2%+ over 3-5 years. Not 6 months. Not 1 year. Consistently over a full cycle. This suggests a structural problem with the fund management.
-
Fund manager changed and new manager has a different style. The track record you relied on belongs to the old manager. Monitor for 12-18 months after a change.
-
Fund category no longer fits your goal timeline. If you started a small-cap SIP for a goal that’s now 2 years away, the volatility is inappropriate. Switch to a debt or hybrid fund for near-term goals.
-
You can’t explain why you own the fund. If you started a SIP because a YouTube video said so and you don’t know its benchmark, category, or how it fits your portfolio, take 30 minutes to evaluate — then decide to keep or consolidate.
The single best predictor of SIP success isn't fund selection — it's duration. An investor who picks an average fund and holds for 15 years almost always outperforms an investor who picks the "best" fund and switches every 2 years. Consistency beats brilliance in compounding.
The Performance-Chasing Trap
This is the real danger lurking behind “is my SIP working?” — the temptation to switch.
You see a fund topper list. Your fund returned 18% last year. The topper returned 32%. You feel like you’re leaving money on the table. You switch.
Here’s what actually happens:
- You pay capital gains tax on the switch (12.5% on LTCG)
- You reset your compounding clock
- The fund you switched to was the topper because its category was hot. By the time you switch in, the cycle has often peaked
- Next year, your old fund is the topper. The cycle repeats.
SEBI data shows that the average Indian equity mutual fund investor earns 2-3% less CAGR than the fund itself — not because the fund underperforms, but because investors buy after the fund has rallied and sell after it dips. This behavior gap is the most expensive "tax" in investing, and it's entirely self-inflicted.
What You Should Actually Do
- Calculate XIRR on each fund. Use your app or Value Research. This is your real return.
- Compare to benchmark, not to toppers. If XIRR is within 1-2% of benchmark over 3 years, the fund is fine.
- Check goal progress once a year. Are you on track for your target corpus? If yes, stop worrying.
- Don’t check more than quarterly. Every extra login is a chance to make an emotional decision.
- If a fund truly underperforms benchmark over 3-5 years, switch to an index fund in the same category. Not to the current topper. To the index.
