Key takeaways
- ~₹10,000/month for 10 years at 12% (illustrative) reaches ₹1 crore.
- Time matters more than amount — starting 5 years earlier can halve your SIP.
- A 10% yearly step-up SIP reaches the goal years faster.
The exact numbers (at an assumed 12% p.a.)
| Timeline | Monthly SIP needed | You invest |
|---|---|---|
| 20 years | ~₹1,000 | ~₹2.4 lakh |
| 15 years | ~₹2,000 | ~₹3.6 lakh |
| 10 years | ~₹4,300 | ~₹5.2 lakh |
| 7 years | ~₹8,000 | ~₹6.7 lakh |
| 5 years | ~₹12,500 | ~₹7.5 lakh |
These are illustrative projections at a constant 12% annual return — actual market returns will vary, and mutual fund investments are subject to market risks. The pattern is what matters: time is the biggest lever you have.
The step-up SIP trick
Instead of a flat SIP, increase it 10% every year as your salary grows. A ₹10,000 SIP stepped up 10% yearly can reach ₹1 crore years earlier than a flat ₹10,000 — with the same starting effort. Most investors can step up; few do. Automate it.
What can go wrong
Assuming 12% forever (returns fluctuate), stopping SIPs in a crash (when units are cheapest), and picking the wrong fund for your horizon. A yearly review with an AMFI-registered advisor keeps the plan on track — and it's free.
