"₹1 crore" sounds enormous, but a SIP turns it into a manageable monthly habit. The single biggest factor isn't how much you earn — it's how early you start. Here are the numbers.
Monthly SIP needed for ₹1 crore (at 12% a year)
| If you invest for | Monthly SIP | You invest |
|---|---|---|
| 10 years | ≈ ₹43,000 | ₹51.6 L |
| 15 years | ≈ ₹19,800 | ₹35.7 L |
| 20 years | ≈ ₹10,000 | ₹24.0 L |
| 25 years | ≈ ₹5,300 | ₹15.8 L |
| 30 years | ≈ ₹2,800 | ₹10.2 L |
Look at the jump: reaching ₹1 crore in 10 years needs about ₹43,000 a month, but stretch it to 30 years and you need just ₹2,800 — and you put in barely a fifth of the money. That gap is compounding doing the heavy lifting. The longer your money stays invested, the more the returns build on previous returns.
Why time beats amount
Over 30 years, you contribute about ₹10 lakh of your own money — the other ₹90 lakh is growth. Over 10 years you have to supply ₹51.6 lakh yourself because there's far less time for returns to snowball. This is the entire argument for starting your SIP today rather than "next year when I earn more."
A step-up makes it easier
You don't have to keep the same SIP forever. A step-up SIP — raising your monthly amount by, say, 10% each year as your income grows — reaches ₹1 crore with a much smaller starting amount. Someone starting at ₹15,000/month with a 10% annual step-up can hit ₹1 crore well inside 15 years, instead of needing a flat ₹19,800 from day one.
What return should you assume?
The table uses 12% a year, a common long-term assumption for equity mutual funds in India. Returns are never guaranteed — some years are great, others negative. Use a more conservative figure (10%) if you want a safety margin, and remember the corpus is an estimate, not a promise.
Run your own number
Want a different target, timeline or return? The retirement calculator works backwards from any goal to the monthly SIP you need, and the SIP and step-up SIP calculators show how a fixed or rising investment grows.
