A Systematic Investment Plan (SIP) invests a fixed amount in a mutual fund at regular intervals. India had more than 10 crore active SIP accounts and monthly SIP inflows of about ₹32,297 crore in August 2026.
Key takeaways
- SIPs buy more units when prices fall and fewer when they rise (rupee-cost averaging).
- Discipline and time — not market timing — drive most SIP results.
- A step-up SIP that rises with income can dramatically increase the final corpus.
- SIPs reduce timing risk but do not remove market risk.
Rupee-cost averaging example
| Month | Invested | NAV | Units |
|---|---|---|---|
| 1 | ₹5,000 | ₹50 | 100.00 |
| 2 | ₹5,000 | ₹40 | 125.00 |
| 3 | ₹5,000 | ₹45 | 111.11 |
| Total | ₹15,000 | Avg cost ₹44.63 | 336.11 |
The average cost (₹44.63) is lower than the average NAV (₹45).
What a ₹10,000 monthly SIP can grow to (assumed 12% p.a.)
| Years | Invested | Estimated value |
|---|---|---|
| 5 | ₹6 lakh | ≈ ₹8.2 lakh |
| 10 | ₹12 lakh | ≈ ₹23.2 lakh |
| 15 | ₹18 lakh | ≈ ₹50.5 lakh |
| 20 | ₹24 lakh | ≈ ₹99.9 lakh |
With a 10% yearly step-up, 15 years of SIP starting at ₹10,000 grows to about ₹86.8 lakh at the same assumed return.
Choosing the SIP amount
- Define the goal and its future cost (adjust for inflation).
- Use the goal SIP calculator.
- Start with what you can sustain; step up every year.
Common mistakes
- Stopping SIPs when markets fall — that is when averaging helps most.
- Too many funds with overlapping portfolios.
- Choosing funds on last year's return.
Your action checklist
- Define the goal, horizon and risk you can take.
- Pick the category first, then compare 2–3 funds on consistency and cost.
- Prefer direct plans if you do not need a distributor.
- Start a SIP with auto-debit and step it up yearly.
- Review once a year and rebalance instead of reacting to short-term moves.
