SIP Calculator Guide â How â¹5,000/month Becomes â¹1 Crore (Step-Up SIP Comparison)
Last verified: April 2026, with rolling 10-15 year category averages from SEBI/AMFI data and standard SIP compounding math.
“Start a â¹5,000 SIP and you’ll have â¹1 crore” is one of the most repeated claims in Indian financial media. It’s true â at 12% annual return, â¹5,000 monthly compounds to â¹1.04 crore in 26 years. But that’s a long road, and small tweaks change the timeline dramatically: a step-up SIP at 10% annual increase reaches the same â¹1 crore in 19 years, with only â¹13 lakh more invested. This guide walks through the math, return assumptions, and the four levers that actually matter for getting to your first crore.
The flat â¹5,000/month SIP â the base case
| Years | Total invested | Final corpus (12% CAGR) | Wealth gain |
|---|---|---|---|
| 5 | â¹3,00,000 | â¹4,12,432 | â¹1,12,432 |
| 10 | â¹6,00,000 | â¹11,61,695 | â¹5,61,695 |
| 15 | â¹9,00,000 | â¹25,22,880 | â¹16,22,880 |
| 20 | â¹12,00,000 | â¹49,95,740 | â¹37,95,740 |
| 25 | â¹15,00,000 | â¹94,88,200 | â¹79,88,200 |
| 26 | â¹15,60,000 | â¹1,07,30,000 | â¹91,70,000 |
| 30 | â¹18,00,000 | â¹1,76,57,000 | â¹1,58,57,000 |
Notice how the curve steepens. Years 1-10 give you â¹11.6 L. Years 20-26 alone add another â¹57 L. This is compounding doing its asymmetric work â early years feel slow, later years feel magical. The investor who quits at year 15 because “the returns aren’t great” walks away from 80% of the wealth.

The step-up SIP â same monthly start, much faster finish
A step-up (or top-up) SIP increases your monthly contribution by a fixed percentage every year. The simple version: â¹5,000 in year 1, â¹5,500 in year 2 (10% step-up), â¹6,050 in year 3, and so on. Most AMC platforms support this natively â set it once, forget it.
| Step-up rate | Years to â¹1 Cr (start â¹5K) | Total invested over those years |
|---|---|---|
| 0% (flat) | 26 | â¹15.6 L |
| 5% annual step-up | 22 | â¹22.4 L |
| 10% annual step-up | 19 | â¹28.5 L |
| 15% annual step-up | 17 | â¹35.2 L |
The math behind 10% step-up working so well: a 10% annual SIP increase tracks roughly with salary growth, so the contribution feels constant in real terms. By year 19, you’re SIPing ~â¹30,000/month â comfortable for someone whose salary has grown alongside.
What return rate should you assume?
The 12% number is the long-term Indian equity historical average. But “long-term” matters â short windows can be wildly off.
| Index / category | Rolling 10-year CAGR | Rolling 15-year CAGR |
|---|---|---|
| Nifty 50 TRI | ~12-14% | ~13-15% |
| Nifty Midcap 150 TRI | ~14-17% | ~15-18% |
| Nifty Smallcap 250 TRI | ~13-18% | ~14-19% |
| Flexi-cap MF average | ~12-14% | ~13-15% |
| ELSS category average | ~12-14% | ~13-15% |
Use 12% as a planning anchor for diversified equity. If you’re going midcap- or smallcap-heavy, 14-15% is more honest. Don’t use 18% â that’s bull-market-end thinking and it overstates expectations.
The four levers that change everything
Lever 1 â Time
The most powerful. Going from 20-year SIP to 25-year SIP nearly doubles the corpus (â¹50 L â â¹95 L). Going from 25 to 30 years almost doubles it again. Start early; even â¹2,000/month at age 23 beats â¹10,000/month at age 35.
Lever 2 â Contribution
Linear effect. â¹10K instead of â¹5K doubles the corpus at every duration. But the trick is sustainability â many people start â¹15K SIPs and stop within a year. Better to start at â¹5K and step up than to over-commit.
Lever 3 â Return rate
Non-linear. Going from 10% to 12% adds ~30% more wealth at 25 years; 12% to 14% adds another 30%. Picking decent funds matters â but don’t chase fund-of-the-year. The category average is fine.
Lever 4 â Avoiding panic
An SIP that runs through 2008, 2013, 2016, 2020 corrections without stoppage delivers the historical 12%. An SIP that stops during corrections forfeits the cheapest units it would have bought. The single biggest determinant of long-term returns isn’t fund selection â it’s not stopping the SIP.
Worked plan â â¹1 Cr in 15 years (for someone starting at 30)
To hit â¹1 crore in 15 years at 12% CAGR, you need to invest:
- Flat SIP: â¹19,820/month for 15 years (â¹35.7 L invested â â¹1 Cr)
- Step-up SIP: Start â¹13,500/month, 10% annual step-up (~â¹40 L invested â â¹1 Cr)
- Lump-sum + flat SIP: â¹5 L lump-sum today + â¹13,000/month flat â â¹1 Cr in 15 years
If 15 years is too short, stretch to 20 â the required SIP drops to â¹10,000/month flat or â¹6,500/month with 10% step-up.
Where should the SIP go?
For a beginner aiming at â¹1 Cr in 20+ years:
- 60% in a flexi-cap or large-and-midcap MF â the steady core
- 20% in a midcap or smallcap MF â the growth kicker (higher volatility)
- 10% in international diversification â Nasdaq 100 or US S&P 500 fund-of-fund
- 10% in an ELSS if you’re claiming Section 80C in the old regime â see 80C ranking
Direct plans (lower expense ratio) over regular plans. Index funds are perfectly fine â Nifty 50 + Nifty Next 50 + Nifty Midcap 150 covers 90% of what active funds give, with lower cost and zero manager risk.
Tax on SIP redemptions
Equity MF redemptions follow the new capital gains rules: STCG 20% if redeemed within 12 months, LTCG 12.5% on gains above â¹1.25 L per year if held over 12 months. Each SIP installment has its own holding-period clock â FIFO for equity MFs.
The â¹1 Cr corpus from a 25-year SIP, redeemed at retirement, would have ~â¹85 L of LTCG. Spread the redemption across 5 years (â¹20 L per year, â¹17 L gains, exemption â¹1.25 L) and effective tax drops to ~12.5% à ~â¹15.75 L per year à 5 = ~â¹9.85 L total â versus ~â¹10.5 L if redeemed in one shot. Modest difference; the bigger principle is don’t liquidate equity in a market crash if you can help it.

FAQs
Is 12% return realistic for SIPs?
Over 15+ year windows in Indian equity, yes â that’s the historical average for diversified equity mutual funds and broad indices. Over short windows (1-3 years), returns can be -20% to +40%. Don’t anchor on the recent past.
What’s the difference between SIP and lump-sum investing?
SIP averages your purchase cost across market levels (rupee-cost averaging). Lump-sum invests once and rides the full market path. Mathematically, lump-sum wins ~70% of the time over 10-year windows because markets trend up. But SIP is psychologically easier and matches monthly cash flow, which is why it dominates retail behaviour.
Should I do SIP in 1 fund or 5 funds?
1 well-chosen flexi-cap or 1-2 index funds is enough for 90% of investors. Beyond 4-5 schemes, you’re just buying overlapping holdings at higher tracking complexity. Avoid the “12 SIPs of â¹500 each” approach.
Can I pause my SIP?
Most AMC platforms allow pausing for 1-3 months. Use it for genuine cash-flow gaps; don’t use it to “time” markets â that’s how you miss the rebound.
Is step-up SIP worth the complication?
Yes â set-and-forget. The 10% step-up trims 7 years off your â¹1 Cr timeline at the cost of contributions you’d be making anyway as your salary grows. Most platforms now support automatic annual step-ups.
What if I want â¹1 Cr in 10 years?
You need â¹43,500/month flat at 12% CAGR. Or â¹30,000/month with 10% step-up. Aggressive but doable for a senior professional. Realistically, equity returns over a 10-year window can deliver less than 12% â keep a buffer.
