Type “SIP calculator ₹2 crore” into Google and you’ll get five different “right” answers within the first five results.
₹86,100 a month. ₹89,271 a month. ₹90,118 a month. All claiming the same 12% return, the same 10-year target.
None of them are lying to you. They’re just quietly using different math — and almost none of them tell you that.
This article gives you the actual numbers, explains exactly why calculators disagree, and — more importantly — shows you something almost no SIP calculator bothers to mention: what that ₹2 crores will actually be worth by the time you get there.

The Quick Answer: Monthly SIP Needed for ₹2 Crore
Assuming an illustrative 12% annual return — a commonly used long-term assumption for diversified equity mutual funds, not a promised or guaranteed number — here’s what a monthly SIP needs to be to reach ₹2 crores:
| Tenure | Required monthly SIP | Total invested | Wealth gained |
|---|---|---|---|
| 10 years | ₹89,271 | ₹1.07 crore | ₹92.9 lakh |
| 15 years | ₹42,023 | ₹75.6 lakh | ₹1.24 crore |
| 20 years | ₹21,743 | ₹52.2 lakh | ₹1.48 crore |
| 25 years | ₹11,749 | ₹35.2 lakh | ₹1.65 crore |
These figures are illustrative, based on an assumed 12% annual rate of return, and are not guaranteed. Mutual fund investments are subject to market risk, and actual SIP returns will vary depending on market conditions and the specific funds chosen.
Look at how much of the 25-year corpus is actually wealth created by compounding, not money you put in — nearly 82%. That’s the entire case for starting early, in one line.
Why Your Number Might Not Match Other SIP Calculators
This is worth understanding properly, because it’s the single biggest source of confusion in SIP planning — more than the return assumption itself.
A “12% annual return” can be converted into a monthly rate two different ways, and most calculators don’t tell you which one they used.
- Nominal monthly rate: simply divide 12% by 12, giving 1% a month. Simple, but not quite how compounding actually works.
- Effective monthly rate: the monthly rate that, compounded 12 times, actually equals 12% a year — about 0.949% a month. Mathematically more accurate.
The figures in the table above use the effective-monthly-rate method, with each SIP instalment treated as invested at the start of the month (so it gets a full month’s growth immediately) — the same methodology we use consistently across every SIP and SWP illustration on this site.
A calculator using the simpler nominal-rate method will show a slightly lower required SIP — for 10 years, around ₹86,100 instead of ₹89,271. Neither number is “wrong”; they’re answering the question with two different conventions.
The practical takeaway: treat any single calculator’s output as a close estimate, not a precise commitment. Small differences in method matter far less than actually starting your SIP and reviewing it periodically with a professional.
The Step-Up SIP Trick: Reach ₹2 Crore Starting Much Smaller
Committing to ₹89,271 a month from day one is unrealistic for most people early in their career — but it doesn’t have to be that way.
A step-up SIP (also called a top-up SIP) increases your monthly instalment by a fixed percentage every year, usually in line with rising income.
Here’s what a 10% annual step-up does to the starting monthly amount needed for ₹2 crores, at the same illustrative 12% return:
| Tenure | Flat SIP (no step-up) | Step-up SIP (10% p.a. increase) — starting amount |
|---|---|---|
| 10 years | ₹89,271 | ₹61,183 |
| 15 years | ₹42,023 | ₹24,170 |
| 20 years | ₹21,743 | ₹10,735 |
| 25 years | ₹11,749 | ₹5,082 |
Over a 20-year horizon, a step-up SIP lets you start at roughly half the flat-SIP amount — because your later, larger instalments do more of the heavy lifting as your income grows.
The trade-off: you need the discipline to actually increase the SIP every year, not just set it and forget it.
This is exactly the kind of ongoing tracking a Certified Financial Planner typically helps clients stay consistent with.
What If You Can Only Invest ₹1,000, ₹5,000 or ₹10,000 a Month?
Not everyone is planning around a ₹2 crore target from month one. A lot of people simply want to know: what does a round, affordable SIP amount actually turn into?
Here’s the same 12% illustrative return, applied to three common starting amounts:
| Monthly SIP | 5 years | 10 years | 15 years | 20 years | 25 years |
|---|---|---|---|---|---|
| ₹1,000 | ₹81,104 | ₹2.24 lakh | ₹4.76 lakh | ₹9.20 lakh | ₹17.02 lakh |
| ₹5,000 | ₹4.06 lakh | ₹11.20 lakh | ₹23.80 lakh | ₹45.99 lakh | ₹85.11 lakh |
| ₹10,000 | ₹8.11 lakh | ₹22.40 lakh | ₹47.59 lakh | ₹91.99 lakh | ₹1.70 crore |
Illustrative figures at an assumed 12% annual return, not guaranteed. Actual outcomes depend on market performance and fund selection.
Notice something useful here: a ₹10,000 monthly SIP for 25 years gets you most of the way to ₹2 crores on its own. You don’t need to start big — you need to start, and stay consistent for long enough.
The Number Nobody Warns You About
Here’s the question almost every SIP calculator skips entirely: will ₹2 crores, twenty years from now, actually feel like ₹2 crores feels today?
No. Not even close.
The RBI’s official inflation target is 4% CPI inflation, with a tolerance band of 2–6%, retained for the 2026–2031 period.
Financial planners commonly use a more conservative 6% assumption — the upper end of that band — for long-term planning, precisely to avoid underestimating this effect.
At a 6% assumed inflation rate, here’s what your future ₹2 crore is actually worth in today’s purchasing power:
| Year you reach ₹2 crore | Value in today’s money (at 6% inflation) |
|---|---|
| After 10 years | ₹1.12 crore |
| After 15 years | ₹83.5 lakh |
| After 20 years | ₹62.4 lakh |
| After 25 years | ₹46.6 lakh |
Illustrative, based on an assumed 6% annual inflation rate — a commonly used planning assumption, not an official forecast. Actual inflation will vary year to year.
This isn’t a reason to feel discouraged — it’s a reason to plan for a bigger number. If your real goal is “₹2 crore of today’s purchasing power” in 20 years, your actual target should be closer to ₹6.4 crore in future rupees, not ₹2 crores.
This is precisely why “what corpus do I need” and “how much is my future corpus actually worth” have to be answered together — and why a fixed target picked in isolation, however satisfying the round number feels, can quietly leave you short.
Once You’ve Built It: Turning ₹2 Crore into a Monthly Income
Building the corpus is only half the plan. Sooner or later, the question flips from “how do I grow this” to “how do I draw an income from this without running out.”
The tool for that is a Systematic Withdrawal Plan (SWP) — you stay invested, and a fixed amount is redeemed and paid to you every month while the rest keeps growing.
As an illustration: a fully invested ₹2 crore corpus, drawn down through an SWP of ₹1,00,000 a month at an assumed 8% annual return, would still be worth roughly ₹3.92 crore after 20 years — the withdrawal rate is comfortably below what the corpus earns.
Illustrative, based on an assumed 8% annual return. Not guaranteed — mutual fund returns are market-linked and subject to market risk.
Common Mistakes People Make with SIP Calculators
- Treating the return assumption (12%, or any number) as a promise rather than an illustration — equity returns are never guaranteed.
- Comparing two calculators’ outputs without checking whether they use the same monthly-rate convention (see the section above).
- Picking a fixed rupee target (“₹2 crores”) without adjusting it for what that amount will actually be worth by the time they reach it.
- Starting a Step-up SIP and then never actually increasing it — the plan only works if the step-up genuinely happens each year.
- Ignoring taxation on withdrawals when eventually converting the corpus into income via a Lumpsum withdrawal or SWP.
Regular Plan or Direct Plan? What the Data Actually Shows
Once the maths is sorted, the next real decision is which plan to actually invest through — Direct or Regular.
A Direct plan has a lower expense ratio, which is a mathematical fact. But a lower cost only helps if you actually stay invested through the SIP’s full tenure — and that’s where the data gets interesting.
Long-tenure SIP accounts (over five years old) in Direct plans fell by 34.69% year-on-year, compared to just 4.41% in Regular plans over the same period.
In practical terms: investors guided by a distributor or advisor are considerably more likely to stay invested through market ups and downs — and staying invested through a full market cycle matters far more to your final corpus than a fractional difference in expense ratio that gets abandoned at the first downturn.
This isn’t a case against Direct plans on principle — it’s a case for whichever plan you’ll actually stick with for 15–25 years without panic-selling.
A Quick SIP Planning Checklist
- Decide your real target in today’s rupees first, then inflate it forward to your actual future target — not the other way around.
- Pick a realistic tenure based on your actual goal (retirement age, a child’s education, and so on), not a round number.
- If starting small, build in an annual step-up rather than waiting until you can afford the “full” SIP amount.
- Review your asset allocation periodically — a 12% assumption only holds up with a genuinely equity-oriented portfolio, held long enough.
- Decide upfront whether you’ll invest via Direct or Regular, based on your own likelihood of staying invested through volatility, not just the expense ratio.
The Bottom Line
A ₹2 crore SIP target is a perfectly reasonable goal — but the honest version of this plan has three parts most calculators skip: understanding why calculators disagree, planning for what that ₹2 crores will really be worth, and having a real plan for turning it into income once you get there.
Good investing begins with good planning — the SIP amount is just the easiest part to calculate.
If you’d like these numbers mapped against your own income, goals, and timeline — rather than a generic illustration — a Certified Financial Planner can build that out with you.
You can start with an Initial Guidance Call (No Cost) to see what your own number should actually be.
Frequently Asked Questions
Q1. How much SIP do I need per month to build ₹2 crores in 20 years?
At an illustrative 12% annual return, roughly ₹21,743 a month for 20 years. This is based on an assumed rate of return and is not guaranteed — actual figures will vary with market performance.
Q2. Why do different SIP calculators give different answers for the same amount and return?
Most of the difference comes from how the annual return is converted into a monthly rate — some calculators use a simple nominal rate (12% ÷ 12), others use the mathematically precise effective monthly rate. Both are valid conventions, but they produce slightly different numbers for the same stated return.
Q3. What if I can only invest ₹5,000 or ₹10,000 a month — can I still reach ₹2 crores?
A ₹10,000 monthly SIP for 25 years grows to roughly ₹1.70 crore at an illustrative 12% return — close to the target on its own. Starting smaller and increasing your SIP over time (a step-up SIP) is a realistic way to close the rest of the gap.
Q4. What is a step-up SIP, and how much does it actually help?
A step-up SIP increases your monthly investment by a fixed percentage every year, usually matching salary growth. For a 20-year, ₹2 crore target, a 10% annual step-up can roughly halve the SIP amount you need to start with, compared to a flat SIP.
Q5. Will ₹2 crore in 20–25 years have the same value as ₹2 crores today?
No. At a commonly assumed 6% inflation rate, a ₹2 crore corpus reached in 20 years would be worth roughly ₹62 lakhs in today’s purchasing power. It’s worth targeting a larger future corpus if ₹2 crore of today’s value is the real goal.
Q6. Once I’ve built my ₹2 crore, how do I convert it into a monthly income?
A Systematic Withdrawal Plan (SWP) lets you stay invested while withdrawing a fixed amount every month, with the remaining corpus continuing to grow. The sustainable withdrawal amount depends on your assumed rate of return and how long the income needs to last.
