At a 12% annual return, a SIP of about ₹10,900 a month reaches ₹1 crore in 20 years, and about ₹3,250 a month gets there in 30. Plan at a more cautious 10% and the 20-year figure rises to about ₹13,800 a month.
The answer depends on three inputs: how much you invest each month, for how long, and what return you earn. You control the first two. The third is uncertain. This guide works through the real numbers, shows the method so you can check them, and explains what ₹1 crore will actually buy when you get there.
How we calculated everything here. All figures assume the SIP is paid at the start of each month and grows at a monthly rate equivalent to the stated annual return (for 12% a year that is 1.12 raised to the power 1/12, minus 1, or about 0.949% a month, not 1%). This is the same convention our SIP calculator uses. Returns are before tax and before any exit load. They are illustrations, not forecasts.
How Long Does It Take to Reach ₹1 Crore at 12%?
| Monthly SIP | Time to ₹1 crore | Total invested | Wealth gained |
|---|---|---|---|
| ₹3,000 | 30 years 9 months | ₹11.1 lakh | ₹89.8 lakh |
| ₹5,000 | 26 years 5 months | ₹15.9 lakh | ₹85.0 lakh |
| ₹10,000 | 20 years 8 months | ₹24.8 lakh | ₹75.2 lakh |
| ₹15,000 | 17 years 7 months | ₹31.7 lakh | ₹69.4 lakh |
| ₹25,000 | 13 years 10 months | ₹41.5 lakh | ₹59.5 lakh |
Two things stand out. First, small SIPs do get there, but slowly: ₹3,000 a month needs more than 30 years. Second, the longer the horizon, the bigger the share of the final ₹1 crore that comes from growth rather than from your own money. At ₹3,000 a month you put in ₹11 lakh; at ₹25,000 a month you put in ₹41 lakh for the same target.
Monthly SIP Needed for ₹1 Crore, by Horizon and Return
If you have a deadline in mind, flip the question: how much do you need to invest each month? The table shows three return assumptions, because nobody knows which one you will get.
| Years | At 8% a year | At 10% a year | At 12% a year | Total invested at 12% |
|---|---|---|---|---|
| 10 | ₹55,200 | ₹49,600 | ₹44,600 | ₹53.6 lakh |
| 15 | ₹29,400 | ₹24,900 | ₹21,000 | ₹37.8 lakh |
| 20 | ₹17,500 | ₹13,800 | ₹10,900 | ₹26.1 lakh |
| 25 | ₹10,900 | ₹8,000 | ₹5,900 | ₹17.6 lakh |
| 30 | ₹7,100 | ₹4,800 | ₹3,250 | ₹11.7 lakh |
Read across any row and the return assumption matters a lot. Over 20 years, the difference between 8% and 12% is ₹6,600 a month. Over 30 years, an 8% return needs more than twice the SIP that 12% does. That is why it is safer to plan with a conservative return and treat anything better as a bonus.
The same uncertainty affects time. A ₹5,000 SIP reaches ₹1 crore in 26 years 5 months at 12%, but takes about 29 years 8 months at 10%, 31 years 8 months at 9% and 34 years 2 months at 8%.
What Return Is Reasonable to Assume?
Many SIP articles use 12% as if it were a fact. It is an assumption. For a real-world reference point, the regular plan of a Nifty 50 index fund, a broad and low-cost way to own large Indian companies, returned about 11.0% a year over 10 years, 11.5% over 15 years and 10.2% over 20 years, to 28 September 2026 (based on AMFI NAV data). That is a lump-sum return; your own SIP return will differ depending on when each instalment went in. You can measure the actual return on your SIP with an XIRR calculator, which handles cash flows on different dates. Our guide to XIRR vs CAGR explains why the two differ.
A reasonable approach is to plan at 10% and check your progress every year. If markets are kind, you reach the target early.
Step-Up SIP: The Biggest Lever You Control
Most people's income rises over time, so a fixed SIP becomes a smaller share of income every year. A step-up SIP raises the monthly amount by a fixed percentage once a year. The effect is large:
- ₹5,000 a month, flat, at 12%: ₹1 crore in 26 years 5 months.
- ₹5,000 a month, stepped up 10% every year, at 12%: ₹1 crore in about 20 years 6 months. You reach the goal roughly six years sooner, and invest about ₹36.4 lakh along the way.
- ₹10,000 a month for 20 years, at 12%: about ₹92 lakh flat, but about ₹1.86 crore with a 10% annual step-up (you invest ₹68.7 lakh instead of ₹24 lakh).
Put the other way, here is the starting SIP that reaches ₹1 crore at 12% if you raise it by 10% every year:
| Years | Starting SIP (10% step-up) | Flat SIP for comparison |
|---|---|---|
| 10 | ₹30,600 | ₹44,600 |
| 15 | ₹12,100 | ₹21,000 |
| 20 | ₹5,370 | ₹10,900 |
| 25 | ₹2,540 | ₹5,900 |
A step-up lets you start smaller, but you will invest more in total because the later instalments are large. Try your own numbers in the step-up SIP calculator, or see a longer example in our post on building ₹2 crore with a step-up SIP.
Why Starting Early Matters So Much
A ₹10,000 SIP at 12% grows to about ₹92 lakh in 20 years but about ₹3.08 crore in 30 years. The extra ten years add ₹12 lakh of your money and more than ₹2 crore of value. Most of a long SIP's final value is built in the last few years, which is why stopping or pausing in the last few years is so costly.
₹1 Crore Later Is Not ₹1 Crore Today
Inflation is the part most crorepati maths skips. If prices rise 6% a year (an assumption, not a forecast), ₹1 crore received in the future buys what this much buys today:
| ₹1 crore received in | Worth in today's money (6% inflation) |
|---|---|
| 10 years | ₹55.8 lakh |
| 15 years | ₹41.7 lakh |
| 20 years | ₹31.2 lakh |
| 25 years | ₹23.3 lakh |
| 30 years | ₹17.4 lakh |
If you want the purchasing power of ₹1 crore today, the target grows with the horizon, and so does the SIP:
| Years | Target in future rupees | Flat monthly SIP at 12% |
|---|---|---|
| 10 | ₹1.79 crore | ₹79,900 |
| 15 | ₹2.40 crore | ₹50,400 |
| 20 | ₹3.21 crore | ₹34,900 |
| 25 | ₹4.29 crore | ₹25,200 |
| 30 | ₹5.74 crore | ₹18,600 |
So treat "₹1 crore" as a milestone, not a finish line. If the money is for a specific goal such as retirement, plan for the goal in today's prices and convert it with an inflation calculator.
Volatility: The Part the Tables Hide
The tables assume a smooth return every month. Real equity returns are lumpy. Based on AMFI NAVs of Nifty 50 index funds:
- 2008: the index fell about 60% from its January 2008 high to October 2008. NAVs only rose sustainably above that January 2008 peak in late 2013, almost six years later.
- 2020: the fall was about 38%, and the previous high was regained within about ten months. From the March 2020 low to June 2021, the index fund NAV more than doubled (about +109%).
An SIP that kept running through 2008 or 2020 bought units cheaply during the fall. An SIP that was stopped in March 2020 missed most of the recovery. We look at this in detail in should you pause your SIP in a market crash. The practical point: if your deadline is less than five to seven years away, an all-equity SIP can easily miss a fixed target, and many investors gradually move money to debt as the goal approaches.
Tax When You Reach ₹1 Crore
Equity mutual fund gains held for more than 12 months are long-term capital gains, taxed at 12.5% on gains above ₹1.25 lakh in a year, plus 4% cess (section 198 of the Income-tax Act, 2025, from tax year 2026-27; the same rate applied to sales from 23 July 2024 under the old Act). Units held for 12 months or less are taxed at 20%.
Illustration: a ₹10,900 SIP for 20 years invests about ₹26.1 lakh and reaches ₹1 crore, a gain of about ₹73.9 lakh. Redeemed all in one tax year, the tax would be (₹73.9 lakh − ₹1.25 lakh) × 12.5% × 1.04 ≈ ₹9.4 lakh. Redeeming in stages across several tax years uses the ₹1.25 lakh exemption more than once and lowers the total. Each SIP instalment has its own purchase date, so units bought in the last 12 months are short-term.
If you invest through ELSS funds, contributions up to ₹1.5 lakh a year qualify for a deduction under section 123 (old 80C) only if you are in the old tax regime. ELSS units have a three-year lock-in per instalment.
A Simple Plan
- Pick the horizon and a conservative return (say 10%) and read the monthly SIP from the table above, or work it out in the SIP calculator.
- If that amount is too high now, start lower and add a step-up you can sustain.
- Decide whether you want ₹1 crore in future rupees or the value of ₹1 crore today, and adjust the target.
- Check your actual XIRR once a year, and raise the SIP if you are behind.
- Keep the SIP running through falls, and move towards safer assets as the deadline nears.
