Reaching a ₹1 crore corpus is mostly a question of how long you stay invested. As a rough guide, you would need to invest approximately ₹43,000 per month for 10 years, ₹20,000 for 15 years, ₹10,000 for 20 years, or just around ₹2,900 for 30 years — assuming a roughly 12% annualised return. The longer your runway, the smaller the monthly cheque, because compounding does the heavy lifting.
This guide breaks down the numbers across different tenures and return assumptions, shows why starting early is the single biggest lever you have, and explains where these returns realistically come from. All figures are illustrative — market-linked returns are never guaranteed.
The short answer: a worked table
The table below shows the approximate monthly SIP (Systematic Investment Plan) required to accumulate ₹1 crore, for different investment horizons and assumed annual returns. These are rounded, illustrative figures calculated using the standard SIP compounding formula.
| Tenure | At ~10% p.a. | At ~12% p.a. | At ~14% p.a. |
|---|---|---|---|
| 10 years | ₹48,800 | ₹43,500 | ₹38,600 |
| 15 years | ₹24,100 | ₹20,000 | ₹16,500 |
| 20 years | ₹13,200 | ₹10,100 | ₹7,700 |
| 25 years | ₹7,500 | ₹5,300 | ₹3,700 |
| 30 years | ₹4,400 | ₹2,900 | ₹1,800 |
A few things jump out immediately:
- Time matters more than rate. At 12%, going from a 10-year to a 30-year horizon cuts your monthly outlay by roughly 93% (₹43,500 down to ₹2,900). Bumping the return from 10% to 14% over the same 30 years cuts it by far less.
- Returns are assumptions, not promises. Equity mutual funds in India have historically delivered double-digit returns over long periods, but any single decade can be very different. Always plan with a conservative number.
You can model your own numbers — change the SIP, tenure, or return — with our SIP calculator, and build a full goal-based plan using the financial life planner.
Why starting early is the biggest lever
The reason the 30-year column is so much smaller than the 10-year column is compounding — your returns earn their own returns. The early years of an SIP feel slow, but the final years do most of the work because the corpus is largest then.
Consider the ~12% scenario in detail:
- 10-year plan: You invest about ₹52 lakh of your own money to reach ₹1 crore. Roughly half the corpus is your contribution.
- 20-year plan: You invest only about ₹24 lakh of your own money — the other ~₹76 lakh is growth.
- 30-year plan: You contribute barely ₹10 lakh in total, and compounding supplies the remaining ~₹90 lakh.
So a 25-year-old who starts a small SIP can comfortably outpace a 40-year-old forced to invest five to ten times as much each month for the same goal. The cheapest way to reach ₹1 crore is to start now, even with a modest amount you can later increase.
A practical trick: the step-up SIP
Most people cannot commit ₹20,000 a month at age 25, but their income rises over time. A step-up SIP (also called a top-up SIP) lets you increase your contribution by a fixed percentage every year — say 10% — in line with salary growth.
The effect is powerful. A step-up SIP that starts small and grows annually can reach ₹1 crore with a much lower starting amount than a flat SIP, because each raise is invested for many years. If a flat ₹10,000/month over 20 years feels out of reach today, starting at ₹6,000–₹7,000 and stepping up 10% a year can get you to a similar destination. Treat the numbers as directional and recalculate yearly as your actual income changes.
Where do these returns come from?
The 10–14% assumptions in the table only make sense if a meaningful portion of your money sits in equity over a long horizon. Here is how the common Indian instruments compare for a multi-year, ₹1 crore-scale goal:
- Equity mutual funds (including index funds): Market-linked, no guarantee, but the only mainstream option that has historically beaten inflation comfortably over 10+ years. Best suited to long horizons where short-term volatility doesn't matter.
- ELSS (Equity Linked Savings Scheme): An equity mutual fund that also gives a deduction under Section 80C (within the ₹1.5 lakh limit, available only under the old tax regime). It has the shortest lock-in of any 80C option — 3 years.
- PPF (Public Provident Fund): Currently around 7.1% p.a., with EEE tax status (contribution, interest, and maturity all tax-free). It has a 15-year lock-in, a ₹1.5 lakh per year cap, partial withdrawals allowed from year 7, and a rate the government resets every quarter. Excellent for safety, but at ~7% it cannot do the compounding heavy-lifting that the table assumes.
- NPS (National Pension System): Offers an extra ₹50,000 deduction under Section 80CCD(1B), over and above the 80C limit. It blends equity and debt and is geared to retirement, with restrictions on early access.
- Bank FDs: Safe and predictable, but interest is fully taxable at your slab rate, with TDS once interest crosses ₹40,000 a year (₹50,000 for senior citizens). Post-tax returns rarely keep pace with the table's assumptions.
A common approach is to anchor a ₹1 crore goal in equity mutual funds / index funds for growth, use ELSS or NPS if you also want a tax deduction under the old regime, and keep PPF/FD for the stable, lower-risk slice of your overall portfolio.
Don't forget tax on the way out
Building ₹1 crore is only part of the story — what you keep after tax matters too. Under the 2024 rules for equity and equity mutual funds:
- Long-Term Capital Gains (LTCG): Gains above ₹1.25 lakh in a financial year are taxed at 12.5% (holding period over 12 months).
- Short-Term Capital Gains (STCG): Taxed at 20% (holding period of 12 months or less).
Because LTCG is far gentler than STCG, staying invested for the long term is tax-efficient as well as compounding-efficient — another reason the long-horizon columns in the table are so attractive.
A simple action plan
- Pick a realistic return — 10–12% is a sensible planning assumption for an equity-heavy, long-term portfolio; never assume the top of the range.
- Choose your horizon and read the matching monthly SIP off the table, then fine-tune it in the SIP calculator.
- Start now, even if small. A modest SIP today beats a large one delayed by five years.
- Add a 10% annual step-up so your investing grows with your income.
- Review yearly. Recalculate as your salary, returns, and the goal itself evolve, and map it alongside your other goals in the planner.
Frequently Asked Questions
How much do I need to invest monthly to reach ₹1 crore in 20 years? At an assumed ~12% annual return, roughly ₹10,000 per month over 20 years could grow to about ₹1 crore. At a more conservative 10%, you would need closer to ₹13,200. These are illustrative — actual returns are market-linked and not guaranteed.
Is ₹1 crore enough for retirement in India? It depends entirely on your city, lifestyle, age at retirement, and inflation. ₹1 crore today does not have the same value in 25 years, so many people treat it as a milestone, not a finish line. Use the retirement calculator to estimate a goal tailored to your expenses.
Which is better for a ₹1 crore goal — SIP in equity funds or PPF? For a large, long-horizon goal, equity mutual funds generally offer the growth needed, while PPF (~7.1%) is better as the safe, tax-free portion of your portfolio. A blend of both — growth from equity, stability from PPF/FD — is a common strategy. Neither equity returns are guaranteed.
What happens if returns are lower than I assumed? You either fall short of ₹1 crore or take longer to get there. Plan with a conservative return, add a yearly step-up, and review annually. It's safer to over-budget your SIP slightly than to rely on optimistic returns.
